Hey All! This is Ashlee, a passionate Front-end Developer. In this blog, I give an introduction to DevOps. Please go through it. I hope you all love it.

DevOps is a set of practices and tools organizations use to develop and deliver applications and services faster than usual. It aims at integrating the development and operations teams to enable rapid software delivery.

Using DevOps, software organizations can reduce development complexity, detect and resolve issues faster, and continuously deliver high-quality, innovative software. The ability to work at speed allows organizations to develop a much-needed competitive edge at the same time, serve their customers in a better way.

The two pillars of successful DevOps practice are continuous integration and continuous delivery.

Continuous Integration(CI)

With CI, the developers frequently integrate the codes into a shared repository. Rather than building features separately and submitting them at the end of the life cycle, they continuously integrate the code several times a day. The system starts the compilation process whenever the code is integrated and runs unit tests and other quality-related checks.

CI relies heavily on test suites and automated test execution. When done correctly, it enables developers to perform frequent and iterative builds and deal with bugs early in the lifecycle. This will ensure a better quality of the product that is delivered.

CI aims to simplify the integration process and easily repeatable everyday development tasks to reduce overall build costs and reveal defects early in the cycle. Since, in practice, a developer will often discover integration challenges between new and existing code only at the time of integration, if done early and often, conflicts will be easier to identify and less costly to solve.

Continuous Delivery(CD)

This aims to automate the software delivery process to enable easy and assured deployments into production —at any time. Furthermore, by using an automatic or manual trigger, CD ensures the frequent release of bug-free software into the production environment and hence into the hands of the customers.

CD executes a progressive set of test suites against every build and alerts the development team in case of a failure, rectifying it. In situations where there are no issues, CD sequentially conducts tests. The result is a deployable and verifiable build in an actual production environment.

The main goal of CD is to produce software in short cycles so that new features and changes can be quickly, safely, and reliably released at any time. In addition, since CD automates each step for build delivery, it minimizes the inherent friction points in the deployment or release processes. It ensures safe code release can be done at any moment.

I hope you all like it. This was a concise blog. See you all on the next blog.
