Mahipal Nehra

Do you know what DevOps is? Wanna follow the roadmap to becoming a DevOps Engineer in 2021? Then, this blog has been designed to help you find out technologies, programming languages, and tools that you can learn this year to become a professional DevOps engineer.

But wait, what is DevOps?

While some of you might be aware of what DevOps is, others might be confused about its accurate definition and the responsibilities involved. So let’s start with the basics!

What is DevOps?

DevOps is the combination of development (Dev) and operations (Ops). It intends to reduce the system development life cycle and offer continuous delivery of a high-quality application. A DevOps engineer collaborates with system admins, developers and other IT staff. DevOps Engineer has in-depth knowledge of automation tools that helps in the development of digital pipelines to handle deployment and other processes.

The responsibilities of a DevOps Engineer include project planning, software development and deployment, security & automation, quality assurance or testing and maintenance & troubleshooting. A team that embraces DevOps becomes better performing, builds more reliable products and provides enhanced customer satisfaction.

But what are the skills & approaches required to become a DevOps Engineer? Let’s check out the roadmap.

The 2021 Roadmap to Become DevOps Engineer

Let’s check the roadmap that will guide you with technologies, tools and languages essential to become a DevOps Engineer in 2021.

1. Programming Language

To become a DevOps Engineer, the first step is to learn a programming language. As it will be useful for integrating databases, debugging codes, or automating the processes of development & deployment.

2. Operating System

An operating system is a program that handles the execution of an application and acts as an interface between the user and computer hardware. It is concerned with the allocation of services and resources like processors, memory, information and devices. Being a DevOps engineer, it becomes essential to learn about operating systems as you will need to work with servers to run applications. Linux is the recommended OS as it’s used by the majority of companies and server providers to run their web applications. However, you can also opt for other operating systems such as:

3. Operating System Concepts

Familiarity with different concepts of operating systems is a must for DevOps engineers as you will be responsible for preparing infrastructure to run an application. Some of the concepts you need to understand are:

  • Process Management

  • Startup Management

  • Threads & Concurrency

  • Sockets

  • POSIX Basics

  • I/O Management

  • Virtualization

  • Memory/Storage

  • File Systems

  • Service Management

  • Networking Concepts

4. Live In Terminals

As a DevOps engineer, having command over the terminal (especially if you are working with Linux or Unix) is crucial. Terminal also known as console or command lines enables developers to automate and accomplish tasks on a system without using GUI (graphical user interface). You need to understand commands for:

  • Text Manipulation

  • Bash Scripting

  • Process Monitoring

  • System Performance

  • Network

  • Compiling Apps From Source

  • Vim/Nano/Emacs/Powershell

5. Networking Security & Protocols

Networking security and protocols help in assuring the integrity and security of data in transition across the network connection. It defines the methodologies and processes to secure the network from unauthorized attempts to extract or view information. Some of the network security protocols you need to know are:

  • HTTPS

  • HTTP

  • FTP

  • SSL/TLS

  • SSH

  • Port Forwarding

  • IPSec & VPNs

  • AT-TLS

  • OSPF Authentication

  • SNMP

  • Firewall

  • Proxy Services

6. Web Server

A web server stores content like text, video, images or application data for a website and provide it to the user when requested. A web server can host one or multiple websites simultaneously using the same hardware and software resources. It communicates with a web browser using HTTP/HTTPS. Understanding its functionality and operation, a DevOps engineer can easily maintain and monitor the server.

A few of the Web Server that you can learn about are:

7. Infrastructure as Code

Infrastructure as Code or IaC is the most important part of DevOps. It helps in provisioning and management of infrastructure (networks, load balancers, connection topology) through code or configuration files rather than manual processes. It allows making the deployment process automated and easier as you can generate the environment as per the requirements.

A few concepts and tools of IaC that you can understand are:

  • Containers

  1. Docker

  2. LXC

  • Configuration Management

  1. Ansible

  2. Salt

  3. Chef

  4. Puppet

  • Container Orchestration

  1. Kubernetes

  2. Mesos

  3. Docker Swarm

  4. Nomad

  • Service Mesh

  1. Istio

  2. Linkerd

  3. Consul Connet

  4. Kuma

  5. Maesh

  • Infrastructure Provisioning

  1. Terraform

  2. CloudFormation

  3. Pulumi

8. CI/CD Tools

Continuous Integration and Continuous Deployment (CI/CD) entails a set of operating principles and practices that enables application development teams to deliver more reliable and frequent updates. Continuous integration deals with code integration by the developer into the main branch of a repository. While continuous development automates the release of the validated code to a repo. Some of the tools one can use for CI/CD are:

9. Infrastructure Monitoring

Infrastructure monitoring is the process of collecting data of your infrastructure to make operational decisions. It uses data generated by servers, applications, network devices and other elements to track metrics like network throughput, hardware capacity and uptime. The insights provided by infrastructure monitoring helps to enhance efficiency, resolve errors by highlighting improvement areas. Tools used for infrastructure monitoring includes:

10. Application Monitoring

Application monitoring is the process of measuring the performance, experience and availability of the application. The data gathered from the monitoring is then used to identify and resolve application errors before they hit users. Software used for monitoring applications are:

11. Logs Management

A log is the detailed list of events that takes place in the system. With log monitoring, a DevOps engineer can evaluate log events to prevent vulnerabilities, improve services, send alerts for bottlenecks. Some tools used for logs management include:

12. Cloud Design Pattern

Cloud design patterns are used to build scalable, reliable and secure applications in the cloud. Each pattern describes the problem addressed and deliberation for applying the pattern. Some of the cloud design patterns are as follows:

  • CQRS

  • Event Sourcing

  • Ambassador

  • Anti-corruption Layer

  • Compute Resource Consolidation

  • External Config Store

  • Gateway Aggregation

  • Gateway Offloading

  • Gateway Routing

  • Pipes and Filters

  • Sidecar

13. Cloud Providers & Packages

As a DevOps engineer, you need to understand the cloud technology, its benefits, requirements, services, providers and the packages concerning your organization. Some of the top-rated and most used cloud services providers are:

You should be aware that the packages these providers offer can vary depending on the number of domains you have, memory, CPU, and SSL Certificates required.

14. Other Technologies

Apart from the above-mentioned tools, techniques and technologies, there are a few more that you need to learn about. The list includes:

Remember, this article is just here to help you set the path and choose what you need to learn next. Indeed, there will be continuous changes in the tools and technologies in the DevOps roadmap in the future. So, try not to get comfortable with your job and always seek to learn about the latest trends and technologies. It will guarantee your career growth as well.
