Reversed
This is a physical location in the world where we have multiple Availability Zones.
Each of these are designed to be completely isolated from the others. This achieves the greatest possible fault tolerance and stability
AWS Region
Availability Zones
These consist of
one or more discrete data centers, each with redundant power, networking, and connectivity, housed in separate facilities.
These offer you the ability to operate production applications
and databases that are more highly available, fault tolerant, and scalable than would be possible from a single data center.
Each of these is isolated, but each of these in a Region are connected through low-latency links. Each of these is designed as an independent failure
zone. This means that they are physically separated within a typical metropolitan region and are located in lower risk flood plains (specific flood zone categorization varies by AWS Region). In
addition to discrete uninterruptible power supply (UPS) and onsite backup generation facilities, data centers located in different
Availability Zones are designed to be supplied by independent substations
to reduce the risk of an event on the power grid impacting more than one Availability Zone. Availability Zones are all redundantly connected to multiple tier-1 transit providers.
