4. DEFINITION OF CLOUD
• Cloud computing refers to applications and services that run on
a distributed network using virtualized resources and accessed
by common Internet protocols and networking standards.
• Cloud computing takes the technology, services and
applications that are similar to those on the Internet and turns
them into a self-service utility.

5. DEFINITION OF CLOUD
Cloud
Virtualization :
• Cloud Computing virtualizes
systems by pooling and sharing
resources.
• Systems and storage can be
provisioned as needed from a
centralized infrastructure .
Abstraction :
• Cloud Computing abstracts the details
of system implementation from users
and developers .
• Applications : run on physical systems
that aren’t specified .
• Data : is stored in locations that are
unknown.
• Administration of systems: is
outsourced to others .
7. IMPORTANCE OF CLOUD
• Cloud computing is about storing the files and
resources on a server and then accessing it from
anywhere in the world via Internet.
• The need for physical space and high energy
costs will – and already do – increase that cloud
computing is a global reality.
8. IMPORTANCE OF CLOUD
Cost Savings
There is a better use of
server resources, which,
once working together,
allow the full use of
memory, processing, disk
space, etc.
Speed
Everything in cloud
computing is connected and
allows immediate
interaction. Changes are
applied better use of time is
also felt.
Security
Computer is used to carry
out all the important work.
cloud computing is one of
the most secure ways to
store all of your businesses
lead and sales information.
9. IMPORTANCE OF CLOUD
Almost Unlimited Storage
In the cloud computing, you can opt for
the unlimited storage plans that do not
cost you much.
The amount that you pay to your cloud
service provider for the unlimited
storage is less than what you’d have to
pay to buy storage devices.
Access your Data Anywhere
No need for physical access to the
system where you saved the data. All
is saved in the cloud, and you can
access it from anywhere, anytime via
Internet.
10. EXAMPLE OF AMAZON WEB SERVICES
• Amazon Web Services has been the frontrunner in the cloud
computing race for years, and it doesn't seem to be slowing
down.
• AWS continues to make moves to keep its customers happy
and entice enterprise IT, and it has an array of cloud services
that gives customers loads of options to best fit their IT
environments.
• « Amazon Web Services continues to drink other IT titans'
milkshake in the cloud. »
• Other vendors, such as Oracle and Microsoft, continue to
work to compete and fight their way to the top.
• AWS made number one on the Top 10 cloud computing
providers list at SearchCloudComputing.com for 2010, 2011
and 2012.
12. CHARACTERISTICS OF CLOUD COMPUTING
• On-demand self-service: Users are able to provision cloud computing
resources without requiring human interaction, mostly done though a
web-based self-service portal (management console).
• Broad network access: Cloud computing resources are accessible over
the network, supporting heterogeneous client platforms such as mobile
devices and workstations.
• Resource pooling: Service multiple customers from the same physical
resources, by securely separating the resources on logical level.
• Rapid elasticity: Resources are provisioned and released on-demand
and/or automated based on triggers or parameters. This will make sure
your application will have exactly the capacity it needs at any point of
time.
• Measured service: Resource usage are monitored, measured, and
reported (billed) transparently based on utilization. In short, pay for use.
14. CLOUD SERVICE MODELS
self-service models for:
Accessing and
monitoring.
Managing remote
datacenter infrastructures
and Storage.
Networking, and
networking services (e.g.
firewalls).
With SaaS, it’s easy for
enterprises to streamline
their maintenance and
support, because
everything can be
managed by vendors:
applications, runtime, data,
middleware, OSes,
virtualization, servers,
storage and networking.
With this technology,
enterprise operations, or a
third-party provider, can:
Manage OSes,
virtualization, servers,
storage, networking, and
the PaaS software itself.
The user has the
possibility of creating, of
deploying on an
infrastructure his own
applications.
19. PRIVATE, PUBLIC, HYBRID & COMMUNITY
CLOUD
PUBLIC
• Allows systems and services to be easily accessible to the general public.
• Less secure because of its openness.
PRIVATE
• Allows systems and services to be accessible within an organization.
• It offers increased security because of its private nature .
HYBRID
• The Hybrid Cloud is mixture of public and private cloud.
• The critical activities are performed using private cloud while the non-critical activities are performed using public cloud .
• Bridge incompatible clouds and traditional on-premises environments to operate fluidly as one.
COMMUNITY
• Allows systems and services to be accessible by group of organizations.
• Connect and collaborate with customers, partners, and employees.
• May be externally or internally hosted by one of the organizations sharing it.
20. PRIVATE, PUBLIC, HYBRID & COMMUNITY
CLOUD
Public Cloud: The customer has no visibility and control over where the
computing infrastructure is hosted. The computing infrastructure is shared
between any organizations.
21. PRIVATE, PUBLIC, HYBRID & COMMUNITY
CLOUD
Private Cloud: Private clouds can be expensive with modest economies of
scale. This is usually not an option for the average Small-to-Medium sized
business and is most typically put to use by large enterprises.
22. PRIVATE, PUBLIC, HYBRID & COMMUNITY
CLOUD
Hybrid Cloud:
• Allows users to scale computing requirements beyond the private cloud
and into the public cloud, a capability called cloud bursting.
• The goal of hybrid cloud is to create a unified, automated, scalable
environment that takes advantage of all that a public cloud
infrastructure can provide while still maintaining control over mission-
critical data.
24. ADVANTAGES
Economies of Scale: Lower variable
expenses that companies can achieve
themselves.
10’ s of millions of
dollars saved with first
12 apps migrated to
AWS
Saved 34 millions
dollars on SmartHub
applications
50% reduction in
analytics costs
26. ADVANTAGES
Speed & Agility: Infrastructures are provided in minutes
not in weeks or months. Quick respond to business needs
through high-capacity remote servers.
We can double the
server’s capacity in
20 seconds.
We reduced application
deployment’s time
from 2 weeks to 3 days.
Time to deploy went
from weeks to hours
27. ADVANTAGES
Focus on business: Allows companies to devote their
resources and mindshare to the core business.
Reduced development
and test environment
costs.
“We have a 5 person
operations team’’
Export operational data
to Amazon Redshift for
analytics.
2 times faster quieries at
½ the cost
28. ADVANTAGES
•Expand firm’s global
presence
SoftLayer has points of
presence (POPs). Each of
these data centers is
connected through high
speed fiber allowing
companies to coordinate
their global infrastructure.
Increased collaboration
Teams can access, edit and
share documents anytime,
from anywhere, they’re
able to do more together,
and do it better.
Cloud-based workflow and
file sharing apps give them
full visibility of their
collaborations.
Environmentally friendly
While the above points
spell out the benefits of
cloud computing for
your business, moving to
the cloud isn’t an
entirely selfish act. The
environment gets a little
love too.
29. DOWNSIDE
Prone to Attack
Storing information in the
cloud could make
companies vulnerable to
external hack attacks and
threats. Nothing on the
Internet is completely
secure and hence, there is
always the lurking
possibility of stealth of
sensitive data.
Performance on shared
infrastructure can be
inconsistent:
It’s a given that when
companies share
infrastructure with others,
they might be impacted by
noisy neighbors.
Cloud computing may not be
the right fit for all workloads:
Not all workloads are ready
for the cloud. Some workloads
have very specific
performance and security
requirements. Companies
need to evaluate their
workloads carefully to
determine whether they are
appropriate for the cloud.
30. DOWNSIDE
The legal framework
It is not clear where data are
stored. In addition, there is no
physical access to these data.
The cost of cloud
The costs of transfers must
also be considered when
companies are migrating their
data from cloud to cloud.
The collaborators’ productivity
Companies have to make sure
that collaborators understand
that moving to cloud
technology is not outsourcing or
a way to cut jobs, but rather an
opportunity.
32. EFFECTS OF CLOUD COMPUTING
ON IT JOBS
The authors argue that digital innovation has
“changed how the economic pie is distributed, and here
the news is not good for the median worker. As
technology races ahead, it can leave many people behind.
Workers whose skills have been mastered by computers
have less to offer the job market, and see their wages and
prospects shrink.”
33. EFFECTS OF CLOUD COMPUTING
ON IT JOBS
BusinessAnalysts in IT
User requirements & cloud-
based vendors must still be
selected, and applications must
still be integrated into business
processes.
IT Project Managers
More systems can be
implemented with less
internal IT resources.
Security Specialists
Increased cloud vendors means
more openings through company
firewalls and potentially the need
for manual procedures to manage
user access to cloud-based
applications.
