Question 8
Your organization is planning to design a cloud solution architecture for a new application that will have significant variations in demand and should be cost-effective. As a cloud architect, what strategy would you propose for this scenario?
-
A
Deploy the application on App Engine standard environment.
-
B
Use preemptible VMs for all parts of the application.
-
C
Use sole-tenant nodes for hosting the application.
-
D
Use Compute Engine instances with fixed resources, manually adding or removing instances as demand fluctuates.
Reveal correct answer
Correct answer: A
A.
App Engine standard environment is a fully managed serverless platform that automatically scales your app up and down while balancing the load. This matches the requirements of significant variations in demand and cost-effectiveness.
B.
While preemptible VMs can be cost-effective, they are not guaranteed to be available when needed, and they can be terminated at any time, making them unsuitable for a critical application that needs to be highly available.
C.
Sole-tenant nodes are physical Compute Engine servers dedicated to hosting VM instances for your specific project. While they provide isolation, they are not cost-effective for applications with fluctuating demand since you are paying for the entire node regardless of usage.
D.
This strategy does not provide automatic scaling in response to demand and would require significant overhead in monitoring and manual intervention.
