The document discusses cloud computing and its benefits for businesses. It defines cloud computing as providing computing resources like servers, storage, and applications over the internet. The cloud delivers a flexible hosting environment that saves corporations money, time, and resources. It allows businesses to increase capacity or add capabilities without investing in new infrastructure. The document then discusses how cloud computing addresses fluctuating demand by providing infrastructure and tools on a pay-per-use basis. It also outlines the different types of cloud services including Software as a Service (SaaS), Infrastructure as a Service (IaaS), and Platform as a Service (PaaS). Finally, it discusses future trends like the growing adoption of hybrid cloud models that integrate public and private clouds.

2.  Simply put, cloud computing provides a variety of
computing resources , from servers and storage to
enterprise applications such as email, security,
backup/DR, voice, all delivered over the Internet.
 The Cloud delivers a hosting environment that is
immediate, flexible, scalable, secure, and available –
while saving corporations money, time and resources.
 What IT always needs: a way to increase capacity or
add capabilities on the fly without investing in new
infrastructure, training new personnel, or licensing
new software. Cloud computing encompasses any
subscription based or pay-per use service that, in real
time over the Internet, extends IT's existing
capabilities.

3. Acceptable Surplus Unacceptable Surplus & Deficit Utility Infrastructure
Model
>The Red portions in the
above figure shows the
unused infrastructure of
the company i.e the
Unused data / storage
etc. on which the company
has already invested but
get no returns as
it goes unused.
>At certain times the
company ‘s infrastructure
goes unused(green
portions)and at other times
they are exhausted and in
need of more(red portion).
>For such fluctuating
demands cloud computing
plays an important role
where you will be provided
infrastructure as per usage
and charged also as per
your usage.
>By using cloud
facilities, the companies
can use the
Infrastructre(developm
ent Platforms) and
soft wares, storage
space and other tools
based on the companies’
requirement. This saves
a lot on investments and
regulates pay-per-usage
WHY COMPANIES NEED CLOUD COMPUTING??

4. Cloud Flavors?
 Software As A Service
 SaaS is a software
delivery methodology
that provides licensed
multi-tenant access to
software and its
functions remotely as a
Web-based service.
 Usually billed based
on usage
 Usually multi tenant
environment
 Highly scalable
architecture
• Infrastructure As A
Service
• IaaS is the delivery
of technology
infrastructure as an
on demand scalable
service
– Usually billed
based on usage
– Usually multi
tenant virtualized
environment
– Can be coupled
with Managed
Services for OS
and application
support
• Platform As A Service
• PaaS provides all of the
facilities required to
support the complete life
cycle of building and
delivering web applications
and services entirely from
the Internet.
– Typically applications
must be developed with
a particular platform in
mind
– Multi tenant
environments
– Highly scalable multi
tier architecture

5. Deployment Models
Public cloud
• Public cloud (off-site and remote) describes cloud computing where
resources are dynamically provisioned on an on-demand, self-service
basis over the Internet, via web applications/web services, open API,
from a third-party provider who bills on a utility computing basis.
Private cloud
• A private cloud environment is often the first step for a corporation
prior to adopting a public cloud initiative. Corporations have discovered
the benefits of consolidating shared services on virtualized hardware
deployed from a primary datacenter to serve local and remote users.
Hybrid cloud
• A hybrid cloud environment consists of some portion of computing
resources on-site (on premise) and off-site (public cloud). By integrating
public cloud services, users can leverage cloud solutions for specific
functions that are too costly to maintain on-premise such as virtual
server disaster recovery, backups and test/development
environments.
Community cloud
• A community cloud is formed when several organizations with similar
requirements share common infrastructure. Costs are spread over
fewer users than a public cloud but more than a single tenant.

6. Interest Areas
 I would like to work on an internship in the area
of cloud computing as it’s the present and the
future for any sort of infrastructure
requirements and software licensing etc. It will
soon be an “All cloud usage” for all requirements
FUTURE of CLOUD
 In the next 5 years, it will be a “goodbye to
traditional infrastructures”
 There may not be a need of Hard drives in the
systems at all.
 Industry studies also reveal that by 2017 the
more than 55% of the companies will have hybrid
cloud
