API Management

Design, secure, monitor, and optimize application programming interfaces.

More than 90% of modern businesses rely on API management to ensure smooth communication between their applications and services. Yet, many still struggle to fully master these essential tools. Discover how effective API management can transform your IT infrastructure, ensuring security, performance, and scalability.

What is API Management?

API management ensures security, performance, and flexibility of interactions between applications. We implement open-source API gateways, reverse proxies, and service meshes to optimize connectivity and the scalability of microservices across hybrid environments.

API Gateway & Service Mesh Architecture

A production API management topology showing external clients hitting the API Gateway, which enforces authentication, rate limiting, and routing before proxying requests to backend microservices connected via a service mesh.

API Gateway vs Reverse Proxy vs Service Mesh

These three concepts are often conflated, but they serve distinct purposes: A Reverse Proxy (Nginx, HAProxy) operates at Layer 4/7 and handles basic load balancing, TLS termination, and request routing. It knows nothing about API semantics. An API Gateway (Kong, APISIX, Tyk) sits on top of a reverse proxy and adds API-aware features: authentication (OAuth2, API keys, JWT validation), rate limiting per consumer, request/response transformation, analytics, and developer portal integration. A Service Mesh (Istio, Linkerd) handles service-to-service communication inside your cluster. It provides mTLS encryption between microservices, traffic splitting for canary deployments, circuit breaking, and distributed tracing — all without modifying application code. In a mature architecture, you use all three: the reverse proxy at the edge for raw performance, the API gateway for external API consumers, and the service mesh for internal microservice communication.

Main Advantages

1

Enhanced Security and Control

With a well-configured API gateway, it is possible to implement authentication policies, access control, and rate limiting, thereby reducing the risk of attacks.

2

Improved Visibility and Monitoring

Management tools allow for the collection of precise metrics on API usage, facilitating the rapid detection of anomalies or bottlenecks.

3

Performance Optimization

Reverse proxies can accelerate exchanges by managing caching and load balancing between servers.

4

Flexibility in Service Evolution

The use of service mesh facilitates secure communication between microservices and offers advanced capabilities such as intelligent routing or resilience.

Frequently Asked Questions

REST uses fixed endpoints returning predefined data shapes. GraphQL provides a single endpoint where clients specify exactly what data they need, reducing over-fetching and network round trips.

Yes. Our API gateways enforce OAuth2/JWT authentication, TLS encryption, IP whitelisting, and configurable rate limiting at the edge, before requests ever reach your backend.

Yes. We use the Strangler Fig pattern, gradually routing API endpoints from the monolith to new microservices via the API gateway, ensuring zero disruption.

We implement header-based or URL-based versioning strategies with automatic deprecation warnings, ensuring smooth transitions between API versions.

Yes. Our API gateway configurations support subscription tiers, usage metering, and consumer analytics, enabling you to offer paid API access to partners.
