What is a Linux engineer? Explains work content, annual income, qualifications, current demand, etc.

A Linux engineer is an engineer who specializes in handling Linux among infrastructure engineers. This time, I would like to introduce the detailed work contents, the annual income that you actually get, and the future demand that you are worried about if you aim from now on.

1. What is a Linux engineer?

A Linux engineer is a type of infrastructure engineer, especially a server engineer, and refers to an engineer who specializes in using the OS called Linux.

1.1 Linux engineer definition

Now, I would like to explain the definition of Linux engineer in a little more detail.

■ A type of infrastructure engineer

Linux engineers are occupations that belong to “infrastructure engineers” when classified into major categories. Infrastructure engineers are mainly in charge of IT infrastructure design, construction, management, and transportation, and the occupations called network engineers and server engineers fall under this category of infrastructure engineers. Among these server engineers, engineers who specialize in using Linux are called Linux engineers.

What is an infrastructure engineer? The actual work content, skills, career, qualifications, and future potential are all disclosed!

■ Linux-specific human resources

As mentioned above, a Linux engineer is an infrastructure engineer who specializes in Linux.

Linux is currently the mainstream server OS . The reason is that it uses the GPL (General Public License) license system, which allows you to freely modify and redistribute it, that is, it can be used free of charge. Therefore, it is cheaper and more cost effective than installing a paid server OS.

The fact that you can modify it more freely means that you can see the contents of the code. Therefore, when an error occurs, it has the advantage of being easy to identify where it occurred.

In addition, since the configuration can be changed flexibly, many ultra-lightweight distributions are offered to take advantage of this. Therefore, it is easy to operate lightweight even with low performance equipment.

2. Roles and work contents of Linux engineers

What is a Linux engineer? Explains work content, annual income, qualifications, current demand, etc. [Freelance engineer project information | Professional engineer]

The work of a Linux engineer is as follows.

Requirement definition	Hear customer requests and consider what to configure
design	Consider which hardware to use and what settings to use
construction	Procure and connect the actual machine and set according to the designed contents
test	Make sure it’s done as designed
Operation / maintenance	Monitor the operating status and respond when trouble occurs

2.1 Requirements definition

First, we will hear from the customer about the required functions and performance, and consider what kind of system to build. We will consider the direction of Linux server design and aim to build a highly usable and highly reliable infrastructure. At this stage, a thorough pre-assessment and POC will be conducted to determine the applicability of OSS products, virtualization, and migration.

2.2 Design

Consider the standard configuration. If necessary, perform “security design” and “select driver and firmware versions” while being aware of compatibility with the hardware to be used. Also, the setting values of various servers are decided here. In addition, it is necessary to make detailed decisions such as log management and other measures after the start of operation.

2.3 Build

We will procure the equipment and build it by actually connecting it. We will install his OS (Linux) and middleware (Apache and MySQL) on the server equipment according to the determined standard configuration. Here, it is necessary to firmly build a highly usable and highly reliable infrastructure.

2.4 test

Make a detailed check to see if it works as described in the design document.

2.5 Operation / Maintenance

We monitor the built server every day to see if it is operating normally, and if a failure occurs, we will promptly troubleshoot it.

3. Skills required of Linux engineers

What is a Linux engineer? Explains work content, annual income, qualifications, current demand, etc. [Freelance engineer project information | Professional engineer]

The skills required of Linux engineers are not limited to Linux skills and knowledge. This section introduces the skills required for Linux engineers other than those related to Linux.

3.1 Communication skills

Communication skills are also important for smooth communication with customers and accurate requirement definition.

IT infrastructure is being introduced not only in IT-related industries, but also in services in various fields and scales such as distribution and manufacturing. In other words, not all customers are knowledgeable about IT infrastructure and Linux, so the skills to extract and understand what customers really need are important.

If there is a discrepancy in recognition at the requirement definition stage, it may cause service down or error later, and it may damage the customer.

3.2 High level of understanding and development experience of various open source software (OSS)

In order to meet the various needs of customers, it is also important to have knowledge and utilization skills of various open source software (OSS) other than Linux.

3.3 Assessment

In the work of Linux engineers, there are many projects such as migrating existing systems to Linux and developing systems that meet customer requirements by utilizing OSS.

It is necessary to thoroughly perform an assessment * 1 and PoC * 2 in advance to determine whether OSS products are applicable, virtualizable, and migrateable. In addition, it is necessary to consider and formulate a migration method, evaluate the degree of impact on performance and operation due to virtualization, and formulate a work plan for each process.

Therefore, knowledge that enables accurate assessment is required.

* 1 Assessment: Evaluation of design and migration based on surveys and analysis conducted on the desk, etc.

* 2 PoC (Proof of Concept): Proof of concept = verifying whether new concepts and ideas are feasible

3.4 Business knowledge such as accounting and production control

Especially for business applications, when the purpose is to develop applications such as accounting and production control, the skill to have business knowledge suitable for the site and to compile specifications from the user’s point of view as appropriate. You will need.

3.5 Programming skills

In order to design a system, even non-programmers need to have a good understanding of what programming can do.

Programming skills are also important for Linux engineers, as there are occasions when immediate code correction is required in the field.

4. Qualifications to help Linux engineers

What is a Linux engineer? Explains work content, annual income, qualifications, current demand, etc. [Freelance engineer project information | Professional engineer]

There are two qualifications that can be useful to Linux engineers: Each test has the following characteristics.

• LinuC:
Qualifications that emphasize being in line with business practices in USA

• LPIC:
An international exam that is qualified outside of USA

4.1 LinuC

LinuC is a test that places particular emphasis on being in line with the practices of Linux engineers in USA. Especially for those who want to become an infrastructure engineer in the future , this qualification is especially recommended because it gives them the knowledge necessary for practical work.

What kind of qualification is LPIC? I summarized from the difficulty level to the study method

5. Estimated annual income for Linux engineers

What is a Linux engineer? Explains work content, annual income, qualifications, current demand, etc. [Freelance engineer project information | Professional engineer]

According to the announcement of average annual income.jp, the average annual income of all infrastructure engineers is 5.5 million USD.

In particular, the demand for infrastructure engineers is increasing year by year, and as a result, the average annual income seems to be on the rise due to the shortage of engineers. In some cases, the maximum annual income exceeds 10 million USD.

The average annual income of the above-mentioned “LPIC” holders is 4.5 million USDto 6.5 million USD.

6. The future of Linux engineers

What is a Linux engineer? Explains work content, annual income, qualifications, current demand, etc. [Freelance engineer project information | Professional engineer]

If you want to become a Linux engineer, you may be wondering what will happen in the future even if it is good now. In this article, I would like to introduce the future potential of Linux engineers.

6.1 Demand for infrastructure engineers is stable

Recently, the number of cases where the system is built on the cloud instead of the actual machine has increased, but the demand for Linux is still high.

This is because AWS (Amazon Web Service) , a popular cloud service, offers ” Amazon Linux ” that can be used in much the same way as a type of Linux called ” Cent OS ” . You can also build virtual machines using “Cent OS” on GCP (Google Cloud Platform).

For these reasons, the demand for infrastructure engineers who can handle Linux will not decline in the future.

6.2 Linux is an important skill in the cloud era

LinuC, which is a qualification for Linux engineers, was revised in 2023 to include not only physical servers but also on-premises and public cloud utilization.

Previously, the scope of questions was limited to primitive commands used on physical servers, but after the revision, knowledge of integrated monitoring and automation tools is also required.

In addition, such public cloud engineers are receiving increasing attention, and engineers with Linux expertise used there are also in increasing demand .

The range of questions for LinuC will be revised from April 2023! We interviewed about the difficulty level and the merits of acquiring qualifications.

7. Summary

Infrastructure engineers are a type of job that will continue to be in demand. By deepening your knowledge of Linux, you will be able to apply it more and it will be useful in any field. If you are aiming to become an infrastructure engineer, please learn about Linux as well.

What is DevOps that you often hear? I will explain in an easy-to-understand manner
In recent years, when agile-like development methods have become widespread, the term “DevOps” has become well known.
There is no strict definition for the word DevOps, so people may think differently and have a vague image.
In this article, we will explain in an easy-to-understand manner the concept of DevOps and specific approaches.
1. What is DevOps?
Although the word DevOps has no clear definition, it is widely known with the following implications.
DevOps is a concept that shows various efforts to increase the value of business by developing and operating a system in cooperation with a development team ( Dev elopment) and an operation team ( Operation s ) . So what was the idea behind DevOps in the first place?
1.1 Purpose of DevOps
The purpose of DevOps depends on the environment, but
“Developers and operators work together to provide users with products and services quickly and continuously. ,” depending on the environment .
In the first place, the background to the birth of DevOps is that with the development of the IT industry, the software development period has been shortened, and the need for flexible response to various changes has increased. As a result, the development side
who wants to proceed with development one after another and develop new services, and the operation side who wants to maintain stable service operation. tend to conflict, and various problems are likely to occur.
Therefore, based on the idea of DevOps, there is a movement to increase the value of the business by solving the problems on the development side and the operation side and implementing various efforts to realize DevOps.
The concept of DevOps and specific initiatives are described in the next section.
2. DevOps concept
DevOps is based on the following idea advocated by engineers of the photo sharing service “Flickr”.

[DevOps concept]
◆ Respect Respect
each other . Treating with compassion leads to smooth communication
◆ Trust all members
involved in the Trust system Trust system
◆ Healthy attitude about failure Take a healthy attitude without blaming the
other person for failure person for failure
◆ Avoiding Blame
Do not blame the other person . Don’t blame it because mistakes can happen

In order to realize DevOps, it is important for all team members to fully understand this idea, and for each and every one of them to be aware of it and act toward their goals.
3. Specific DevOps Initiatives
The figure is an example of the process flow that realizes DevOps.
As a concrete initiative, we will release the product in a short cycle, take in feedback from the user while the service is running, automate the series of flow from development plan to implementation, test, deployment, and speedily Make additional features and improvements.
It is possible to proceed efficiently by using various tools suitable for executing each process.
In the next section, we will give a brief explanation of the contents of each process and the tools that are often used to realize DevOps.
3.1 DevOps process
3.1.1 Plan (PLAN)
Determine the requirements for the application to be developed, the execution plan of each process such as infrastructure and monitoring.

3.1.2 Build (BUILD)
It is a process of creating an executable file and a distribution package based on the developed source code.
Often, the series of steps involved in this build is automated.

3.1.3 CONTINUOUS INTEGRATION
Continuous integration is “committing daily developed source code etc. to a configuration management file and automatically executing builds and tests “.
Frequent builds and tests can help you detect bugs early, improve software quality, and reduce software release times.
Continuous integration stands for CONTINUOUS INTEGRATION “CI” .
There is also a technique called CONTINUOUS DELIVERY that automates the entire release process, not just build and test .

3.1.4 Deploy (DEPLOY)
Deploying simply means “making it ready for use” , which makes the files that are made executable by the build workable.
Perform continuous integration and automatically deploy the built application to production if there are no problems.

3.1.5 OPERATE
Here, it is a process also called a “monitor” that monitors the performance of the server and application access, response time, and so on.
Decide what to monitor while considering not to increase the load due to the accumulation of monitoring data.
At the beginning of the introduction, narrow down the items to the minimum necessary.
[Main items to be monitored]
◆ Server CPU usage rate, memory usage rate, number of processes, number of errors
◆ Confirmation of application processes, number of accesses, response time

3.1.6 CONTINUOUS FEEDBACK
Ensure that you continue to receive user feedback, such as by configuring a service desk that you can customize for your users.
This allows you to quickly understand system requests and changes and reflect them in the development process.
3.2 Tools used to achieve DevOps
Many tools are used to effectively implement DevOps.
Each tool has various characteristics, and it is necessary to consider and determine the tool to be used depending on the software to be developed and the combination of multiple tools.
3.2.1 Virtualization tools
◆ Docker
It virtualizes the application execution environment and automatically configures the execution environment.
A lightweight and disposable development environment can be prepared, so you can recreate and rebuild the server at any time.
In addition, since the same thing as the production environment can be reproduced in the development environment, it is possible to test and check the operation in the development environment and reflect it in the production environment as it is.
3.2.2 Configuration management tool
◆ Ansible
◆ Chef
Manages and controls the configuration around the server and infrastructure.
By automating operations such as construction, testing, and operation, efficiency can be improved and work time can be shortened.
3.2.3 CI / CD tools
◆ Jenkins
◆ CircleCI
Automatically run source code builds and tests.
3.2.4 Monitor Tool
◆ Zabbix
◆ Nagios
It automatically monitors servers and applications.
3.2.5 Communication tools
◆ Slack
In order to ensure smooth communication between the development team and the operations team, we use chat tools to communicate in an open situation.
3.2.6 Test automation tool
◆ Selenium
Automation of unit tests, integration tests, application tests, etc. enables improvement of test quality and effective utilization of human and system resources, leading to improvement of software quality.
3.2.7 Source code / version control tools
◆ GitHub
◆ git
Source code and version control are indispensable as the convenience of software increases and the number of frequent changes and additional functions becomes more complicated.
4. Summary
If DevOps can be realized well, it can be developed and operated efficiently, and it has the advantage of being able to provide better services to users quickly.
In order for both sides to work efficiently beyond the boundaries of the development team and the operations team, everyone in the entire organization should clearly understand the purpose of “What is DevOps for?” Toward the same goal. It is important to keep it.
With that attitude in mind, in order to bring DevOps to a level that can be incorporated into actual development and operation, it is good to first gradually understand the mechanism of DevOps and acquire knowledge of the tools to be introduced. Probably.

What is OSS (Open Source Software)? Advantages and precautions when using
OSS is free software that allows you to freely modify or redistribute the source code.
Well-known OSSs include Java, PHP, and Python.
In recent years, IT vendors have often participated, and OSS plays an important role in software development.
This time, we will introduce the basic knowledge and attractiveness of OSS, and the merits of using it.

What is Open Source Software (OSS)?
Open Source Software is an abbreviation for OSS. Software whose source code is open to the public free of charge and whose use, modification, and redistribution are freely permitted.
Contrary to OSS, software that has restricted access to or modified source code is called “proprietary software.” Generally, software source code is intellectual property, so it is sold with a license fee. Most commercial software is proprietary software and the source code cannot be modified.
Typical OSSs include Linux as an operating system, MySQL as a database management system, Java as a programming language, Perl, PHP, Python, and Firefox as a web browser, and are widely used in various fields.
Although OSS is free of charge, many are known to have high performance and high reliability, and companies often develop based on OSS for commercial use. In particular, OSS is indispensable for developers because there is much excellent software in the fields of programming languages and development environments.
The appeal of OSS and why it spreads
Why is OSS so widely used in a wide variety of fields? I will explain the charm of OSS.
● OSI license document
OSS is free software, but it is not without terms and conditions. The Open Source Initiative (OSI), a non-profit organization that certifies OSS, manages OSS licenses. Whether the software is OSS depends on whether the license (Terms of Use) meets the “The Open Source Definition”. Once the license is approved by OSI, the software is officially recognized as open source and bears the “OSI Certification Mark”.

● OSS definition (10 items)
The OSS definition has the following 10 items. Software with a license that complies with these is certified as OSS.
1. 1. Freely allow redistribution
  2. Distribute the source code free of charge
  3. Allow distribution of derivative software
  4. 4. Make it clear which part of the source code is the author’s original code (the integrity of the author’s code)
  . Do not discriminate against individuals or groups
  6. Do not discriminate against the field of use
  7. The rights associated with the program shall be equally granted to all redistributors (license distribution)
  8. Do not license only for specific products
  9. Do not license to limit other software
  10. License is technically neutral

● Reasons for the spread of OSS
OSS has the feature that anyone can freely improve and redistribute. As a result, users around the world cycle through the process of finding, improving, and fixing bugs in the source code. As a result, the stability of the software and the ability to develop high-quality products at a low cost are the reasons why OSS is widespread.
In this way, the idea of advancing development while disclosing product content and information is called the “open source movement.”

Benefits of using OSS
Not only is it free of charge, but there are other benefits to using OSS. Here, we will introduce the advantages of using OSS as a user.

● Reliable
Since the source code is open to the public, it is reliable because it is possible to constantly check for malicious programs and vulnerabilities. Even if a vulnerability is discovered, it is characterized by quick correction.

● High stability
Proprietary software may be terminated or discontinued due to the circumstances of the provider. However, OSS can continue maintenance as long as there are users. Therefore, stable use can be expected for a long period.

● Cost reduction is possible
Since OSS is free of charge, you can expect integrated cost reduction. Not only the initial cost but also the license management after an introduction and the regular replacement cost can be reduced, so it will be useful in software development.

Precautions when using OSS
I will explain the knowledge that you should know when dealing with OSS.

● Must be license compliant
When introducing OSS, it is important to confirm the target license type. OSS is licensed individually for each software. Users are required to use the license in compliance with the license, so be sure to check the OSS license before using it.
In a word, there are various types of licenses, and it is said that there are more than 70 types. For example, when redistributing the software, it depends on the software, such as whether to require the release of the source code and whether to indicate that the source code has been changed. Some licenses limit the purpose of use in the form of “free for research purposes and paid for commercial use”. Therefore, it is important to understand the contents before use.

● Not “free = OSS”
OSS is released free of charge, but not all software available for free is OSS, unless specifically stated as “OSS”. If it is not OSS, you cannot freely modify or redistribute it even if it is free of charge, so be careful when using it.

● Derivatives are also OSS
Derivative works that have been improved and redistributed from OSS are called “derivatives”. Among the OSS license types, the one that requires special attention is the license called “copyleft type”. Copyleft is a term that expresses the idea that “copyleft should be available to everyone, including secondary works while retaining copyright.” GPL, LGPL, CPL, etc. are known as typical copyleft licenses.
The copyleft OSS license states that “improved and redistributed derivatives must be distributed under the same conditions as the original work.” For example, if a developer improves his software based on OSS, he is not free to change to other licenses or terms. In addition, if you modify an OSS that has a copyleft license, you are obliged to publish the source code.

High reliability and versatility are the appeals of OSS
OSS has been developed with high quality and excellent reliability and stability because it can be used secondarily by anyone, and is used by many people.
Another advantage of OSS is that it can be freely customized according to your company’s services and is more versatile than existing software.
In recent years, companies have also developed their products based on commercially available OSS.
OSS is indispensable for software development. When using OSS, make sure you understand the license form and contents before using it well.

What is OSS (Open Source Software)? Advantages and precautions when using
OSS is free software that allows you to freely modify or redistribute the source code.
Well-known OSSs include Java, PHP, and Python.
In recent years, IT vendors have often participated, and OSS plays an important role in software development.
This time, we will introduce the basic knowledge and attractiveness of OSS, and the merits of using it.

What is Open Source Software (OSS)?
Open Source Software is an abbreviation for OSS. Software whose source code is open to the public free of charge and whose use, modification, and redistribution are freely permitted.
Contrary to OSS, software that has restricted access to or modified source code is called “proprietary software.” Generally, software source code is intellectual property, so it is sold with a license fee. Most commercial software is proprietary software and the source code cannot be modified.
Typical OSSs include Linux as an operating system, MySQL as a database management system, Java as a programming language, Perl, PHP, Python, and Firefox as a web browser, and are widely used in various fields.
Although OSS is free of charge, many are known to have high performance and high reliability, and companies often develop based on OSS for commercial use. In particular, OSS is indispensable for developers because there is much excellent software in the fields of programming languages and development environments.
The appeal of OSS and why it spreads
Why is OSS so widely used in a wide variety of fields? I will explain the charm of OSS.
● OSI license document
OSS is free software, but it is not without terms and conditions. The Open Source Initiative (OSI), a non-profit organization that certifies OSS, manages OSS licenses. Whether the software is OSS depends on whether the license (Terms of Use) meets the “The Open Source Definition”. Once the license is approved by OSI, the software is officially recognized as open source and bears the “OSI Certification Mark”.

● OSS definition (10 items)
The OSS definition has the following 10 items. Software with a license that complies with these is certified as OSS.
1. 1. Freely allow redistribution
  2. Distribute the source code free of charge
  3. Allow distribution of derivative software
  4. 4. Make it clear which part of the source code is the author’s original code (the integrity of the author’s code)
  . Do not discriminate against individuals or groups
  6. Do not discriminate against the field of use
  7. The rights associated with the program shall be equally granted to all redistributors (license distribution)
  8. Do not license only for specific products
  9. Do not license to limit other software
  10. License is technically neutral

What is GCP? Explains how to use, what you can do, and merits of introduction by features and services

GCP (Google Cloud Platform) is a cloud service operated by Google. In this article, we will explain the features, how to use each service, what you can do, and the advantages of introduction compared to AWS. If you are interested, please refer to it.

1. What is GCP (Google Cloud Platform)?

GCP is an abbreviation for “Google Cloud Platform,” a cloud service operated by Google. Google operates a search engine “Google” and a video sharing platform “YouTube”, and uses GCP as its infrastructure. In other words, even general companies and individual developers can realize the same infrastructure environment as Google by using GCP.

By the way, GCP is often compared with “AWS” operated by Amazon. Both AWS and GCP are world-famous public clouds, and each company often discusses which one to use when introducing cloud services.

In conclusion, GCP is cheaper for simple services. On the other hand, in terms of robustness and generous Japanese language support, AWS is often favored.

1.1 Examples of typical services of GCP (Google Cloud Platform)

We would like to introduce two typical services of GCP.

■ Google App Engine
Fully managed application platform. The standard application languages available are PHP, Python, Ruby, Node.js, Java, C # and Go.
It also comes with a Docker container that allows you to install your own language and library framework.

■ Google BigQuery
A multi-cloud data warehouse that supports large-scale data analysis. It has a built-in machine learning function and can be flexibly scaled up according to the amount of analysis data.
In addition, according to a survey conducted by The Enterprise Strategy Group, Inc, the total cost of holding large-scale analytics over a three-year period can be reduced by 26% to 34% compared to other cloud data warehouses.

1.2 Is GCP (Google Cloud Platform) charged? free?

GCP has a free tier for each service. Therefore, if you use it within the free tier, you can use it for free.

You will be charged if you use the service beyond the free tier. The fee structure is a pay-as-you-go system, and you will be charged for the excess.

1.2.1 Free trial and free tier

GCP offers two free trials and free slots. A free trial is a free trial service worth $ 300 for 90 days after you start using GCP.

The free tier provides a separate usage amount that can be used free of charge for each GCP service.
As an example, I will introduce a typical App Engine and BigQuery free tier.

■ App Engine

resource	Free allocation
“F” instance	28 hours free per day
“B” instance	Free for 9 hours per day
Data transfer (downlink, outward)	1GB of daily traffic is free

resource	Free allocation
storage	1TB free per month
“B” instance	Free for 10GB per month

1.2.2 Estimated cost

GCP costs are calculated on a pay-as-you-go basis for each product. Please check the official website for details on each product .

An English version of the pricing tool is also available. With this tool, you can simulate costs based on what you use.

▸ Price calculation tool

2. [By service] What you can do with GCP (Google Cloud Platform)

What is GCP? Explaining how to use, what you can do, and merits of introduction by features and services [Freelance engineer project information | Professional engineer]

There are many GCP products and services, and many people don’t know what they can actually do. Here, we will introduce what you can do with GCP for each service that has many GCP users.

Unless otherwise specified, the price list introduced in each item is based on the assumption that the Tokyo region is used.

2.1 Computing

GCP has several computing services that provide scalable virtual machines. Here, we will introduce three services.

2.1.1 Google Compute Engine

Source: Compute Engine ｜ Google Cloud

Google Compute Engine is a service that provides compute resources in the form of IaaS (Infrastructure-as-a-Service). Virtual machines can be combined with OS, CPU, memory, etc. according to the purpose.

In addition, virtual machines are built on Google’s infrastructure, so you can take advantage of large workloads, performance, and stability.

In addition, the cost is a pay-as-you-go system that is charged according to the specifications of the environment and the usage time.

The hourly rate is as follows.

Machine type	Number of virtual CPUs	memory	Fee (US $)	Preemptive fee (US $)
n1-standard-1	1	3.75GB	$ 0.06	$ 0.01
n1-standard-2	2	7.5GB	$ 0.12	$ 0.03
n1-standard-4	Four	15GB	$ 0.24	$ 0.05
n1-standard-8	8	30GB	$ 0.49	$ 0.11

2.1.2 Google App Engine

Source: App Engine ｜ Google Cloud

Google App Engine is a platform for PaaS (Platform-as-a-Service) format application development and hosting. It provides a mechanism to easily start the application.

In addition, the layers below applications such as middleware are completely managed by Google App Engine. Therefore, the feature is that the burden on the developer such as environment update and patch application is reduced.

The hourly rate is as follows.

Machine type	Number of virtual CPUs	memory	Fee (US $)	Preemptive fee (US $)
n1-standard-1	1	3.75GB	$ 0.061	0.01325
n1-standard-2	2	7.5GB	$ 0.122	0.0265
n1-standard-4	Four	15GB	$ 0.244	0.053
n1-standard-8	8	30GB	$ 0.488	0.106

Reference: General purpose machine type family

2.1.3 Google Kubernetes Engine

Google Kubernetes Engine is a cloud service that provides an execution environment for Docker containers. By creating a Kubernetes cluster on Google’s infrastructure and deploying a Docker container, you can deploy the container in seconds.

Two types of operation modes are provided, and the charge system changes depending on the mode.

[Autopilot mode]
This is a fully provisioned cluster configuration mode. Cluster configuration options are created automatically.

[Standard mode]
This mode allows the user to flexibly set the infrastructure.

The hourly rates are as follows. The price will be in Autopilot mode.

3. Benefits of introducing GCP (Google Cloud Platform)

What is GCP? Explaining how to use, what you can do, and merits of introduction by features and services [Freelance engineer project information | Professional engineer]

The benefits of introducing GCP include:

• Infrastructure equivalent to Google search, YouTube, and Gmail can be used
• No initial investment in infrastructure required• Lower overall cost than AWS
• Abundant machine learning related services

I will explain each in detail.

3.1 Google search / YouTube / Gmail equivalent infrastructure can be used

The first advantage of GCP is that you can use the same infrastructure as Google services such as Google search and YouTube / Gmai at low cost.

Google’s services perform large-scale processing speedily, and can be said to be a highly reliable infrastructure.

• Google Search handles billions of searches instantly
• YouTube plays 6 billion hours of video a month
• Gmail provides storage for 425 million users

It takes a huge amount of time and cost to build and operate a highly reliable infrastructure from scratch, but with GCP, you can use it by paying only for what you use when you want to use it, so you can save time and cost.

3.2 No initial investment in infrastructure required

GCP already has a reliable infrastructure, so you don’t have to spend time and money building it in advance. In an on-premises environment, securing a monitoring system and personnel is a bottleneck, but such fixed costs can also be reduced.

3.3 Easy to scale up and down

All GCP services can be scaled up or down according to your needs. Also, depending on the service you are using, if you set it to adjust automatically, it will automatically scale up and down according to fluctuations in the number of accesses and the number of processes.

Charges are also calculated based on machine resource status and usage. Therefore, you will be charged only for what you use, so you do not have to worry about overpayment.

3.4 Overall lower cost than AWS

The cost performance of GCE instances is particularly good, and long-term discounts are automatically applied. In addition, since you can get free credit for 30,000 yen, you can operate it virtually free for the first few months to a year, especially for small sites and apps.

In addition, the server is scalable, so it can handle a rapid increase in access. Since GCP is a service provided by Google, it can also provide other services, and there is also the advantage that it is not complicated because google is the contact point in terms of support.

GCP can reduce operational costs by reducing complex requirements by keeping in mind a simpler design and operation than AWS.

3.5 Abundant services related to machine learning

You can easily get the infrastructure you need to use TensorFlow. TensorFlow is a library released by Google as open source for use in machine learning. All the infrastructure is left to GCP, so you can focus on implementing machine learning algorithms.

4. Disadvantages of introducing GCP (Google Cloud Platform)

What is GCP? Explaining how to use, what you can do, and merits of introduction by features and services [Freelance engineer project information | Professional engineer]

There are two disadvantages to introducing GCP:

• There is little information in Japanese
• There are few regions

The first disadvantage is that there is little information in Japanese.

There are few Japanese translations of GCP official documents, and Japanese translations are a little difficult to read because they are translated by Google Translate. Also, since there are few Japanese engineers who use GCP and there are few technical articles in Japanese, it will be a little difficult for engineers who are not good at English.

The second disadvantage is “fewer regions”. Since there are few regions, it will be necessary to take measures when expanding globally or responding to failures. Also, be aware that the types of services available vary depending on the location of the region.

5. Comparison of GCP (Google Cloud Platform) and AWS (Amazon Web Services)

What is GCP? Explaining how to use, what you can do, and merits of introduction by features and services [Freelance engineer project information | Professional engineer]

You may be wondering which is better, GCP or AWS. The bottom line is case by case. AWS is good for “reliability and robustness”, and GCP is good for “simple and low cost” systems. I will explain in detail.

5.1 AWS if reliability and robustness are required

AWS is feature-rich and flexible, and if you understand the features and build them thoroughly, it will be easier to operate and manage. You can flexibly customize the configuration and security, so if you need reliability and robustness, AWS is a good choice.

However, be careful not to set it too complicated.

5.2 GCP for a simple and low cost system

GCP permission management is simpler and easier to understand than AWS. Therefore, if you want to operate a simple and low-cost system, GCP is a good choice.

However, complicated authority management is not possible, so it is necessary for the administrator to design the policy definition to check the security requirements in advance.

The professional engineers operated by our company have posted a large number of GCP related projects.

There is a need for GCP skills in a wide range of industries, including BI tool development projects for the pharmacy industry and development projects for well-known economic information platforms. With the expected need to operate the cloud at low cost, there will be strong needs for GCP deals.

▸ Search for GCP related deals with professional engineers

8. Summary

This time I explained about GCP. GCP is superior to AWS in terms of cost. However, AWS will be higher in terms of reliability and abundance of information in Japanese.

There is a strong need to operate the cloud at low cost, so strong needs are expected. We hope that you will refer to this article and consider which one is more suitable for you.
