ENTERPRISE API GATEWAY SOLUTIONS

An API Gateway acts as the single entry point for all client requests, providing a unified interface to your backend services. It handles authentication, rate limiting, request routing, load balancing, caching, protocol transformation, and monitoring—offloading these concerns from your microservices. Our API Gateway implementation services include Kong Gateway setup with plugins, AWS API Gateway with Lambda integration, Tyk configuration, developer portal creation, API analytics dashboards, and multi-environment (dev/staging/prod) management. Perfect for microservices architectures, SaaS platforms, or any organization with multiple backend APIs requiring centralized governance.

WHO IT'S FOR

Essential for microservices architectures, large-scale SaaS platforms, enterprise systems with multiple APIs, organizations requiring centralized security and governance, and teams managing APIs for external developers.

09

Developer Portal

Self-service API documentation, interactive API explorer (Swagger UI), API key generation, usage analytics dashboard, onboarding guides, and support ticketing.

10

API Analytics

Request/response metrics, latency tracking, error rate monitoring, top consumers dashboard, geographic distribution, endpoint popularity, and custom metrics.

11

Multi-Environment Management

Separate dev/staging/production gateways, environment-specific configurations, config promotion workflows, environment variables, and isolated testing.

12

Security & Compliance

IP whitelist/blacklist, CORS policies, request size limits, bot detection, DDoS protection, WAF integration, audit logging, and PCI DSS compliance.

HOW WE DO IT

1

Architecture Assessment

Analyze existing APIs, identify microservices, define routing requirements, plan authentication strategy, estimate traffic patterns, and select gateway platform (Kong/AWS/Tyk).

2

Gateway Installation

Deploy Kong/AWS API Gateway, configure database/storage, set up admin API, install plugins, configure load balancer, and enable SSL certificates.

3

Service Registration

Register backend services as upstreams, configure routing rules, set up health checks, implement load balancing algorithms, and test connectivity.

4

Plugin Configuration

Enable authentication plugins (JWT, OAuth), configure rate limiting, set up caching, add logging plugins, implement request transformations, and test each plugin.

5

Developer Portal Setup

Deploy developer portal (Kong Dev Portal or custom), generate API documentation, create API key provisioning, build usage dashboards, and publish onboarding guides.

6

Monitoring & Production

Set up Prometheus/Grafana for metrics, configure CloudWatch alarms, enable error tracking, perform load testing, deploy to production, and train operations team.
