Edge Stack is a robust, production-ready API Gateway that provides high availability and redundancy to prevent Single Points of Failure (SPOF). It's built on Envoy as a Kubernetes deployment, ensuring scalability, high availability, and persistence. Edge Stack offers several advantages, including Kubernetes-native availability and efficiency, horizontal and vertical pod scaling, built-in high-performance rate limiting, circuit breakers, configurable timeouts, and fast reconfiguration. The platform also provides observability features aligned with the Four Golden Signals on monitoring, making it easy to output data to monitoring tools like Prometheus. Multiple domains, gateways, regionalization, and multi-region deployment are redundancy strategies that can be employed to ensure business continuity and resilience. By implementing these safeguards, developers can prevent their API Gateway from becoming a point of failure in their microservices architecture.
