The release of VMware vSphere 5.0 is almost visible on the horizon now.
In the online communities and when talking with colleagues the term ESXi 5 and/or vSphere 5 keep coming up.
The general expectation is that the release will be announced at VMworld 2011 in Las Vegas.
(no promise just a wild guess)
Version 4 of VMware vSphere/ESX(i) is quite suitable for most of our needs, but other players on the hypervisor market (Microsoft, Citrix) are closing the gap fast. So VMware needs to keep innovating to stay ahead and the reputation of VMware demands a new and improved version which will again stun the world. Packed with features with which Microsoft will ‘quick’ it’s customers again until they got it themselves in 2-3 years.
But fortunately the rumors on VMware vSphere 5 look very promising. Of course the configuration maximums will be improved again, not that anyone will come even close, but the added value must be in the new and improved features in my opinion.
