2 outline Cloud computing: Approach and vision Resource Provisioning in Cloud systems: Cloud Systems: IaaS, PaaS, SaaS Using Cloud Systems in practice Cloud system providers Open source Cloud middleware

3 What is Cloud Computing?

4 What is the cloud IT as a service Cloud allows access to services without user technical knowledge or control of supporting infrastructure Best describe in terms of what happened to electrical power over 100 years ago Now computers are simple devices connected to the leader cloud Data processing, storage and software application that used to run locally are now being supplied by big central computing station, They are becoming in essence computing utilities

5 Traditional ways of provisioning resources

6 Expand your Infrastructure! Buy new servers, increase your software costs, provision more datacenter capacity!!

7 Look to the cloud! Pay for the bandwidth and server resources that you need. When your push is done then turn the whole thing off! The Three Reasons to Cloud Compute : annotation_id=annotation_308603&feature=iv&src_vid=sgujaizkwre&v=oibkmjr rdjq

8 Style of computing & usage model

28 SaaS, PaaS, and IaaS

29 Infrastructure as a Service (IaaS). Amazon S3 (Data storage/file system), SimpleDB (non-relational database) EC2 (computing servers). Rackspace Cloud Drive (Data storage/file system), Cloud Sites (web site hosting on cloud) Cloud Servers(computing servers). GoGrid IBM Cloud Hosting (web site hosting on cloud) Cloud Storage (Data storage/file system). Smart Business Storage Cloud Computing on Demand (CoD)

30 Platform as a Service (PaaS). Googles force.com Microsoft AppEngine is a development platform based upon Python and Java Apex a development platform based upon a proprietary programming language Azure provides a development platform based upon.net.

31 Software as a Service (SaaS) Google IBM Zoho Google Docs, GMail, Google Calendar and Picasa LotusLive inotes, a web based service that provides messaging and calendaring capabilities to business users has vast suite of online products similar to Microsoft office suite.

32 Software as a Service (SaaS) applications processing Photo editing software Online file storage Twitter related applications Digital Video Photo Album Editing documents, spreadsheets and powerpoints Navigation: google Maps, Yahoo maps, e-commerce software

33 outline Cloud computing: Approach and vision Resource Provisioning in Cloud systems: Cloud Systems: IaaS, PaaS, SaaS Using Cloud Systems in practice Cloud system providers Open source Cloud middleware

34 OpenNebula

35 OpenNebula OpenNebula provides different interfaces to interact and manage physical and virtual resources.

36 OpenStack The OpenStack Open Source Cloud Mission: to produce the ubiquitous Open Source Cloud Computing platform that will meet the needs of public and private clouds regardless of size, by being simple to implement and massively scalable. Originated by Rackspace and NASA In 2010
