Quiz yourself on cloud computing basics

To grasp a technology, it's best to start with the basics. Take this brief cloud computing quiz to gauge your knowledge of providers, deployment models and other 101-level topics.

Cloud computing is a popular technology model in which a provider hosts IT resources and delivers them to users via a network connection.

Almost all cloud offerings provide self-service capabilities for end users, scalability to meet dynamic computing needs, resiliency to keep workloads running and pay-per-use pricing. Differences show up, however, in the numerous deployment models and services from which an enterprise can choose. This makes it important to first understand cloud computing basics to make informed adoption decisions.

Assess your knowledge of general cloud computing concepts with this brief quiz.

What aspect of cloud computing is most confusing for beginners?
I would say that the understanding that cloud is a new business model and not a technology model can require a change in discussion for several people. One other challenge is understanding that you do not simply move existing applications to the cloud (for example Lift & Shift) and that a move to cloud for existing applications should also ensure that they are properly architected or designed for cloud computing and the guaranteed need for failover.

When designing a cloud-based system, the system architect must be aware of the (a) of the cloud environment (usually described in the SLA/s), as they will have direct impact on the possible (a) of the system that is being designed.

It is also worth noting the (a) described in the cloud provider's SLA may not be exactly the (a) the cloud consumer will get because of several infrastructure issues, e.g., network issues and if the cloud provider SLA is providing only metrics obtained inside their own firewall infrastructure.

In this context, (a) is:

does anyone know the answer to that question?

I am a beginner, and for me it would be the security aspects.
