I would like to use a single VM to host a SPLUNK license master and deployment server. Can one instances of SPLUNK on the VM act as both the license server/master and the deployment server? Do both license manager and deployment server use port 8089? What resources (CPU, RAM, Disk) for this type of setup?
I am using a single instance Deployment server/License master (AWS server in cloud). Since its a single instance configured to perform two jobs, they use same management port. Mine is very low configuration and works just fine.
CPU - 1 Core, 1.7 GHz RAM - 4 GB HDD - 100 GB (never utilized fully so can be downgraded)
See if this helps.
