What are regions?
How many regions are there?
Regions are independent geographic areas that consist of zones.
GCP has 25 Regions
What is Edge networking?
having compute and storage as close to the end-user to reduce latency and to save bandwidth
What are PoP’s?
Points of Presence - An intermediate location between a GCP Region and the end-user
Three types of PoP’s?
Edge PoP - A location where a user can quickly enter (ingress) the GCP Network for accelerated access to cloud resources
CDN PoP - A location to serve (egress) cached website, files, assets so they load very fast for the end-user
Cloud Media Edge - a location specialized for the delivery of media such as video content
What is a Zone?
Are data centers isolated from eachother?
How many zones would you run workloads in and why?
Do you choose your zones?
A Zone is a physical location made up of one or more datacenter. ( which contain hundreds of thousands of computers)
A region will generally contain 3 Zones
Datacenters within a region will be isolated from each other (so different buildings). But they will be close enough to provide low-latency.
Its common practice to run workloads in at least 3 Zones to ensure services remain available in case one or two datacenters fail. (High Availability)
Once you have chosen your Region, you will proceed to choose your Zone or Zones when launching cloud resources.
