A cloud architect must recommend an architecture approach for a new medical application that requires the lowest downtime possible. Which of the following is the best application deployment strategy given the high-availability requirement?
A.
Two different availability zones (per region) using an active-active topology in two different regions
B.
Four different availability zones using an active-passive topology in a single region
C.
Four different availability zones using an active-active topology in a single region
D.
Two different availability zones (per region) using an active-passive topology in two different regions
Answer: A. Two different availability zones (per region) using an active-active topology in two different regions
To achieve the lowest downtime possible, you want redundancy at both the availability zone (AZ) and regional levels, along with an active-active design. This way:
Each region uses multiple AZs for resilience within that region.
The application runs actively in two separate regions so if one region experiences a major outage, traffic can continue in the other region without incurring downtime associated with “failing over.”
