News: latest Login VSI 3.7 gets Windows 8, Windows 2012 and Oracle VDI support

Login VSI B.V. have announced the availability of Login VSI 3.7, the latest version of the performance and scalability testing tool for Virtual Desktop Infrastructures and Server Based Computing environments.

This latest release means that Login VSI 3.7 has out-of-the-box support for simulating user workloads to test the performance of VDI and SBC environments based on Windows 8, Windows Server 2012 and Microsoft Office 2013. In addition, Login VSI also introduces support for Oracle Virtual Desktop Infrastructure.

Eucalyptus/Terracotta a scalable Java Cloud Platform?

We have a series of posts (SpringSource/VMware, 3Tera, Eucalyptus, Hadoop/Cloudera…) about the application directly targeting a distributed virtual machine which is abstracting over the virtualization layer and/or operating system. Essentially these are targeted at those who are building or adapting applications for the cloud, rather than starting from the premise of a virtualization of existing infrastructures.

It must be said there is no clear model yet emerging for how you do this. The 3Tera solution is slick and allows you to define your infrastructure at a logical (application) level and grow or shrink your architecture graphically on commodity hardware, but ultimately there are limits to the horizontal scalability of the layers in the architecture that comprise your application.  When we last looked at Eucalyptus it was driving in a similar direction with packaged VMs and its own scalable filesystem  but wasn’t really dealing with the tiers of an application as logical entities.

We recently received a presentation on a combined solution from Eucalyptus and Terracotta. Initially we were suspicious because they clearly share an investor – Benchmark Capital.  Was this a PowerPoint integration dreamt up by two Venture Capitalists over a power breakfast?  However, the combined solution was presented by some very plausible techies with a real-live demo and does look as though it starts to provide a generally-useful abstraction over which to deploy scalable applications (specifically Java stacks), and it too works with commodity hardware.  It’s not as slick as the 3Tera solution, more of a command-line approach, but it potentially has the edge in scalability.
