Microservices: what we know about the design patterns in this architecture

Today, companies must maintain a strong and efficient digital presence. Users interact with applications primarily through mobile devices such as smartphones and tablets, which makes performance, scalability, and user experience critical. To meet these expectations, organizations increasingly rely on microservices architecture as a modern and scalable software design approach.

Microservices architecture is a software design style that structures an application as a collection of small, independent services. Each service is responsible for a specific business capability, can be developed and deployed independently, and communicates with other services through lightweight APIs. This approach improves maintainability, enables loose coupling, and allows small, autonomous teams to own and evolve services efficiently.

Microservices Design Patterns

Designing a microservices architecture requires applying proven design patterns that promote loose coupling, scalability, and clear separation of responsibilities. These patterns are based on principles such as interface segregation, independent deployability, and event-driven consistency.

Some of the most commonly used microservices design patterns include:

• Aggregator Pattern

The Aggregator pattern is used to combine data from multiple microservices into a single response. In this approach, a dedicated service calls several backend services and aggregates their results before returning them to the client. This pattern is especially useful when migrating from a monolithic architecture to microservices, as it keeps services independent while providing a unified output.

• API Gateway Pattern

The API Gateway pattern acts as a single entry point for client requests. It routes requests to the appropriate microservices, handles protocol translation, and can manage cross-cutting concerns such as authentication, authorization, and rate limiting. This pattern simplifies client interactions and reduces coupling between frontend applications and backend services.

• Chain of Responsibility Pattern

According to KnowledgeHut, the Chain of Responsibility pattern allows a request to pass through a sequence of services, where each service performs a specific operation. For example, Service A receives the initial request, enriches it with data from Service B, and then passes it to Service C to produce a consolidated response. This pattern typically uses synchronous HTTP communication.

• Asynchronous Messaging Pattern

Asynchronous messaging enables microservices to communicate without waiting for immediate responses, reducing latency and improving system resilience. This pattern uses message queues or event streams, allowing services to process requests independently and scale more effectively.

For example, if Services A, B, and C are part of a system, client requests can be routed simultaneously to multiple services through a message queue, without enforcing a strict execution order.

• Shared Data Pattern

As explained by KnowledgeHut, the Shared Data pattern involves defining clear database ownership. Each microservice typically manages its own database to avoid tight coupling, while shared or replicated data may be used to address denormalization and performance needs.

This pattern helps solve common challenges such as data duplication, heterogeneous storage requirements, and complex cross-service queries.
