We use Spring Boot and gRPC on AWS ECS Fargate behind AWS Application Load Balancers. We wanted to allow the ALB to query Spring Actuator’s robust health checks.

It’s mostly a toy used for non-critical backups, so it was fun to tinker with. However, I’ve suffered disk losses multiple times despite […]

Our service location and load balancing method is currently a combination of DNS and AWS Network Load Balancers. We’ve been plagued […]
