Also known as

• Fault Tolerance Switch

Intent of Circuit Breaker Design Pattern

The Circuit Breaker pattern is a critical Java design pattern that helps ensure fault tolerance and resilience in microservices and distributed systems. Using Circuit Breaker, it is possible to prevent a system from repeatedly trying to execute an operation likely to fail, allowing it to recover from faults and prevent cascading failures.

Also known as

• Distributed Transaction Commander
• Transaction Coordinator

Intent of Commander Design Pattern

The intent of the Commander pattern in Java, especially in the context of distributed transactions, is to manage and coordinate complex transactions across multiple distributed components or services. This pattern ensures data consistency and integrity in distributed systems, making it crucial for microservices architecture. It encapsulates transaction commands and coordination logic, facilitating the implementation of distributed transaction protocols like two-phase commit or Saga.

Also known as

• Health Monitoring
• Service Health Check

Intent of Health Check Design Pattern

The Health Check pattern in Java is designed to proactively monitor the health of individual software components or services, allowing for quick identification and remediation of issues that may affect overall system functionality in microservices architectures.

Also known as

• API Composition

Intent of Microservices Aggregator Design Pattern

The Microservices Aggregator pattern helps aggregate responses from multiple microservices into a single unified response, optimizing client-server interactions in scalable systems.

Intent of Microservices API Gateway Design Pattern

The API Gateway design pattern aims to provide a unified interface to a set of microservices within a microservices architecture. It acts as a single entry point for clients, routing requests to the appropriate microservices and aggregating results, thereby simplifying the client-side code.

Intent of Client-Side UI Composition Design Pattern

Compose user interface from independently deployable microservices on the client side for greater flexibility and decoupling.

Also Known As

• UI Aggregator
• Frontend-Driven Composition

Detailed Explanation of Client-Side UI Composition Pattern with Real-World Examples

Intent of Microservices Distributed Tracing Design Pattern

Provide a mechanism to trace and correlate requests as they traverse multiple microservices in a distributed system, enabling end-to-end visibility and easier troubleshooting.

Also known as

• Distributed Request Tracing
• End-to-End Microservice Tracing

Also known as

• Idempotent Subscriber
• Repeatable Message Consumer
• Safe Consumer

Intent of Idempotent Consumer Pattern

Ensure that consuming the same message multiple times does not cause unintended side effects in a microservices-based architecture.

Also known as

• Centralized Logging
• Log Management

Intent of Microservices Log Aggregation Design Pattern

Log Aggregation is a crucial microservices design pattern that centralizes the collection, storage, and analysis of logs from multiple sources, facilitating efficient monitoring, debugging, and operational intelligence.

Intent of the Publish-Subscribe Design Pattern

Defines a one-to-many dependency between objects, enabling automatic notification of multiple subscribers when a publisher's state changes or an event occurs.
