How a small team moved from single-region risk to a simple active/passive multi-region setup without doubling complexity.
Multi-region can easily become a science project. This is what worked for a five-person platform team supporting a SaaS product.
We began with everything in one AWS region: RDS, EKS, S3, and a shared VPC.
Instead of cloning the entire stack, we:

Concrete systemd unit patterns that reduced flakiness: restart policies, resource limits, and structured logs.
