The Virtualization Practice

Citrix have released XenClient v2.0, their second generation bare-metal client hypervisor. XenClient allows centrally managed virtual desktops to run directly on corporate laptops, even when they are disconnected from the network. This version is intended to add ease-of-use and scalability features, and introduce a wider hardware compatibility list. In addition Citrix also launched the new XenClient XT, a standalone product designed to give advanced levels of security, isolation and performance for organisations with very specific and unique client computing requirements.

Less than 5% of the applications that matter to enterprises world wide are under management by an APM solution that can help ensure application response time, application availability and the integrity of the critical transactions within the application. This is because first generation APM solutions have been too expensive to purchase, too limited in their scope and too expensive to configure, maintain and own.

VMworld EMEA, IPExpo, The ExecEvent, Citrix Synergy, oh my!

This month (October 2011) there are a slew of conferences on virtualization and cloud technologies being held in Europe. The question becomes which to attend! If you are in the United States, this could be expensive considering the current Euro to Dollar exchange rate but if you are already in Europe one of these events is well worth attending, each has there own take and focus. But after the success of VMworld US, is there anything more to announce?

Whether you are building a new or adding to an existing virtual or cloud environment on a shoestring budget, whether for work or for home use, there is quite a bit to consider before you purchase anything and it all boils down to your requirements which will dictate the technology you need for your virtual environment. In addition, this is a perfect time to address any deficiencies in your environment to not only address capacity issues, requirements, and security. Along with those considerations, planning the environment for the next three to five years can help shape the overall design. In fact that design, will be based on the answers from a growing list of questions.

Whether or not to put data into the cloud has been a debate since clouds were first formed. At a recent conference I was asked:

with all the security issues you brought up, why should I go to the cloud, I do not know the administrators, nor can I gain cloud visibility, so why go to the cloud at all? and if so which cloud?

There are a myriad of reasons to go to the cloud, not the least of which is politics or being told to go to the cloud. When the real question is:

which cloud services is my organization already using and how can I gain control over the data being placed into the cloud.

Cloud Performance – Learning from SalesForce.com

The focus upon sharing real response time and transaction load data by SalesForce.com is notable when compared with the pre-historic approach to performance that is used by many cloud vendors (and for a matter of fact many enterprise IT organizations). Response Time correlates directly to end user experience and at the end of the day that is all that matters. Hopefully the industry will learn from SalesForce.com and advance this concept further.

Link your Clouds using AFORE Cloudlink

AFORE Solutions has created AFORE Cloudlink, which won the Best of VMworld for Security at VMworld 2011 in the United States. Yet, many people were scratching their head saying, who are AFORE and why did they win. AFORE moved from a physical appliance to a virtual appliance about 3 years ago providing a way to move data between data centers in an encrypted fashion, which at the time was desperately needed. After three years they have made quite a few changes, but still have their core functionality, but now included data at rest encryption and the ability to stretch layer-2 and layer-3 networks between locations amongst others.

On 9/22 was held the Virtualization Security Podcast featuring Anil Karmel, Solutions Architect at Los Alamos National Library (LANL), to discuss their implementation of secure multi-tenant Cloud. LANL makes extensive use of the entire VMware product suite from vCloud Director down to the vShield components to implement their SMT cloud. They have also added into their cloud their own intellectual property to improve overall cloud security. It was a very interesting conversation about the state of SMT today.
