Cloud computing describes both a platform and a type of application. A cloud computing
platform dynamically provisions, configures, reconfigures, and deprovisions servers as needed. Cloud applications are applications that are extended to be accessible through the Internet and they use
large data centers and powerful servers that host Web applications and Web services.Cloud computing infrastructure accelerates and fosters the adoption of innovations. Cloud computing infrastructure allows enterprises to achieve more efficient use of their IT
hardware and software investments.
Definition:
A cloud is a pool of virtualized computer resources. A cloud can Host a variety of different workloads, Support redundant, self-recovering, highly scalable programming models , Allow workloads to be deployed and scaled-out fast and Monitor resource use in real time.
Benefits:
Helpls in breaking down the physical barriers in isolated systems. It provides an ultimately virtualized system, and it can can be a cost efficient model for delivering information services, reducing IT management task complexity.
Architecture
The cloud computing system consists of the data center, IBM® Tivoli® Provisioning Manager, IBM® Tivoli® Monitoring, IBM®
Websphere® Application Server, IBM® DB2®, and virtualization components.
The user interfaces to provision servers are:
-One interface provides basic screens for making provisioning requests.
-One interface is feature rich -- fully loaded with the WebSphere suite of products -- and
relatively more involved from a process perspective.
