Αιθεροβάμονες and cloud computing

Cloud computing is great, it allows great flexibility, scalability and organizational freedom but it is not a panacea.

Here is a small list of things to consider.

  1. Cloud computing is not safer computing. It still has many single points of failure, probably more than before. This  time the failure points are vendor associated. If your vendor goes down so does your service.
  2. Cloud computing is not safer computing. Your security team, you have one right, must now work on at least {vendor X service X application } security interaction lattices.
  3. It requires administrators of greater skill. Debugging large scale networked applications means that your people must be able to read, and understand, tcpdump logs.
  4. It runs over networks. If your link is down your computing is down. Even if it is not down you sure are not receiving any benefits from it.
  5. It is not necessarily cheaper, if you migrate license based servers unto a cloud platform you still need to pay the server licenses plus the platform costs.
  6. Cloud computing as a term is new, as a practice is as old as the first data center farm. Sure there was not virtualisation back then, still.

Please somebody post a positive review of cloud computing so I can link to the pros of it.

Αιθεροβάμονες: Greek for skywalkers 🙂

    * Cloud computing does not make system administration obsolete. In fact it transforms the developer of a system into its administrator.

    * Who audits the cloud?

    * SLAs are for lawyers. Try resolving a cloud SLA-mess.

  2. Angele, here is a list of some pro’s:
    1) No capital investment
    2) No H/W investment
    3) No IT expertise investment
    4) Application irrelevant of “current technology” (who cares on what platform it runs, as long as it IS running)
    5) Zero or low cost of “new repleases”
    6) Avoid vendor lock-in
    7) Pay-as-you-go. Want more? Pay more?
    8) Enjoy know-how that a “in-house” IT department is difficult to master
    9) A SaaS application is “always” a web-enabled application
    10) Lets the business focus on non-IT processes

    Your points are relevant for SaaS which is a subset of cloud computing in general. I am more concerned with complicated infrastructures that try to switch servers and services to the cloud computing paradigm.

    Still it is indeed easier for a non tech savvy company to lease Software from the cloud rather than if it purchased the resources outright. Yet allow me to disagree on the vendor lock in issue. There is tremendous vendor and platform lock in. Suppose that someone has a salesforce.com based CRM, how easy can they move to another vendor ?
