In the evolving landscape of cloud providers and microservices, understanding the roles of load balancers and API gateways is crucial for making informed architectural decisions that enhance product robustness while minimizing infrastructure costs. Load balancers are used to distribute incoming requests across multiple containers or servers, offering benefits like resiliency, security, and SSL termination, thus enabling horizontal scaling. Conversely, API gateways have become essential in microservices architecture by routing URL paths to various services, centralizing functions like authentication, authorization, and rate-limiting, which simplifies the management of multiple services. Despite their distinct functions, combining load balancers and API gateways can introduce complexity, such as increased latency and configuration challenges. To address these complexities, Kubernetes introduces the concept of Ingress, which routes external HTTP(S) traffic to services within a cluster, potentially simplifying infrastructure by integrating the routing capabilities of both load balancers and API gateways. Choosing the appropriate Ingress device requires a focus on ease of setup and the necessary features for current needs without overengineering.
