Sustainable Caching: Low-Carbon Routing and Cache Node Selection (2026 Guide)
Hook: Sustainability is now a factor in caching decisions. In 2026, teams route traffic to lower-carbon cache nodes and measure the emissions impact of cache placement.
Principles
- Prioritize nodes with renewable energy mixes where possible.
- Balance emissions goals with latency and cost tradeoffs.
- Use batch-sensitive workloads to prefer low-carbon windows.
Implementation steps
- Obtain provider carbon metrics and map nodes to regions.
- Define latency bounds that still meet SLOs while preferring greener nodes.
- A/B test routing policies and measure real-user impact before broad rollout.
