Broadcom buying VMware could create an edge infrastructure and IoT empire

Hypervisor giant too big to be kept ticking over like CA or Symantec. Instead it can wrangle net-connected kit


Comment Broadcom’s mooted acquisition of VMware looks odd at face value, but if considered as a means to make edge computing and the Internet of Things (IoT) more mature and manageable, and give organizations the tools to drive them, the deal makes rather more sense.

Edge and IoT are the two coming things in computing and will grow for years, meaning the proposed deal could be very good for VMware’s current customers.

An Ethernet switch that Broadcom launched this week shows why this is a plausible scenario.

The machine boasts an Arm-designed subsystem, is intended for use in cars, and was “designed to address the growing bandwidth need for in-vehicle networking applications and facilitate the adoption of software defined vehicles.”

A software-defined vehicle is essentially a car that can have its software upgraded. It’s assumed we’ll soon expect things like updates to the AI or algorithms that helps a car handle icy roads, because it’s not as if that software will stop evolving when a vehicle leaves the factory. So when winter comes around, automakers will try to sell you this year’s model (pun intended) and may also be selling the data your car collects to improve that model.

Can you think of a company that’s good at packaging and publishing apps to myriad devices, and to servers on the edge? VMware can do that, and does it already. Do automakers really want to build their own stack to distribute software? Probably not. And most probably use VMware already, somewhere.

Broadcom also certainly knows that automakers want more tech in their products, but worry the computers that could make future cars fabulous will increase complexity, weight, and cost.

The Linux and virtualization communities noticed this ages ago, which is why and have worked on lightweight operating systems and hypervisors that will allow a single on-board computer to suffice for most of a car’s needs, by isolating workloads. Toyota went shopping for such a system in 2017, the same year in which the Xen Project made automotive uses a priority for its hypervisor. In a world of CPU dies carrying chiplets of different capacities, a good hypervisor can shunt a car’s cabin temperature sensors onto slow cores and let LIDAR and other sensors work with nice fast processors.

Can you think of a company that has a lightweight Linux, an excellent hypervisor, and can use it to manage VMs, containers, and isolating workloads? A company with a deep understanding of how to use virtualisation tech baked into chips?

VMware ticks all those boxes.

Broadcom’s switch also boasts “an advanced rule-based packet filter engine that can adapt to different vehicle operation modes to enhance driving safety.”

That matters because carmakers know that as more automation finds its way into vehicles, there will be moments when traffic from a certain sensor needs priority. Drivers won’t complain that the car radio skipped a beat if they’re alive to tell the tale.

Can you think of a company that is strong in software-defined networks and network function virtualisation, and has expertise across many devices?

By now you can guess my answer.

Cars are a very decent market: about 80 million a year roll off the production line.

But the billions of connected IoT devices that will soon be built each year have similar security, software deployment, and manageability requirements to cars.

And while they won’t have Broadcom switches inside, they may well have other Broadcom silicon.

So maybe Broadcom sees VMware as a way to build a stack that elevates it from a chip designer with a seemingly strange software annex to a chip designer with a very broad IoT software deployment and management solution.

At this point, users who have made VMware the heart of their datacenter might take comfort from Broadcom having a plausible plan to keep their supplier thriving. They’d be right to also worry that Broadcom’s previous enterprise software acquisitions – CA Technologies and Symantec – have not exactly set the world on fire since being bought, delivering seven percent year on year growth in FY 2021, amid reports of considerable layoffs among former Symantec staff. If either Symantec or CA is doing new or interesting things, Broadcom isn't telling the world about those activities.

But VMware is currently a $13bn business, massively larger than CA or Symantec when acquired, and also a leader in its field. Broadcom would be daft to turn its back on VMware’s existing business and leadership position to chase an IoT dream. Instead, VMware’s current business could fund development of the IoT stack.

And with every current VMware client almost certain to do something with the IoT, the virtualization giant gives Broadcom a ready-made customer base. VMware itself banks on this for its efforts to move towards containers, with a pitch that nobody wants one management stack for VMs and another for Kubernetes. Broadcom can make the same argument for IoT.

So maybe Broadcom buying VMware at a time its shares have been dragged down by inflation and war isn’t the cynical act of corporate raiding and/or bargain hunting it appears at first flush.

But it’s not you I need to convince of that. Broadcom needs to convince Michael Dell and private equity firm SilverLake, as they together hold more than half of VMware shares. ®

PS: Yes, we know Broadcom more or less quit the IoT world in 2016. That was mainly small wireless gadgets. The rise of edge computing and 5G means lots more devices in more places.

    VMware-powered sovereign cloud not going to challenge hyperscalers, and won't be repeated beyond Japan

    Updated Hitachi has taken a modest step towards becoming a public cloud provider, with the launch of a VMware-powered cloud in Japan that The Register understands may not be its only such venture.

    The Japanese giant has styled the service a "sovereign cloud" – a term that VMware introduced to distinguish some of its 4,000-plus partners that operate small clouds and can attest to their operations being subject to privacy laws and governance structures within the nation in which they operate.

    Public cloud heavyweights AWS, Azure, Google, Oracle, IBM, and Alibaba also offer VMware-powered clouds, at hyperscale. But some organizations worry that their US or Chinese roots make them vulnerable to laws that might allow Washington or Beijing to exercise extraterritorial oversight.

  • Broadcom to 'focus on rapid transition to subscriptions' for VMware
    Offers comforting vision for core customers, products, channel – though warns efficiencies are coming

    Broadcom has signaled its $61 billion acquisition of VMware will involve a “rapid transition from perpetual licenses to subscriptions.”

    That's according to Tom Krause, president of the Broadcom Software Group, on Thursday's Broadcom earnings call. He was asked how the semiconductor giant plans to deliver on its guidance that VMware will add approximately $8.5 billion of pro forma EBITDA to Broadcom within three years of the deal closing – significant growth given VMware currently produces about $4.7 billion. And subscriptions was the answer.

    Krause also repeatedly said Broadcom intends to invest in VMware’s key product portfolio and is pleased to be acquiring a sales organization and channel relationships that give it reach Broadcom does not currently enjoy.

  • Confirmed: Broadcom, VMware agree to $61b merger
    Unless anyone out there can make a better offer. Oh, Elon?

    Broadcom has confirmed it intends to acquire VMware in a deal that looks set to be worth $61 billion, if it goes ahead: the agreement provides for a “go-shop” provision under which the virtualization giant may solicit alternative offers.

    Rumors of the proposed merger emerged earlier this week, amid much speculation, but neither of the companies was prepared to comment on the deal before today, when it was disclosed that the boards of directors of both organizations have unanimously approved the agreement.

    Michael Dell and Silver Lake investors, which own just over half of the outstanding shares in VMware between both, have apparently signed support agreements to vote in favor of the transaction, so long as the VMware board continues to recommend the proposed transaction with chip designer Broadcom.

  • Why Wi-Fi 6 and 6E will connect factories of the future
    Tech body pushes reliability, cost savings of next-gen wireless comms for IIoT – not a typo

    Wi-Fi 6 and 6E are being promoted as technologies for enabling industrial automation and the Industrial Internet of Things (IIoT) thanks to features that provide more reliable communications and reduced costs compared with wired network alternatives, at least according to the Wireless Broadband Alliance (WBA).

    The WBA’s Wi-Fi 6/6E for IIoT working group, led by Cisco, Deutsche Telekom, and Intel, has pulled together ideas on the future of networked devices in factories and written it all up in a “Wi-Fi 6/6E for Industrial IoT: Enabling Wi-Fi Determinism in an IoT World” manifesto.

    The detailed whitepaper makes the case that wireless communications has become the preferred way to network sensors as part of IIoT deployments because it's faster and cheaper than fiber or copper infrastructure. The alliance is a collection of technology companies and service providers that work together on developing standards, coming up with certifications and guidelines, advocating for stuff that they want, and so on.
