Custom API & Microservices Integration

Overview

Custom API & Microservices Integration transforms monolithic applications into agile, independently deployable services. By defining clear service boundaries and leveraging REST, GraphQL, or gRPC endpoints—alongside robust connectors for third-party APIs and message brokers like Kafka or RabbitMQ—this architecture enables scalable growth, simplified maintenance, and resilient communication across business domains.

Key Benefits

Rapid Feature Deployment

Independent services allow new functionality to roll out without impacting the entire system.

Seamless 3rd-Party Integration

Connect effortlessly with external services and data providers through standardized API adapters.

Event-Driven Messaging

Kafka or RabbitMQ-based streams support asynchronous, scalable inter-service communication.

Strong API Contracts

OpenAPI/Swagger or GraphQL schemas ensure reliable data consistency and clear versioning.

Polyglot Flexibility

Each service can leverage the optimal language or framework—Go, Node.js, .NET Core, or Python.

Enhanced Resilience

Service meshes (e.g., Istio) and circuit breakers boost fault tolerance and uptime.

How It Works

1

Domain Modeling

Workshops identify business capabilities and isolate data flows.

2

API & Integration Design

Define REST, GraphQL, or gRPC schemas; specify connectors for third-party APIs and Kafka/RabbitMQ.

3

Service Development

Implement microservices, containerize with Docker, and orchestrate via Kubernetes.

4

Integration Testing

Employ contract testing (Pact) and end-to-end test suites to validate inter-service and external integrations.

5

Deployment & Monitoring

Automate with CI/CD pipelines and establish observability using Prometheus, Jaeger, and broker-specific dashboards.

Deliverables

Service boundary diagrams and domain model documentation
OpenAPI/GraphQL schema files and API reference guides
Docker images and Kubernetes Helm charts
Contract testing reports and integration test suites
CI/CD pipeline configurations
Monitoring dashboards and distributed tracing setup
