Devops Roadmap
Let’s go through the stages of the roadmap one by one. You must have a good command of the programming language. It doesn’t matter which one, but you need it to write automation code. Automation is a core part of DevOps.
You can learn Python, Java, Ruby, Golang, etc. According to the recommendations of the roadmap, you need to understand process management, threads and concurrency, sockets, I/O control, virtualization, memory systems, etc.
Terminal commands are essential for a DevOps engineer, especially if you are running Linux. You should learn commands for monitoring processes, word processing, system performance, and more. By practicing these commands, you should be able to become a master of shell scripting. You should be familiar with the different types of protocols that play an important role in communicating with various devices on the network, such as TCP / IP, HTTP, HTTPS, SMTP, FTP, etc.
In general, a DevOps engineer needs to know how to set up a web server like IIS, Nginx, Apache, and Tomcat. They also need to know about the caching server, load balancer, reverse proxy, firewall, and more. This is one of the most important components in a DevOps engineer training journey. You need to know about application containerization and have a good understanding of container tools like Docker and Kubernetes.
Configuration management tools such as Ansible, Chef, Salt, and Puppet. Other areas include container orchestration and infrastructure configuration. Continuous integration/continuous delivery is now a key part of building a DevOps culture. Therefore, you should be familiar with CI/CD tools, such as Gitlab, Jenkins, Github operations, etc.
With thousands of services running, it is important to ensure that the system is working properly. Both your infrastructure and applications must be continuously monitored. Tools such as SigNoz can help you set up a powerful monitoring system for your application.
Most modern applications are built for cloud computing. So, you need to get to know the leading cloud service providers. AWS, Azure, and Google Cloud are major players, and they also provide free courses on their tools. There is a lot to learn from this ever-changing field. But with good preparation and practice, you can build a solid career in this field that is growing very quickly.
