The step by step evolution of an organisation from a Small Business to a Large Enterprise necessitates infrastructure growth which meets the varying needs of the organisation. Infrastructure not just in the technology sense but the growth of Human Resources, Finance, Recruiting, Compliance, Governance and other administrative functions. These are the backbones which support the sales and operational arms of the company.
The glue to bind all these moving pieces together is often the underlying technology solutions that have been implemented. As the company is adding these functions to strengthen its core, so too must the technology keep pace. In an ideal scenario the technology will be the pacemaker out in front that will allow for growth without major difficulty.
Supporting all these functions will inevitably lead to growing complexity. Traditionally technology providers accepted such and simply provided more resources to the customer when required.
Example: you add network appliances, servers and storage where required. More staff are hired based on the staffing model to support the additional hardware and so on.
Some entrepreneurs disagreed with this notion and set forth to break the paradigm. What came out of this was a technology segment referred to as Hyper Converged Networks. In simple terms, the goal of the Hyper Converged Network is to allow growth, while reducing management complexity and providing a bundled set of services all accessible through one portal. In a traditional environment, this would have required multiple systems from different vendors.
