Security of Performance and Management tools within the Virtual Environment

The problem is that not everything is as black and white as security folks desire. If we implement performance and other management tools, we often need to expose part of our all important virtualization management network to others. But how do we do this safely, securely, with minimal impact to usability? Why do we need to this is also another question. You just have to take one look at the Virtualization ASsessment TOolkit (Vasto) to realize the importance of this security requirement. But the question still exists, how do you implement other necessary tools within your virtual environment without impacting usability?

Federated Clouds? Possible?

Mike DiPetrillo’s post entitled VMware is Building Clouds sparked some interesting thoughts and discussion about what it means to have federated clouds and how do you define such federation? Is federated required to make ‘cloud’ ubiquitous or are we already there? But is the discussion really about federated clouds or simplistic data object movement between the VMs or about cloud management?

Cloud SLAs Are Worthless But Does this Matter?

A Service Level Agreement (SLA) is an excellent expectations-managing mechanism, but it’s important to manage your own expectations of what an SLA can realistically accomplish. Just those three words “Service” “Level” and “Agreement” is often an attention turn-off I know: SLAs are to infrastructure bods what documentation is to developers. Yet, when considering taking up cloud and utility services many consider that the SLAs offered aren’t reliable, if they exist at all. So the SLA becomes the blocker – ‘If I move services out of my data centre, how will I guarantee availability and performance’.

Technically, the Amazon Cloud didn’t actually fail

Amazon’s Service Level Agreement (SLA) is so narrowly-drawn that it could easily be argued that the recent Elastic Block Store (EBS) outage wasn’t a failure of Amazon Web Services at all. Anyone using EBS in a production environment was, arguably, reaping the fruits of their own folly. Of course they don’t tell you when you read the hype that architecting for resilience in the Cloud is actually very complicated, particularly if you want to take the sensible step of not relying on a single provider like Amazon, no-matter how dominant their hype may be.

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

VDI Printing. Is it the Nemesis it was with Presentation Virtualisation? We consider the core printing options for the likes of Citrix XenDesktop, Microsoft RDS, Quest vWorkspace and VMware View; and how they match to our printing considerations. We take an overview of solutions from ThinPrint, triCerat and UniPrint. An effective printing strategy must provide both the facility for printing to local printers as well as remote printing and include dedicated print server support. Ideally, you are in a better position to understand the cost of printing to your organisation: but don’t be surprised with incredulous looks when you tell user’s how much printing out their team meeting agenda cost.
