Simple arithmetic fails to capture the complex interplay between latency and cost in multi-region cloud deployments. The author proposes a framework that starts with decomposing the latency budget to inform infrastructure choices, selecting deployment patterns based on consistency and traffic profiles, and optimizing existing setups before adding regions. A phased strategy demonstrated that intelligent routing alone reduced latency by 35%, eventually bringing it under 60ms after introducing a new region.
- Decompose your total latency budget to guide infrastructure decisions rather than relying on simple cost math.
- Select deployment patterns based on strict consistency requirements and specific traffic profiles.
- Optimize routing and existing topology before committing to the expense of new regions.
- Phased approaches can yield significant latency gains (35%) through routing improvements alone.
