VDI Printing. Is it the Nemesis it was for Terminal Services? Part I

All the News That’s Fit to Print” is the motto of the The New York Times . Despite a proliferation of devices that allow you to take content with you wherever you go, despite e-mail, despite services like LinkedIn, Podio and Twitter there is still a driving demand  to generate hard copies of documents.

Printing is so common and fundamental that it is often overlooked as an IT service when migrating to virtualised desktops. How do your users connect to the printers they have? In fact, what printers do they use? What are the printer drivers and settings that are common or unique? Continue reading VDI Printing. Is it the Nemesis it was for Terminal Services? Part I

CloudFoundry Apps not VMs

VMware’s latest effort, CloudFoundry, is not about VMware delving into the PaaS market even deeper. They have done that already with VMforce. CloudFoundry on the other hand is a fairly astute move to enable the development and rapid adoption of cloud based applications.  The end goal is to sell what makes up a PaaS environment which is more enabling software. This would enable enterprises and businesses to move to the cloud. The problem with them moving now is that there are not that many applications that are cloud friendly. In effect more concentration on the application and less on the operating system which has always been VMware’s strategic direction. Continue reading CloudFoundry Apps not VMs

OpenCompute – Facebook drives Data Center and Cloud evolution

Traditionally, internet companies like  Google consider their custom server and data center designs as proprietary knowledge that creates significant value, but last week Facebook (which had previously bought commodity servers and rented data center space) has opened up a whole new area of Open Source technology by publishing the full specification of both its new custom server and its new data center as “Open Source” at OpenCompute.org.

Facebook’s designs aim to reduce capital costs by removing unnecessary components from the server and the data center, and by simplifying manufacture and construction.  They also seek to reduce running costs by increasing the efficiency of power usage. Although the initiative has been “Greenwashed”, reductions in power consumption seems primarily motivated by saving cost, not saving the planet.

Virtualization Performance Management – Linking Response Time, Load and Chargeback

In Applications Performance Equals Response Time, not Resource Utilization, we took the position that while for the majority of the applications deployed on physical hardware the general practice was to infer their performance by looking at normal vs. abnormal resource utilization statistics, once you virtualize an application, it becomes necessary to directly measure its response time in order to ensure adequate service to business constituents and end users.  Continue reading Virtualization Performance Management – Linking Response Time, Load and Chargeback

Ericom’s HTML5 client for VMware View

I have to admit that it came as a bit of a surprise to see Ericom beating Citrix, VMware, et al to the punch last week by shipping the beta release of its HTML5-based RDP client, before any of the bigger vendors opened up their offerings to public scrutiny. I’ll be looking at the operation of Ericom’s HTML5 client in more depth next week, but first we need to understand why anyone would be interested in deploying a HTML5-based remote desktop client at all. Continue reading Ericom’s HTML5 client for VMware View

Harris Trusted Cloud – Closing the Gap

On the 4/7/2011 Virtualization Security Podcast, we were joined by Wyatt Starnes of Harris Corporation. Wyatt is the Vice President of Advanced Concepts of Cyber Integrated Solutions at Harris. What this means, is that Wyatt is one of the key folks of the Harris Trusted Cloud initiative. Trust is a funny word, and we have written about that in the past.

Figure 1: Trust Chain of Integrity

Harris’ approach is unique in that they are attempting to ensure integrity of all components of the cloud down to the code level, not just the network with their target being the hosted private cloud and NOT the secure multi-tenant public cloud.

Granted their approach could be used for a Secure Multi-Tenant Public Cloud, and I feel will be required for such a cloud to exist. So what is their approach? It all starts with a company Harris bought a while back: SignaCert which is a different approach to what Tripwire does today (as Wyatt Starnes was an original founder of Tripwire). SignaCert has an ever growing database of software signatures. The software signature gathering component and process becomes part of the supply chain for all components into the Harris Trusted Cloud.  These components include signatures for routers, switches, operating systems, and applications which are generated as close to the software release process as possible.
