Implementing API Management: Security, Routing, and Policies

Modern software architectures rely on APIs to connect services, but managing, securing, and scaling these connections can quickly become complex. This structured text-based course guides you through the core principles of API Management, helping you establish a secure and organized gateway for all your backend services. By reading through clear explanations and practical design patterns, you will progress from understanding basic gateway concepts to configuring advanced routing, applying security policies, and optimizing performance. You will gain the confidence to manage APIs at scale and protect your backend infrastructure from unauthorized access and traffic spikes. What you'll learn: Understand the foundational architecture of API gateways and management lifecycles; Configure routing rules to seamlessly connect clients to backend services; Secure your endpoints using modern authentication flows, JWT validation, and rate limiting; Transform request and response payloads on the fly using policy configurations; Implement caching strategies to reduce backend load and improve latency; Monitor API health and usage metrics using modern observability practices. This course begins with essential API terminology and foundational gateway concepts before moving into step-by-step written explanations of policy design, security implementation, and traffic management. It is designed for backend developers, system integrators, and IT beginners looking to manage APIs effectively, with no prior API gateway experience required.
