Virtual machines can be easily replicated. One can take a "snapshot" of a VM which can then be started again elsewhere. This makes it easy to replicate or scale up a service, and to recover from (for example) a power interruption. | Virtual machines can be easily replicated.

Is the cloud the right place for your work? If you can fit your work easily into the [https://en.wikipedia.org/wiki/Supercomputer HPC] [https://en.wikipedia.org/wiki/Batch_processing batch] submission work flow and environment (see [[What is a scheduler?]]) it is likely a better solution, as there are more [https://www.computecanada.ca/research-portal/national-services/compute/ resources available] for HPC. It is also possible to use tools like [[Singularity]] to run custom software stacks inside containers within Compute Canada HPC clusters. | Is the cloud the right place for your work?
