Abstract: A system for authorizing a serverless application function having a plurality of tenants, each tenant may include one or more entities that share a common access to a processing space and a data store. The system includes a gateway that receives a request from a tenant, an authorization component that access a public key assigned to the tenant, and a serverless processor that generates public and private keys for the tenant. The serverless processor also generates an access token for the first tenant that is signed using the private key and requests a transaction token from the authorization component using the access token. The authorization component transmits a transaction token to the serverless processor, which is used to make further requests to a virtual environment.
