2. Introduction
What is cloud computing
How cloud computing works
Uses of cloud computing
How cloud computing stores data
Factors affecting cloud computing
Pros and Cons of cloud computing
Building blocks of cloud computing
3. Cloud computing is where computing
resources are stored in a virtual online
“cloud” rather than a local desktop or
organization data center.
4. • Cloud Computing is a general term used to
describe a new class of network based
computing that takes place over the
internet.
• Basically a step on from utility components.
• Using the internet for communication and
transport provide hardware , software and
networking services to clients.
6. It helps us to use applications without
installation
We access the personal files and data from
any computer with internet access.
This technology allows much more efficient
computation by centralizing storage, memory
and processing
9. There are two major factors that effect
cloud computing services:
Usage fees
Bandwidth caps
10. PROS CONS
Reduces IT costs security
Increase processing power privacy
Allows us to access our files
anywhere
Usage fees
Uses a moderately priced
device
Bandwidth caps
11. There are three building blocks of cloud
computing :-
SAAS (Software as a service)
PAAS (Platform as a service)
IAAS (Infrastructure as a service)
12. SaaS is a cloud computing layer most people
have interacted with one and are likely to
use in their day to day lives .
Software as a service is where computing
applications are accessed through the
internet .
SaaS eliminates the need to download ,install
and run applications on local computers.
These applications are managed by a third
party vendor.. Example: Google docs.
13. A one to many model is used for software
delivery.
Software management is done from a
centralized location.
Access to the commercial application is
gained via the internet.
The end users need not worry about software
patches and upgrades.
Application programming interfaces enable
integration with other applications.
14. No fixed costs
Device interdependecy
collaborative-allows multiple sharing of
information
Constant updates
15. o The main disadvantage of SaaS is that it’s,
limited to browser capabilities.
o Another drawback of SaaS is the security
concerns that surround it.
16. o PaaS is a software environment used to
develop and run applications .
o PaaS can be defined as a computing platform
that enables the creation , testing , and
implementation of software easily and
quickly without the complexities of buying
and maintaining the infrastructure and
additional software.
Examples: Google app engine , MS Azure and
force.com
17. Has services that allow testing,
development, hosting and maintenance of
applications.
The platform can be accessed by multiple
users.
Development support
Tools with handle subscription and billing
management.
18. Cost reduction
Streamlined application development and
management
Increased mobility
Reduced technical maintenence
19. The main disadvantage of PaaS is its
restrictive nature. Despite the fact that it
makes the development of online
applications easy , developers are restricted
to the programming language and tools
provided by the PaaS Vendor.
20. The final and most fundamental layer of
cloud computing is infrastructure as a
service, it is sometimes referred to as
hardware as a service. In this computing
infrastructure, networking and storage are
delivered over the internet. An enterprise
can purchase the services on demand.
Example: Amazon web services
IaaS is the most fundamental building block,
it covers the areas where PaaS and SaaS do
not; making at the ideal solution.
21. Resources and infrastructure are distributed
as a service.
Enables dynamic scaling
Multiple users utilize a single piece of
hardware.
