This document discusses traditional server concepts and their limitations including single points of failure, maintenance issues, and costs. It then introduces cloud computing as an alternative that offers advantages like reduced costs, improved scalability, flexibility and reliability through virtualization, resource pooling and other techniques. The key cloud service models - Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) - are explained along with common deployment models. Characteristics of cloud computing and examples of cloud platforms like Windows Azure are also summarized.

- 2. THE TRADITIONAL SERVER CONCEPT In an organization there are many more server resides according to their functionality i.e Active directory Server , Application Server ,Database server ,Mail server ,File server and so on … Many types of risk involved there Such as Power failure, Hardware failure, Maintainability problems and Natural disaster. To avoid fault tolerance many types of initiative has to take like as clustering, mirroring, replication and so on… Application software requires more resources and times.

- 7. Hardware virtualization or platform virtualization refers to the creation of a virtual machine that acts like a real computer with an operating system. Software executed on these virtual machines is separated from the hardware resources. In hardware virtualization, the host machine is the actual machine on which the virtualization takes place the guest machine is the virtual machine. The software or firmware that creates a virtual machine on the host hardware is called a hypervisor or Virtual Machine Manager. VIRTUALIZATION

- 12. SOFTWARE AS A SERVICE
- 14. PRIVATE CLOUD Private Cloud solely use for a single organization to enable their IT infrastructure to more capable of quickly adapting to continually evolving business needs and requirements Optimizes the use of computing resources Ensures security potential risk managed internally or by a third-party Risk reduction from natural disaster User Group Research organization Corporate house Tools CloudStack
- 15. PUBLIC CLOUD A public cloud is one in which a service provider makes resources, such as applications and storage, available to the general public over the Internet Public clouds offer greater elasticity Inexpensive Setup Pay For What You Use User Group Corporate organization need state of the earth Tools Windows Azure, Google Apps
- 16. HYBRID CLOUD Hybrid cloud is an environment where the private and public services are used together to create value. Application deployed in public cloud platform but Keep data into a private cloud SaaS applications where data moves between private cloud or data center User Group Corporate organization need state of the earth Tools Windows Azure, Google Apps

- 18. Software as a Service(SaaS) Software as a Service (SaaS) makes use of a cloud computing infrastructure to deliver one application to many users, regardless of their location, rather than the traditional model of one application per desktop. 1. SaaS (Software as a Service) is low cost 2. Less Hardware Requirement 3. Capital expense to operational expense. 4. Reduce IT infrastructure Cost 5. Minimize maintenance cost 6. Reduce energy consumption
- 19. single-Tenant architecture user use dedicated instance of application software hosting on a server and database not shared. SAP is the company which provides service following the single tenant architecture. Multi-tenant architecture, multiple companies’ use same instance of application software. It is hosted in a server and data are kept in same server and data are separated by simple partition that prevents data migration. Salesforce.com is the successful SaaS provider having the multi-tenant architecture. SaaS Architecture :Single tenant vs. Multi- tenent
