Microservices Architecture

Overview

What is Microservices Architecture?

Decompose monolithic applications into independently deployable Node.js microservices — with event-driven communication via RabbitMQ/SQS, API Gateway orchestration, service discovery, and distributed tracing. Our team brings production-grade expertise to every engagement, ensuring your microservices architecture implementation delivers measurable business outcomes from day one. We architect, build, and maintain solutions that scale with your organisation and satisfy GCC regulatory requirements.

What's included

✓Microservice decomposition strategy and domain-driven design boundary definition

✓Event-driven inter-service communication with RabbitMQ, SQS, and EventBridge

✓API Gateway with routing, auth, rate limiting, and service aggregation

✓Service discovery and health checking with AWS ECS Service Connect or Kubernetes

✓Distributed tracing with AWS X-Ray and structured correlation ID logging

✓Independent CI/CD pipelines per service for zero-downtime autonomous deployments

Key Benefits

Why It Matters

The measurable outcomes our clients achieve with Microservices Architecture.

Independent Deployability

Each service deploys independently — a bug fix in payments never requires a full platform redeploy.

Scale Where You Need It

Scale the search service to 100 instances while keeping the authentication service at 2 — pay for what you actually use.

Blast Radius Containment

A failure in one service does not cascade to others — circuit breakers and async queues absorb failures gracefully.

Technology Flexibility

Each service can use the best technology for its job — Node.js for APIs, Python for ML, Go for high-throughput processing.

Delivery Lifecycle

How We Deliver

A structured, transparent process from kick-off to launch and beyond.

Discovery2 weeks

Domain Analysis & Boundary Definition

Apply domain-driven design to identify bounded contexts, define service boundaries, and produce a phased decomposition roadmap.

Planning1 week

Communication Architecture Design

Design synchronous (REST/gRPC) vs. asynchronous (event-driven) communication patterns and define event schema contracts.

Architecture1–2 weeks

Infrastructure & Orchestration Setup

Provision ECS/Kubernetes cluster, API Gateway, message brokers, and service discovery with Terraform infrastructure-as-code.

Build6–16 weeks

Service Development & Integration

Develop each service with its own repository, CI/CD pipeline, database, and independently deployable containerised runtime.

QA & Security2 weeks

Chaos Engineering & Resilience Testing

Implement distributed tracing, validate circuit breakers, run chaos engineering tests, and confirm blast radius containment.

Launch & ScaleOngoing

Observability, DORA Metrics & Continuous Improvement

Deploy X-Ray distributed tracing, aggregate logs, set up DORA metric dashboards, and establish a service reliability review cadence.
