An organization has been providing web services within their private cloud. The web services, deployed through a service catalog, depend on a database resource in the private cloud.

The organization decided to make these web services availability globally by using a public cloud provider.

However, once of the web services were deployed into the public cloud, users started complaining about poor performance.

Which solution would most likely improve performance of the web services.
A . Balance the load globally across multiple instances of the database
B . Re-architect the web-service to be deployed as a month coupled
C . Re-architect the web-service to be loosely coupled with the database
D . Balance the load globally across multiple instances of the web service.

Answer: D

Explanation:

Because things fail, it is important for cloud architects to design with the assumption that the underlying microservices infrastructure can and will fail.

However, when appropriately designed, nothing will really fail. The goal is applications that continue to function―even if the underlying physical hardware fails or is removed or replaced. One way to accomplish this goal is to avoid “single points of failure.” For example, having a distributed architecture supporting multiple instances, allows the infrastructure to reorganize service workloads as required .
