As part of a large scale data analysis project I was working on recently I used Horizon View and Instant clones to allow me to deploy hundreds of VMs based on my original templated VM which had my app I wanted to use to take in the data, transform it and then return a result. Its important to note that this app was never written to work in a batch mode, it literally took one input and gave an output based on a number of factors.
Whilst this post is not about the benefits of Instant Clones, let me tell you, once I had the original template VM working correctly and optimized for performance it worked like a charm, there is something to be said for the simplicity and efficiency of instant clones and the memory sharing techniques it uses to be able to run hundreds of essentially the same VM.
Once I had these VMs deployed via Horizon I could easily send a job to each VM and tell it to run the job, as these jobs however took an indeterminate amount of time to crunch the data, I needed a way to monitor them and let me know when all the jobs had finished on all the VMs so I could pull the data to analyze it.
