What is CI/CD Pipeline & What is the Purpose of CICD Tools?
Today’s modern development methodologies demand the use of several tools such as test and build systems, monitoring tools, configuration management, application deployment, and version control. Different tools are required for Continuous Integration, Continuous Delivery, and Continuous Deployment. While it is acceptable to use the same tools for different practices in the CICD pipeline, advanced CICD tools may be required while progressing through the delivery chain.
Before CICD tools, development teams would write code for three to four months. Then they would consolidate their code to release it. The various versions of code would be so diverse and have so many changes that the actual integration was time-consuming and would take months. This process was very unproductive. Hence, it wouldn’t be wrong to say that CICD tools have helped a great deal in boosting productivity.
To understand the function of CICD tools, it is first essential to understand the CICD pipeline. Let’s take a look at it.
Originating from the Extreme Programming methodology, CI is a practice of agile engineering. It has been adopted at large in the DevOps era because automation is required to execute continuous integration favorably. Continuous integration is usually the first step on the road towards DevOps maturity.
Continuous integration involves promptly integrating newly developed code with the main frame of code that is to be released. When the team is set to release the code, Continuous Integration saves a lot of time
The process of Continuous Integration from a DevOps standpoint includes checking your code in, organizing it into the usable code and running some fundamental validation testing.
Continuous delivery is an extension of Continuous Integration; Continuous Delivery is Stage 2 of DevOps. When performing Continuous Delivery, additional automation and testing is done so that the code isn’t merged with the main code line frequently, but you get the code almost ready to deploy with practically no human intervention. Continuous Delivery is hence the practice of keeping the code base continuously in a ready-to-deploy state.
Continuous deployment also known as DevOps nirvana, is the most radical evolution of Continuous Delivery. It involves deploying all the way into production without any human intervention.
Teams that employ Continuous Delivery don’t deploy untested code; instead, before pushing the newly created code into production, it is run through automated testing. The code release only goes to a meager percentage of users, and with the help of an automated feedback loop, quality and usage are monitored before the code is propagated further. As of now, there are a minimal number of companies that are practicing continuous deployment. Netflix, Amazon, Pinterest, and Google are a few of them.
The CICD pipeline is a crucial part of a software development project. If you’re looking for a CICD tool for the purpose of unified functional testing, then Qualitia’s script-less test automation is the perfect solution. Not only does it work exceptionally well as a CICD tool, but is also capable of handling the complexities of salesforce test automation almost effortlessly.
