2. INTRODUCTION
Cloud computing is a marketing term for technology
End - user do not require any knowledge regarding
system
Users can access and use facilities through a web
browser
3. What is Cloud Computing?
Cloud computing is used to describe a variety
of different types of computing concepts that
involve a large number of computers
connected through a real-time
communication network
cloud computing is the delivery
of computing as a service rather than
a product
4. What is Cloud Computing?
Utility computing
Platform
Cloud
8. Service Models
1
Infrastructure as
a Service (IaaS)
In this architecture
you're buying
access to raw
computing
hardware over the
Net, such as servers
or storage.
2
Software as a
Service (SaaS)
In this architecture
you use a complete
application
running on
someone else's
system
3
Platform as a
Service (PaaS)
In this you develop
applications using
Web-based tools
so they run on
systems software
and hardware
provided by
another company.
14. Advantages
Can be less expensive compared to buying
software and hardware
Can be used from any computer or device
with an Internet connection
The device does not need as large of an
internal storage system
Compatible with most computers and
operating systems
Updates occur across the service
17. CONCLUSION
• CLOUD COMPUTING IS THE FASTEST
GROWING PART OF IT
• TREMENDOUS BENEFITS TO CUSTOMERS OF
ALL SIZE
• CLOUD SERVICES ARE SIMPLER TO AQUIRE
• PUBLIC AND PRIVATE CLOUDS MAY BE USED
IN COMBINATION
Take the poll
Have you used the cloud
For one, two, three, or more of these services
ScalabilityInfrastructure capacity allows for traffic spikes and minimizes delays.
ResiliencyCloud providers have mirrored solutions to minimize downtime in the event of a disaster. This type of resiliency can give businesses the sustainability they need during unanticipated events.
Homogeneity: No matter which cloud provider and architecture an organization uses, an open cloud will make it easy for them to work with other groups, even if those other groups choose different providers and architectures.
On-demand self-service. A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service’s provider.
Broad network access. Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling. Multi-tenant model.. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing, memory, network bandwidth, and virtual machines.
Rapid elasticity. Capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured Service. Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts).
