Effective CISSP Questions

Your organization is developing a microservices-based application. As a DevOps team member in charge of maintenance and operations, which of the following minimizes your workload the most? (Wentz QOTD)
A. Containerization
B. Serverless computing
C. Platform as a Service (PaaS)
D. Container orchestrator, such as K8S, Swarm, or Mesos

Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.

My suggested answer is B. Serverless computing.

Wentz’s book, The Effective CISSP: Security and Risk Management, helps CISSP and CISM aspirants build a solid conceptual security model. It is a tutorial for information security and a supplement to the official study guides for the CISSP and CISM exams and an informative reference for security professionals.

“Serverless computing is a cloud computing execution model in which the cloud provider allocates machine resources on demand, taking care of the servers on behalf of their customers.” (Wikipedia)

Platform as a Service (PaaS) is a good answer but not the test. Serverless computing is the best solution to minimize the workload of maintenance and operations because it’s a “pay as you use” model and you don’t have to deal with issues such as deployment, maintenance, scalability, elasticity, security, etc. Serverless computing sometimes is also known as Function as a Service (FaaS). FaaS customers who subscribe to the service may not know how it is implemented, e.g., containers, virtual machines, or bare metals.
