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.

SAVING IT INVESTMENT AND COST

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 placethe 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.

CLOUD SERVICE MODELS

Infrastructure as a Service (IaaS)Platform as a Service (PaaS)Software as a Service (SaaS)

INFRASTRUCTURE AS A SERVICE (IAAS)

User can get dynamic infrastructure facility(CPU, Memory, and Network Bandwidth) by the provider in virtualized form.

Amzon is the pioneer of IaaS. Other leading providers are Rackspace,Windows Azure,VirtuStream,, GoGrid, Joyent, Rightscale , NetMagic  and InstaCompute.

PLATFORM AS A SERVICE (PAAS)

Service Provider provide cloud environment for development and deployment software.

In this environment Application developer can do development to testing without buying complex hardware or can avoiding preparing and manage complex environment.

With some PaaS offers, the underlying compute and storage resources scale automatically to match application demand

SOFTWARE AS A SERVICE

Cloud providers Prepare software deployment environment and user can host application software.

Cloud provider Maintained and managed software and infrastructure backup, security or infrastructural maintenance.

Project Management: DeskAway , Zoho Mail, Chat, Docs, Project, Sheet, Writer etc.CRM apps Impel CRM, Salesforce.com, and Microsoft Dynamics.Cloud based Storage Drop box, Skydive (windows live), Amazon S3, Google Docs, Box.net, Mozy.

DEPLOYMENT MODELS

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

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

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.

Business Opportunities as SaaS Moves

Forrester Research predicts that SaaS market will grow by 25 percent this year, to $59 billion, and reach $75 billion in 2014.

Bureau of Labor Statistics:27.9 million small companies in the U.S. those with fewer than 100 employees – had to settle for expensive and poorly scaled-down versions of vendors’ enterprise solution and there are just 18,500 companies with 500 employees or more.

Gartner revealed that “77 percent of companies were expecting to invest in SaaS at the beginning of 2013”
