🚀 Understanding CI/CD: Continuous Integration & Continuous Deployment

Hello, everyone! 👋

Today, I'm sharing a simplified guide to CI/CD, covering the essentials of Continuous Integration and Continuous Deployment. But, there's more to CD than meets the eye - we'll also touch on the often-overlooked aspect of Continuous Delivery. Whether you're new to the concept or looking to brush up, this post will help you understand CI/CD in an easy-to-grasp way. Let's get started! 🌟

🤖 Continuous Integration (CI)

Imagine a Library 📚:

• Multiple authors (developers) write books (code) and submit them to the library (repository).
• A librarian (CI tool) collects all the books, checks for errors, and ensures they are properly formatted.
• If a book has errors, the librarian sends it back to the author for corrections.
• Once all books are error-free, the librarian creates a master copy (build) and stores it in the library.

Key Takeaway: CI ensures that individual code changes are integrated into a central repository, and automated processes verify that the code is correct and functional.

🚀 Continuous Deployment (CD)

Imagine a Restaurant 🍽️:

• Chefs (developers) prepare dishes (code) and pass them to the kitchen staff (CD tool).
• The kitchen staff checks the dishes for quality and presentation and then serves them directly to customers (production).
• If a dish is not up to standard, the kitchen staff sends it back to the chef for rework.
• Once a dish is approved, it's immediately served to customers.

Key Takeaway: CD automates the deployment of code changes to production, ensuring that only validated and tested code reaches the end-users.

🏭 Continuous Delivery (CD)

Imagine a Factory 🏭:

• Workers (developers) build components (code) and pass them to the quality control team (CD tool).
• The quality control team checks the components, assembles them into a final product, and packages it for delivery.
• The packaged product is then stored in a warehouse (repository) until it's ready to be shipped to customers (production).
• When the product is shipped, the factory receives feedback from customers, which is used to improve the production process.

Key Takeaway: CD ensures that code changes are built, tested, and packaged into a releasable product, which can be deployed to production at any time. It's a bridge between CI and CD.
