Hyper-converged infrastructure: Why software-defined everything might not work for all datacentres Choosing the right converged infrastructure in the first instance can pivot on a trade-off between security and agility requirements Share this item with your network: By Published: 04 Mar 2021 While all datacentres have become in essence defined by their software, going for a fully fledged, software-defined hyper-converged infrastructure (HCI) will not always be the right course for every operator.

Ross Warnock, director at datacentre infrastructure provider and consultancy EfficiencyIT, says the essential trade-off to consider is likely to be between security and agility.
