Scaling and configuring Sitecore Identity Server
The Sitecore Identity Server (SIS) role is based on the Duende IdentityServer framework and used to request and handle identity, grant access, and refresh tokens.
Installation
Use the Sitecore Installation Framework (SIF) or the Sitecore Azure Toolkit (SAT) to install the SIS role. Refer to the installation guide for your version of the platform for more information.
Scaling the Sitecore Identity Server role
The following table describes the ways you can scale the Sitecore Identity Server (SIS) role:

|

Yes |
You can deploy the SIS role as a standalone role. |

You cannot set up multiple instances of the SIS role behind a load balancer. An encrypted cookie can only be decrypted by the specific instance of the SIS role that originally issued it, which cannot be guaranteed in a load balanced setup. |
