Last week was very exciting for cloud computing. Citrix CloudStack provides the Apache Software Foundation to deliver what we heard our partners and customers demanding - an open source cloud computing platform ready for production that embraced the most permissive licenses and proven community more established in the world of open source. In responding to this market need, we believe that we have positioned CloudStack to become the leader in cloud computing platforms. While open source software is generally a disruptive technology with designs to trivialize a mature system owner or a legacy, this is one of the first times that I can remember where we see a disruption of technology is led to the adoption of open source and community development model. It is increasingly clear that open source systems will be among the biggest winners of the Cloud era.

To take advantage of this opportunity, vendors are falling over themselves to claim that they are open source. Provided washing clouds that passed in recent years, we are entering a stage where "open washing" became the norm. It's like a food product called "natural" (sorry to disappoint you, but just because Captain Crunch has fiber in it is not good for you). Without clear guidelines, all claims and counterclaims of suppliers, it is difficult for companies to understand how truly "open" technology is that they are encamped.

To help sort out the confusion, I put out "Three key questions to ask your 'open' Software Vendor" to get a better idea of ​​what they mean when they say their product is open source. We are not implying that there is only one way to do open source. After all, there are many successful models to provide technology in the open source leadership. It is important, however, that you understand what each provider, and the implications of their choices can have on you as someone buying or building on their product.

1. Under which open source license is the licensed product?

There are a number of open source licenses that have emerged over the last twenty years. Open source industry is littered with acronyms such as LPG, ASL, CDDL, BSD, etc. The most important thing for any customer or user to understand how these influential licenses on the various freedoms associated with open source communities. traditional copyleft licenses like GPLv2 and v3 have prospered under the Linux explosion over the last decade, becoming the standard license different distributions market. While the GPL was great for software like Linux programs, rules around the protection of IP and reciprocity have a less desirable license for many companies. In fact, many organizations have strict rules in place to where LPG can be deployed and managed in a corporate data center, especially to protect innovation and the internal IP development. As a result, more permissive licenses such as the Apache Software License, have taken center stage as the license of choice for cloud services built. These licenses have minimum limits on how the software can be distributed or used. While the Apache Software License offers the same freedom in terms of how the software can be used, its permissive structure allows wide innovation, deployment and distribution without any of the restrictions that come with copyleft licenses. In short, this means that customers are free to consume, distribute and innovate on the code without losing the intellectual property of the company. This elimination of risk has also become very attractive for ecosystem partners and developers who consider this model as a better way to engage in the development of the community.

2. How the project is governed?

Governance is one of the most important attributes of an open source project, because it defines much of the behavior in the project and in the community. There are two emerging models for open source projects :. 1) The governance of business and led 2) Foundation headed by governance

I remember an article I read some years back when I worked for Sun at the time OpenSolaris. Sun has been heavily criticized by Michael Dolan IBM in an article that criticized us for opening the supply of technology, but the maintenance of full property management and copyright of the project. In his post in 07:

"It is not for me to determine if any of the words to the current fashion today mingle company conducts open code projects under various licenses governance structures are "right" or "wrong," but I have a strong opinion that open source independent projects often have a head start in building communities, participation and multi-vendor investment (and often it is their goal). I also think it is foolish to expect a single company project in the trade should behave in a so other than a business driven by shareholders would be. "

As I look back on it today, I am reminded how Michael was correct focus in his statement. An open source driven in the trade that has direct links to a single corporation project is governed by a structure that is designed to benefit a person / organization - society. Guests looking for freedom of choice, lack of vendor lock-in and a genuine community engagement and innovation will want to align with a project that is aligned to share success, influence and directions all members of the group - not a single entity.

3. Can you access, study and deploy 100% of the commercial code, without any obligation to buy

"Basic Open vs Open Source" is a debate lively in the development community ?; with strong and polarized opinions if you find similar passions in this debate as you would around religion or politics. Many would argue that companies that follow the basic model open are companies open source at all, as all the "good things" that brings value to the product are held back under proprietary licenses and available only in a paid model. This distinction is important because the benefits of open that most companies still seek inaccessible in an open base model. Even in projects where the core could be completely open and delivered under a permissive license, if the packaging and delivery of added-value in the solution is not made available under the "freedoms" of the general open source, users not getting more benefit from the use of these technologies as they would with proprietary solutions.

the bottom line is there are many models of open source on the market and it is important for users to fully understand what freedoms they enjoy during engagement with specific projects. Our movement with CloudStack this week demonstrates the openness that we believe that these projects must be -. permissive licenses, contributors and foundations led governance with full transparency codes

Hey VMware, the sound you hear is the clock striking midnight. We enjoyed reading your blog lively today, but I would say the only thing you have in common with Cinderella is the fact that the image of the fantasy that you so carefully created evaporates before your eyes.

Unfortunately there is going to be a charming prince there to ride into the sunset with this time. People want to open. They want choice. Your request everyone using vSphere vCloud equals "choice" is like Henry Ford saying, "You can have any color of the car, as long as it is black." This is not to choose it is lock-in. one day, customers who choose your vCloud will wake up and find that they have been stuck with a vPumpkin.

Citrix XenClient team is very excited about our range at Citrix Summit (May 7 ^e - May 8 ^e ) and Citrix Synergy (May 9 ^e - May 11 ^e ) in San Francisco, CA! We demos, breakout sessions and more!

For those who do not know XenClient, it is a local virtual desktop solution that dramatically simplifies the management and security of laptops for customers who want to extend desktop virtualization benefits to users of laptop. The solution is more than just a client hypervisor. It really consists of two technologies - XenClient and Synchronizer for XenClient:

Citrix XenClient is a true type 1 client hypervisor that runs on bare metal and provides high performance and security. XenClient enables users to run multiple local virtual desktops simultaneously, side by side in complete isolation. Users fed XenClient laptops can access their various virtual desktops anywhere, anytime, even while disconnected from the network.

Citrix Synchronizer for XenClient enables laptops with XenClient to download virtual desktops centrally managed. Using Synchronizer, it may centralized backup of user data through a secure connection every time the user connects to the Internet, define security policies for managed laptops, disable lost XenClient laptops or stolen and restore virtual desktop to a user on a XenClient based laptop.

We have seen tremendous interest in XenClient and we look forward to presenting our latest developments with you! Our line of Citrix Summit

Our announcement on April 3 that we will submit CloudStack to the Apache Software Foundation has generated much of the fodder industry around open source - no surprise since we had 60+ industry partners supporting new door. And although the comments in the Twittersphere were heated at times, it is certainly a useful and necessary debate as we move into the cloud era. After all, the elevation of CloudStack into a full open source Apache project will only accelerate the delivery of a proven, powerful platform agnostic hypervisor that helps any construction customer real clouds Amazon style. But do not take my word for it, the always provocative Christian Reilly provides summaries of my favorite to date about why the news is important. And of course, this week there are many other conversations taking place at the Summit of the design and the OpenStack Conference. A cool session is checked via SlideShare "CloudStack + OpenStack - A Love Story" and Cloud.ca CloudOps

This week did better with the news that CloudStack was accepted into the Apache Incubator. . If you want to know more about the next steps of the project now that it's "official" visit the blog of Kevin Kluge for details. But in a word, we hope that the new community will bring a much more open process in decisions around CloudStack.

We are very pleased to announce a new member of the family AppFlow! The guys Lancope completed the initial integration with Citrix AppFlow, which collects Lancope flow NetScaler records. This initial integration with Lancope StealthWatch System provides advanced application availability monitoring functions, performance and security across physical and virtual environments.

With the initial integration, joint customers can easily draw AppFlow records of their Citrix NetScaler load balancers in StealthWatch for analysis and reporting. StealthWatch uses data from AppFlow to present statistics session of customers at NetScaler load balancer virtual IP, as well as show the statistics for the load balancer for appliances as a starting point for terminating traffic.

AppFlow Leveraging NetFlow and other flow data from existing devices, StealthWatch monitors the network and host behavior as a whole to establish baselines and early warning on a wide range anomalies.

Lancope also enhance integration with the full support of AppFlow records in future versions. This new integration with AppFlow Lancope will provide visibility and intelligence that gives customers additional data to get an overview of the traffic passing through their network at any given time at the application level.

The ability to analyze and correlate data streams from a multitude of devices allows organizations to get the levels of contextual awareness and actionable intelligence needed to better respond to network and security problems. Further details on this integration are in the memory of the solution, and will be available next week at the summit and Citrix Synergy 2011 in Barcelona. More information on the Lancope StealthWatch solution can be found here. And be sure to keep the appflow.org control updates on key integrations.

It has long been discussed when to go for a virtual desktop solution based on 1 or 2 vCPUs vCPUs. Well, it's not a rule, but I hope it can help shed some light for others.

I recently during a stress test for a client where the objectives were diversed, but I would like to highlight the result of running the same workloads with 1 vCPU and 2, with the same amount memory. . And how it greatly influenced the behavior of the boot storm

The test scenario was based on:

• 32 hosts Cisco UCS running VMware vSphere 4.1
• 00 virtual desktops provisioned with Provisioning services 5.6 SP1
• vDisk stores were CIFS based on NetApp boxes
• VM were :, 1 GB of RAM and 6GB PVS write caching on the base Windows XP SP3 virtual disk

with 1 vCPUs vitual based workstations, the entire infrastructure could, but in about 45 minutes , which under certain circunstances we were able to have after a storm starting around 00 unregistered virtual desktops when the infrastructure has reached its equilibrium state. Even refine the value of the Timeout startup services on virtual desktops.

With 2 vCPUs virtual desktops based, it started in 25 minutes , with 12 unregistered virtual desktops at the end cycling process

this result, I can say definitely, additional CPU will :.

• stimulate the diffusion / start process
• improve responsiveness and registration of virtual desktops
• with an increase in the cost of CPU hit the hypervisior

therefore, delivery will be:

• If you plan to go big with a huge number of virtual machines lifecycling every day ...
• If you have a large number of workstations that you might need to provide in advance ...
• If the window of your bike must be the shortest possible ...

... in any case, additional CPU will improve your cycling process, to reduce the gap virtual recording desktops with an additional cost of higher peak use of the host processor, improving your infrastructure availability.

I just take a look around the Expo Solutions and while some stands of sponsors still have the finishing touches put to them, it'll be a great area to catch up with the latest and our industry. It opens at 18:30 for our Synergy welcome reception this evening, so you have the opportunity to idea of ​​enjoying a well-earned drink and have a mooch around the Expo.

On the Citrix booth, you can take a close look at what we mean by "personal cloud", "private cloud" and "public cloud". There is a section dedicated to each of these, highlighting how Citrix technology allows anyone to work or play anywhere on any device

• personal cloud :. This section highlights the receiver and HDX on a variety of devices in different scenarios
• private cloud :. In this section, we will demonstrate the enterprise infrastructure needed to support a workforce increasingly tech-savvy. The gateways are evolving to be a network access point to the secure data center to become a single point of delivery for all enterprise resources both within the data center (such as desktops , applications and data) and outside (such as SaaS applications, Web applications, and even storage)
• public cloud. we will demonstrate the latest iteration of its infrastructure-as-a-service offers game changing that allow
  • in application delivery cloud
  • elastic computing multi-tenant
  • many other bells and whistles to enhance a cloud portfolio, including the recent acquisition Cloud.com

Similar to the genius bar at an Apple store Citrix has created a pavilion "Ask the experts" composed of experts of the Citrix Consulting services team. Located in the Citrix booth in Hall Expo, the pavilion will provide an overview of how the new Citrix technologies can be implemented more quickly and efficiently, technical answers to questions and ideas of best practice.

I will hopefully look forward to catching up with you all this evening!

Citrix today announced an end-user customer of the most exciting initiatives of its history. Since there were no new features or fresh demos, as an end user, you may not have noticed. Called HDX Ready System on a Chip (SoC), the initiative is not running exactly on the tongue so your lack of notice was not entirely unexpected. However, the impact of this initiative will soon be felt by all end users and IT alike!

Initially supported by Fujitsu, LG, Texas Instruments, Dell, Huawei, HP, Wyse, VXL, NComputing and DevonIT ​​with NComputing and Texas Instruments providing initial SoC reference design, this initiative has the potential to radically change and evolve the business office. By providing an integrated reference design for low cost HDX Ready capabilities, these partners - along with a long list of other providers who are not ready to attach quite yet their names - are exploring ways to create completely new endpoints and leverage design to create thin clients at considerably lower prices.

Unlike other protocols implementations in hardware, HDX Ready System-on-a-Chip is one of the reference models based on standards that are designed to track innovation in hardware and HDX. Other hardware technologies such as PCoIP-based cards are proprietary and expensive, and customers from strength to go through a major upgrade of the entire system to get the benefits of the latest innovations. HDX SoCs on the other hand, are reference models, standards-based HDX enhancements that offer both software and hardware. This intelligent design offers our customers flexibility to easily adopt new innovations HDX without going through an upgrade of major equipment.

To give you some ideas on what we're likely to see let me suggest that we talked to partners on creating HDX Ready displays, keyboards and even mice! In other words, you buy a screen or keyboard and all you have to do is plug it into a network enabled XenDesktop and HDX you get the full experience. While new form factors are interesting, we hope that the other side of the equation - the price equation - will have an equal or greater impact on the market. Citrix focuses on the dramatic reduction of the materials bill for HDX Ready systems. We believe that in a not too distant future, we can deliver reference designs that will cost our partners well below $ 50 to create and manufacture. This should clearly new clients HDX Ready that sell for under $ 100. Customers of the award will demolish the last barrier to mass adoption of virtual desktop.

More information on this initiative will be available in the coming months and will be one thing certain at this time next year the impact of this initiative will be seen positively by all Citrix customers and end users !

At Citrix Synergy Barcelona Mark Templeton described the new Citrix solutions Follow Me data. Built around the newly acquired ShareFile technology, which is now called, data Follow Me Fabric, Citrix will deliver three solutions that leverage the Citrix infrastructure to provide files and safely enterprise data for end users and improving collaboration work. Mark said explicitly in his speech that it was not a competitor DropBox but more like iCloud for the company. It was this comment that provides greater insight into the Citrix strategy.

DropBox, while a revolutionary cloud storage solution, remains undeniably precarious and largely unmanageable by IT companies. In contrast, the Citrix Follow Me Data Fabric is designed from the ground up to deliver the quintessence of IT management, security and control. Access to files and end-user data will be manageable, controllable and intelligent. IT will be able to determine which results can by synched, and accessed remotely. IT will be able to monitor, remotely wipe and define data and file restrictions for editing and local access / offline. Finally access will be intelligent. For example, if the end user is inside the secure network or working from a home PC, they can get full access to their records. Conversely, if they are outside of the work network, on the road or access to files from one device to the tablet, they can get more severe restrictions. Made even more end-user access can be allowed to file with their local publishing rights from a tablet within the network, but only access via a virtualized application to the outside the corporate network.

These capabilities represent a unique and highly differentiated cloud storage and access solution. Tied in Citrix Receiver IT will continue to manage authentication and access via the directory of groups and best practices. Anyway the ShareFile infrastructure and Follow Me Data Fabric represents the ultimate in managed IT data access.

During the next year expect the aspects of management and control of Follow Me data becomes an essential complement component Citrix CloudGateway solution management applications as well.
