**The Basics (101)
**AWS Global Infrastructure
You will never be tested on numbers (e.g. number of regions/availability zones)
**
Region
**
-> Geographical (Brazil, Europe, Asia, etc)). Each region consists of two or more availability zones (AZ). It's not in the same phisical space (if a flooding occurs, other data center can still answer)
Availability zone -> Data center
North America Regions:
US East (Northern Virginia)
US East (Ohio) Region
US West (Oregon) Region
US West (Northern California) Region
AWS GovCloud (US-West Region)
Canada (Central)
Edge Locations -> CDN (content delivery network). They add new ones all the times, over 100 so far. There are many more Edge Locations than Regions.
