CI/CD in DevOps: Making Software Delivery Easier

Introduction  In the fast-moving world of technology, delivering software quickly and efficiently is critical. CI/CD—Continuous Integration and Continuous Delivery/Deployment—are practices that help automate the software development process, speeding up releases and reducing errors. This makes it easier for developers and operations teams to work together. Want to learn DevOps With AWS ? Contact Us For more details. What is CI/CD? CI/CD involves two main practices that simplify software development: Continuous Integration (CI): Developers regularly merge their code into a shared repository. Automated tests are run on the code every time a change is made, ensuring everything works properly and bugs are caught early. Continuous Delivery (CD): Once the code passes all tests, it is automatically prepared for deployment. This means the code is always ready to be released. Continuous Deployment: This step goes further, automatically deploying every change to production without manual...
