ABSTRACT
Cloud computing is basically an Internet-based network made up of large numbers of
servers - mostly based on open standards, modular and inexpensive. Clouds contain
vast amounts of information and provide a variety of services to large numbers of
people. The benefits of cloud computing are Reduced Data Leakage, Decrease evidence
acquisition time, they eliminate or reduce service downtime, they Forensic readiness, they
Decrease evidence transfer time The main factor to be discussed is security of cloud
computing, which is a risk factor involved in major computing fields
CLOUDCOMPUTING
What is a Cloud computing?
Cloud computing is Internet- ("CLOUD-") based development and use of computer
technology ("COMPUTING")
Cloud computing is a general term for anything that involves delivering hosted services over the Internet.
It is used to describe both a platform and type of application.
Cloud computing also describes applications that are extended to be accessible through the
Internet.
These cloud applications use large data centers and powerful servers that host Web
applications and Web services.
Anyone with a suitable Internet connection and a standard browser can access a cloud
application.
User of the cloud only care about the service or information they are accessing - be it from their
PCs, mobile devices, or anything else connected to the Internet - not about the underlying details
of how the cloud works.”
History
The Cloud is a metaphor for the Internet, derived from its common depiction in network diagrams
(or more generally components which are managed by others) as a cloud outline.
The underlying concept dates back to 1960 when John McCarthy opined that "computation may
someday be organized as a public utility" (indeed it shares characteristics with service bureaus
which date back to the 1960s) and the term The Cloud was already in commercial use around
the turn of the 21st century. Cloud computing solutions had started to appear on the market,
though most of the focus at this time was on Software as a service.
2007 saw increased activity, including Goggle, IBM and a number of universities embarking on
a large scale cloud computing research project, around the time the term started gaining popularity
in the mainstream press. It was a hot topic by mid-2008 and numerous cloud computing events
had been scheduled.
WHAT IS DRIVING CLOUD COMPUTING?
The CLOUD COMPUTING is driving in two types of categories .They are as follows:
Customer perspective
Vendor perspective
Customer perspective:
In one word: economics
Faster, simpler, cheaper to use cloud computation.
No upfront capital required for servers and storage.
No ongoing for operational expenses for running datacenter.
Application can be run from anywhere.
Vendor perspective:
Easier for application vendors to reach new customers.
Lowest cost way of delivering and supporting applications.
Ability to use commodity server and storage hardware.
Ability to drive down data center operational cots.
Types of services:
These services are broadly divided into three categories:
Infrastructure-as-a-Service (IaaS)
Platform-as-a-Service (PaaS)
Software-as-a-Service (SaaS).
Infrastructure-as-a-Service (IaaS):
Infrastructure-as-a-Service(IaaS) like Amazon Web Services provides virtual servers with unique
IP addresses and blocks of storage on demand. Customers benefit from an API from which they
can control their servers. Because customers can pay for exactly the amount of service they use,
like for electricity or water, this service is also called utility computing.
Platform-as-a-Service (PaaS):
Platform-as-a-Service(PaaS) is a set of software and development tools hosted on the provider's
servers. Developers can create applications using the provider's APIs. Google Apps is one of the
most famous Platform-as-a-Service providers. Developers should take notice that there aren't any
interoperability standards (yet), so some providers may not allow you to take your application and
put it on another platform.
Software-as-a-Service (SaaS):
Software-as-a-Service (SaaS) is the broadest market. In this case the provider allows the
customer only to use its applications. The software interacts with the user through a user
interface. These applications can be anything from web based email, to applications like
Twitter or Last.fm.
Types by visibility:
Public cloud:
Public cloud or external cloud describes cloud computing in the traditional mainstream sense,
whereby resources are dynamically provisioned on a fine-grained, self-service basis over the
Internet, via web applications/web services, from an off-site third-party provider who
shares resources and bills on a fine-grained utility computing basis.
Hybrid cloud:
A hybrid cloud environment consisting of multiple internal and/or external providers] "will be
typical for most enterprises". A hybrid cloud can describe configuration combining a local device,
such as a Plug computer with cloud services. It can also describe configurations combining virtual
and physical, colocated assets—for example, a mostly virtualized environment that requires
physical servers, routers, or other hardware such as a network appliance acting as a firewall or
spam filter.
