                Harness works and Architecture<\/em><\/strong><\/figcaption><\/figure>\n<\/div>\n\n\n

                Harness utilizes a microservices architecture for its diverse functionalities, enabling scalability, flexibility, and efficient communication between its various modules. Here’s a breakdown of its key components and how they interact:<\/p>\n\n\n\n

                Microservices:<\/strong><\/p>\n\n\n\n

                  \n
                • Modules:<\/strong> Each aspect of the platform (e.g., CI\/CD pipelines, Feature Management, Cloud Cost Management) is handled by a dedicated microservice.<\/li>\n\n\n\n
                • API communication:<\/strong> Services communicate with each other and external tools through a RESTful API.<\/li>\n\n\n\n
                • Independent scaling:<\/strong> Each service can be scaled independently based on its resource needs.<\/li>\n<\/ul>\n\n\n\n

                  Key Components:<\/strong><\/p>\n\n\n\n

                    \n
                  • Harness Controller:<\/strong> Central management plane for configuration, user management, and platform settings.<\/li>\n\n\n\n
                  • Harness Delegate:<\/strong> Deployed on agents in each environment, executes pipeline steps and interacts with cloud providers.<\/li>\n\n\n\n
                  • Harness Modules:<\/strong> Individual microservices like CI\/CD, Feature Management, Cloud Cost Management, etc.<\/li>\n\n\n\n
                  • Kubernetes Integration:<\/strong> Optionally leverage Kubernetes for managing deployments and infrastructure.<\/li>\n<\/ul>\n\n\n\n

                    Workflow and Interactions:<\/strong><\/p>\n\n\n\n

                      \n
                    1. Define your CI\/CD pipelines, feature flags, or other configurations in the Controller.<\/li>\n\n\n\n
                    2. Trigger builds, deployments, or feature rollouts through the Controller or API integrations.<\/li>\n\n\n\n
                    3. The Controller sends instructions to Delegates in the target environments.<\/li>\n\n\n\n
                    4. Delegates execute pipeline steps (e.g., building code, deploying to cloud providers) using specific modules.<\/li>\n\n\n\n
                    5. Modules communicate with each other and external tools as needed (e.g., Git, cloud APIs).<\/li>\n\n\n\n
                    6. Progress, logs, and results are sent back to the Controller and displayed in the UI.<\/li>\n<\/ol>\n\n\n\n

                      Architectural Benefits:<\/strong><\/p>\n\n\n\n

                        \n
