VIRTUALIZATION
• The creation of a virtual rather than actual.• Version of something such as a hardware, platform,
OS, storage device. • Types:
Platform virtualization Resource virtualization

FLAVORS
• Software as a Service (Saas)• Platforms as a Service (Paas)• Infrastructure as a Service (Iaas)

Software as a service (Saas)
• From end user’s point of view.• Apps are located in the cloud.• Software experiences are delivered through the
Internet.
04/09/2023 Cloud Computing 11
Platform as a Service (PaaS)
• From developer’s point of view.• i.e. cloud users.• Provides a computing platform and a solution stack
as a service.
04/09/2023 Cloud Computing 12
Infrastructure as a Service (IaaS)
• Cloud providers build datacenters.
Power, scale, hardware, networking, storage, distributed systems.
• Datacenter as a service.

CLOUD STORAGE
• In cloud data storage user sees a virtual server.• The place doesn't exist in reality.• Creates one or more duplicate data.• Actual storage location may differ.• E.g.: cloud services
Amazon Microsoft Google
