Is DevOps a good career? Yes, DevOps is a good career. But that’s not the question you want an answer to. You want to know if DevOps is a good fit for you. If it is, what would you have to do to be a DevOps developer?

You are in luck; let’s talk about DevOps for a bit.

DevOps Definition

DevOps is an amalgamation of two worlds of technology: development and operations. Most DevOps engineers either start as developers or operations personnel.

A more suitable definition would be…

DevOps is a set of practices aimed at improving collaboration and communication between software development (Dev) and IT operations (Ops) teams.

The goal of the DevOps team is to achieve faster and more reliable delivery of software products.

For better understanding, I’ll put it this way. Imagine yourself as a developer.

“You have spent weeks writing codes for a service or product, then you ship your code onto the server and it doesn’t work right.”

“You are confused and you now have to contact the operations guy to know what in hell is going on.”

That seems like a whole lot of official brouhaha. DevOps is here to bridge that gap. You no longer have to code and ship your code off and expect whatever outcome there is.

DevOps is a completely automated process that fosters a culture of collaboration.

It uses some tools to streamline the software development lifecycle, from planning and coding to testing and deployment.

Now that you understand what DevOps is and its importance, let’s talk about the software development lifecycle and how it is streamlined.

Or you can call it the DevOps Life Cycle.

Software Development Lifecycle

This is how a normal Software Development Lifecycle(SLDC) should look. It goes from analysis to maintenance. Just like a linear activity.

The importance of DevOps is it changes this linear activity into a continuous one. It is a process set in stone that never stops.

DevOps makes it possible for your codes or products to move smoothly from the first stage of planning to the testing, release, and maintenance stages.

Because of DevOps, any negative review can be quickly worked on and implemented. It has combined the key roles of two offices in one powerhouse.

Here are the 5 stages of the DevOps lifecycle.

5 stages of the DevOps Lifecycle.

1. Planning and Analysis

Here, you get to understand the task you’ve just taken on. Most people involved here are non-technical parts of the team such as the product manager, product owner even business analyst.

They give the idea to the team and let it sink in for better results.

After this is done, it is time to share tasks with the appropriate persons.

2. Code

As soon as everyone has gotten their assignments. The Developers begin coding. As the work moves on, the code is sent to a code repository e.g. GitHub.

The code repository is a centralized hub for storing and managing version-controlled source code.

It fosters collaboration among developers.

3. Build and Testing

Now, it’s time to check the performance of the code and do some debugging and general testing.

During this phase, continuous integration occurs, allowing developers to merge code into the branch multiple times a day.

Each merge triggers a code build, followed by a testing sequence.

The objective of this iterative process is to guarantee a safe and deployable product release.

4. Release and Deployment

After the continuous integration phase is complete, it’s time for the continuous delivery phase.

CI to CD.

As soon as the code is compiled, tested and considered safe to deploy, it is time to continually deploy the code onto the servers.

The benefit of this process is it prevents the manual pushing of the product down the pipeline.

5. Operate and Monitor

After monitoring and maintaining the application, it’s crucial to note any issues, and engineers should be available to promptly address them.

This feedback loop then contributes to the planning phase, helping refine and improve future development cycles.

This importance of DevOps shows up in its ability to quickly iterate the software development cycle.

It allows the faster build, release and maintenance of a product.

To understand more about the SLDC, you can take a Scrum Master course. It is very informative and has been broken into sections.

Since you know the details of DevOps and how it is a good career path, here are some skills to learn to be a DevOps Engineer.

1. Version Control

In DevOps, version control is like a track record for your code changes. It helps teams work together smoothly, keeping tabs on who did what and when.

Git is a common tool that makes it easier for developers to collaborate by managing these changes and ensuring code integrity.

To learn version control, start with Git, a widely used system. Follow these steps:

Install Git

Download and install Git on your computer.

Create a GitHub Account

GitHub is a platform that complements Git. Create an account to host your repositories and collaborate with others.

Learn Basic Commands

Familiarize yourself with basic Git commands like clone. These are fundamental for version control.

Understand Branching

Learn about branches in Git. They allow you to work on features or fixes without affecting the main codebase.

Practice on Small Projects

Start with simple projects to apply your Git knowledge. Create, modify, and merge branches to get hands-on experience.

Use Git GUIs

Explore graphical user interfaces (GUIs) for Git, such as GitHub Desktop or SourceTree. They provide a visual representation of version control.

Follow Tutorials

Many online tutorials and courses cover Git basics and advanced topics. Follow them to deepen your understanding.

Collaborate on GitHub

Engage in collaborative projects on GitHub. Contribute to open source or work on projects with others to experience real-world version control scenarios.

Resolve Conflicts

Learn how to resolve merge conflicts, a common aspect of collaboration. Understanding conflict resolution is crucial in a team setting.

Read Documentation

Refer to Git documentation and resources. Understanding the concepts behind version control will enhance your proficiency.

2. Linux

Linux is an open-source operating system kernel that serves as the foundation for various Unix-like operating systems.

It’s known for its stability, security, and flexibility. In the context of DevOps, Linux plays a significant role for several reasons

Linux is open source, meaning its source code is freely available. This aligns with the DevOps culture of collaboration and transparency.

There are several other reasons why Linux is important such as Compatibility, Containerization, Scriptind and Automation.

3. Coding

You need to know at least one major programming language. This would keep you in the loop of things throughout your work life.

I would suggest Python. As it is the most popular programming language there is.

4. Agile Development

This is where your Scrum learning pays off. Agile Development is a timely approach to the delivery of products.

During the sprint, tasks are assigned and progress is supervised during the daily standups.

At the end of the sprint, the codes are pushed out. If any issue is noticed, giddy up for another sprint.

5. Operations

To be proficient in DevOps, you must know servers. You should also include how to maintain them. They are an integral part of DevOps Engineering.

To fully understand operations, Get AWS Certified. You can also get an Associate sysops Certification.

6. Docker and Kubernetes

A normal complaint when working in software development goes like this;

“My code works on my machine. How come it doesn’t work on yours?” or “I can’t get the code you gave me to work”.

Docker helps to curb this problem. It builds a container that allows code to run on every machine without any glitches.

Kubernetes is a container orchestration platform where you deploy the container and you set up networking. All the containers run there. This is the industry standard for DevOps Engineers.

7. Understand Infrastructure As Code

Infrastructure as code is the process of managing and provisioning computer data centre resources through machine-readable definition files.

To understand Infrastructure As Code, You should learn Terraform of Cloud formation.

8. Learn Ansible

Ansible is for configuration management. With Ansible, you can configure not only a single computer but potentially an entire network of computers simultaneously, and no programming skills are needed to use it.

The instructions crafted for Ansible are easily readable by humans, making them accessible whether you’re a novice or an expert in computing.

Apart from Ansible, you can also learn Chef and Puppet.

9. Learn Jenkins

Jenkins automates your entire testing phase by using tools like Junit and Selenium. These tools integrate easily with Jenkins.

They can compile your code every time you push, test and deploy. It’s Continuous Integration and Delivery at the same time.

10. Monitoring

Learn monitoring skills like ELK stack or Grafana. Monitoring is a huge part of DevOps engineering.

A career in DevOps with no experience can be pretty daunting. The reason is, that it is not separate bodies like Dev or Ops, where you can learn from scratch.

With DevOps, you have to understand the fundamentals of both worlds. It can be scary when you look at it as a novice.

It is not impossible though. All you have to do is learn a programming language. After that, don’t dwell too long on coding because you are not going for a developer.

Take other operations courses like Docker, Kubernetes, Ansible, Jenkins etc. With this, you can start your career in DevOps without having prior knowledge of the field.

It is a tough road. But if anyone can do it, it’s you.
