Overview
As organizations continue to build APIs for applications, integrations, AI platforms, and agents, managing those APIs becomes increasingly important. Whether you're exposing a custom business application, Azure Function, Logic App, or Azure AI Foundry model, simply publishing an endpoint is rarely enough. Organizations need a way to secure, govern, monitor, and scale API access without exposing backend services directly to end users and applications. This is where Azure API Management (APIM) comes in.
Azure API Management is Microsoft's fully managed API gateway and lifecycle management platform. It sits between your API consumers and your backend services, acting as a secure front door for API traffic. Rather than having multiple applications connect directly to backend systems, requests are routed through APIM where security policies, authentication, rate limits, logging, monitoring, and governance controls can be applied consistently.
For organizations investing in AI, APIM is becoming a critical component of production architectures. It allows teams to centralize access to Azure AI Foundry models, Azure OpenAI deployments, custom AI services, and internal APIs while maintaining visibility and control over who is using the service and how often.
