Episode notes
Cost and Control of Own Hardware
- Running your own hardware can be much cheaper than cloud due to avoiding egress fees and taxes.
- It also gives more control and better performance, but requires careful capacity planning and tuning.
Kubernetes Over-Provisioning Waste
- 80% of containerized workloads are over-provisioned, leading to significant waste.
- This waste translates directly into paying more in cloud or infrastructure costs.
Avoid Full Load for Stability
- Avoid running systems at full load to meet strict SLAs and reduce tail latency.
- Overloaded Linux systems risk kernel OOM killer locking up and needing a power cycle, so reserve capacity for stability.
