DevOps. Many people have heard about this famous profession. Let’s figure out who this is!

DevOps is the short version of Development Operations. It is a methodology, culture, and already a modern “philosophy” of software delivery, where there is an active interaction between all the specialists, integration of processes between each other, active exchange of knowledge.

This methodology involves combining development, integration with other applications, testing, and operation of the product. The DevOps approach ensures continuous data exchange and transparency between application development teams (Dev) and their IT counterparts (Ops). As an added benefit, this practice helps eliminate communication barriers between groups involved in software delivery.

The DevOps approach provides a continuous feedback loop to all participants in the development process. for further improvement, development, testing, and deployment. One result of these efforts can be the faster implementation of needed changes or additional features. DevOps practices drive software delivery optimization and business innovation

DevOps engineers have emerged through this approach. This is a new level of evolution of the systems engineer — the “systems engineer version 2.0”. These are specialists who work with software, servers, and networks, understand the software development lifecycle, and know how to program themselves.

In order to become a DevOps engineer, you need to be confident in handling operating systems, know 1–2 programming languages, and understand cloud technologies. A DevOps engineer should be able to navigate many products, correctly apply modern tools and approaches to solve classic operational tasks. DevOps must have a broad outlook and also constantly learn. Let’s look at this issue in more detail.

DevOps engineers should know:

Programming languages. The automation process involves writing scripts and, in some cases, programs. Now the most common in the DevOps-sphere are Python, Go, and Bash.

Operating systems. Basic knowledge of the major operating systems is required. In-depth knowledge of Windows and Linux.

Cloud technologies. Provide development migration and data migration to the cloud, as well as IT infrastructure cost optimization. DevOps engineers must know and understand the solutions and tools that exist today on cloud platforms. These are Amazon Web Services, Microsoft Azure, and Google Cloud.

CI/CD methodology. It allows you to automate the integration of code into repositories, as well as building, testing, and launching software applications in production.

Version control methodology. It allows you to keep track of code corrections and the history of changes, which simplifies its analysis and recovery. The most famous version control system is Git;

Microservices and orchestration systems. Containers and microservices are actively used today to ensure the delivery and deployment of software. Orchestration systems are used to manage containers, the most popular being Kubernetes.

Networking, security, protocols. These are network protocols for sending e-mail, cryptographic protocols SSL/TLS, understanding the difference between HTTP and HTTPS, the protocol of file transfer over the network FTP, the protocol of remote server management SSH, and technology Port Forwarding.

At first glance, it may seem like a lot and will be difficult to master. We know how to master this knowledge correctly and step-by-step.

So, how to become a DevOps engineer.

1. You need to start with the basics — it’s networking, security, protocols. This is studied in the Computer Networks course, which is part of the systems engineer training program. This will help you understand encryption and data transfer protocols.

2. Understand the major operating systems — Windows and Linux, know the nuances, know how to work with a data collection terminal.

3. Learn the basic level of one of the programming languages — Python, Go, Bash, but also C, C++, Rust, Ruby, Node.js will do. The given knowledge will allow automating processes, writing necessary scripts and programs.

4. Learn to work with popular containerization tools Docker and Kubernetes orchestration.

5. Cloud services — the most popular ones are Amazon Web Services, Microsoft Azure, and Google Cloud.

We are preparing a course for DevOps now! We separate this course for modules for easier understanding. For best quality knowledge, that will be very useful. The first module is ready now! You can find additional information on our website!

Each of our students will receive a mini English course as a bonus. Our course is an online platform, so you can study from everywhere.
