Abstraction is a key concept in cloud computing because it allows users to focus on the applications and data that they need to access, without having to worry about the underlying infrastructure.
Here is a brief explanation of each option:
- Virtualization is the process of creating a virtual version of a physical resource, such as a computer or storage device. This allows multiple users to share the same physical resource, and it can also be used to create isolated environments for testing or development.
- Mobility pattern is a term used to describe the way in which users access and use applications and data. There are a number of different mobility patterns, including mobile, nomadic, and fixed.
