How do I choose the right cloud region for my business?
Choose the region by working through three questions in order: where must your data legally be stored, where are most of your users, and where are your other systems. The first question is a hard constraint, the second affects latency, and the third affects cost and complexity. When they point in different directions, legal requirements win.
Region choice is easier to get right at the start than to change later. Moving a production database or a Kubernetes cluster between regions is a project in its own right, so it is worth settling before you build.
| Market | Regions mentioned on our pages | Main regulatory context |
|---|---|---|
| USA | AWS us-east-1, us-west-2 | SOC 2 expectations, state privacy laws such as CCPA |
| United Kingdom | AWS eu-west-2 (London) | UK GDPR |
| Europe | AWS eu-central-1 (Frankfurt), eu-west-3 (Paris) | GDPR, DORA for financial entities |
| UAE | AWS me-central-1 (UAE) | UAE data protection law and localisation rules |
| Saudi Arabia | See the Saudi Arabia page | Saudi data protection and localisation requirements |
What is the difference between data residency and data sovereignty?
Data residency is about where data is physically stored. Data sovereignty is about which country's laws apply to it, which can depend on who controls the data and the provider, not only on where it sits. Keeping data in a regional data centre usually satisfies a residency requirement, but it may not settle every sovereignty question.
For this reason, residency should be treated as an engineering requirement and sovereignty as a legal question. We can design the architecture so that data stays in the chosen region, including backups, logs and replicas. Your legal adviser should confirm whether that is sufficient for your obligations.
Why do backups and logs matter for residency?
A common mistake is to place the primary database in the right region while backups, monitoring data or logs flow elsewhere. Those secondary copies often contain personal data too. A residency design needs to account for every place data lands, including cross-region replication, disaster recovery copies, and third party tools that receive telemetry.
Disaster recovery adds a further decision. A second region improves resilience, but if the rules restrict where data can go, the recovery region must also be acceptable. Our backup and disaster recovery service covers how to plan this.
- Primary data stores and their read replicas.
- Backups and snapshots, including cross-region copies.
- Logs, metrics and traces that may contain identifiers.
- Container registries, artefact stores and CI runners.
How does time zone coverage work across regions?
Working across the USA, the UK, Europe and the Middle East means normal working hours overlap only partly. The UK and Europe overlap well with both the Middle East and the US East Coast in different parts of the day. For planned work, we agree meeting times and hand-off points in writing at the start of an engagement.
For out-of-hours incident cover, coverage depends on the engagement. If you need on-call support, our observability and on-call setup package and managed DevOps plans describe what is included, and you should confirm the hours with us before relying on them.
What happens if I operate in more than one region?
Multi-region operation adds complexity, so it is worth asking whether you truly need it. Some businesses run a single primary region with a recovery region. Others need separate regional deployments so that each jurisdiction's data stays local. These are different architectures with different costs.
Infrastructure as code makes multi-region work far more manageable, because each region is created from the same reviewed definitions. A landing zone gives you consistent accounts, networking and guardrails to build on, which is why we often start there.
