Quotas
Service quotas, also referred to as limits, are the maximum number of service resources or operations for your AWS account.
Quotas for AWS services in this solution
Make sure you have sufficient quota for each of the services implemented in this solution. For more information, see AWS service quotas.
Use the following links to go to the page for that service. To view the service quotas for all AWS services in the documentation without switching pages, view the information in the Service endpoints and quotas page in the PDF instead.
AWS CloudFormation quotas
Your AWS account has AWS CloudFormation quotas that you should be aware of when launching the stack in this solution. By understanding these quotas, you can avoid limitation errors that would prevent you from deploying this solution successfully. For more information, see AWS CloudFormation quotas in the in the AWS CloudFormation User’s Guide.
Resource limits within the solution
Research Service Workbench on AWS imposes limits on some resources within the solution.
Users per project
Within Amazon Cognito, a user can belong to up to 100 groups. Users within RSW can only belong to 100 projects as either a Project Admin or Researcher. This is a hard limit.
Projects
User pools within Amazon Cognito can only contain 10,000 groups. Therefore, only 4,999 projects can be created in RSW. Each project creates two groups—Project Admin and Researcher groups. IT Admin is another group within the RSW deployment. This is a hard limit.
SSH keys
Within EC2, a single account can have 5,000 key pairs per Region. There can be no more than 5,000 active SSH keys in RSW. Each SSH key is backed by a key pair and scoped to the Region in which RSW is deployed. This is a hard limit.
Environments
Research Service Workbench on AWS groups and adds metadata and attributes to resources using AWS App Registry applications. With App Registry, Research Service Workbench organizes resources and tracks dependencies more efficiently. RSW associatess every resource to an App Registry application including all workspaces. App Registry currently has a default limit of 1000 resources per application.
If you are estimating to create more than 999 environments in your Research Service Workbench instance, a service quota increase will be needed. Follow these steps to request a quota increase for App Registry application resources:
-
Sign in to your Hosting Account in the AWS Management Console
. -
Open the Service Quotas console
. -
Go to Service Catalog and choose Service Catalog from the results.
-
Under Services Quota, choose Resources per application.
-
On the Resources per application page, choose Request Quota Increase under Recent quota increase requests.
-
In Change quota, enter your estimated number of workspaces plus one for an infrastructure resource.
-
Choose Request.
Hosting accounts
The solution has a limit of 403 hosting accounts.
