A Berkeley View of Cloud Computing… and Chargeback

Earlier this year Berkley’s Electrical Engineering and Computer Sciences department published an article with Berkley’s view on What Cloud Computing is.

1. The illusion of infinite computing resources available on demand, thereby eliminating the need for Cloud Computing users to plan far ahead for provisioning;

2. The elimination of an up-front commitment by Cloud users, thereby allowing companies to start small and increase hardware resources only when there is an increase in their needs;

3. The ability to pay for use of computing resources on a short-term basis as needed (e.g., processors by the hour and storage by the day) and release them as needed;

The article also ranks the top 10 obstacles and opportunities for cloud adoption

  1. Availability of a Service
  2. Data Lock-In
  3. Data Confidentiality and Auditability
  4. Data Transfer Bottlenecks
  5. Performance Unpredictability
  6. Scalable Storage
  7. Bugs in Large-Scale Distributed Systems
  8. Scaling Quickly
  9. Reputation Fate Sharing
  10. Software Licensing
    Nothing here is new and it is probably mutually shared amongst the whole cloud and virtualisation community, however their article provide a resourceful insight on how charge back should work and should be conducted.
    Every day more organisations find themselves in a ocean of VMs that somehow need be accounted and charged back to their internal owners. The adoption of chargeback toolsets will not help this organisations if they don’t have a defined chargeback model.
