Is it the right time to virtualize?

Picture the scene. You’ve run your legacy infrastructure into the ground. You bought it six or seven years ago with a view to depreciating the hardware over four years, or perhaps even three, so it’s done its time and then some. Now it’s starting to get flakier than you can live with, and as your channel partner’s spares supply …

vSphere scales up, if you're willing to ditch a switch or server

VMware's popped out the first update to vSphere 6.5 and it's unusually interesting for this sort of minor release. Scale is the headline-grabber. You can now run 50,000 VMs in a powered-on vSphere Domain, up from 30,000. That Domain can now register 70,000 VMs, up from 50,000. To wrangle all those VMs, you can now run 15 …

5G is not just a radio: Welcome to the fibre-tastic new mobile world

Analysis When an executive from Nokia, of all companies, said 5G was as much about fibre as wireless, it was clear this was going to be different from previous mobile standards generations. 5G will not be driven by mobile broadband speeds as 4G was. If higher data rates and larger numbers of broadband devices are an mobile network …

Azure Stack's debut ends the easy ride for AWS, VMware and hyperconverged boxen

Analysis Microsoft's formal announcement of Azure Stack changes the cloud market forever, by giving us three distinct types of cloud. Today we have pure-play public cloud from AWS, Microsoft, Google, IBM or what I've heard described as “hybrid virtualization” – the ability to stretch an on-premises private cloud into the public cloud …

Amazon adds Hyper-V file support to its storage gateway

Amazon Web Services dominates the public cloud, but its hybrid cloud story is currently weak. Microsoft, by contrast, is gaining strength in the cloud by the day and its Azure Stack looks like re-defining hybrid cloud by making the on-premises portion indistinguishable from Azure. Azure Stack's preview releases suggest that …

Xen bends own embargo rules to unbork risky Cirrus video emulation

The Xen Project has bent its own rules of vulnerability disclosure for a buggy and possibly exploitable video component that needs urgent attention. It's not a hypervisor escape yet, but as the Xen advisory notes, it could be a pathway to one. The crashable component is a VGA driver, of all things – the default Cirrus video …

It's over? Pat Gelsinger's post vSphere VMware NSX-T opportunity

Sysadmin Blog VMware has recently announced its financial results for 2016, and for a company that's not just satured but that leads the VM market, it had a very good year. Some of this is attributed to accepting that VMware can't beat AWS, so it might as well join them. But VMware's NSX Network Virtualization arguably led the way, doubling …

Citrix looks like it has escaped 'not dead yet' status

In 2015 Citrix was in trouble: the company fired 900 employees and warned it would miss guidance on earnings, endured a profit slump and cleaned out its C-suite.
