HOW TO BECOME A DEVOPS ENGINEER – A GUIDE ON DEVOPS ROADMAP FOR 2023

Why DevOps?

  • The goal of DevOps is to increase an organization’s speed when it comes to delivering applications and services. Many companies have successfully implemented DevOps to enhance their user experience including Amazon, Netflix, etc.
  • Facebook’s mobile app which is updated every two weeks effectively tells users you can have what you want and you can have it. Now ever wondered how Facebook was able to do social smoothing? It’s the DevOps philosophy that helps Facebook ensure that apps aren’t outdated and that users get the best experience on Facebook. Facebook accomplishes this true code ownership model that makes its developers responsible that includes testing and supporting through production and delivery for each kernel of code. They write and update their true policies like this but Facebook has developed a DevOps culture and has successfully accelerated its development lifecycle.
  • Industries have started to gear up for digital transformation by shifting their means to weeks and months instead of years while maintaining high quality as a result. The solution to all this is- DevOps.

DevOps Lifecycle

  • DevOps lifecycle is the methodology where professional development teams come together to bring products to market more efficiently and quickly. The structure of the DevOps lifecycle consists of Plan, Code, Building, Test, Releasing, Deploying, Operating, and Monitoring.

  1. Plan: Determining the commercial needs and gathering the opinions of end-user by professionals in this level of the DevOps lifecycle.
  2. Code: At this level, the code for the same is developed and in order to simplify the design, the team of developers uses tools and extensions that take care of security problems.
  3. Build: After the coding part, programmers use various tools for the submission of the code to the common code source.
  4. Test: This level is very important to assure software integrity. Various sorts of tests are done such as user acceptability testing, safety testing, speed testing, and many more.
  5. Release: At this level, everything is ready to be deployed in the operational environment.
  6. Deploy: In this level, Infrastructure-as-Code assists in creating the operational infrastructure and subsequently publishes the build using various DevOps lifecycle tools.
  7. Operate: At this level, the available version is ready for users to use. Here, the department looks after the server configuration and deployment.
  8. Monitor: The observation is done at this level that depends on the data which is gathered from consumer behavior, the efficiency of applications, and from various other sources.

Learn programming languages

As a DevOps engineer, it is crucial to have knowledge of multiple programming languages. The choice of programming language depends on the specific requirements of the project. Here are some of the most commonly used programming languages in DevOps:

Python

  • Python is one of the most popular programming languages among DevOps engineers. It is an easy-to-learn language with a large community and numerous libraries available. Python is commonly used for automation, scripting, and data analysis.

Bash

  • Bash is a scripting language primarily used for automating tasks in the Linux environment. It is the default shell in most Linux distributions and is an essential tool for DevOps engineers.

Go

  • Go is a relatively new programming language that is gaining popularity in the DevOps community. It is fast and efficient and is commonly used for building microservices and web applications.

Ruby

  • Ruby is a high-level language that is easy to read and write. It is often used for scripting and automation tasks in DevOps.

JavaScript

  • JavaScript is a popular language for front-end web development, but it is also used in DevOps for its versatility. It can be used for scripting, building web applications, and automating tasks.

Study operating systems

For the DevOps engineer, it’s necessary to learn about how different operating systems work and their differences, mainly because you’ll be running applications on servers. As such, Linux is typically the go-to solution for this type of thing, used by most companies and server providers. If you’re running a web application, it’s most likely on a Linux server.

  • Linux
  • Unix
  • Windows
  • Ubuntu

OS concepts

Now, operating systems are just one part of the DevOps roadmap. Another is that you must be able to go deep, understanding the underlying OS infrastructure that allows you to run an app. These are called “operating system concepts,” and you need to be familiar with:

  • Startup management
  • Virtualization
  • File systems
  • Memory & Storage
  • Networking
  • Service management
  • Process management

Networking security and protocols

As a DevOps engineer, you must keep the peace. Networking security and protocols will help you ensure the integrity and security of your data. They define the processes and methodologies you’ll use to keep your network secure and safe from unauthorized access attempts.

  • HTTP
  • HTTPS
  • SSL
  • SSH
  • FTP
  • Firewalls
  • TTS
  • IPsec and VPNs
  • AT-TLS
  • Proxy access

Understand Infrastructure as Code

Infrastructure as Code is the practice that allows you to make the deployment process easier and automated as you can generate the desired environment as per the requirements. Meanwhile, Infrastructure as Code lets you manage your IT infrastructure using the configuration files.

  • Docker
  • Containers
  • Ansible
  • Configuration Management
  • Salt
  • Puppet
  • Kubernetes
  • Kuma
  • Terraform
  • Nomad
  • Linkerd

Continuous Integration/Continuous Delivery Tools

The understanding of Continuous Integration/Continuous Delivery (CI/CD) process is probably the most important thing for DevOps Engineers. These can be considered part of the delivery pipeline process. Continuous Integration deals with the integration of code by the developers into the main branch of a common repository. It helps in cost reductions, efficient working, etc.

  • GitHub
  • GitLab
  • Bamboo
  • Jenkins
  • TravisCI
  • Azure DevOps
