The concept of cloud computing has evolve from cluster, grid, and utility computing.
Cluster and grid computing leverage the use of many computers in
parallel to solve problems of any size.
A cloud is a pool of virtualized computer resources.
A cloud can host a variety of different workloads
, including batch-style backend jobs and interactive and user-facing applications.
The concept of cloud computing has evolve from cluster, grid, and utility computing.
Cluster and grid computing leverage the use of
many computers in parallel to solve problems of any size.
Utility and Software as a Service(SaaS) provide computing resources as a
service with the notion of pay per use.
Cloud computing leverages dynamic resources to deliver large numbers of
Cloud computing is a high-throughput computing(HTC) paradigm whereby the
infrastructure provides the services through a large data center or server farms.
The cloud computing model enables users to share access to resources from anywhere
at any time through their connected devices.
The cloud will free users to focus on user application development and create
business value by outsourcing job execution to cloud providers.
In this scenario, the computations (programs) are sent to where the data is
located, rather than copying the date to millions of desktops as in the traditional approach.
Cloud computing avoids large data movement, resulting in much better network bandwidth utilization.
Furthermore, machine virtualization has enhanced resource utilization, increased
application flexibility, and
reduced the total cost of using virtualized data-center resources.
The cloud offers significant benefit to IT companies by freeing them from the low-level
task of setting up the hardware (servers) and managing the system software.
