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.

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 workflow and environment (see [[What is a scheduler?]]) it is preferable to work outside the cloud, as there are more [https://www.computecanada.ca/research-portal/national-services/compute/ resources available] for HPC and software is already configured and installed for many common needs. There are also tools like [[Singularity]] to run custom software stacks inside containers within Compute Canada HPC clusters.

If your need isn't served by singularity or HPC batch, then cloud is your solution.
