AWS torganizza l-infrastruttura globali tagħha f'Regions (postijiet ġeografiċi) u Availability Zones (data centers iżolati ġewwa reġjun). Il-fehim tagħhom huwa fundamentali għad-disinn ta' applikazzjonijiet li huma affidabbli (fault-tolerant) u performanti (latency baxxa).
Regions — postijiet ġeografiċi
A REGION is a geographic area with AWS infrastructure (e.g. us-east-1 Virginia,
eu-west-1 Ireland, ap-southeast-1 Singapore):
→ choose regions based on: proximity to USERS (lower latency), data RESIDENCY/
compliance (where data must legally reside), service availability, and cost
→ regions are isolated from each other (a region's issues don't affect others)
