Introduction to Code Deployment System

What is a code deployment system?

A code deployment system is a set of processes, tools, and techniques, often referred to as a deployment pipeline or continuous deployment system. It automates the distribution and deployment of software code across various environments, including testing, stagingA staging environment is a controlled environment that closely mimics the production environment. It is used to test and validate code changes, new features, updates, and configurations before they are deployed to the production environment where end-users will access them. , and production environments. Its main objective is to ensure that new code (or code changes) are smoothly and efficiently released from the development environment to the production environment while minimizing disruption and risk.

This lesson introduces the fundamentals of code deployment. We’ll learn key steps in the deployment process, explore common deployment strategies, and understand how to estimate resources and requirements when designing a deployment system.

Steps involved in the code deployment system

A typical deployment system follows these key stages to move code from development to production:

1. Version control: Code deployment process begins with version control, where developers utilize a version control system (such as Git) to manage and track changes made to the codebase.

2. Continuous integration (CI): In a continuous integration phase, code changes from different developers are frequently integrated into a shared repository. Preliminary automated testsThese tests are designed to quickly identify issues in code changes, ensuring that new code additions or modifications do not introduce errors or defects. Preliminary automated tests help catch problems early in the development process, making it easier and less costly to fix them. are executed to ensure that the codebase remains stable and functional.

3. Build phase: After successful integration, a build process is triggered. During this phase, the system compiles the code, resolves dependencies, and generates deployable artifacts or executable files (binaries).

4. Automated testing: The deployment system runs extensive automated tests to check for any regressions or defects that the changes may inadvertently introduce to existing features. Different automated testsAutomatedTests are performed in this phase depending on the organization’s needs and the nature of the software.

5. Staging environment: The code changes are deployed to a staging environment that closely mimics the production environment. This enables additional testing and validation before the software is released to production.

6. Deployment phase: The code deployment system automatically deploys ...
