Introduction :
In this, you will see the overview of Continuous Integration and Continuous Delivery. And mainly our focus on the Difference between Continuous Integration and Continuous Delivery. Let’s discuss it one by one.

Continuous Integration (CI) : 
CI, as the name suggests, is an approach that happens before one builds as they are testing code. It requires developers to integrate or merge code into a shared repository continuously. It generally helps one to save more costs in the long run as it is more costly to resolve defects in high-level architecture when defects are discovered later on in the process. It is considered a better way of developing software because it reduces the number of defects when features are merged and solves work on machine problems.  

Continuous Delivery (CD) : 
CD, as the name suggests, is an approach that uses automation to speed the release of new code. In this, teams develop, test, and release software in short cycles as soon as possible. It generally ensures that each change that is made is releasable with complete automation of the release process. One can deliver to production. Its most important factor is the completeness of checks.  

Continuous Integration vs Continuous Delivery :

S.No.

Continuous Integration 

Continuous Delivery  

1.It is a process of integrating code into the mainline code base.  It is a process that involves testing, staging, and deploying code that happens after code is integrated for app changes to be delivered to users. 
2.It is specially designed to regularly integrate code changes into a shared code repository.It is specially designed to ensure that code can be rapidly and safely deployed to production by delivering every change to production.  
3.Its main aim is to provide rapid feedback so that if there is any defect in the code base, it can be identified and resolved as soon as possible.Its main aim is to have a code base that is always ready for deployment to the production environment.  
4.It uses automation to quickly detect problems and assert new code’s correctness before integration.  It uses automation to speed the release of new code.  
5.It is really important as it allows better transparency and farsightedness in the process of software development and delivery. It is really important as it makes us release processes more efficiently and repeatable as much as possible.
6.It generally reduces overhead, builds confidence, provides a consistent build process, mitigates risks, better team communication, etc.  It generally reduces risk and delivers software with fewer bugs, quickly responds to market conditions, releases new to market more frequently, etc.
7.It provides more benefits to developers because allows for code produced to be tested automatically and integrated continuously with other developer’s code and that too with the existing code base.  It provides more benefits to business users because as soon as code is accepted successfully in the CI stage and logical function can be tested, it is released to users. 
8.This process is less complex and less costly as compared to CD.This process is more complex and more costly as compared to CI. 

Conclusion :
In this, we have covered the overview and differences between CI/CD. It is one of the traditional ways of developing software projects. In CI/CD planning, analysis, design, implementation, testing, deploying and maintenance are the main phases.
