+You can check out the AWS infrastructurnd regions here: [https://aws.amazon.com/about-aws/global-infrastructure/regions_az/](https://aws.amazon.com/about-aws/global-infrastructure/regions_az/)
+
+It's a global infrastructure, meaning we can deploy apps to be global
+
+## Regions
+
+Regions have names, e.g us-east-1
+
+A region is a cluster of data centres
+
+Most services are region scoped.
+
+Some factors in choosing regions could be:
+
+- Compliance
+- Latency
+- Service availability (some regions don't have certain services)
+
+Each region has 'zones', which are separate data centres from each other and are isolated from disasters.
+
+Not all services are available in all regions, see here: [https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/?p=ngi&loc=4](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/?p=ngi&loc=4)
