AWS PCS 2 NIC vs 3 NIC - differences?

[rampulse]

Hi PCS Users,

Brand new to PCS, about to do my first deployment onto AWS. I'm having trouble identifying the differences between the 2 NIC and 3 NIC deployment of PCS into AWS? It seems to me the only real difference is having a MGMT NIC on a separate subnet, but that has no impact to the end user experience. Is this correct?

3 NIC : https://aws.amazon.com/marketplace/pp/B07KX8SBJM

Thank you,

Yes, that is correct – the third interface is management interface.

When the management port is enabled, the following traffic is directed out the management port: archiving (FTP/SCP), NSM, NTP, push config, SNMP, syslog.

When the management port is not enabled, that traffic uses the internal port: some organizations prefer to use a separate management network, which is when you would need the 3-NIC version.
