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.

=Getting a Cloud project=
* If you do not have a Compute Canada account, create one with [https://www.computecanada.ca/research-portal/account-management/apply-for-an-account/ these instructions].
* If you are a primary investigator (PI) with an active cloud resource allocation (see [https://www.computecanada.ca/research-portal/accessing-resources/resource-allocation-competitions/ RAC]) you should already have a project. If not or you are not sure please contact [[Technical support|technical support]].
* Otherwise go [https://docs.google.com/forms/d/e/1FAIpQLSeU_BoRk5cEz3AvVLf3e9yZJq-OvcFCQ-mg7p4AWXmUkd5rTw/viewform here] to:
** request access to an existing project
** and if you are a PI you may also:
*** request a new project with our Rapid Access Service ([[Cloud_RAS_Allocations|RAS]])
*** or an increase in quota of an existing project.
Requests are typically processed within two business days.
==Preparing your request==
* When requesting access to an existing project you will need to know the project name and type (compute or persistent). See the section on [[OpenStack#Projects|projects]] for guidance on how to find this information. In addition these requests for access must be confirmed by the PI owning the project.
* When requesting either a new project or an increase in quota for an existing project some justification, in the form of a few sentences, is required:
**Why you need cloud resources
**Why an HPC cluster is not suitable
**Your plans for efficient usage of your resources
**Your plans for maintenance and security ([[Security_considerations_when_running_a_VM|refer to this page]])
*A PI may own up to 3 projects, but the sum of all project quotas must be within the [[Cloud_RAS_Allocations|RAS]] allocation limits. A PI may have both compute and persistent cloud RAS allocations.

* Getting an account and an allocation:
* Login to one of the clouds below where you have a [[OpenStack#Projects|project]]. Authenticate using your Compute Canada (CCDB) credentials.
** If you do not have a Compute Canada account, create one with [https://www.computecanada.ca/research-portal/account-management/apply-for-an-account/ these instructions].

** If you or your sponsor do not have a cloud resource allocation (see [https://www.computecanada.ca/research-portal/accessing-resources/resource-allocation-competitions/ RAC]), use our [[Cloud_RAS_Allocations|Rapid Access Service]].
