There is a huge disconnect between the DevOps world and most current enterprise IT organizations. One element in the gap is that developers do not want to know about infrastructure. Another is that the operations team does not trust developers to make changes to the production infrastructure. Developers want to focus on their application and the value it delivers to the organization. Developers want to know the characteristics of the infrastructure but do not want to build it or operate it. As a result, DevOps does not mean the end of the operations team. In fact, I see the reverse as being essential. The operations team is absolutely critical to the success of DevOps methodologies. The developers must be able to trust that the infrastructure has specific characteristics: characteristics like performance, connectivity, availability, and uniformity. To enable this trust, I believe that the operations teams are going to need to become more like developers. I call this OpsDev.

In this ever-changing world of IT, the legacy of today was once the future of yesterday: namely, hypervisors. Hypervisors are now considered legacy, even though they are seriously underutilized due to issues with fear, uncertainty, and doubt around using these resources to their fullest. The new technology is containers. However, where are the operational tools to support containers? Where are the procedures? Where are the developers who understand distributed systems? We are moving toward containers at lightning speed without answers to those questions and many more. To move to containers today, we need a strategy.
Docker, Kubernetes, and Mesos are generating a lot of discussion as the future of application development. We are seeing significant progress towards having these methodologies adopted by enterprises for application development. We have even been hearing that VMware is the new legacy, since containerised applications don’t always need a hypervisor. These “modern application” methods are replacing older client server and early web architectures as the preferred way to develop applications. Some people are saying that this means the end of the road for the old applications and the infrastructures that run these applications.
I’ve been speaking a lot lately about the importance of IT governance, especially as it relates to driving cloud (public, private, hybrid) adoption in the enterprise. Although IT governance is critical to the success of having a flexible and agile enterprise, having an overarching enterprise architecture to show how all the components of the enterprise are related and to guide the decisions that affect IT is just as important.
Forrester recently completed an in-depth study entitled The Forrester Wave™: Server-Hosted Virtual Desktops (VDI), Q3 2015, which offers a complete analysis of significant providers in this space, including Citrix, Dell, Microsoft, and VMware. Overall, Citrix XenDesktop was rated high in most categories; however, one area, management tools, showed a significant deficit.
