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.

5. WHAT IS CLOUD COMPUTING?
To access someone else's
software running on someone
else's hardware in someone
else's data center using the
internet.
An Organization can get service
as rental basis from service
provider (IBM ,Microsoft, Amazon,
Google, Virtu Stream ).
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.

8. Cloud Computing Characteristics
Pay as You use
Virtualization Device independence
Advanced Security
Unlimited Storage
Massive Scalability flexibility of Computing
Always on!, Anywhere
Essential Characteristics:
Resource Pooling
Network Access Rapid Elasticity
Measured Service
On Demand Self-Service
Common Characteristics:
10. INFRASTRUCTURE AS A SERVICE (IAAS)
(CPU, Memory, and Network Bandwidth)
Amzon is the pioneer of IaaS. Other leading
providers are Rackspace,Windows
Azure,VirtuStream,, GoGrid, Joyent,
Rightscale , NetMagic and InstaCompute.
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

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

companies with 500 employees or more.
Gartner revealed that “77 percent of companies
were expecting to invest in SaaS at the beginning of
2013”
22. WHAT IS WINDOWS AZURE?
Public Cloud platform
Build,
Deploy and
Manage applications
build applications
using any language, tool or framework
applications that use this data running on-premises
massively scalable applications
with lots and lots of users
