Question

A company runs a container application by using Amazon Elastic Kubernetes Service (Amazon EKS). The application includes microservices that manage customers and place orders. The company needs to route incoming requests to the appropriate microservices. Which solution will meet this requirement MOST cost-effectively?

Accepted Answer

**Option B: Use the AWS Load Balancer Controller to provision an Application Load Balancer (ALB)**

**Requirement 1: Route incoming requests to appropriate microservices**
- ALB operates at Layer 7 (HTTP/HTTPS) and supports **path-based routing** and **host-based routing**. For example:
  - `/customers/*` → Customer microservice pods
  - `/orders/*` → Order microservice pods
- The AWS Load Balancer Controller watches for Kubernetes **Ingress** resources and automatically provisions and configures an ALB with the correct target groups and routing rules.
- Each microservice is registered as a separate target group, and ALB routes based on Ingress rules.

**Requirement 2: MOST cost-effectively**
- A single ALB can handle routing to multiple microservices using Ingress rules. You pay for **one
