Private Cloud: Nadhan’s Top 5 Don’ts

David Linthicum from InfoWorld offers 5 simple tips for building effective private clouds.  If Linthicum’s hints can be characterized as a Top 5 To Do list, what are the Top 5 Don'ts? When I tried addressing the Don’ts independently, some interesting overlaps emerged between the two.


Here are the Don’ts that you Do want to read:

  1. Don't do it for a single application. Take an enterprise-level perspective in alignment with the business objectives. Even if you are the business owner for a portion of the applications portfolio, you should consider private cloud computing only as part of an enterprise-level strategy with well defined business goals.
  2.  Don't do it because it is cool technically. It is better to be a relatively late cloud computing entrant doing it right rather than being yet another addition to the bandwagon without any proper business justification. Moving into the private cloud is a business decision that involves a technological paradigm shift. CIOs and CFOs must work together to make these decisions.
  3. Don't ignore Service Orientation. It behooves you to have a SOA strategy in place for the enterprise before considering the private cloud. Most of Linthicum’s hints also apply to having an effective SOA strategy. Private cloud opens up the availability of services provisioned for physical infrastructure components, which could be an integral part of the SOA strategy. Service Oriented Cloud Computing Infrastructure, The Open Group’s first technical standard for the Cloud is worth a quick read (Free PDF download).
  4. Don't just assume Cloud Computing is always right. Applications need to be assessed to determine their suitability for the cloud. There are some applications that are better left alone in their traditional environment. Deploying the wrong application to the cloud could result in new challenges for you to deal with. Despite all the hype, it is not true that all the IT environments are going to be on the cloud some day. Traditional, non-cloud environments are here to stay for a long time for good reasons.
  5. Don't think Private Equals Secure. Concerns about security are still valid even though you may be within the firewalls of your enterprise in a private cloud. Applications are deployed in new environments opening them up to new vulnerabilities. You must revisit the security strategy and standards for the enterprise and the manner in which it is realized in the private cloud.

I am usually not a proponent of calling out the don'ts. However, IT has consistently exhibited an urge to jump on the latest bandwagon in town -- private cloud being no different -- starting small then going viral across the enterprise. One fine morning, the CEO is suddenly faced with the question, How did we land up here !! Hence the Don'ts.


Are you already doing some of these don'ts?  Do let me know.


HP has an interesting paper on how to choose the right cloud computing solution for your organization if you’re interested in learning more. Also, check out HP’s cloud computing info on hp.com and for something really cool, check out how Paul McCartney used hybrid delivery for his digital library.
