Region: collection of AZ geographically closely located (usually same city) so that worldwide customer base can take advantage of low latency connections; regions also allow compliance with with regulations, laws and governance relating data storage. (currently 26+)

Availability Zone : essentially physical data centers; 2 or more in each region, isolated from each other using separate power and network connectivity.

CloudFront: is a CDN, to get content closer to users

Edge location: AWS sites deployed in major cities/ highly populated areas. Not used for deployment our own infrastructure, but used by many services like CloudFront and Lambda@Edge to cache and reduce latency.

Regional Edge Cache: AWS sites located between Cloudfront Origin servers and Edge Location; they have a larger cache than individual Edge location and lower latency than Cloudfront.Cloudfront and Edge Locations

AWS Outposts: with outpost you can run some AWS services on dedicated hardware within your on-prem data centers

AWS Local Zones: for ultra low latency applications (live video, MRL, AR/VR)

AWS Wavelength Zones: similar to LocalZone but for 5G devices (single digit ms latency)

VPC (Virtual Private Cloud): a logically isolated portion of AWS cloud within a region

Private and Public subnets: a range of IP addresses in the VPC where we can place groups of isolated resources
