AWS server migration/scaleup (debian)
I’m using AWS (EC2) for a lot of my work at the moment, I generally run things out of a microinstance, however sometimes I need to scaleup to a larger system to run something computationally intensive. I’m using debian, and this is the script I’m currently using to do this. You’ll need to setup euca-tools, and have .eucarc files for the regions you want to use, but this might help point you in the right direction:
