An agreement level document for microservices is a comprehensive and detailed document that outlines the terms, conditions, and agreements between different microservices within a system. It serves as a contract or agreement among these microservices, ensuring seamless integration, collaboration, and understanding of responsibilities, communication protocols, and data formats. This document defines the agreed-upon standards, interfaces, and expectations for the microservices. Keywords: 1. Agreement level document: A formal document that defines the agreement among microservices. 2. Microservices: Autonomous, independent, and loosely coupled services that work together to build a complex application. 3. Integration: The process of combining and connecting microservices to create a functional system. 4. Collaboration: Cooperation and interaction between microservices to achieve desired outcomes. 5. Responsibilities: Specific tasks and duties assigned to each microservice. 6. Communication protocols: The rules and methods for exchanging information and interacting between microservices. 7. Data formats: The structure and organization in which data is stored and exchanged between microservices. Different types of Agreement level document for microservices may include: 1. Service Level Agreements (SLAs): These documents define the agreed-upon levels of service, performance metrics, availability, and response times between microservices. SLAs ensure that each microservice meets the performance and availability expectations defined by the system as a whole. 2. API Contracts: Microservices communicate with each other through APIs (Application Programming Interfaces). API contracts outline the agreed-upon structure, parameters, and behaviors that microservices should adhere to when interacting with each other. 3. Data Governance Agreements: These agreements specify the rules, standards, and policies regarding data ownership, access, security, and privacy between microservices. They ensure that data is handled consistently and securely across the system. 4. Operational Agreements: These agreements define the responsibilities and expectations for operational tasks, such as monitoring, logging, error handling, and troubleshooting for each microservice. They ensure consistent operational practices across the system. 5. Dependency Agreements: Microservices often rely on other microservices or external dependencies. Dependency agreements outline the requirements, expectations, and procedures for integrating and interacting with these dependencies, ensuring proper functionality and reliability. In summary, an agreement level document for microservices is essential for ensuring seamless collaboration, integration, and communication between microservices. It specifies the terms, conditions, and agreements related to performance, APIs, data governance, operational tasks, and dependencies. Different types of agreements, such as SLAs, API contracts, data governance agreements, operational agreements, and dependency agreements, may exist depending on the specific requirements and nature of the microservices' architecture.
