Whats an AZ?
An Availability Zone is a single data center or a group of data centers within a Region
Define some characteristics about AZ? latency, distance.
located tens of miles apart from each other. But close enough for low latency when info requested and received between AZs.
distant enough to reduce the chance that multiple Availability Zones are affected.
Why run EC2s in multiple AZ?
best practice is to run applications across at least two Availability Zones in a Region
If 1 were to fail, your application would still be running in us-west-1b.
Planning for failure and deploying applications across multiple Availability Zones is an important part of building a ________________
resilient and highly available architecture.
