Cloud Computing from a Software Engineering Perspective

What is cloud computing
What is Cloud Computing?

  • A coherent, large-scale, publicly

    accessiblecollection of compute,

    storage, and networking resources

  • Available via Web service calls

    through the Internet

  • Short- or long-term access on a pay per use basis


Motivation for cloud computing
Motivation for Cloud Computing

  • Internet-based service provisioning

    • Provision is usually overestimated to deal

      with usage peaks

    • Peaks are rare and relatively short

    • Estimates indicate that data centers only

      use about 10-15% of their capacity

  • Over-provisioning is expensive

    • Electricity and cooling costs for low demand servers

    • High personnel costs for managing and maintaining the physical and hardware infrastructure


Motivation for cloud computing1
Motivation for Cloud Computing

  • Application deployment is non-trivial

    • Need to configure hardware, OS, network, storage devices, and install all the required application software (web server, application server, DBMS)

  • Global financial crisis

    • Cloud computing as a cost-effective alternative to cut down IT costs


Motivation for cloud computing2
Motivation for Cloud Computing

  • Increasing market and public interest

    • MerrylLynch estimates a cloud computing market of US$160 billion in 2011

    • Gartner estimatesthat in 2011 75% of all softwareservices will usesome type ofcloudinfrastructure


From the software engineering perspective
From the software engineering perspective

  • An attractive deployment and operation

    solution

  • Cloud computing offers specific programming features that may influence the way software is developed


Course objectives
Course objectives

  • Introduce the concepts of Cloud computing

  • Overview existing approaches and techniques,

    and provide guidelines for their usage in all

    phases of software lifecycle


Content overview
Content overview

  • Introduction to Cloud Computing

  • Deploying Infrastructure as a Service (IaaS)

  • Delivering Platform as a Service (PaaS)

  • Relevant Software as a Service (SaaS) examples (Google and Facebook)

  • Industrial seminars (we are inviting IBM, Microsoft, GoGrid)


Cloud computing from a software engineering perspective
Exam

  • Evaluation mainly based on a project

  • Groups: 4-5 graduate students, possibly, supervised by a PhD Student

  • Peer reviewed paper

  • Project presentation


Projects
Projects

  • We will ask the industrial speakers to propose two-three projects

  • Projects proposed by us

    • Monitoring: extending d and j-Cloud

    • Deploying an application on IBM IaaS infrastructure and on Amazon: what is the difference?

    • Data management in the Cloud

    • SOA vs. Cloud

    • QoSspecification at multiple level of abstractions

    • Advanced Cloud patterns…

  • You can propose projects if you wish!


Course schedule
Course schedule

  • Lectures in May, from May 2nd to May 30th

    • Monday 14.30-16.00

    • Wednesday 14.30-16.00

    • Last lecture June the 11th 14.30-16.00

    • Schedule of lectures is sharp (academic quarters already counted in the schedule)!

  • Projects will be assigned by the end of the second week of course (but the sooner the better)

  • Project papers to be submitted by June 11th

  • Review process between June 12th and June 26th

  • Final project presentations and evaluations by the first half of July
