JBoss and rPath demonstrate choice and customization leading in Linux

This post was written by News Contributor, Pam Derringer.

Sometimes writing or reading tech stories about entirely different products can uncover new trends and ideas. I was intrigued with the JBoss Open Choice Java Application story last week because Red Hat officials said its new framework would enable customers to add specific functionality like clustering, caching, messaging and security in “microcontainers” or do without it, according to their needs.

In addition, for the first time, JBoss customers would be able to choose between three levels of application complexity, and move from one to another within the same management framework. By offering customers choice, JBoss will create major disruption in the Java application world, according to Aaron Darcy, JBoss product line director. Darcy added that customers are moving away from the bloated, one-size-fits-all applications that must contain code capable of doing everything, and opting for slimmer versions more tailored to their needs.

Darcy’s words struck a chord because last fall and again more recently, I wrote about rPath, a startup birthed by former Red Hat staffers who saw scaling problems with large deployments first-hand, and decided to solve the problem by upending the traditional all-purpose horizontal stack, creating a vertical, app-centric Linux-based stack with only the elements that a customized application needs to run. Obviously, rPath-constructed applications, too, are a lot slimmer than all-purpose counterparts. They are also a lot easier to maintain and update, saving time for IT operations staffs say rPath folks.

Although their approaches are somewhat different, the two companies are both reacting, it seems to me, to similar needs for more choice and customization rather than a hefty one-size-fits-all, “that’s all we offer” approach. Is this a trend that will reshape the software industry as we know it? What do you think?

Canonical, the sponsor of Ubuntu, today announced the simultaneous release of Ubuntu 9.04 Server Edition and the Ubuntu 9.04 Desktop Edition, available for download on Thursday, April 23, 2009, and the Ubuntu 9.04 Netbook Remix, available on Thursday April 30, 2009.

With the new 9.04 server edition, Canonical has worked to extend the range of enabled servers, with 45 of the most popular mid-range servers from IBM, Dell and Sun and HP tested in the Canonical labs.
Ubuntu 9.04 Server edition will preview Ubuntu Enterprise Cloud (UEC). Ubuntu is the first commercially-supported distribution to enable businesses to build cloud environments inside their firewalls. With Ubuntu 9.04 Server Edition, organizations can explore the benefits of cloud computing without the data or security issues associated with moving data to an external cloud provider. Following a successful beta program, Ubuntu Server Edition 9.04 will also be fully available on Amazon Elastic Compute Cloud (EC2).

Mark Shuttleworth, CEO, Canonical shared some of the server improvements in Ubuntu 9.04 Server edition include substantial improvements in some key applications for mail and other common infrastructure requirements.

“There has been an extension of work around suspend and resume of servers,” said Shuttleworth. “Amazon’s EC2 elastic computing meme will penetrate deeply into the enterprise. And organizations will want that same elastic computing internally, along with the power saving capability. The best method is suspending or resuming. Through effective use of elastic computing, we think we can greatly improve the energy savings in the data center.”

Shuttleworth referred to the concept of cloud computing as “the new hotness,” and says that Canonical has chosen to give it a very specific focus in this release. An image of Ubuntu 9.04 is now on EC2, so anyone interested in prototyping on Ubuntu 9.04 can fire it up on EC2. Shuttleworth shared that Canonical has a firm commitment to continue to release updates in the cloud. A description of other Ubuntu virtualization efforts and a more detailed report on the current position of Ubuntu in the data center and enterprise IT environment was published on SearchDataCenter.com at the beginning of April.

Ubuntu 9.04 Desktop Edition improves user experience
Mark Zimmerman, CTO, Canonical explained some of the new features in Ubuntu 9.04 Desktop Edition include a reduction in start-up time from 45 seconds to 25 seconds. According to Zimmerman, the release also includes an improved notification subsystem, which is the first in a series of design-led improvements.

“We are really working on improving the intrinsic experience of using Ubuntu on the desktop,” explained Zimmerman. “The notification subsystem has a standardized way of displaying [notices], that adds to the polished feel of the desktop.”

In addition, the desktop version of Ubuntu 9.04 features OpenOffice.org 3.0. This release of OpenOffice includes a lot of compatibility between Microsoft Office suite products that can make the user experience more seamless and easy, and wasn’t available at the last Ubuntu Desktop Edition release.

Data shows down economy spurs Linux adoption



Posted by: Leah Rosin

A Novell-sponsored IDC survey reveals a surge in the acquisition of Linux driven by the worldwide recession. More than half of the IT executives surveyed are planning to accelerate Linux adoption in 2009. If that’s not positive enough, more than 72% of respondents reported that they are either actively evaluating or have already decided to increase their adoption of Linux on the server in 2009, with more than 68% making the same claim for the desktop. The study surveyed more than 300 senior IT executives spanning manufacturing, financial services, and retail industries across the globe, as well as government agencies. The survey results are a good update to the fall 2008 Purchasing Intentions survey we conducted that hinted the economy would impact Linux adoption.

Linux has been gaining ground in the enterprise, as was seen with Red Hat’s impressive results from 2008. We said back in January that open source would do well in a down economy, and now there’s data to back up the prediction.

In the IDC survey, the leading reason given for migrating to Linux was an interest in lowering ongoing support costs. More than 40% of survey participants said they plan to deploy additional workloads on Linux over the next 12-24 months and 49% indicated Linux will be their primary server platform within five years. (Is anyone else surprised by that number?) Among those hesitant to adopt Linux, lack of application support and poor interoperability with Windows and other environments was cited as the primary concern, indicating the key areas that need more work. Companies have made great strides where interoperability is concerned, but clearly more work needs to be done before Linux can gain more ground. We have covered Red Hat’s recent interoperability agreement with Microsoft, Canonical’s effort’s toward certification on HP servers, and reviewed the leadership of Novell in interoperability efforts. But, clearly the market needs more assurance that Linux will meet their critical business needs.

Key to the recent interoperability efforts has been virtualization. This is a good move according to the survey results as nearly half of respondents stated that moving to virtualization is accelerating their adoption of Linux. A notably high, 88% of those surveyed plan to evaluate, deploy or increase their use of virtualization software within Linux operating systems over the next 12-24 months. An increase in virtualization uptake was seen in our 2008 Purchasing Intentions survey, which revealed that virtualization interest was influencing server purchases.

In our recent newsletter, we asked readers to tell us what’s missing from all of these agreements. We encourage you to share your thoughts here. What would you like to see in terms of specific application support or capabilities? What’s missing from the interoperability landscape?

Red Hat’s virtualization suite based on KVM



Posted by: Leah Rosin
Red Hat, Virtualization, Xen, KVM, RHEL 5.4, Linux security, performance, scalability

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.

Red Hat and Microsoft sign virtualization interoperability agreement

This morning I was sipping my coffee and browsing what my Twitter friends were saying, when I discovered some big news had been released today. Urged by customer demand and OEM concerns, Red Hat and Microsoft have announced a virtualization interoperability partnership. Matt Asay, a fellow Twitterer and blogger, pointed out that there would be a webcast at 11 EST, and with 15 minutes to spare, I got ready to get the details. Essentially, Red Hat has become a Microsoft Server Virtualization Validation Partner (SVVP), and Microsoft is now a Red Hat partner for virtualization interoperability and support. The basics of the agreement are outlined by Red Hat on their SVVP FAQ page.

Prior to the webcast this morning, a couple of bloggers had pointed out why this news was a little different than your run-of-the mill partnership. Their emphasis was strongly focused on the lack of patent agreements with the deal — a new turn of events for Microsoft and Red Hat after a few years of battling publicly over the topic.

On his CNET Blog, Asay shared his surprise and adulation of the maturing of both Microsoft and Red Hat to the needs of the market.

Today, Red Hat and Microsoft have together demonstrated that interoperability can exist independent of back-room dealings over patents. Microsoft has increasingly been forced to open its stance on patents by the European Commission, anyway, proving Red Hat’s resolute stance against patents was the right one. But today’s announcement suggests that Microsoft is maturing in its views as to how to interact with open-source vendors.

Asay pointed out that when Novell signed its agreement with Microsoft (in 2006), the announcement was met with criticism of the company from the open source community.

Asay’s Twitter post was a little more to the point (only 140 characters, afterall):

I guess this means, dear Novell, that in fact patent covenants need NOT be included in interop deals, including those with Microsoft

Matthew Aslett of the 451 Group posted a blog 15 minutes prior to the call, echoing Asay’s concerns.

In the webcast, Mike Evans, vice president of corporate development at Red Hat, and Mike Neil, general manager of virtualization strategy at Microsoft, tried to emphasize the customer-focused nature of the arrangement. Evans displayed statistics and sections of a recent IDC report on virtualization that proclaims we are only seeing the beginning of virtualization efforts in enterprise IT, and that more will begin to use the technology in 2009. These statistics match up with a recent survey conducted by SearchDataCenter.com that revealed that virtualization is on the rise in IT departments. In the call, a slide with a quote from Gary Chen, research manager of enterprise virtualization software at IDC, was displayed:

“IDC research shows that Windows and Red Hat Enterprise Linux are two of the main operating environments deployed by enterprises, accounting for 80% of the x86 operating systems running on hypervisors. It is great to see two of the big platform vendors put aside their competitive differences and put the customer first.”

Certainly, the effort is focused on the customer, but today, much of the focus seems to be skewed to the patent and financial language in the agreement. This seems fair, as the struggle between the two companies on the issue of patents has been publicly hashed out for almost three years. Microsoft had held fast to its claim that it couldn’t do interoperability without a patent pledge, but it looks as if Red Hat has won on its argument that a patent deal isn’t necessary to an interoperability agreement.

What do you think? Is this just another agreement? Or does this signify another change in Microsoft’s attitude toward open source collaboration? Or, have both companies just seen the writing on the wall and jumped just in time to take advantage of the virtualization market?

Red Hat proves value can be derived from open source

This week, Jim Whitehurst, president and CEO of Red Hat has issued a “State of the Union at Red Hat” message that at first glance appeared to be little more than a cute press pitch, well-timed with the State of the Union address from the President of the United States, Barack Obama. Whitehurst weaves in the common theme of open source being a “value” during the down economy, talks up acquisitions from 2008, and gives a shout-out to Linux community members JBoss.org and Fedora.

But things start to get interesting at point number six in his list, and I honestly would have missed this if I hadn’t seen the comments of The VAR Guy, who stated “Red Hat is destroying the old myth that there’s no money in open source.”

The VAR Guy’s declaration was based on Whitehurst’s statement with this information about the success of the company:

Weathering the economic storm. Red Hat has continued to execute well in what is a pretty competitive economic climate. In fiscal year 2008, Red Hat became the first open source vendor to cross the $500 million mark in revenues and we’ve also maintained 27 consecutive quarters of sequential growth in total revenue.

Impressive. Or is it? The VAR Guy points out that Microsoft earned 120 times as much during the same year.

Red Hat may be leading in the Linux distribution race thus far, but Novell is charging ahead, on the cusp of releasing SUSE 11, with greater virtualization and interoperability promised. With Novell’s partnership with Microsoft, the company is making gains in the market.

As businesses try to bounce back from the downturn in the economy, open source may be an even more attractive alternative. What do you think? Is Red Hat’s $500 million a true achievement, or is it just an attempt to give credence to open source? Share your thoughts.

Red Hat released version 5.3 of its Enterprise Linux distribution on Tuesday, about eight months after version 5.2. We gave an overview of the new features of the beta version of RHEL 5.3 in November. Now, it’s here. The new version offers enhanced virtualization scalability, OpenJDK functionality and Intel Nehalem processor support.

The company released a risk report comparing RHEL 5.2 to RHEL 5.3. Briefly, the report explains that 61 advisories were released to address the 181 vulnerabilities found in version 5.2. The seven critical advisories were for Firefox, Samba, and OpenSSH. The new version has all the updated security features, and the risk report shows that Red Hat saw fewer vulnerabilities with 5.2 than it did in 5.1 and 5.0.

The author of the risk report, Mark Cox, explains that “for Red Hat Enterprise Linux 5 since release and to date, every critical vulnerability has had an update to address it available from the Red Hat Network either the same day or the next calendar day after the issue was public.”

Let us know how your update goes — were there lags or glitches? What do you think about the new functionalities — are they useful in your enterprise? Is there more you want to see?

Open source to shine despite dim economy



Posted by: Leah Rosin
Open source applications, Cloud computing, Microsoft Windows, Vyatta, open source

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.

LAMP stack story overlooks impact of cloud, reader says



Posted by: Pam Derringer
Linux, Java, Development, Apache, Cloud computing, TechTarget Blogs, scripts, Linux blogs and news, Open source applications

My recent story on the dimming of the LAMP stack sparked a thoughtful reader response from John Locke, the manager of Seattle-based Freelock Computing. The story concluded that while an all-open source stack is still a valid concept, there are many more open source options that LAMP (Linux, Apache, MySQL and Perl, Python, PHP) is largely irrelevant.  I made a single exception for Apache, the popular Web server.

Locke argued, however, that even Apache has a growing array of alternatives such as the Lighttpd Web server, the Apache FastCGI Web interface,  the Nginx proxy server and others.

But what undercuts the LAMP stack more than the advent of additional open source options is the emergence of cloud frameworks, Locke said.

Initially, cloud computing meant renting compute power on demand from the likes of Amazon Elastic Compute Cloud (EC2). This meant renting a host virtual machine, programming the top layer, adding libraries and then when it was all done, managing the host and the virtual application, Locke said.

The problem with this model is that data centers are responsible for scaling the application up or down in response to changing volume requirements, he said. To solve this problem, Google, as well as Microsoft’s recently announced Azure platform, go beyond computing-on demand and manage the entire process with frameworks. All you do is write the application code (yes, you still need the P in LAMP), put it atop an application framework, and the framework will scale the application up and down as needed. No further involvement required. No LAMP stack required either.

Two successful examples of cloud frameworks are Salesforce.com and Facebook, he said.

The downside of frameworks, however, are loss of control and potential vendor lock-in, Locke said. The risk is less with Amazon EC2 since its controls are far more limited, he said. When writing an application for a specific vendor’s framework, however, a customer can lose portability because the provisioning and scaling mechanisms are behind-the-scenes and the source code and licensing are not necessarily readily available, he said.

The biggest challenge to LAMP as well as the Java and .NET stacks, therefore, is not the growth of additional choices but the cloud frameworks which may make all the stacks irrelevant. While handing over management and control is convenient, it also has its downside: you have to live by someone else’s rules, Locke said. Just  like a condo or regulated housing community, you’ve delegated the work, but you’ve also lost your freedom. Time will tell if you’ve made a good bet.

Don’t want to go to the cloud? Cassatt says to build your own



Posted by: Leah Rosin

You may be one of the data center administrators who’s heard the buzz about the cloud and has decided that it’s just hype. But the advantages of the cloud infrastructure are clear:

  • Extremely low operating costs (as low as 1/10 traditional IT costs)
  • Extremely high energy efficiency
  • Extremely low levels of complexity
  • High economies-of-scale
  • Metered billing (based on use); transparent costs
  • Other benefits of large data centers without owning capital

There are also a bundle of fears or disadvantages that are enough to keep many from jumping on board. Here are a few of Cassatt’s observations on what these are:

  • Security: infrastructure sits outside the enterprise’s walls
  • Service levels: Nascent model; agreements and levels unproven
  • Performance
  • Auditability and logging/traceability issues
  • Potential for cloud platform architecture “lock in”
  • Does not lower existing cost of installed capital or operations

In preparation for Cassatt’s internal cloud release this week, I talked to Ken Oestreich, director of product strategy, Steve Oberlin, chief scientist, and Jay Fry, VP of marketing at Cassatt. Oestreich explained how a product that the company had been developing for five years (initially referred to as its “utility computing product”) aligns with the cloud computing model. Essentially, Cassatt’s Active Response 5.2 allows you to turn your entire data center into a “cloud,” but without the disadvantages above.

“People who haven’t outsourced because of regulatory or security are not going to change,” said Oestreich. “They’re not going to a cloud.”

Seeing this opportunity, and realizing that many CIOs would love to take advantage of the efficiencies of the cloud but can’t afford the risk, Cassatt’s product allows users to get pretty close. Additionally, there are some advantages to the “internal cloud” model that include no platform-dependency issues and no “lock in” to an external cloud provider. Active Response 5.2 provides multi-platform support for Linux, Solaris, Windows and AIX; virtual machine support for VMware, Citrix (Xen) and Microsoft Hyper-V as adoption warrants; and networking support for Cisco, F5 and Force10.

In addition to Active Response 5.2, Cassatt has introduced its Active Profiling Service.

“Before you can embark on creating an internal cloud and merging application groups into pools that can share these resources, you have to know what you’ve got,” said Oberlin. “That’s what enables you to create a management strategy.”

Some consolidation planning software exists on the market, but Cassatt’s team thinks that it misses the mark and doesn’t provide users with all of the information they need. Cassatt points out that existing inventory tools don’t look at usage patterns, application dependencies or workload dynamics, and consolidation tools don’t consider workload management and server repurposing.

“A lot of companies today buy consolidation planning software if they’re doing virtualization. What this software doesn’t do is what all of our customers ask us about — provide a picture of the dynamics of the data center,” explained Oestreich. In order to manage a virtualized environment, it’s helpful to have an idea of “… which apps are quiescent and when, where the orphan servers are, where is virtualization appropriate and not, where is power management appropriate, and where is the internal cloud computing appropriate and not.”

Oberlin shared that the actual setup and implementation of the software can be rather rapid (a day or two). “The longest period of time is recording performance and utilization data to capture a reasonable business cycle to get a decent utilization profile of the applications over time,” said Oberlin.

The team envisions its internal cloud offering as something that users can gradually work into. I imagine dipping a toe in and then easing into the hot-tub and relaxing while the data center is efficiently managed.

  1. Analyze infrastructure and opportunities using Active Profiling Service
  2. Get started using policy management
  3. Take advantage of the power-management infrastructure and achieve increased energy efficiency
  4. Manage virtualization across multiple vendors , simplifying and automating virtual infrastructure
  5. Implement application availability across platforms and achieve greater operational efficiencies
  6. Implement resource repurposing across physical and virtual platforms and achieve greater capital efficiencies
  7. Meter infrastructure use, regardless of physical or virtual

In a time of budget cuts and reduced staffing in the data center, there’s no question that improved efficiency in physical and virtual machine management is beneficial. This type of move can help any data center prepare for future increased utility costs and trim down on new equipment provisioning. And who knows, maybe one day you’ll consider joining a community cloud.
