Cloud Computing: Public, Private or Hybrid Cloud?
Choose the wise course
Public Cloud: This debate continues to go on in many organizations we speak with today. Newer companies tend to leverage the cloud as much as possible, much of it has to do with the simple fact that they want to focus on the business platform, not necessarily building a data center per sea. DevOps teams don't want to be constrained in any way, so they leverage cloud infrastructures and off they go. I can't say I blame them, I would definitely do the same.
The issues that comes up with this model is cost....uncontrolled cost. The default tools available are inadequate to a large extent. To successfully deliver a cost effective, automated and standardized cloud solution you will need a Cloud Management Platform is required.
Control vs. Expense
Private Cloud: This model offers greater control in both cost and infrastructure, however you will need to have adequate facility to ensure proper power and cooling. You also need to work on capacity planning. As more than likely you will need to have a solid 3 to 6 month's worth of capacity in place as a buffer. Cloud providers use this buffer in there ROI calculations, as they see this expenditure as an unnecessary expense.
While I agree in principal with adding this expense into your calculus, you have to weight this expense against how much capacity you will need going forward versus the resources you have internally to manage all of these assets. Every customer is different in this respect. We welcome a discussion around this subject with you and your organization.
The best of both worlds
Hybrid Cloud: Some applications are inherently made for the cloud. For instance, Email. Email has been around since the begin of the internet and as such, it’s in just about every organization conducting business today. Before Gmail and O365, you had to house your own email server, and there are merits to continuing this practice. Case in point, if you are a governmental agency, either Federal or State, you may want to continue to house your own Email Server.
That said, for the clear majority of organizations on the planet, it makes far better sense to leverage the cloud for such a service. Both O365 and GMail have far more redundancy in their respective clouds than any organization under the sun. You simply cannot build a better service internally.
To illustrate, imagine you own a portion of your local Post Office. You must pay for the local mail carriers, sorting machines, the space, as well as those goofy little trucks that come around your neighborhood to deliver your mail. This is simply ludicrous, not to mention cost prohibitive to say the least.
For this reason, I continue to advise my clients to put in the cloud what makes absolute sense and keep only what you want to control and optimized.
