Implementation feasibility

Are you willing to collaborate with us to discuss the solution, decide on the approach, and assist with the implementation?

• Yes, I am able to implement the feature and create a pull request.

We developed a version that is SaaS compatible and has TenantID associated with each deployment.
TenantID is:

• part of all primary stack names and exported variables.
• added as environment variable to all code projects
• cognito user pool has the TenantId in the name and also users have now TenantId attribute
• all lambda functions have TenantId in their environment variables
