Architecture Methodology

Microservices Architecture

Build scalable, resilient systems with independently deployable services that enable rapid innovation and team autonomy.

Core Principles

Service Independence

Each microservice is independently deployable, scalable, and maintainable with its own data store and business logic.

Faster deployment
Team autonomy
Technology diversity

API-First Design

Services communicate through well-defined APIs, enabling loose coupling and technology-agnostic integration.

Clear contracts
Easy integration
Version management

Database per Service

Each service owns its data, ensuring loose coupling and enabling independent scaling and technology choices.

Data isolation
Schema evolution
Optimal databases

Cloud-Native

Built for cloud platforms with containerization, orchestration, and infrastructure as code.

Auto-scaling
High availability
Cost optimization

Architecture Components

Essential building blocks for microservices ecosystem

API Gateway

Single entry point for all client requests with routing, authentication, and rate limiting

Request routingLoad balancingAuthenticationRate limitingAPI composition
Kong, AWS API Gateway, NGINX

Service Mesh

Infrastructure layer for service-to-service communication with observability and security

Service discoveryLoad balancingCircuit breakingDistributed tracingmTLS encryption
Istio, Linkerd, Consul

Event Bus

Asynchronous messaging for event-driven architecture and service decoupling

Pub/Sub patternsEvent sourcingCQRS supportMessage persistenceDead letter queues
Kafka, RabbitMQ, AWS SQS

Service Registry

Dynamic service discovery and health monitoring for microservices ecosystem

Service registrationHealth checksDynamic discoveryLoad balancingFailover support
Consul, Eureka, etcd

Design Patterns

Proven patterns for microservices challenges

API Gateway Pattern

Medium

Single entry point for client requests with routing and aggregation

Simplified client, security enforcement, request aggregation

Circuit Breaker

Low

Prevent cascading failures by failing fast when services are down

Improved resilience, faster failure detection, graceful degradation

Saga Pattern

High

Manage distributed transactions across multiple services

Maintain data consistency, handle long-running transactions

CQRS

High

Separate read and write operations for optimal performance

Scalable reads, optimized queries, eventual consistency

Event Sourcing

High

Store state changes as sequence of events

Complete audit trail, time-travel debugging, event replay

Sidecar Pattern

Medium

Deploy helper components alongside main service container

Separation of concerns, reusable components, polyglot support
