The correct answer is B. “Loose coupling” and D. “Remove single points of failure”.

Explanation:

Loose coupling is when you break systems down into smaller components that are loosely coupled together. This reduces interdependencies between systems components. This is achieved in the cloud using messages buses, notification and messaging services.

Removing single points of failure ensures fault tolerance and high availability. This is easily achieved in the cloud as the architecture and features of the cloud support the implementation of highly available and fault tolerant systems.

A. “Minimize platform design” is incorrect. This is not an operational advantage for workloads in the cloud.

C. “Customized hardware” is incorrect. You cannot customize hardware in the cloud.

E. “Minimum viable product” is incorrect. This is not an operational advantage for workloads in the cloud.
