What is Cloud Computing???

Cloud Computing is the evolution and convergence ofmany seemingly independent computing trends :

• SaaS, PaaS, IaaS, XaaS• Utility Computing• Virtualization• SOA• Grid Computing• Distributed Computing• Data Center Automation

• Intenet Delivery• Commoditization

• Web 2.0• IT Outsourcing

Definition

• Outsourcing infrastructure to the ‘cloud’

• Renting virtual infrastructure

processing-power, storage etc.

• Traditional Data Center

Datacenter as a Service

Two Types of Clouds

• On-demand resources & services over a network at the scale of a data center

On-demand computing instances (IaaS)- Support many Web 2.0 applications/users

On-demand cloud services for large data cloud application (PaaS for large data clouds)

- Manage and compute with large data

Best-suited for Cloud Computing

• To your best knowledge, what two solutions are best- suited for a Cloud Computing environment?

Web Applications

Database Server

Application Server

Testing/Development

File/Print Server

Traditional IT

Other (Media/File/Raw Stroage, E-mail etc)

Changing Landscape of Data Center

Datacenter 1.0

• Generic machines stored together in a locked room• Mostly physical servers• Provision time-days• User did not have much control on what was in the server room• Very little or no mgmt tools• Data center admin role mostly menial

Datacenter 2.0

• Blade servers, VMs• Physical & virtual servers• Provision time down to hours• Self service provision-ing• Mgmt tools used extensively• Data center admin role more challenging

Datacenter 3.0

• Cloud based• Physical & virtual server and virtual resources• Provision time in minutes• Dynamic & transpar-ent provisioning• Mgmt tools come installed along with the hardware• Data center admin role much more sophisticated

Conclusions

• Don’t waste resources on building your own datacenters

• Consolidate & mi-grate

• Build or buy web applications

• Multitenant solutions are avail-able

• Virtualiaza-tion

• Pay-per-use
