Hi Suhas,
Hope you are doing good.
There is no special requirement to deploy SSO in cloud environment other than hardening your Cloud environment/servers and enabling secured access to the On-Premise Userstore/agents, if any.
There is no ready-made script available to setup SSO environment as every customer environment/requirement is unique. However I am sharing here my colleague Alan_Baugher's KB article which has got working scripts along with very well explained deck which will enable you to get started for your deployment.
DEV-OPS: CA Identity Manager & CA SSO - CLI Silent Response Scripts on Centos7
Please let me know, if you run into any issues. Happy to assist you.
Regards
Ashok
