The wave of hyperconverged computing hase been going on for a long time now. A logical continuation of converged computing, it takes the same elements but with a greater symbiosis of its components with the virtualization of processing, storage and network. Many even speak of hyperconverged as a data center in a box. What gave rise to hyperconvergence and why should it be considered in the design of modern data centers or in the development of a strategy for deploying a new IT service?
In recent years, the speeches of company executives changed. It is no longer about how things work, but how to deliver services faster and with greater agility. For the organization, it’s a question of remaining ahead or even looking for something to stand out from the competition. This speech questions the place that is left for traditional IT.
The key elements of hyperconverged platforms are: speed of commissioning, flexible capacity growth and lower long-term operating costs. These factors contribute to the agility of the IT function by enabling the rapid deployment of the necessary infrastructure for enterprise applications and services. There is no need to wait for the IT teams responsible for servers, storage and network elements to set up the server, since a hyperconverged platform deploys as a whole by means of an intelligent deployment wizard.
One must look beyond these attractive aspects to question several challenges that they generate. Indeed, we must know the typical use cases of these platforms. The first deployment cases were for Virtual Desktop Infrastructure (VDI). VDI is well served by the hyperconverged because it offers a relatively homogeneous set and a potentially constant and predictable growth. VDI requires efficient storage infrastructures. However, dashboard applications, BI or even artificial intelligence are not intended for such a platform because they have unpredictable loads and their growth is erratic or exponential. One must thoroughly examine the use cases that will take advantage of hyperconvergence before investing in it, or better yet, seek advice from experts.
Beyond technology, there will always be the human challenge. Hyperconverged platforms are numerous and have all their own characteristics. But all are subject to the same potential issue: in large organizations, these platforms, to be well deployed and well used, require concerted efforts from different IT groups who are not always used to working together. No matter the IT project, without the collaboration of these teams responsible for servers, storage and networking, any deployment of a hyperconverged infrastructure is doomed to failure.
