AWS Region design
AWS Regions are comprised of multiple AZs for high availability, high scalability, and
high fault tolerance. Applications and data are replicated in real time and consistent
in the different AZs.
AWS Availability Zone (AZ)
A Region is a physical location in the world
where we have multiple Availability Zones.
Availability Zones consist of one or more discrete data
centers, each with redundant power, networking, and
connectivity, housed in separate facilities.

Case Study: Halodoc
“Before AWS, 20–30 percent of our time would be spent
ensuring that servers are responsive. By using AWS, we
simply deploy and maybe monitor for an hour and that’s
it.”
Abhilash Ramakrishna
Chief Technology Officer, Halodo
Halodoc aims to improve access to healthcare and medicine through its app,
and has 20,000 doctors and 1,000 pharmacies in its partner network
