Today, the market scenario has totally changed.

Technology is transforming and everything is available with a single click.

But the one thing meant to be difficult

Well, the answer is :

Building and releasing software 

It can be a cumbersome process, especially for application teams and also difficult to deploy infrastructure..

Oftenly, challenges come in many projects but one has to overcome those challenges in order to grow the projects

So, to deal with those challenges and release the software in a quick and consistent way

Developers have created an amazing pipeline that basically manages the automated processes very easily.

It is CICD: Continuous Integration Continuous Deployment

Basically, these are two concepts but both are used interchangeably. Sometimes we called it continuous delivery in place of continuous integration

Let’s deep dive into it and see what is it all about?

Continuous integration The CI a part of CICD is often summarized with: you would like all parts of what goes into making your application attend an equivalent place and run through an equivalent process with results published to simple to access place.

The simplest example of continuous integration is some things you would possibly not have even thought of being significant: committing all of your application code during a single repository! While this will appear to be a no-brainer, having one place where you “integrate” all of your code is the foundation for extending other, more advanced practices.

Once you've got all of your code and changes getting to an equivalent place, you'll run some processes thereon repository whenever something changes. This might include some of the best practices like :

• Run automatic code quality scans thereon and generate a report of how well your latest changes adhere to good coding practices
• Build the code and run any automated tests that you simply may need to be written to form sure your changes didn’t break any functionality
• Generate and publish a test coverage report back to get a thought of how thorough your automated tests are
• These simple additions (made easy with tooling which will be mentioned later) allow you, the developer, to specialize in writing the code. 

But there is a hidden climax:

A central repository code is there which allows you to receive the changes thereby managing your automated processes with respect to building, testing and scanning those codes easily while generating reports.

Why is continuous integration helpful?

• The idea is to attenuate the value of integration by making it an early consideration. In the DevOps world, developers can figure out the conflicts around the boundaries between multiple codes and therefore conflicts can be minimized effectively. Once the conflict is resolved, work can continue confidently that the new code honors the wants of the prevailing codebase.
• Integrating code frequently doesn't, by itself, offer any guarantees about the standard of the new code or functionality. In many organizations, integration is expensive because manual processes are wont to make sure that the code meets standards, doesn't introduce bugs, and doesn't break existing functionality. Frequent integration can create friction when the extent of automation doesn't match the quantity of quality assurance measures in appropriate places.

But let me clear you:

• The technical goal of Continuous integration is to create an automated and consistent platform to build and test the applications so that in the future, they all run smoothly.
• To address this friction within the mixing process, in practice, continuous integration relies on robust test suites and an automatic system to run those tests. When a developer merges code into the most repository, automated processes begin a build of the new code. 
• Afterward, test suites are run against the new build to see whether any integration problems were introduced. If either the build or the test phase fails, the team is alerted in order that they will work to repair the build.

So previously we have discussed one part of the CICD pipeline

Now, let's move to our last part which is:

Continuous Deployment

Although, deploying code can become challenging for you but you know every system has its pros and cons, right?

But what exactly it is :

Continuous deployment is an extension of continuous delivery that automatically deploys each build that passes the complete test cycle. rather than expecting a person's gatekeeper to make a decision what and when to deploy to production, the endless deployment system deploys everything that has successfully traversed the deployment pipeline. confine mind that while new code is automatically deployed, techniques exist to activate new features at a later time or for a subset of users. 

Deploying automatically pushes features and fixes to customers quickly, encourages smaller changes with limited scope, and helps avoid confusion over what's currently deployed to production.

This fully automated deployment cycle is often a source of hysteria for organizations worried about relinquishing control to their automation system of what gets released. The trade-off offered by automated deployments is usually judged to be too dangerous for the payoff they supply.

Why is continuous deployment helpful?

• You develop much faster as soon as the code is used by your users. If in case, there is a bug then it's in the code you just developed. You can go back and fix it whenever you can.
• Continuous deployment gives flexibility as your DevOps team is making small changes which you can easily prioritize on what they are working for.
• You can also do A/B split testing because CD focuses on an experimental approach. CD makes software developed much faster which leads to higher quality products and results in happier customers out there. 

Conclusion:

In today’s guide, we understand the CICD pipeline which basically is used to build and test the software safely and securely. These processes typically work on an automation and give room to fix and detect codes easily.
