The term “server consolidation” has frequented the top of the agenda of those who are responsible for IT in organizations. To reduce the number of servers follow the desired reduction in energy costs and lower resource requirements for refrigeration equipment, besides the obvious space savings.
It is understandable that the wave of consolidation has arrived in full force in IT departments and their success has been contagious. The tactic is adopted across the IT industry, large and medium enterprises. Even small structures have been streamlined to the limit.
The trend is followed by providers that now offer solutions that match that philosophy. All this euphoria hides a fundamental fact: the mass adoption of such technology will result in weaker systems and severe risks.
The more bodies rotate on a dedicated server, the worse will be the consequences of possible outages.
Systems configured virtualization followed a traditional architecture that have stopped services in certain cases of falling services. It can be a mail server, or application. Of course all the associated machinery will feel the effects of unavailability still be somewhat limited.
In the case of server consolidation this picture changes and range of risks is inflated and with worse consequences for small businesses that have a greater number of applications running on the server.
In times of virtualization processes and transactions, such unavailability is dreaded by IT and abhorred by the management of the business.
