API gateway concepts and patterns
Voir tous les tags
Running an API gateway in production requires more than deploying with default settings. An insecure gateway exposes every backend service to attack, leaks sensitive data, and creates compliance nightmares. This 10-step security hardening checklist covers the critical controls you need before production deployment. Each step includes concrete configuration examples and verification commands.
Kong and STOA both support the Model Context Protocol, but they approach it from opposite directions. Kong added MCP via plugins on its proven Nginx/Lua stack. STOA built MCP into the gateway core from day one. This article compares the two specifically on MCP capabilities — tool discovery, transport, authentication, governance, and agent workflow support — so you can choose the right MCP gateway for your AI agent architecture.
Kubernetes-native API gateway patterns have evolved from simple Ingress controllers to sophisticated multi-mode architectures that support AI agents, service mesh integration, and GitOps workflows. This guide covers the four essential patterns — Ingress Controller, Gateway API, sidecar gateway, and MCP gateway — with architecture diagrams, implementation examples, and a decision framework for choosing the right pattern for your use case.
10 practical security steps that take less than a day and prevent 95% of API incidents. No enterprise budget, no complex tooling — just engineering discipline. Covers secrets, rate limiting, CORS, auth, TLS, logging, and dependency management.
You're a freelancer. You shipped an API for a client. It works. Tests pass. Invoice sent.
Six months later, the client calls: someone scraped their entire user database through your API. No rate limiting. No input validation. Default CORS headers. The API key was in the frontend JavaScript.
This happens more often than anyone admits. And it's almost always preventable with a simple checklist. This is part of our open-source API management philosophy: security should be accessible to everyone, not just enterprises.
Migrating from Axway API Gateway to an open-source alternative is a structured process that can be completed in 4-6 months using a phased, zero-downtime approach. This guide provides a feature mapping, migration roadmap, and practical advice for enterprise teams evaluating their options.
Every REST API endpoint can become an MCP tool that AI agents discover and invoke automatically. The conversion is a mapping exercise: your OpenAPI spec already contains the tool name, description, parameters, and endpoint URL that MCP needs. This guide walks through the process from a single endpoint to bulk automation using ToolSet CRDs.
AI agents need a secure, standardized way to access your APIs. The Model Context Protocol (MCP) provides that bridge, and STOA Platform makes it trivial to deploy. In this tutorial, you'll learn how to set up a production-ready MCP gateway using Docker Compose in under 10 minutes.
New to MCP gateways? Start with our comprehensive guide: What is an MCP Gateway? to understand the architecture and security model before deploying.
By the end of this guide, you'll have a running gateway that exposes your existing REST APIs to AI agents like Claude, connects to authentication, and enforces runtime policies.
WSO2 API Manager is an established open-source API management platform used by enterprises worldwide. As the API management landscape evolves — with AI agent protocols, Kubernetes-native architectures, and stricter European regulations — some teams are evaluating alternatives that better align with their current requirements. This guide provides a feature comparison, migration approach, and practical guidance.
Migrating from a legacy API gateway is one of the highest-stakes infrastructure projects an enterprise platform team can undertake. Done well, it eliminates years of accumulated technical debt, reduces licensing costs, and opens the door to AI agent integration. Done poorly, it disrupts production APIs and erodes trust with every team that depends on the platform.
This guide provides a vendor-neutral framework for planning and executing an API gateway migration in 2026 — covering assessment, policy translation, phased traffic migration, and the new requirements introduced by AI agents. Specific guidance for individual platforms (Broadcom Layer7, Software AG webMethods, Axway, Apigee) is linked throughout.
Migrating from Software AG webMethods API Gateway™ to an open-source alternative is achievable in 4-6 months using a phased, zero-downtime approach. This guide covers what makes webMethods migrations distinct — the Integration Server (IS) dependency, the Designer-based policy model, the IBM licensing entanglement — and provides a concrete roadmap for platform teams ready to act.
