Region Selection Economics
Balance price, latency, residency, and egress when picking regions.
Executive Summary & Quick Answer
The same virtual machine can cost twice as much - or half as much - depending only on its region. Region selection balances price, latency, data residency, and service availability.

Price spreads between regions are real
US and European flagship regions carry the deepest capacity and lowest base prices; emerging-market and remote regions add premiums of 10-40%. Comparing your candidate regions side by side takes minutes and compounds into permanent savings.
Latency sets the floor, not the ceiling
Users notice round trips above ~100 ms. Choose the cheapest region within acceptable latency of your users, not the closest region regardless of price.
Residency and compliance constraints
GDPR, sector rules, and corporate policy can pin workloads to specific jurisdictions. When residency forces a pricier continent, offset by moving batch, analytics, and staging workloads to cheaper regions.
Egress and inter-region traffic
Data transfer between regions - and out to the internet - can outweigh compute savings on chatty architectures. Co-locate tightly coupled systems; keep caches near users.
Key takeaways
- Identical instances vary widely in price between regions.
- Pick the cheapest region inside your latency and residency envelope.
- Model egress before splitting tiers across continents.
