What is Cloud Computing?
An emerging computing paradigm where data and services reside in massively scalable data centers and can be accessed from any connected devices over the internet.
History
In 1960 when John McCarthy opined that "computation may someday be organized as a public utility”. The term cloud had already come into commercial use in the early 1990s to refer to large ATM networks. In 1999, Salesforce.com was established by Marc Benioff, Parker Harris,and his fellows.They applied many technologies of consumer web sites like Google and Yahoo! to business applications. IBM extended these concepts in 2001 and in 2002 amazon.com played a key role in the development of cloud computing by modernizing their data centres.
Cloud Computing Layers
Infrastructure as a Service(IaaS)
Platform as a Service(PaaS)
Software as a Service(SaaS)
Cloud Computing Components
Cloud Application
Cloud Clients
Cloud Infrastructure
Cloud Platforms
Cloud Services
Cloud Storage
Characterstics
COST
DEVICE AND LOCATION INDEPENDENCE
MULTI-TENANCY
RELIABILITY
SCALABILITY
SECURITY
SUSTANIBILITY
Cloud Computing Services
Search Engines
Webmail
Web Based Office
Applications
Online Photo And
Document Sharing
Cloud Computing Services
Large-scale web-based storage and computing power for building your own applications
Hosted Spam filtering
Cloud Computing Providers
Amazon EC2
Google Application Engine
Microsoft Azure
Salesforce.com
Benefits
Ability to scale to meet changing user
demands quickly, usually within minutes
Task oriented
Virtually no maintenance
Easy to develop your own web based applications that run in the cloud
Sharing of peak-load capacity among a large
pool of users, improving overall utilization
Separation of application code from physical
resources
Ability to use external assets to handle peak
loads (not having to engineer for highest
possible load levels)
Not having to purchase assets for one-time or
infrequent intensive computing tasks
Drawbacks
Canned solutions such may not be full featured, or too Task-oriented
Often limited or no technical support available
Often free services display ads
When there are technical issues you may lose
access to your data or your application
No Control
Potential Regulatory Compliance issues
If the company hosting the application goes
out of business you may lose access to your
data or application permanently
You must have an Internet connection
Why adopt cloud?
Access to computing power instantly
On demand allocation and deallocation of resources
More customers minimize capital expenditure.
Sharing of resources
Device and location independence
