Why Cloud?

Everyone’s got a Cloud solution these days. Cloud computing is designed to solve the issues companies are facing including faster business service delivery and flexible and elastic use of resources.

  • Service Based – Well defined interfaces that require very little to no training for the end user.
  • Scalable and Elastic – I need to spin up 4 more servers now (the Cloud aim: On Demand Self Service).  The cloud computing model aims to make slow service delivery a by-gone. And while we are at it, of those 80 servers I have, what is obsolete?  Maybe I need 40 servers and half the RAM and a third of the drive space (the Cloud aim is to stop over-provisioning of IT resources)
  • Shared – Utilization of the same pool of resources.
  • Metered by Use – Pay by use.  I need 10 machines for 2 months during the Xmas season for the increased B2C influx and then I’d like to dump them when I don’t need them come January (the Cloud aim: Pay as you Go)
  • Uses Internet Technologies

Now to beat a dead horse a bit.  We already defined Public Cloud, Private Cloud and Hybrid Clouds in the linked words in this sentence.

Public Cloud (Amazon EC2, Rackspace, Terremark, etc.) – pros: cheap, super fast cons: scary security, where is it stored (Privacy and Regulatory laws)?, what else is being housed on the same servers (Porn perhaps)?

Private Cloud (VPNs are a great example of this) – pros: strong security if done correctly, knowledge of where your servers/data resides cons: more expensive, about as fast as setting up you own internal corporate server, what does unused capacity cost the business (monetizing the unused capacity)?

Hybrid Private/Public Cloud – We can link the Private Cloud to the Public Cloud via VPN.  Both Public and Private model to allay concerns of the pros & cons above in Public vs. Private Cloud computing.

Issues:

1.  Not Ready for “Prime Time”: Current SaaS (Software as a Service) and IaaS (Infrastructure as a Service) offerings aren’t meeting demands for businesses yet.  There is a lot of wait and see going on as well as awaiting maturity of the product market.  Most companies want Cloud services but aren’t ready to commit and or purchase them.

2.  Re-branding of existing services: re-branding of VPN and physical server frameworks are being re-branded as “Cloud” services.  Remember when ValueJet renamed itself AirTran? Same service, new name!

Bottom line: Evaluate your preparedness and acceptance of risk.  Assess now!
