Cloud computing allows on-demand access to configurable computing resources like networks, servers, storage, and applications via the internet. It provides low-cost IT infrastructure through a pay-as-you-go pricing model. Cloud computing resources are pooled and provisioned rapidly with minimal management effort. Key characteristics include on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. Cloud services can be deployed via public, private, community, or hybrid cloud models.

1. CLOUD COMPUTING

2. CLOUD COMPUTING
 Cloud computing means on demand delivery of IT resources via
the internet with pay-as-you-go pricing. It provides a solution of IT
infrastructure in low cost.
 Cloud computing is a model for enabling ubiquitous, convenient,
on-demand network access to a shared pool of configurable
computing resources (e.g., networks, servers, storage, applications,
and services) that can be rapidly provisioned and released with
minimal management effort or service provider interaction.

3. HYPERVISOR
• Hypervisor is a form of virtualization
software used in Cloud hosting to divide and
allocate the resources on various pieces of
hardware. The program which provide
partitioning, isolation or abstraction is called
virtualization hypervisor.
• Hypervisor is a hardware virtualization
technique that allows multiple guest
operating systems (OS) to run on a single
host system at the same time.

4. Types of Hypervisor –
• TYPE-1 Hypervisor:
Hypervisors run directly on the
system hardware – A “bare metal”
embedded hypervisor.
• TYPE-2 Hypervisor:
Hypervisors run on a host
operating system that provides
virtualization services, such as I/O
device support and memory
management.
