Environment booking request catalog item or custom application

[UjjwalJ]

Is there any feature or application/module in ServiceNow that supports environment booking request form for monthly releases or environment booking where we have multiple applications like servicenow, splunk etc and testing team needs to reserve environment. How can we handle such situation or scenarios and if there is any custom application available?

I'm not aware of any environment booking paradigm OOB, but sounds like a fun feature to build.
Assuming you already have the environments articulated in your CMDB, you'd need another table to store booking records.  It would have to be a separate table from the CMDB class since there could be multiple simultaneous requests for different times... OR a request made for the same time slot that someone has to reconcile.
