Why is cloud computing necessary?

1. THE WHY OF A
CLOUD ????

2. What is cloud computing?
DEFINITION: Cloud computing is a technology that uses the
internet and central remote servers to maintain data and
applications. Cloud computing allows consumers and businesses
to use applications without installation and access their personal
files at any computer with internet access. Cloud computing
began as large-scale Internet service providers such as Google,
Amazon, and others built out their infrastructure
 A simple example of cloud computing is Yahoo email, Gmail, or
Hotmail etc.
 Cloud computing doesn’t require a software or a server to use
them. All a consumer would need is just an internet connection
and you can start sending emails.

3. * How Do We Save Money By Using Cloud
Computing Services?
*There are many ways a company saves money by using cloud services, but it
basically breaks down into a few simple categories:
1. Capital Expenditures (CapEx) - Every few years you purchase new servers,
storage, and other computer related equipment. The cost of procurement is
significant. Cloud computing eliminates much of this.
2. Physical Space - You have to put your equipment somewhere. That somewhere
costs per square foot.
3. Server back-ups and server maintenance.- All that equipment needed for the
maintenance are not required and updates in cloud happens automatically.
4. Electricity - All that equipment needs to be powered.
5. People - People with specialized skills are needed for managing and keeping
managing in premise solutions.

4. But is cloud computing
secure?

There are a number of security issues/concerns associated with
cloud computing but these issues fall into two broad categories:
 Security issues faced by cloud providers (organizations
providing Software-, Platform-, or Infrastructure-as-a-Service
via the cloud).
 Security issues faced by their customers.
 The provider must ensure that their infrastructure is secure
and that their clients’ data and applications are protected while
the customer must ensure that the provider has taken the
proper security measures to protect their information

5. Do we Get Better Service At Lower Cost
When we Move To Cloud Services?
 Clouds are also comparatively easy to manage and bring down the
costs.
 Security in cloud computing is much better than a scattered network.
 Cloud computing ensures that everyone uses the same computing
standards with less down-time.
 Accessibility from anywhere via multiple devices.
 Brings down overall hardware and software costs.

6. How cloud computing
works??????
In a cloud computing
system, there's a
significant workload
shift. Local computers
no longer have to do all
the heavy lifting when
it comes to running
applications. The only
thing the user's
computer needs to be
able to run is the cloud
computing
system's interface
software, which can
be as simple as a Web
browser, and the
cloud's network takes
care of the rest.

7. Top Threats For Cloud Computing
 Threat no 1: Security threats
 Threat no 2: Outages
 Threat no 3: Malicious Insiders
 Threat no 4: Lack of information

9. TYPES OF CLOUD COMPUTING

10. Comparing Public, Private, and Hybrid
Cloud Computing Options
Cloud computing
comes in three
forms:
 Public clouds.
 Private clouds.
 Hybrids clouds.
Depending on the
type of data clouds
there are different
levels of security
and management
required.

11. Public Clouds
A public cloud is one in which the services and infrastructure are
provided off-site over the Internet. These clouds offer the greatest level
of efficiency in shared resources; however, they are also more
vulnerable than private clouds. A public cloud is the obvious choice
when
 There standardized workload for applications is used by lots of
people, such as e-mail.
 Incremental capacity is needed (the ability to add computer capacity
for peak times).
 When doing collaboration projects.
 When doing an ad-hoc software development project.
Many IT department executives are concerned about public cloud
security and reliability. Take extra time to ensure that you have security
and governance issues well planned, or the short-term cost savings
could turn into a long-term nightmare.

12. Private Clouds
A private cloud is one in which the services and infrastructure are
maintained on a private network. These clouds offer the greatest level of
security and control, but they require the company to still purchase and
maintain all the software and infrastructure, which reduces the cost
savings. A private cloud is the obvious choice when
• The business is the data and your applications. Therefore, control and
security are paramount.
• The business is part of an industry that must conform to strict security
and data privacy issues.

13. HYBRID CLOUDS
A hybrid cloud includes a variety of public and private
options with multiple providers. By spreading things out over
a hybrid cloud, you keep each aspect at your business in the
most efficient environment possible.
 Company wants to use a SaaS application but is concerned
about security. The SaaS vendor can create a private cloud
just for your company inside their firewall. They provide
you with a virtual private network (VPN) for additional
security.
 Company can use a public cloud to interact with the clients
but keep their data secured within a private cloud.

14. Project Phase Typical Cost Categories
PLANNING AND DESIGN Planning end solution
Internal and external resources
Pilot and proof of concept
IMPLEMENTATION software, hardware and licensing fees
consulting cost
development and testing cost
OPERATIONS On going license/maintenace fees
operations personnel
system admin
MAINTENANCE &
MODIFICATIONS upgrades or enhancement
other incremental expenses

15. CLOUD COMPUTING IN MID-SIZED MARKET
 Cloud computing has been gaining increasing attention from businesses
of all sizes as a way to obtain secure access .
 Midsize companies, those with 100–999 employees, can benefit from
cloud-based capabilities.
 The variety of applications and approaches to cloud solutions and the
different resources companies will make a difference in how these
companies implement cloud computing into their business.

16. IS CLOUD
COMPUTING A
GOOD OPTION FOR
KEECO ??
• Cloud computing holds the potential
to dramatically change the businesses
that adopt it, even if the technologies
are only used internally.
• There are some benefits that can
potentially change the game for many
firms that are willing to be very
proactive in managing potential
downside.

17. VARIOUS SERVICE PROVIDERS THAT KEECO CAN CONSIDER FOR CLOUD
COMPUTING
 Akamai
 Amazon
 Areti Internet
 Enki
 Fortress ITX
 Joyent
 Layered Technologies
 Rackspace
 Salesforce.com
 Exostart
 Terremark
 XCalibre

18. Constraints in implementing cloud at KEECO`
How to over come it ??
• The main constraint of KEECO is that a cloud computing
should be accessible to and from china.
• The service providers that gives access to china are
ExoStart
Joyent

19. Joyent is a global cloud computing software and
service provider that offers an integrated suite of
software and services designed for enterprises.
 JoyentCloud delivers virtual machines, server
hosting, and cloud services in a unique cloud
architecture designed for rapid scaling and high
performance production apps.
 Joyent Smart Machines run inside container-based
virtualization.

20. How does ExoStart work??
 Exostart’s Forum Pass is a cloud-based, enterprise-class,
complete B2B project collaboration service
offering. It’s built on the Microsoft SharePoint 2010
platform.
 What truly makes Forum Pass unique is its security.

21. These advanced capabilities allow
Forum Pass to promote:
File sharing and document
management
Secure joint proposal
management
Net meetings and
concurrent/real-time working
environments.
Process management and
routing
Product design and collaboration

22. CONCLUSION
O Thus from my study and research Cloud is not
a matter if it fits small business or not, cloud is
a matter of time.
O Cloud computing started mid-2008 and is now
growing and developing so in few years from
now cloud will not be an option but a MUST
specially for small to medium size companies
who wishes to stay competitive taking into
consideration the cost reduction in terms of
network and hardware infrastructure, servers,
licenses, support etc…………
