  1. 1. Impact in Software Maintenance
  2. 2. What is Cloud Computing?   Is an expression which describe a variety of computing concepts that involve a large number of computers connected through a real-time communication network such as the Internet.  is a synonym for distributed computing over a network, and means the ability to run a program or application on many connected computers at the same time.
  3. 3. Shares characteristics with?   Client-Server Model:  Grid computing  Main frame computer  Utility computing  Peer-to-peer  Cloud gaming
  4. 4. Types of Cloud delivery models??   IaaS-Infrastructure as service; server, storage and network hardware. Eg, Amazon EC2, Azure Services Platform, DynDNS, Google Compute Engine, HP Cloud, iland, Joyent, LeaseWeb, Linode, NaviSite, Oracle Infrastructure as a Service, Rackspace Cloud, ReadySpace Cloud Services, ReliaCloud, SAVVIS, SingleHop, and Terremark  PaaS-Platform as service; App development and Deployment platform. Eg,AWS Elastic Beanstalk, Cloud Foundry, Heroku, Force.com, EngineYard, Mendix, OpenShift, Google App Engine, Windows Azure Cloud Services and OrangeScape.  SaaS- Software as service; Application delivered to end user. Eg, Google Apps, Microsoft Office 365, Onlive, GT Nexus, Marketo, and TradeCard.
  5. 5. Impact in s/w maintenance???   Cloud computing is a natural evolution of the widespread adoption of virtualization, service- oriented architecture, and utility computing.  With the cloud model, you LOSE CONTROL over physical security. In a public cloud, you are sharing computing resources with other companies.  Cloud applications UNDERGO CONSTANT FEATURE ADDITIONS, and users must keep up to date with application improvements to be sure they are protected.  Stored data might not be secure and data may be lost.
  6. 6. Goal???   is to allow users to take benefit from all of these technologies, without the need for deep knowledge about or expertise with each one of them.  Unlimited storage capability  Improved performance.  Device independence
