    Study Notes

    Architecture Microservices

    Service Discovery

    • A mechanism that allows services to find and communicate with each other
    • Enables dynamic registration and deregistration of services
    • Types:
      • Client-side discovery: clients are responsible for service discovery
      • Server-side discovery: a centralized registry is used
    • Techniques:
      • DNS-based service discovery
      • Registry-based service discovery (e.g., etcd, ZooKeeper)
      • Peer-to-peer service discovery

    Event-driven Architecture

    • A software architecture pattern that focuses on producing and handling events
    • Components communicate with each other by publishing and subscribing to events
    • Characteristics:
      • Loose coupling between components
      • Asynchronous communication
      • Scalability and flexibility
    • Benefits:
      • Improved system resilience and fault tolerance
      • Easier integration of new components
      • Enhanced scalability and performance

    API Gateway

    • A single entry point for clients to access microservices
    • Acts as a reverse proxy, routing requests to the appropriate service
    • Responsibilities:
      • Authentication and authorization
      • Rate limiting and quota management
      • API key validation
      • SSL termination
      • Load balancing
    • Benefits:
      • Simplified client-side complexity
      • Improved security and governance
      • Enhanced scalability and performance

    Micro Frontend

    • An architectural approach that extends microservices to the frontend
    • Each feature or component is developed, deployed, and scaled independently
    • Characteristics:
      • Independent deployment and scaling
      • Autonomous teams and development
      • Integration through APIs and events
    • Benefits:
      • Improved scalability and resilience
      • Faster time-to-market for new features
      • Enhanced flexibility and customization

    Containerization

    • A lightweight and portable way to deploy applications
    • Containers share the same OS kernel as the host
    • Benefits:
      • Isolation and sandboxing
      • Efficient resource allocation
      • Rapid deployment and scaling
    • Popular containerization technologies:
      • Docker
      • rkt
      • Open Container Initiative (OCI)

    Domain-driven Design (DDD)

    • An approach to software development that focuses on the core business domain
    • Emphasizes understanding the business domain and modeling its concepts and processes
    • Key concepts:
      • Bounded contexts: autonomous domains with their own models
      • Entities: objects with identity and state
      • Value objects: immutable objects with a set of values
      • Aggregates: clusters of objects that can be treated as a single unit
    • Benefits:
      • Improved communication between business stakeholders and developers
      • More accurate modeling of the business domain
      • Enhanced maintainability and scalability
