Episode notes
Migrated From Self-Managed To EKS
- Target moved from self-managed clusters (COPS) to EKS when the Sydney region gained support.
- They immediately benefited from managed control plane reliability and faster feature improvements from AWS.
Adopt Bottlerocket For Leaner Hosts
- Switch to Bottlerocket for worker nodes to reduce host attack surface and maintenance overhead.
- Expect fewer host vulnerabilities, faster performance, and lower compute costs when you replace general-purpose AMIs.
Minimal OS Design Improves Performance
- Bottlerocket's immutable, minimal design removes unnecessary packages and SSH, shrinking the OS attack surface.
- That lean design correlated with significant latency improvements and lower compute needs at Target.
