what is cloud computing1
What is Cloud Computing
  • Resource availability is a key factor to achieve prosperity of any society,
  • Particularly important are computing resources
      • e-banking, e-government, e-learning, e-commerce, e-social
  • To attain their full potential, computing resources need to be efficiently utilized preferably in an aggregated manner.
  • The demand for computing resources can now be met by utility computing, grid computing, and most recently cloudcomputing.

Arab Academy for Science and Technology, Jan. 5, 2011

what is cloud computing utility computing
What is Cloud ComputingUtility Computing
  • Utilitycomputing providers rent capacity on computing resources that they maintain
    • Metered computing: analogous to electric power (Pay per use)
    • Resources often virtualized and shared by multiple tenants
    • Example: Amazon Elastic Compute Cloud (estimated $60 USD/Month for one EC2Instance for 24hrs/day-7days/week). Pay per use option
      • Amazon Elastic Compute Cloud (Amazon EC2) web service provides resizable compute capacity in the cloud
      • Designed to make web-scale computing easier for developers.

what is cloud computing utility versus cloud computing
What is Cloud ComputingUtility versusCloud computing
  • Cloud computing not only provides raw computing resources, but also hosts the applications that use these resources.
    • Applications usually accessed via a web browser.
    • User data typically stored on provider's file systems.
  • Underlying computing infrastructure concealed from user.
    • Example: gmail servers are concealed from users
  • Cloud Computing middleware systems are available for building clouds and their applications (e.g., Eucalyptus and Hadoop)

Arab Academy for Science and Technology, Jan. 5, 2011

what is cloud computing cluster and grid computing
What is Cloud ComputingCluster and Grid Computing
  • A cluster is a collection of tightly coupled computing servers.
    • Usually co-located.
  • A computing grid is a distributed collection of computing servers.
    • While the servers may be dedicated resources, they could be borrowed from idle desktop computers.
    • A grid middleware system is needed to support the development and assessment of service-oriented grid systems and applications (e.g., CROWN-C) http://www.wrgrid.org.uk/Resources/Leaflets/WRG_COLAB_Sept2007.pdf

What is Cloud ComputingGrid and Community Computing
  • Community computing projects assemble a grid of donated CPU resources using volunteers idle cycles
    • Example: The BOINC software by UC Berkley is an Open-source software for volunteer computing and grid computing.
    • BOINC lets you donate your idle computer time to science projects like SETI@home, Climateprediction.net, Rosetta@home, Folding@home, World Community Grid, and many, Folding@home (http://boinc.berkeley.edu/download.php)
    • Uses Screensavers (windows) or low-priority process (linux)

What is Cloud ComputingGrid and Cloud Computing
  • Resource Sharing:
    • Grid enhances fair sharing of resources across organization.
    • Cloud provide resources according to demand so no actual sharing of resources due to the isolation through virtualization
  • Virtualization:
    • Grid: virtualization covers both data and resources (flat file and database).
    • Cloud adds virtualization for hardware resources too
  • Security:
    • Grid: security is not seriously explored.
    • Cloud: Each user has a unique access to the virtualized environment

What is Cloud ComputingGrid and Cloud Computing
  • Usability:
    • Clouds are easily usable hiding the deployment details from the user.
    • Grid: hard to manage
  • Payment model:
    • Cloud use pay- per use model.
    • Grid fixed rate per service.
  • Scalability
    • Both Grid and cloud deals with scalability
  • Heterogeneity:
    • Both cloud and grid support aggregation of heterogonous hardware and software.

Benefits of Cloud Computing
  • Cloud computing is a model that supports everything as a service (XaaS), e.g, the X changes to an I for,

Infrastructure as a Service(IaaS)

Physical resource set (PRS):

is hardware dependent or vendor dependent

Virtual resource set (VRS): is built on top of PRS to run in multivendor cloud

Benefits of Cloud Computing
  • Human as a service (HaaS): Amazon Mechanical Turk (MTurk) is one of the suites of Amazon Web Services, a crowdsourcingmarketplace that enables computer programs to coordinate the use of Human Intelligence to perform Tasks (HITs) which computers are unable to do
  • Workers can work on-line and make money by choosing from thousands of posted HITs.
  • US-based CrowdFlower has introduced a cloud labor service that connects organizations searching for temporary workers to refugees in Kenya , The iPhone app helps a business outsource a basic task, such finding a phone number for marketing departments at various companies and entering them into a spread sheet.
  • Workers in Kinya have completed 158,000 tasks, individuals earn as much as $28/week, 8 times what they get from typical jobs in a refugee camp”

Benefits of Cloud Computing
  • The Provided services in the Cloud are the following:
    • Virtualized physical resources,
    • Virtualized infrastructure,
    • Virtualized middleware platforms
    • Virtualized business applications
  • Cloud computing reduces the need for advanced hardware on the clients side
    • Clients can use inexpensive small Net Books and virtually have the processing power of an expandable Grid computing system
    • No need to buy a set of software or software licenses
    • Data is no longer confined to the user's hard drive, will be able to access data and applications from anywhere at any time. There is no more lost data due to hard drive failures
    • Corporations would save money on IT support, and No need for space to house expensive hardware and software servers.

  • Service Providers: Development Services, or Build and Test Services,
    • Software Engineering Methodologies and tools
    • How to manage clouds for Application Lifecycle Management
    • The Cloud manager can limit projects to certain clouds, control costs, manage security, or supplement resources during peak use
  • Service Users: easily usable clouds, hiding the deployment details from the user using virtualization,
  • Security and privacy are the biggest concerns
  • Cost accounting data , and usage tracking for Multiple Clouds. “if the utility models were adequate, the challenges to cloud

Computing could be solved with electricity-like solutions, but they can not”
