Cloud Computing Architecture Interview Questions and Answers

1
What is the use of defining cloud architecture?

Cloud architecture is a software application that uses on demand services and access pool of resources from the cloud. Cloud architecture act as a platform on which the applications are built. It provides the complete computing infrastructure and provides the resources only when it is required. It is used to elastically scale up or down the resources according to the job that is being performed.

Can you please explain the difference between vertical scale up and Horizontal scale out?

Vertical scale up provides more resources to a single computational unit, whereas horizontal scale out provides additional computational unit and run them in parallel.
Vertical scale up provides a provision to move a workload to other system that doesn’t have workload, whereas horizontal scale out split the workload among various computational units.
Vertical scale up doesn’t have a database partitioning concept, whereas horizontal scale out provides the database partitioning.

3
How does cloud architecture overcome the difficulties faced by traditional architecture?

Cloud architecture provide large pool of dynamic resources that can be accessed any time whenever there is a requirement, which is not being given by the traditional architecture. In traditional architecture it is not possible to dynamically associate a machine with the rising demand of infrastructure and the services. Cloud architecture provides scalable properties to meet the high demand of infrastructure and provide on-demand access to the user.

4
What are the three differences that separate out cloud architecture from the tradition one?

The three differences that make cloud architecture in demand are:

  1. Cloud architecture provides the hardware requirement according to the demand. It can run the processes when there is a requirement for it.
  2. Cloud architecture is capable of scaling the resources on demand. As, the demand rises it can provide infrastructure and the services to the users.
  3. Cloud architecture can manage and handle dynamic workloads without failure. It can recover a machine from failure and always keep the load to a particular machine to minimum.
