Creating an API gateway with a YARP reverse proxy and a custom load-balancing policy
In this recipe, we will build a custom API gateway using YARP. We will also create a custom load-balancing policy. Instead of ordinary pre-built load balancing, we will get the geolocation of the incoming request and redirect to the appropriate API based on the clients’ region. This API gateway setup is just one of the many ways YARP can be used to handle traffic efficiently, with flexible routing and load-balancing options.
You can use this recipe as a starting point for many practical purposes, such as gradually migrating a monolithic API to a more decentralized structure with independent services. With YARP, you gain fine-grained control over routing, enabling smoother transitions between legacy and modernized services, centralizing authentication, or even dynamically managing rate limiting and security policies within the gateway itself.
