I have officially taken up the #90DaysDevOps Challenge, and today marks the first step in this exciting learning. If you are new to DevOps or looking to sharpen your skills, join me as I summarize the concepts, tools, and strategies that power today’s tech innovations. Let us unlock the future of DevOps together. I am thrilled to begin this journey and excited to share my daily insights with all of you.

What is DevOps?

Imagine you’re organizing a big event, like a concert. There are two main who involved: the event planners and the performers. If these two groups don’t communicate well or work separately, there can be problems. The stage might not be ready when the performers need it, or the lighting might not match the performance.
DevOps is like ensuring the planners and performers work together smoothly from start to finish. It’s a method that helps the people who develop software (like performers) and people who manage the systems it runs on (like planners) collaborate better. It leads to faster and more reliable delivery of the final product.

DevOps is a culture where collaboration, communication, and shared responsibility are key between software developers (dev) and operations teams (ops). This approach helps deliver high-quality software quickly and efficiently.

How does DevOps work?

The DevOps lifecycle is a set of phases that help teams build, test, and deploy software faster and more efficiently. Here’s a beginner-friendly breakdown:

• Plan What it is: Teams plan features and improvements for the software. They discuss what needs to be built, set priorities, and assign tasks.

  Example: Imagine you’re building an app if you plan to add a new login feature.

• Code What it is: Developers write the source code for the software based on the plan.

  Example: When you start coding the login feature you planned earlier, you use tools like Git to manage and track changes.

• Build What it is: Code is compiled and turned into executable software. This is often automated.

  Example: Once the login feature is coded, it’s turned into a runnable program through an automated build system like Jenkins or CircleCI.

• Test What it is: The software was tested to ensure that it worked as expected and there were no bugs.

  Example: Automated tests check if the login feature works correctly, like verifying that users can log in with valid credentials.

• Release What it is: After successful testing, the software is ready to be released to users.

  Example: The new login feature is packaged and prepared to be deployed to the live app.

• Deploy What it is: The software is deployed to production (the live environment where users can access it).

  Example: The new login feature is now available for all users on the app.

• Operate What it is: The software is actively monitored in the live environment. Moreover, issues or performance bottlenecks were addressed.

  Example: If users experience login issues, logs, and monitoring tools help identify the problem to fix it quickly.

• Monitor What it is: Performance and usage data are constantly collected to ensure the system runs smoothly.

  Example: Tools like Prometheus or Grafana monitor the login feature to ensure it’s working efficiently and alert you if there’s an issue.

What are automation, scaling, and infrastructure?

• Automation means using tools to handle repetitive tasks, like testing code, deploying applications, or monitoring systems, without human interference. This speeds up processes and reduces errors.

• Scaling in DevOps involves adjusting resources (like adding more servers or computing power) to handle increased demand automatically. It ensures that applications run smoothly, whether traffic increases or decreases.

• Infrastructure refers to the servers, networks, storage, and software that support the application. In DevOps, infrastructure is often managed through code (called Infrastructure as Code) It makes the application easier to configure, deploy, and maintain.

Why DevOps is important?

• Faster software delivery – Accelerates release cycles and time to market.

• Improved collaboration – Breaks down silos between development and operations teams.

• Automation – Streamlines testing, building, and deployment processes.

• Higher quality and reliability – Continuous testing catches bugs early.

• Enhanced security – Integrates security (DevSecOps) from the start.

• Scalability – Easily scale applications and infrastructure as needed.

• Continuous improvement – Encourages feedback and learning for ongoing optimization.

• Cost savings – Reduces downtime and operational costs through automation.
