The 2022 DevOps Roadmap
With references to key resources, an informative route to become a DevOps Engineer and SRE (System Reliability Engineer) in 2022.
Well, what is DevOps, exactly?
This is a typical question that may also be found as a suggested query when searching for DevOps on Google. But, before I get into the concept, let me clarify what DevOps is in simple terms.
DevOps is not a single technology, tool, or tech stack; rather, it is a technique or process in software development that aids in the speedy and successful delivery of software products by ensuring a seamless flow throughout the process. By incorporating DevOps into the company’s workflow, both the development and operations teams will be lot more relaxed.
“DevOps is the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes.” — AWS
Planning->Creation->Verifying->Building->Packaging is the “Dev” part of an application cycle . We have Release->Deploy->Operate->Monitoring of an application in the “Ops” phase. The operations team is in charge of the post-development activities.
Why DevOps?
The main advantage of DevOps is the power of automation which can be adopted in every phase of development.
“Automation applied to an inefficient operation will magnify the inefficiency.” — Bill Gates
In a typical development environment, the development and operations teams collaborate to bring a project to conclusion. In other circumstances, the developer will start working on the next project after writing the code and passing it and its configuration to the operations team for testing and deployment. If an error happened during the deployment of the prior project due to a code bug, the operations team would alert the development team, disrupting the developer’s current project development flow. As a result, DevOps is being used to tackle all of these issues and improve time management. Both the development and operations teams work together in DevOps. Both the development and operations teams will collaborate in the DevOps technique, which will help them reduce project complexity and deliver the product on time.
Advantages of DevOps
Some of the benefits of implementing DevOps in a project are as follows:
Speed
Rapid Delivery
Reliability
Scalability
Improved collaboration
Security
These points may sound similar in terms of technology advantages, but they all help DevOps to distinguish out from other techniques.
DevSecOps
DevSecOps is the addition of the word “Sec” to the above-mentioned DevOps definition.
Security is ensured in every phase of DevOps in DevSecOps, i.e., from planning through delivery, with proper security integrations implemented in each phase. The key advantage of DevSecOps is the ability to produce better secure code/product more quickly.
Benefits of DevSecOps:
Some of the benefits that can be availed when DevSecOps is implemented in a project are:
Rapid delivery of secure code
Security in every phase
Management of vulnerability assessment and patching
Roadmap for DevOps
The road to DevOps is long and winding, with many stops along the way. Because DevOps isn’t a single technology, it’s best to be familiar with all of the most recent tools and frameworks. A never-ending ambition to study and a willingness to keep your information up to date can help you achieve this. Breaking down huge activities into smaller chunks, in my opinion, can help you complete the task much more efficiently.
- Learn Operating systems
Operating systems and their basic concepts are much important when coming to DevOps. Because while dealing with servers it is crucial to know about the topics like Virtualization, Kernels, File and Storage management, etc. Learning Linux is much important in this phase. Understanding Linux commands and learning them will be great.

2. Learn a programming language
It is necessary to know at least one programming language😐. It is not that big deal to pick up one, of course, there will be some difficulties but hey it’ll be great if you learn a programming language like Python, Golang, etc.

3. Learn IT Networking
While dealing with servers it is necessary to ensure inbound and outbound network rules, ports, firewalls. It will be better if you could learn various networking protocols, networking models, routing, bridging, etc. By learning this you can administer and control the networks of the server and can lay specific network configurations for your application.

4. Learn Docker and Kubernetes
Docker and Kubernetes are two important CI/CD tools. It is better to have an idea of containers, container images, container orchestration, packaging, etc.

5. Other CI/CD tools
Continuous Integration and Continuous Delivery/Continuous Deployment (CI/CD) tools are those tools that facilitate the smooth working of both developers and the operation team. Continuous integration deals with code integration by the developer into the main branch of the project repository, while continuous delivery automates the release of the validated code to the public. Many tools help to support this. Some of them are Jenkins, Circle-CI, Nagios, Github Actions, etc.

Only some of the tools are listed here, once you are familiar with this you can try out the relevant and new tools.
6. Cloud Computing
Cloud computing is one of the hottest technology available right now. Most of the mentioned tools and the projects that are adopted by DevOps methodology are cloud-based. Hence it is important to know the basic cloud terminologies and techniques, once you master that you can switch and practice the services provided by the cloud service provider which you are using.
