Regions, zones, and edge locations
On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
choose geography for latency, resilience, and data residency.
Planned topics
- A region is a geographic area; an availability zone (AZ) is an isolated data center group inside it; edge locations cache content near users.
- Spreading across AZs protects against a data center failure; spreading across regions protects against a regional one, at higher cost.
- Pick the region by user location, data-residency law, service availability, and price (verify before recording).
- Data residency decides where personal data may be stored and processed, not only where users are.
- Latency to the nearest region matters less once a content delivery network (CDN) serves static content.
Draft outline details
Demonstration
a map sketch: stores in one country, one primary region with three zones, a CDN at the edge, and a second region greyed out as the DR option.
Check your understanding
What does a second AZ protect against?
Show answer
Failure of one data center group, not a whole region.
