Kubernetes co-founder Craig McLuckie is as tired of talking about Kubernetes as you are – gpgmail


“I’m so tired of talking about Kubernetes . I want to talk about something else,” joked Kubernetes co-founder and VP of R&D at VMware Craig McLuckie during a keynote interview at this week’s Cloud Foundry Summit in The Hague. “I feel like that 80s band that had like one hit song — Cherry Pie.”

He doesn’t quite mean it that way, of course (though it makes for a good headline, see above), but the underlying theme of the conversation he had with Cloud Foundry executive director Abby Kearns was that infrastructure should be boring and fade into the background, while enabling developers to do their best work. “We still have a lot of work to do as an industry to make the infrastructure technology fade into the background and bring forwards the technologies that developers interface with, that enable them to develop the code that drives the business, etc. […] Let’s make that infrastructure technology really, really boring. ”

What McCluckie wants to talk about is developer experience and with VMware’s intend to acquire Pivotal, it’s placing a strong bet on Cloud Foundry as one of the premiere development platforms for cloud native applications. For the longest time, the Cloud Foundry and Kubernetes ecosystem, which both share an organizational parent in the Linux Foundation, have been getting closer, but that move has accelerated in recent months as the Cloud Foundry ecosystem has finished work on some of its Kubernetes integrations.

McCluckie argues that the Cloud Native Computing Foundation, the home of Kubernetes and other cloud-native open-source projects, was always meant to be a kind of open-ended organization that focuses on driving innovation. And that created a large set of technologies that vendors can choose from. “But when you start to assemble that, I tend to think about you building up this cake which is your development stack, you discover that some of those layers of the cake, like Kubernetes, have a really good bake. They are done to perfection,” said McLuckie, who is clearly a fan of the Great British Baking show. “And other layers, you look at it and you think, wow, that could use a little more bake, it’s not quite ready yet. […] And we haven’t done a great job of pulling it all together and providing a recipe that delivers an entirely consumable experience for everyday developers.”

He argues that Cloud Foundry, on the other hand, has always focused on building that highly opinionated, consistent developer experience. “Bringing those two communities together, I think, is going to have incredibly powerful results for both communities as we start to bring these technologies together,” he said.

With the Pivotal acquisition still in the works, McCluckie didn’t really comment on what exactly this means for the path forward for Cloud Foundry and Kubernetes (which he still talked about with a lot of energy, despite being tired of it), but it’s clear that he’s looking to Cloud Foundry to enable that developer experience on top of Kubernetes that abstracts all of the infrastructure away for developers and makes deploying an application a matter of a single CLI command.

Bonus: Cherry Pie.

IBM Open-Sources Power ISA, Shares CPU, OpenCAPI Reference Designs

IBM has taken new steps to open the Power architecture further and expand access to its capabilities. Back in 2013, IBM launched the OpenPower Foundation to allow would-be customers to license IBM designs and collaborate with each other. Now, the company has open-sourced the entire Power ISA and contributed a softcore design to the effort, suitable for running on an FPGA. The OpenPower Foundation, which was founded back in 2013, will now become part of the Linux Foundation and the entire project will be overseen by that organization.

IBM has been turning towards open source as a method for reinvigorating its hardware business and stoking interest in its own ecosystem. In addition to open-sourcing the Power ISA, the company has also contributed designs for its Open Coherent Accelerator Processor Interface (OpenCAPI) and Open Memory Interface (OMI). These are the interface protocols that attach the CPUSEEAMAZON_ET_135 See Amazon ET commerce to the rest of the system, and they’re critical to making the total project work. OpenCAPI and OMI are both architecture-agnostic and could theoretically be adapted for usage in both x86 and Power systems, should vendors build compatible solutions.

Ken King, general manager of OpenPower at IBM, told Next Platform that the plan to open source the ISA had been a long time coming:

We started OpenPower six years ago because the industry was seeing the decline of Moore’s Law, and we were seeing the need for more powerful systems to support HPC, artificial intelligence, and data analytics. We needed to find other ways to drive system performance, and with limitations on the processor, the ability to integrate and innovate up and down the stack was becoming more critical. This led to things like NVLink with Nvidia, a close relationship with Mellanox on interconnects, and OpenCAPI for other devices, and we have seen some progress here.

But we are also seeing a shift in the industry, with companies moving to more open hardware. IBM opening up Power to the point where we would license the CPU RTL to others so they could design their own processors was limited in its effect because there were not that many people who wanted to spend many hundreds of millions of dollars – not for license fees, but for full development – to create their own high-end CPU. We did make some progress in opening up our reference designs, and there are over 20 vendors who are now making Power-based systems.

We are seeing interesting developments with the nascent RISC-V architecture, and hyperscalers are hiring their own chip designers and building their own CPUs and interconnects. They are getting into the hardware space, even if they are not going to be hardware vendors, to drive that performance.

OpenCapi-Roadmap

OpenCAPI roadmap.

Under the Linux Foundation, IBM and other members will vote on the future of the standard, including feature set expansions and new capabilities. IBM can continue to make changes to its own ISA for its own purposes, but all other modifications require a membership vote. Members are required to maintain compatibility with the base ISA. Permission to make a non-compliant change will require a unanimous vote. King has openly stated that he hopes Intel will be willing to explore the benefits of using OpenCAPI now that the standard is available in this method, leading to a convergence of support between OpenCAPI and CXL, Intel’s competing interconnect standard.

IBM is hoping that completely open-sourcing the ISA will spur adoption and development. There’s some reason for optimism. Another open-source ISA, RISC-V, has been generating many headlines and interest from various silicon vendors. Current RISC-V CPUs, however, are all low-end embedded hardware. In theory, Power might be an easier lift if its toolchains are more mature and better-featured.

“The opening of the Power ISA, an architecture with a long and distinguished history, will help the open hardware movement continue to gain momentum,” Mateo Valero, Director of Barcelona Supercomputing Center, told InsideHPC. “BSC, which has collaborated with IBM for more than two decades, is excited that IBM’s announcements today provide additional options to initiatives pursuing innovative new processor and accelerator development with freedom of action.”

Though it hasn’t spent much time in the limelight of late, Power was once a major challenger to Intel’s competing x86 architecture in the server world. In recent years, the OpenPower initiative has enjoyed support from a number of companies, with over 250 members as of 2016. Today, it still enjoys market share in the HPC space — the Summit and Sierra supercomputers are #1 and #2 in the world. The third machine is based on custom Sunway architecture. The highest-powered x86 computer is China’s Tianhe-2A, based on the Xeon E5-2692v2. There’s nothing stopping a company from taking Power into new markets (at least in theory), though it would be quite difficult to convince smartphone vendors to rally around Power as opposed to ARM. Still, open-sourcing the architecture can’t hurt its uptake effort.

We’d expect to see the most energy and excitement around Power in servers and HPC because that’s where the core of IBM’s efforts have historically been focused. But we wouldn’t be surprised to see the ISA popping up in other places, either.

How Pivotal got bailed out by fellow Dell family member, VMware – gpgmail


When Dell acquired EMC in 2016 for $67 billion, it created a complicated consortium of interconnected organizations. Some, like VMware and Pivotal, operate as completely separate companies. They have their own boards of directors, can acquire companies and are publicly traded on the stock market. Yet they work closely within the Dell, partnering where it makes sense. When Pivotal’s stock price plunged recently, VMware saved the day when it bought the faltering company for $2.7 billion yesterday.

Pivotal went public last year, and sometimes struggled, but in June the wheels started to come off after a poor quarterly earnings report. The company had what MarketWatch aptly called “a train wreck of a quarter.”

How bad was it? So bad that its stock price was down 42% the day after it reported its earnings. While the quarter itself wasn’t so bad, with revenue up year over year, the guidance was another story. The company cut its 2020 revenue guidance by $40-$50 million and the guidance it gave for the upcoming 2Q19 was also considerably lower than consensus Wall Street estimates.

The stock price plunged from a high of $21.44 on May 30th to a low of $8.30 on Aug 14th. The company’s market cap plunged in that same time period falling from $5.828 billion on May 30th to $2.257 billion on Aug 14th. That’s when VMware admitted it was thinking about buying the struggling company.

IBM is moving OpenPower Foundation to The Linux Foundation – gpgmail


IBM makes the Power Series chips, and as part of that has open sourced some of the underlying technologies to encourage wider use of these chips. The open source pieces have been part of the OpenPower Foundation. Today, the company announced it was moving the foundation under The Linux Foundation, and while it was at it, announced it was open sourcing several other important bits.

Ken King, general manager for OpenPower at IBM, says that at this point in his organization’s evolution, they wanted to move it under the auspices of the Linux Foundation . “We are taking the OpenPower Foundation, and we are putting it as an entity or project underneath The Linux Foundation with the mindset that we are now bringing more of an open governance approach and open governance principles to the foundation,” King told gpgmail.

But IBM didn’t stop there. It also announced that it was open sourcing some of the technical underpinnings of the Power Series chip to make it easier for developers and engineers to build on top of the technology. Perhaps most importantly, the company is open sourcing the Power Instruction Set Architecture (ISA). These are “the definitions developers use for ensuring hardware and software work together on Power,” the company explained.

King sees open sourcing this technology as an important step for a number of reasons around licensing and governance. “The first thing is that we are taking the ability to be able to implement what we’re licensing, the ISA instruction set architecture, for others to be able to implement on top of that instruction set royalty free with patent rights,” he explained.

The company is also putting this under an open governance workgroup at the OpenPower Foundation. This matters to open source community members because it provides a layer of transparency that might otherwise be lacking. What that means in practice is that any changes will be subject to a majority vote, so long as the changes meet compatibility requirements, King said.

Jim Zemlin, executive director at the Linux Foundation, says that making all of this part of the Linux Foundation open source community could drive more innovation. “Instead of a very, very long cycle of building an application and working separately with hardware and chip designers, because all of this is open, you’re able to quickly build your application, prototype it with hardware folks, and then work with a service provider or a company like IBM to take it to market. So there’s not tons of layers in between the actual innovation and value captured by industry in that cycle,” Zemlin explained.

In addition, IBM made several other announcements around open sourcing other Power Chip technologies designed to help developers and engineers customize and control their implementations of Power chip technology. “IBM will also contribute multiple other technologies including a softcore implementation of the Power ISA, as well as reference designs for the architecture-agnostic Open Coherent Accelerator Processor Interface (OpenCAPI) and the Open Memory Interface (OMI). The OpenCAPI and OMI technologies help maximize memory bandwidth between processors and attached devices, critical to overcoming performance bottlenecks for emerging workloads like AI,” the company said in a statement.

The softcore implementation of the Power ISA, in particular, should give developers more control and even enable them to build their own instruction sets, Hugh Blemings, executive director of the OpenPower Foundation explained. “They can now actually try crafting their own instruction sets, and try out new ways of the accelerated data processes and so forth at a lower level than previously possible,” he said.

The company is announcing all of this today at the The Linux Foundation Open Source Summit and OpenPower Summit in San Diego.
