Continuous Integration/Continuous Deployment (CI/CD)
Building cloud-native apps needs a strong and quick way to deploy them. This is where continuous integration (CI) and continuous deployment (CD) are key. CI/CD automate the build, test, and deployment process. This makes it possible to update your apps quickly and smoothly.
CI/CD means always adding new code and putting it into production automatically. This method helps you:
- Find and fix problems early on
- Lower the chance of mistakes during deployment
- Get new features and updates to users faster
Here’s how a CI/CD pipeline works:
- Continuous Integration: Developers add code to a shared spot, which starts an automated build and test. This checks the code quality.
- Continuous Deployment: If the code passes tests, it goes straight to production. This makes new features or updates available to users right away.
Using continuous integration/continuous deployment makes developing and deploying cloud-native apps faster and more reliable. It also makes your apps more responsive to what users need.
“CI/CD is not just a tool or a process; it’s a mindset that empowers teams to deliver value to customers more quickly and confidently.”
