The presentation discusses the reserves and optimization strategies for bare metal servers in a Kubernetes cluster to minimize energy consumption and costs.
- There are three types of reserves: scale out reserves for future growth, geo-resident density reserves, and peak performance reserves.
- Automation is key to quickly re-enabling hardware and minimizing energy consumption.
- Immutable infrastructure and active-active data centers help with geo-redundancy reserves.
- Transparency and buy-in from management is important for balancing potential cost savings and risks.
- The presentation emphasizes the importance of measuring and quantifying energy consumption to make informed decisions about optimization strategies.
