What is virtualization in cloud computing?

• Virtualization in cloud computing is the creation of a virtual version of a device or resource, allowing multiple virtual instances to run on a single physical machine.

• Virtualization in cloud computing is the process of physicalizing virtual resources.

• Virtualization in cloud computing involves the direct mapping of physical resources to virtual instances.

• Virtualization in cloud computing refers to the creation of a physical version of a virtual machine.

What are the key characteristics of cloud computing?

• Off-demand self-service, narrow network access, resource hoarding, slow elasticity, unmeasured service

• Limited access, individual service, slow elasticity, unmeasured service

• On-demand self-service, broad network access, resource pooling, rapid elasticity, measured service

• On-demand self-service, limited network access, resource segregation, slow elasticity, unmeasured service

What is the difference between scalability and elasticity in cloud computing?

• Scalability is about the system's ability to shrink, while elasticity is the ability to expand resources.

• Scalability refers to the ability to adjust resources manually, while elasticity is automatic resource adjustment.

• Scalability is about the system's capacity to handle growth, while elasticity is the ability to dynamically adjust resources based on demand.

• Scalability and elasticity are interchangeable terms in cloud computing.
