Nutanix says cloud is a concept, not a place – and guess who it reckons has nailed the concept?

Adds security and networking to platform, hoping you use it to repatriate apps

Nutanix has used its annual .NEXT conference to advance the argument that public clouds can be wastefully expensive places in which to run workloads – unless they're managed by Nutanix so they can be returned to another environment at your convenience.

That may seem a somewhat brazen argument, given Nutanix has spent the last couple of years touting deals that ensure its software stack runs in AWS, Azure, Google, and IBM's clouds.

Nutanix CEO Rajiv Ramaswami made his argument by referencing analysis from venture capital firm Andreessen Horowitz asserting that public cloud has seduced business with the lure of on-demand infrastructure, paying only for rightsized rigs, and relieving organisations of many IT chores.

But Andreessen also argues that cloud is expensive, and the costs it adds to operations suppress company value - to the tune of $100 billion and perhaps as much as $500 billion.

Nutanix and Ramaswami like those numbers very much. The CEO thinks they make a case for reconsidering when and if to use hyperscale clouds. Cue much discussion of the importance of being able to repatriate workloads from the cloud when it makes sense to do so.

As the purveyor of a hybrid cloud platform that can run in many environments, Nutanix stands to benefit from repatriation – whether you fancy bringing your IT in-house or just the chance to take advantage of different clouds when it makes sense to do so.

The hyperconverged upstart has added a few things to its platform to advance its cause. Enhanced network virtualization promises to allow virtual private clouds that span multiple actual clouds, and will in future add microsegmentation services to automate development of security policy based on workload behaviours. Failover to public clouds is an option Nutanix feels has appeal as organisations review their disaster recovery readiness.

Integration with security vendor Qualys will help to automate patching, while Nutanix's software-defined storage wares are now better at spotting and deflecting ransomware.

The company also claims to have improved its ability to run analytics workloads.

A deeper partnership with Citrix was also announced at the conference. That will see the application publishing vendor's apps able to run across multiple Nutanix-tended clouds.

Getting closer to Citrix will be welcome news to some customers, as will the enhancements to Nutanix's platform.

But the fact remains that Nutanix is the challenger in the hybrid cloud market –– and maybe not the most important one. Amazon Web Services is increasingly reaching out of its cloud and into almost any other location a computer might be found, IBM is nowhere near done figuring out what to do with OpenShift, Microsoft's hybrid efforts are firmly pushing Azure Stack HCI, and Google is well under way defining Anthos and hybrid Kubernetes.

Google and AWS will find it hard to argue against clouds as the best place to do everything, but can still – along with Microsoft and IBM – make the same points Nutanix advances about the importance of workload mobility. And they can deliver on them.

Nutanix is standing for something distinct in a busy market, which is laudable. It can point to 20,000 happy customers and increasing financial maturity as the fruits of its labours. ®

    A widespread distro that many of its users don't even know they have

    Version 3.16.0 of Alpine Linux is out – one of the most significant of the many lightweight distros.

    Version 3.16.0 is worth a look, especially if you want to broaden your skills.

    Alpine is interesting because it's not just another me-too distro. It bucks a lot of the trends in modern Linux, and while it's not the easiest to set up, it's a great deal easier to get it working than it was a few releases ago.

  • Verizon: Ransomware sees biggest jump in five years
    We're only here for DBIRs

    The cybersecurity landscape continues to expand and evolve rapidly, fueled in large part by the cat-and-mouse game between miscreants trying to get into corporate IT environments and those hired by enterprises and security vendors to keep them out.

    Despite all that, Verizon's annual security breach report is again showing that there are constants in the field, including that ransomware continues to be a fast-growing threat and that the "human element" still plays a central role in most security breaches, whether it's through social engineering, bad decisions, or similar.

    According to the US carrier's 2022 Data Breach Investigations Report (DBIR) released this week [PDF], ransomware accounted for 25 percent of the observed security incidents that occurred between November 1, 2020, and October 31, 2021, and was present in 70 percent of all malware infections. Ransomware outbreaks increased 13 percent year-over-year, a larger increase than the previous five years combined.

    These were the words of communication and collaboration platform Mattermost's founder and CTO, Corey Hulen, speaking to The Register about open source, sovereignty and audio bridges.

    "Some of the history of Mattermost is exactly that problem," says Hulen of the issue of closed source software. "We were using proprietary tools – we were not a collaboration platform before, we were a games company before – [and] we were extremely frustrated because we couldn't get our intellectual property out of those systems..."
