2.  The cloud is a computing service that charges you
based only on the amount of computing resources we
use.
 Pay as you go….

3. Cloud computing is a natural evolution of the
widespread adoption of :
 Virtualization
 service-oriented architecture
 autonomic, and
 utility computing..
Details are abstracted from end-users, who no longer have
need for expertise in, or control over, the technology
infrastructure "in the cloud" that supports them

4. What Is Cloud Computing??
Broadly, it is combination of three Computing concepts :
 Grid Computing-Cluster of loosely coupled computers
for a common cause
 Utility Computing-Packaging of computer resources as
a metered
 Service Autonomic Computing-Capable of self
management

5. Key Characteristics
 Agility
 Cost
 Device and
 Reliability
 Scalability
 Security
 location
 independence
 Multi tenancy
 Sustainability

6. Basic Components of Cloud Computing
1)Clients
2)Services
3)Application
4)Platforms
5)Storages
6)Infrastructure

7. Cloud Computing Architecture

8. Cloud architecture, the systems architecture of the software
systems involved in the delivery of cloud computing, typically involves
multiple cloud components communicating with each other over a loose
coupling mechanism such as a messaging queue.
Cloud engineering is the application of engineering disciplines to cloud
computing. It brings a systematic approach to the high level concerns of
commercialization, standardization, and governance in developing, operating
and maintaining cloud computing systems.
It is a multidisciplinary method encompassing contributions from diverse areas
such
as systems, software, web, performance, information, security, platform, risk, and
quality engineering.

9. Cloud Computing Architecture
1)Software as a Service
2)Platform as a Service
3)Infrastructure as a Service
These 3 services encapsulate the basic 6
Cloud Computing Components

10. Software as a Service
• Software as a service features a complete application
offered as a service on demand.
• A single instance of the software runs on the cloud
and services multiple end users or client organizations.
• Eg: salesforce.com , Google Apps
Platform as a Service
• Platform as a service encapsulates a layer of software and provides it as a
service that can be used to build
higher-level services.
Two Perspectives for Platform as a Service
1. Producer:- Someone producing Platform as a Service might produce a
platform by integrating an OS, middleware, application software, and even
a development environment that is then provided to a customer as a
service.

11. 2.Consumer:-
Someone using Process as a Service would see an
encapsulated service that is presented to them through an API.
The customer interacts with the platform through the API, and
the platform does what is necessary to manage and scale itself
to provide a given level of service
Infrastructure as a Service
• “Infrastructure as a service “delivers basic storage and computing
capabilities as standardized services over the network.

12. Cloud Computing Types

13. Public Clouds
A public cloud is one based on the
standard cloud computing model, in
which a service provider makes
resources, such as applications and
storage, available to the general
public over the Internet. Public
cloud services may be free or offered
on a pay-per-usage model.

14. Private Clouds
Private cloud is infrastructure operated
solely for a single
organization, whether managed
internally or by a third-party and
hosted internally or externally.
They have attracted criticism because
users "still have to buy, build, and
manage them" and thus do not benefit
from lower up-front capital costs and
less hands-on management, essentially
"[lacking] the economic model that
makes cloud computing such an
intriguing concept".

15. Hybrid Clouds
•Hybrid cloud is a composition of two or more clouds (private, community, or
public) that remain unique entities but are bound together, offering the benefits of
multiple deployment models. It can also be defined as multiple cloud systems that
are connected in a way that allows programs and data to be moved easily from one
deployment system to another.

19. What is it?
•It can run your web applications on
Google’s infrastructure and easy to scale
for traffic and data storage
•Features
• dynamic web serving,
• persistent storage,
• automatic scaling
Application environment
• Java
• Python

21. iCloud is a cloud storage and cloud computing service from Apple Inc.
announced on June 6, 2011 at the Apple Worldwide Developers Conference
(WWDC) .

22. iCloud =
o Contacts
o Mail
o Calendars
o Apps
o Books
o Backups

23.  The service allows users to store data such
as music files on remote computer servers
for download to multiple devices such as
iOS-based devices, and personal
computers running Mac OS X or
Microsoft Windows.
 It also replaces Apple's MobileMe
service, acting as a data syncing center for
email, contacts, calendars, bookmarks, n
otes, to-do lists, and other data.

24. IBM cloud computing consists
of cloud computing solutions for
enterprises, offered by the global
information technology company

27.  Cloud Computing holds a lot of promise and we
believe that it is likely to be a major influence on
hosting and application development.
 SmarterTools is preparing all of our products for
potential Cloud compatibility in the future because we
have confidence that the incumbent issues will be
satisfactorily resolved as this new technology matures.
