DevOps Roadmap

Let’s see the RoadMap important one-by-one steps which help us to learn the essential skills required to become a DevOps.

1. Learn a Programming Language

To get fundamental skills for becoming a DevOps Engineer have knowledge of programming language. On another hand, they are essential for a productive CI/CD process. If DevOps engineers have some programming language basics knowledge then their team uses it to help them understand existing code, review new code, and assist with debugging. So, we have to learn one of the programming languages mentioned below:
You can choose at least one language among them. It will be helpful to write automation scripts.

2. Get Familiar with OS and OS Concepts

This is a part where Ops come in, earlier that it is only supported by the system admin who was responsible for knowing about OS and hardware parts, now developers also need to know them.
Since mostly we use Linux in this field. It’s not necessary to be a Linux magus, fundamental knowledge of OS is required for better outcomes. At least you have to know about Project Management, Sockets, I/O Management, Virtualization, Memory storage, File systems, and so on.

3. Learn to Live in Terminal

For DevOps Engineers, It is significant to have good practice on the command line, especially if you are working on Linux. Developers automate the project processes by using the terminal.
Let know some Linux shell like Bash, or Ksh and tools like find, grep, awk, sed, lsof, networking commands, and so on is mandatory.

4. Networking, Security, and Protocols

In today’s era, everything is connected, making networking and security very important. To be a good DevOps Engineer, you should have to know about basic networking and security concept such as DNS, HTTP, HTTPS, SLS, TLS, FTP, and so on.

5. Knowledge of Infrastructure as Code(IaC)

This is one of the important and vast parts of DevOps. Infrastructure as Code (IaC) refers to the process of managing networks, virtual machines, load balancers, and connection topology in a descriptive model using code or configuration files, rather than performing these tasks manually. By implementing IaC, DevOps practitioners can promote agility, scalability, and a shorter development life cycle.

As a DevOps engineer, it is essential to have knowledge about containers, such as Docker and Kubernetes, configuration management tools like Ansible, Chef, Salt, and Puppet, as well as infrastructure provisioning tools like Terraform and CloudFormation. Here are some recommended courses to learn these tools.

6. Learn some Continuous Integration(CI) and Continuous Delivery (CD) tools

DevOps engineers are responsible for implementing and managing CI/CD pipelines that facilitate faster application testing, build and release quality, and faster feature releases. Various tools are available for CI/CD pipeline management, and a few of them are listed below, which you can learn to enhance your skills:

7. Knowledge of Software and Infrastructure Monitoring

In addition to setup and deployment, monitoring is a critical aspect of the DevOps role. Monitoring software and infrastructure operation can help identify areas of concern, allowing you to optimize performance and rectify bugs.

Several tools are used to monitor infrastructure, including Prometheus, Nagios, Grafana, Datadog, Monit, and Zabbix. For application monitoring, popular tools include Jaeger, NewRelic, AppDynamics, Instana, OpenTracing, and many others.
