4. What is Cloud Computing
Cloud computing is an umbrella term used to refer to
Internet based development and services.
5. CONTINU...
Used in Online tools for email,productivity
software, business applications, and data
storage
Eliminates costs related to on-site
installations of hardware, software, and
IT support staff
Available from any location and device
with an internet connection
6. Who are all in the Cloud?
Online email accounts (Gmail, Yahoo)
Social networking sites (Facebook,
Twitter)
Photo sharing sites (Flickr, Picasa)
Search engines (Google, Bing)
Productivity software (Google Docs)
Personal finance software (Quicken,
online banking and bill paying tools)
7. CHARACTERISTICS:
A number of characteristics define cloud data,
applications services and infrastructure:
Remotely hosted: Services or data are hosted
on remote infrastructure.
Ubiquitous: Services or data are available
from anywhere.
Commodified: The result is a traditional
utilities, like electricity - you pay for what you
would want!
8. Economics:
Cloud computing users avoid Capital
Expenditure (CapEx) on hardware, software, and
services when they pay a provider only for what
they use.
Shared infrastructure and costs, low
management overhead, and immediate access to
a broad range of applications.
9. Layers:
(i) Client :
A cloud client
consists of
computer hardware
and/or computer
software that is
specifically
designed for delivery
of cloud services
10. (ii) Application :
Cloud application services or "Software
as a Service (SaaS)" deliver software as a
service over the Internet.
eliminating the need to install and run the
application on the customer's own
computers and simplifying maintenance
and support.
11. (iii) Platform :
Cloud platform services or "Platform as a
Service (PaaS)" deliver a computing
platform and/or solution stack as a
service.
It facilitates deployment of applications
without the cost and complexity of buying
and managing the hardware and software
layers.
12. (iv) Cloud Infrastructure as Service:
"Infrastructure as a Service (IaaS)"
delivers computer infrastructure,
typically a platform virtualization
environment as a service
Rather than purchasing servers,
software,network equipment, clients
instead buy those resources as a fully
outsourced service
The service is typically billed on a
utility computing basis and amount of
resources consumed
13. (V) Server :
The servers layer consists of computer
hardware and/or software products
that are specifically designed for the
delivery of cloud services
It including multicore processors, cloud
specific operating systems and
combined offerings
16. Hybrid Cloud :
By integrating multiple cloud services users
may be able to ease the transition to public
cloud services while avoiding issues such as
PCI compliance.
A hybrid cloud environment consisting of
multiple internal and/or external providers "will
be typical for most enterprises".
17. Cloud storage :
Cloud Storage is a
model of networked
Computer data
storage.
Data is stored on
multiple virtual servers,
generally hosted by third
parties, rather than being
hosted on dedicated
servers.
18. The Intercloud :
The Intercloud is an
interconnected global
"cloud of clouds" and
an extension of the
Internet "network of
networks" on which it is
based.
19. Issues :
(i) Security data storage and transmission
encryption, user authentication, and
authorization (data access) practices.
worry about the vulnerability of remote data
to such criminals as hackers, thieves...etc
(ii)Reliability – To avoid the loss of data using
redundant storage techniques, but it is still
possible that a service could crash.
20. (iii) Ownership – In cloud, some people worry
that they could lose some or all
of their rights or be unable to protect the
rights of their customers.
(iv) Data Backup – Cloud providers employ
redundant servers and routine data backup
processes.
some people worry about being able to
control their own backups .
21. Data Portability and Conversion – Porting
and converting data is highly dependent on the
nature of the cloud provider’s data retrieval
format.
Multiplatform Support – An issue for IT
departments using managed services is how
the cloudbased service integrates across
different platforms and operating systems.
23. Future of cloud Computing:
Cloud computing is still in
its infancy, and the future
is still being defined.
Made possible due to high-
speed Internet.
No matter the country, anyone can
compete in this market and define its the
future.
24. Future of cloud Computing...
Technology will evolve from services
into full-fledged operating systems.
Google, Microsoft, and Apple are
three likely contenders in the future of
the industry.
