Whats a Cloud ?
  • "A Cloud is a type of parallel and distributed
    system consisting of a collection of
    interconnected and virtualized computers that are
    dynamically provisioned and presented as one or
    more unified computing resources based on
    service-level agreements established through
    negotiation between the service provider and
    consumers (Buyya et al.)
  • A large-scale distributed computing paradigm
    that is driven by economies of scale, in which a
    pool of abstracted, virtualized,
    dynamically-scalable, managed computing power,
    storage, platforms, and services are delivered on
    demand to external customers over the Internet
    (Foster et al.)
  • Start point October/November 2007 - IBM Blue
    Cloud

3
Types of clouds
  • Public clouds (or external clouds)
  • resources are dynamically provisioned on a
    fine-grained, self-service basis over the
    Internet, via Web applications or Web services.
  • the cloud is hosted, operated, and managed by a
    third-party vendor from one or more
    data/computing centers
  • organizations/customers lease shared resources
    from public clouds, effectively becoming
    infrastructure tenants rather than owners
  • computing becomes a public utility
  • Private clouds (or internal clouds) emulate cloud
    computing on private networks
  • Hybrid clouds merge multiple internal and/or
    external clouds

4
IaaS, PaaS, SaaS
  • Infrastructure as a Service (IaaS)
  • provides computing environments/infrastructure
    i.e., hardware, software
  • the provisioned infrastructure can dynamically
    scale up and down depending on the actual needs
  • Amazon EC2 and S3
  • Platform as a Service (PaaS)
  • high-level integrated environment to build and
    deploy applications
  • restrictions on the type of applications
  • but scalable platform
  • Googles App Engine for deploying Web
    applications
  • Software as a Service (SaaS)
  • delivers software to consumers through the
    Internet
  • Salesforce online CRM (Customer Relationship
    Management) Services Live Mesh from Microsoft
    files and folders synchronization

5
Other XaaS offerings
  • Storage as a Service 
  • Data(base) as a Service (DaaS)
  • Process as a Service - Business Process as a
    Service
  • Network as a Service (NaaS)
  • Integration as a Service 
  • Security as a Service - Identity as a Service
  • Testing as a Service

6
Visit of a Cloud vendor web site
  • http//www.ibm.com/ibm/cloud/
  •  Values to customers include
  • Reducing IT management complexity and skill
    requirements
  • Sharing resources among multiple applications
  • Accelerating application launches
  • Supporting both existing and emerging,
    data-intensive workloads

7
Characteristics
  • From the customer point of view
  • Scalability
  • Reliability
  • Flexibility
  • Cost
  • Security and Privacy
  • Performance
  • Ubiquitous and fast access
  • Quality of Service
  • Service Level Agreement
  • Pricing system
  • Simple to use
  • From the internal point of view
  • Virtualization
  •  Grid  management

Comparison of some cloud platforms
From Foster et al.

Example Amazon EC2/S3
  • Compute Cloud EC2 (Elastic Cloud Computing)
  •  Private  virtualized servers ( instances )
    of different types
  • Example High-CPU Extra Large Instance
  • 7 GB of memory
  • 20 EC2 Compute Units
  • 1690 GB Storage
  • Pricing on a per hour basis for each instance
    type from 0.084/hour for the smallest
    "On-Demand" virtual machine running Linux to 12x
    more for the largest one running Windows (Nov.
    2009). The data transfer charge ranges from 0.08
    to 0.15 per gigabyte, depending on the volume
  • Data Cloud S3 (Simple Storage Service)
  • from 0.55 to 0.15 per GB-month, bandwidth
    usage (from 0.08 to 0.15 per GB) requests
    (from 0.01 to 0.1 per 1000 requests)
  • 102 billion objects stored files (March 2010)
  • data transfer is charged by TB / month data
    transfer, depending on the source and target of
    such transfer.

    are doing entirely cloud based or entirely cloud
    inspired
