Hybrid IT or Public Cloud?
Recently, I had the privilege of attending a round table to talk about cloud computing and Hybrid IT. The discussion was to share information on where IT professionals were on their cloud journey within their organization and why companies make the jump to hybrid or public cloud.
The attendees were mostly Director and “C” level executives with representation from almost every spectrum of business. Every stage of the cloud journey was represented. There were companies that have everything on premise and companies with 100% of their IT in the cloud. There were very small companies to some of the largest companies in Colorado, as well as local companies and international companies. It was a great cross representation and lead to some interesting conversations.
What I found interesting was why some of these organizations had moved to the cloud and why some had not moved to the cloud. The discussion also arose on when the idea of Hybrid IT made the most sense for a company. There were a few that had a “Cloud First” approach to IT, but most people in the room agreed that Hybrid IT made the most sense. It really depended on the market and the size of the company.
For example, if most of the IT requirements were remote (stores, etc.), the Cloud approach seemed to be prevalent. Larger companies and companies with high security requirements tended to lean more to the on premise or Hybrid approach.
Almost everyone agreed that moving an application (Software as a Service) or setting up a DR site in the cloud is a good way to gain exposure into cloud computing. This is nothing new and has been going on for some time.
Hybrid IT Option
Hybrid IT is an approach to enterprise computing in which an organization provides and manages some information technology (IT) resources in-house but uses cloud-based services for others.
Many customers have applications that will not or should not move to the cloud. The easy example is mainframe and high-end Unix systems that are unlikely going to move to the cloud. At least until the applications are replaced.
Some of the attendees at this event were hesitant to move to the public cloud because of security and privacy concerns. While others had compliance regulations they must meet. These are valid concerns, and one the hybrid IT can help solve.
While privacy and security should be of utmost concern, businesses still need to innovate. The Hybrid IT model can address both concerns. Enterprises that deal with confidential data need the flexibility the Public cloud provides. They have the ability to create a multi-tenant cloud within the hybrid model. This will segregate applications and resources from each other and can be further isolated with VLANs and additional encryption methods.

some level of hybrid infrastructure management
Many businesses have found success using Hybrid IT models that allow them to keep full control over sensitive data, such as customer data or internal communications. They can keep data stored on-premise and readily accessible, while relegating less-sensitive data and workloads in the cloud. The added benefit of maintaining a hybrid solution with an on-premise data center is for disaster recovery and keeping private data out of the public pool. Hybrid IT is the ideal use of public and private resources that maximize cost-savings and productivity, and to minimize latency, privacy and security concerns.
