Choosing a data centre location used to be an afterthought. Today it is a decision with performance, legal and business consequences.
Latency: be near your users
Data travels through fibre at a large fraction of the speed of light, but distance still adds up. A round trip across a continent adds tens of milliseconds, and a web page needs many round trips. For interactive applications, APIs and anything real-time, put servers close to the people who use them. A CDN can bring static content closer, but dynamic requests still go back to the origin.
Law and regulation: know where your data is
Data protection laws, sector regulators and customer contracts may require that certain data stays in a specific country, or may restrict transfers abroad. Banks, payment companies, healthcare and government bodies are especially likely to face such rules. Before choosing a location, ask:
- Which laws apply to the data you will store?
- Do your regulators or customers require local hosting?
- Who could legally demand access to data in that country?
Resilience: do not put everything in one place
- A second location protects against regional problems: power, network, natural events, political or legal disruption.
- Keep backups in a different location from production.
- For critical services, consider a standby environment in another region with tested failover.
Practical factors
- Network quality and connectivity to your users' networks.
- Power and cooling resilience of the facility.
- Support availability in your time zone and language.
- Costs, which vary by region.
A sensible pattern
Many organisations run their main systems close to their customers or where regulation requires, keep backups in a second region, and use a CDN for global static content.
