Networking

Red Hat Summit attendee snapshot

This post was contributed by Pam Derringer.

Some came to network. Others to learn. And one came to pick up a prize.

My very unscientific sampling of conference-goers turned up a mix of reasons that motivated people to attend the recent Red Hat Summit, which equaled or exceeded last year’s event, despite the economic downturn and competition from VMware.

But learning seemed to be the prime motivator. For one thing, the assistant of a workshop presenter observed that the company’s technical workshop was more crowded than the general one, which dovetailed with my experience at other sessions. So I’m guessing that attendees, as a whole, were after highly detailed information to help them do their jobs rather than more topical overviews.

And I’ve just got a hunch that KVM and the coming Red Hat Virtualization platform were a big draw. But you could learn something about this remotely, via Webcasts, news articles, or other outlets. So the real advantage to being there is the additional networking factor.

Two attendees whose primary purpose was networking included Steve Giovannetti, CTO of Hub City Media, and Michael Howard of the U.S. Navy’s Spaware System Center in Charleston, S.C. As a new Red Hat/JBoss Catalyst partner, Hub City Media’s main goal in attending (in addition to being an exhibitor) was “getting to know folks and connecting with customers,” Giovannetti said.

Giovannetti said Red Hat’s vision is “great,” and praised its decision to switch to the KVM hypervisor. Although KVM “has a long way to go,” it’s good that Red Hat will support both KVM and Xen in the interim. “Getting all the virtualization vendors to cooperative will be a challenge… but, ultimately, customers will demand portability,” he said.

Howard, one of three government IT staffers I met at the Summit (a remarkable percentage), also viewed the conference as a networking opportunity. Howard’s main task with the Navy the past four years has been to promote the use of open source in the government and offer user feedback to vendors like Red Hat.

“If I give the open source community our feedback, the taxpayers save millions and the government gets software development for free,” he said.

A Red Hat Enterprise Linux customer, the Navy also is using Red Hat’s JBoss Java application platform and is keenly interested in ensuring that JBoss continues in a strong direction, Howard said.

“JBoss has been great,” he said. “Three of the best JBoss developers in the world work for us.”

David Pullman, a systems administrator for the National Institute of Standards and Technology, said he wants to learn more about KVM because NIST is getting ready to expand its use of virtualization. NIST currently has a small virtualization project with Xen and uses a third-party vendor for high availability and live migration. KVM and Red Hat’s SPICE virtualized desktop both sound interesting, he said.

The lone prize-winner I met at the conference was Rick Gideon, chief operating officer of ecommerce.com. Gideon came to the Summit because his company won the JBoss Innovation award for outstanding architecture.

Based in Columbus, Ohio, Gideon’s firm hosts 500,000 websites and collaborated with EnterpriseDB, Hyperic, Zimbra and others to build an intelligent platform for websites that can be provisioned automatically and dynamically, shifting services as needed based on business rules, he said. The platform runs on Red Hat and JBoss.

“We’re looking to begin partnerships, “ Gideon said. “We’ll be building and deploying [the new system] this year.”

Red Hat’s virtualization suite based on KVM

Red Hat has announced their virtualization strategy for 2009, kicking off another week with a webcast and press releases on some pretty big changes for the market. Red Hat shared that these changes were in response to market demands for virtualization. Navin Thadani, senior director of virtualization business at Red Hat shared that the big three obstacles for virtualization are cost, performance, security and scalability, and that the company’s strategy aims to help customers overcome these.

The company’s virtualization products (launching in the next three to 18 months) include:

• Red Hat Enterprise Virtualization Manager for Servers
• Red Hat Enterprise Virtualization Manager for Desktops
• Red Hat Enterprise Virtualization Hypervisor
• RHEL 5.4
• Red Hat Enterprise Linux Advanced Platform

The biggest change is a shift to using the kernel virtual machine (KVM) hypervisor, and shifting away from Citrix’s XenServer. This move is the next logical step, following Red Hat’s acquisition of Qumranet in September 2008. Qumranet came with virtualization solutions, including its KVM platform and SolidICE offering, a virtual desktop infrastructure (VDI).

In the company’s webcast, the question was asked “Why does the industry need another hypervisor?” Despite the fact that is amused some in the IT world, Thadani coolly stated that while Xen was the best hypervisor on the market in 2007 when RHEL 5 was released, “the KVM hypervisor has demonstrated that it offers superior capabilities… so it will be the strategic direction for the future development of our virtualization product portfolio.” He also explained that Red Hat will continue to support Xen until 2014.

Thandani said that by choosing KVM, performance woes would be resolved, citing up to 98% bare-metal performance. He highlighted that KVM, as part of the Linux kernel, takes advantage of the development work that has gone into Linux, including the hardening effort. Additionally, Red Hat and other developers have worked with the government on SELinux, a built-in Linux security component missing from other hypervisors in the marketplace.

Current virtual machine (VM) deployments max out in the 1,000s of machines, and thus they are unable to meet current business needs for more complex operations. Thadani shared that Red Hat’s Enterprise Virtualization Manager for Servers is designed for large-scale systems management, and is capable of scaling to thousands of hosts with Red Hat’s new search-driven user interface, which allows administrators to easily manage a large number of machines, scaling up to the tens of thousands of VMs. High-performance virtualized machines is the area that Red Hat is positioning itself to lead in, according to Thadani.

The stand-alone Red Hat Virtualization Manager for Servers is designed to be implemented with shops less familiar with enterprise Linux. According to the company, it is:

A new, richly featured virtualization management solution for servers that will be the first open source product in the industry to allow fully integrated management across virtual servers and virtual desktops, featuring Live Migration, High Availability, System Scheduler, Power Manager, Image manager, Snapshots, thin provisioning, monitoring, and reporting.

Thadani explained the difference between the stand-alone and integrated virtualization management offerings, equating them to the difference between a point-and-shoot camera and a SLR camera.

“From the stand-alone standpoint, we’ve designed it to be easy-to-use and easy to deploy,” says Thadani. “It is for enterprises without a lot of Linux experience, and we’ve made it easy to use. It’s a new market for Red Hat.”

To sum it all up, Red Hat is harnessing the power and current buzz in caused by virtualization technology and taking advantage of the current economic climate to move into new markets. No pricing has yet been released for the products, but it’s open source.

Open source to shine despite dim economy

In the final hours of 2008, Roger Burkhardt, president and CEO of Ingres, shared his predictions about the future of open source.

Here are summaries of his predictions:

1. As the economy worsens, adoption of open source software will increase .
2. Open source adoption will accelerate across the full infrastructure software stack and into applications.
3. SaaS and cloud computing solutions will grow and pull open source with it.
4. Mergers and acquisitions of open source vendors will continue.
5. Competition from open source will drive proprietary software vendors to take the first steps in changing their business models.
6. Open source stacks will emerge from strong market partnerships.
7. Systems integrators will guarantee first-year cost savings for migrations to open source.

For the most part, I’m with him. As budgets tighten, it only makes sense that “free” will flourish. We hear that consumers are only looking for sales these days, so why wouldn’t companies? With this increase generally, and as more acceptance and trust of open source occurs, it seems natural that it will extend through the stack and through more applications (e.g., Vyatta has been busy releasing three open source networking appliances in 2008). And perhaps the upside of a down job market is that some programmers, with free time on their hands, can finish projects they had on the back burner. In 2008, we heard a lot of buzz about the cloud, and this cost-conscious computing model pairs well with open source. If you buy the cloud hype, you can easily see the increased opportunity for open source adoption that it provides.

We know that open source gained ground in the enterprise, and we even saw major proprietary software vendors change their tune (if not their business models) — ceding some ground to open source devotees.

What are your predictions for open source? Share them below or make your case against Burkhardt’s divinations.

Cisco router too costly? Vyatta wants to help

Vyatta Inc., the startup with attitude vying to take on the mighty Cisco Systems Inc., is seeking to expand its toehold in the networking market with the introduction of a larger router and security networking appliance — and at a fraction of the cost of comparable Cisco gear.

The Belmont, Calif., company, which describes its customers as smarter and better looking than those of its giant competitor in its press releases, debuted its 2501 appliance last week at LinuxWorld Conference & Expo. The 2501 has nearly twice the horsepower (1.8 GHz versus 1 GHz) and more expansion slots than its 514 predecessor, which was introduced last March.

Although Cisco has overwhelming market share, Vyatta’s pitch is its eye-popping price advantage (it’s about a tenth of Cisco’s cost). In addition, the functionality of Vyatta’s router is in software, which is easy to upgrade, versus Cisco’s proprietary hardware boxes, which can only be upgraded via replacement.

Rob Whiteley, the principal analyst at Forrester Research Inc. in Cambridge, Mass., said the new router is better and more powerful than its predecessor and would enable Vyatta to go after more than the low-hanging fruit of small companies and branch offices.

The 2501, in contrast, has the additional processing power and throughput required for medium to large networks and could function as a link to a wide area network (WAN) or a security appliance.

Vyatta will never be large enough to meet all of most companies’ needs, Whiteley said. But the growing acceptance of open source products and the current budget-shrinking economy should help Vyatta’s cause, he said. Ultimately, Vyatta’s success will depend on its ability to offer additional services along with its routers, he said.

Red Hat previews virtual management tool

At a mid-morning session during the Red Hat Summit in Boston today, a standing-room only crowd of more than 125 attendees got a preview of oVirt, a “next-generation open source virtualization management solution.”

Currently in beta, oVirt comprises two components: oVirt Managed Node, which is an embedded hypervisor based on a Linux kernel and KVM; and oVirt Server Suite, an administrative console that includes a Web interface and has functionality for tasks related to virtual machine management, such as status monitoring, performance monitoring and visualization and authentication.

With oVirt, IT administrators get a picture of “what’s going on in your server room from a virtualization perspective,” said Red Hat CTO Brian Stevens. The current generation of virtualization management tools, contends Stevens, fall short for customers because they are proprietary and do not integrate into the enterprise.

The oVirt infrastructure integrates with several open source projects, including libvirt for virtual machine management, FreeIPA for directory services, Cobbler and Koan for provisioning, and collectd for performance data collection.

Currently oVirt enables IT administrations to collect data from managed hosts; eventually Stevens said that oVirt will include automation capabilities to allow IT administrators to establish service-level agreements around physical and virtual machines and migrate machines accordingly based on those levels.

Partnering up for a showdown? Red Hat Summit 2008

This post was contributed jointly by SearchEnterpriseLinux editors Lauren S. Horwitz and Caroline Hunter

As the VAR Guy noted in a recent blog post on the upcoming Red Hat Summit, Red Hat has some gumption. The Raleigh, N.C.-based company has crossed the Mason-Dixon line to hold its annual event in Boston, the territory of its rival, Waltham, Mass-based Novell: What chutzpah!

Not to be outshined, Novell has made its presence known, posting some conspicuous advertising in the Hynes Convention Center, the location for this year’s Red Hat Summit, the VAR Guy reported.

But whether Red Hat’s choice of venue is a real shot across the bow or not, there’s little doubt that that over the past several years, the Red Hat/Novell rivalry has gotten pretty heated. One could date the boiling tensions to 2006, when Novell signed an agreement with Microsoft to share product patents. In 2007, the two companies agreed to work toward interoperability and have even dedicated a lab to that purpose.

By joining forces, Microsoft and Novell aim to gain an even stronger foothold in the open source market, though some data indicates that both the Red Hat and Ubuntu distributions have made strides against Novell SUSE. A new survey on open source adoption may support these findings.

The VAR Guy also noted Cisco’s expected prominence at the Summit and wondered whether it might signal an upcoming Cisco/Red Hat partnership, much like Microsoft’s with Novell. Or maybe Cisco’s “cozying up,” as the VAR Guy characterized it, is more a case of “The enemy of my enemy is my friend.” Consider this user comment in response to the Var Guy’s musings:

“Cisco now views Microsoft as its #1 threat in unified communications and other areas,” the user wrote. “I think they are just solidly placing themselves on the other side to be honest. They see a cost/competitive advantage and want to help set the ‘other’ standard.”

Stay tuned from the frontlines for more Red Hat Summit coverage.

Does Linux kernel 2.6.23 break VMware Server?

First, there was the great iPhone 1.11 update bricking debacle. Today, it’s the great Linux kernel 2.6.23 conspiracy?

Admittedly, that doesn’t quite roll off the tongue as well as an iPhone story. That said, I think the implications for today’s revelations about 2.6.23 are far more important to the tech community than some gadget-of-the-moment touch screen phone could ever hope to be.

Andrew Kutz, blogging for our sister site SearchServerVirtualization.com, claimed today that the 2.6.23 release of the Linux kernel breaks VMware Server while at the same time boosts the street cred of Xen and KVM, or Kernel-based Virtual Machine.

[T]he new Linux Kernel, 2.6.23 was released on 2007/10/09. The latest product of the world’s greatest hackers includes a bevy of new features, including increased support for Xen and KVM, two open-source virtualization solutions. Users of those products are probably very happy today, eagerly awaiting the adoption of the new kernel by their favorite distribution in order to take advantage of the increased guest support that comes with it. VMware Server users on the other hand are getting the proverbial shaft. Kernel 2.6.23 has one MAJOR change and one minor change that completely break VMware Server.

I’m not as up to speed on VMware and its relation to the Linux kernel as I ought to be, but Kurtz’s post brought me up to speed pretty quickly. Apparently, fixes for the two problems are not easily executed, which kind of leaves this whole issue flapping in the wind.

Then again, maybe that was the idea, Kurtz waxes hypothetically: “perhaps most interesting of all is the timing. The same Kernel that provides extended support for Xen and KVM also breaks VMware Server. Coincidence? Like I said, I try to air on the side of optimism. How about you?”

I’m a cynical optimist, and I know how important Xen and KVM are in the open source community. I guess that leaves me “undecided” on this issue. What say you?
