Cloud Computing

1
Cloud Computing

• Project A Simple Application with Hadoop

2
Brienf introduction

• Typical cloud computing providers deliver common
  business applications online which are accessed
  from a web browser, while the software and data
  are stored on servers.

3
Cloud Computing Existence

• Cloud computing is derived from following terms
  but do not confuse with these architectures.
• Grid Computing (form of distributed computing and
  parallel computing)
• Autonomic computing (computer systems capable of
  self-management )
• Client-Server
• Mainframe(powerful computers used mainly by large
  organizations for critical application,erp,etc. )
• Utility Computing ( Sharing resources,computations
  )

Cloud computing overview
5
Architectural model
Software As A Service (SaaS )
Platform As A Service (PaaS)
Infrastructure As A Service(IaaS)
6
Application layer(SaaS)

• Eliminating the need to install and run the
  application on the customer's own computers and
  simplifying maintenance and support.
• Examples SalesForce, Gmail , Yahoo! Mail
  ,Quicken Online
• Advantages Free , Easy to use
• Disadvantages Limited functionality, no control
  or access to underlying technology.

7
Platform Layer(PaaS)

• It facilitates deployment of applications without
  the cost and complexity of buying and managing
  the underlying hardware and software layers.
• Containers Locked in Development Environment
• Closed environments
• Examples Google App Engine(You can develop your
  code using Google App Engine , Heroku(Ruby Cloud
  Platform), Mosso,Engine Yard,SalesForce Dev
  Platform)
• Disadvantages Restricted to what is available.

8
Infrastructure layer(IaaS)

• Typically a platform virtualization environment,
  as a service.
• Rather than purchasing servers, software, data
  center space or network equipment, clients
  instead buy those resources as a fully outsourced
  service.(Billing depend on your activity like
  utility computing)
• Advantages Full control of environments and
  infrastructure
• Disadvantages Limited competition
• Examples AmazonEC2(Elastic Compute
  Cloud),Amazon S3(Simple Storage Service)

9
Cloud computing benefits

• Scalability(Performance is monitored)
• Reduce Costs(like electricity,hardware
  improvement,error fixing)
• Security
• Availability ( uptime )
• Reliability ( Automatically replacements,
  employement in best practises in IT)
• Ease of Use(Control your infrastructure via
  software)
• Risk ( Nothing to buy , cancel immediately, throw
  it out )

10
Cloud Computing Benefits

• Device and location independence
• Versionless Software(when if you upgrade the
  software , users dont need to download the new
  patch )

11
Cloud computing Pitfalls

• You must trust the company which provides cloud
  computing environment.(Google,Amazon)
• Lost control comes with handing over your data
  and information
• Depending on third-party to ensure the security
  and confidentiality of data and information
• If your cloud host disappears, where does your
  information go?

12
Using areas of Cloud computing

• Gaming(OnLive company announced that on this
  january games will be played via internet without
  the need of gaming console or any hardware
  requirements.)
• Data Storing , Retrieving , Conversion
• Computing high degree computations.
• Everything whatever you need.

Cloud Computing Examples

• The NY Times ( storing articles and data
  conversions faster)Amazon EC2
• Nasdaq ( stock market )Amazon S3
• Major League BaseballJoyent
• ESPNRightscale using Amazon EC2

• British Telecom3Tera
• Taylor WoodrowGoogle Apps
• CSSAmazon EC2
• ActivisionAmazon EC2
• Business Objects (A SAP Company)Rightscale using
  Amazon EC2
