Hi,
Is it possible to support more than 100 realms, by running keycloak in
high availability mode. Or there also we need to restrict the realms below
100?
Currently we are building a cloud based multitenant SAAS application in
which we are planning to use Keycloak for Identity and Access Management.
We thought of segregating
tenants using realm. If we proceed in this way, will that be a bottleneck
in future.
Thanks & Regards,
Vishnu Prakash
