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 …

Nested Virtualization in Azure

Microsoft adds nested virtualization to Azure

Microsoft’s added a new instance type to Azure and the ability to run nested virtualization.

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. While the company could still point to annual revenue grazing towards US$3bn, software companies don't often improve their health after bad years. With VMware …

Check your privilege: CoreOS's container tech rkt gets priv-escalation defense on Intel chips

Non-big IT vendors: Trying to understand where startups fit in tech

Sysadmin blog Are startups to be avoided? You'll get different answers depending on who you talk to, but the arguments have relevance for the virtualization and storage markets as, today, most of the innovation is occurring with startups.

VMware's vDare: Build more complexity and silos, or virtualize more

VMworld VMware opened its VMworld 2016 conference asking its customers to “Be tomorrow,” a couplet that was introduced at the event's opening keynote with a performance of poetry that felt like the work of a slick self-help spruiker. But VMware might just be onto something here, because it knows that in not many tomorrows, serious …

You’ve left too many VMs lying about. You’re a very naughty boy

There’s no doubt about it: cloud computing is a leveller, both outside organisations and in. But do we really want a free-for-all democracy in which anyone can procure anything at will? And if not, how do we stop it? Back in the day, the operations staff held the keys to the kingdom. They got to decide who got what hardware, …
