Getting Data In

Sending data with HEC vs modular inputs vs raw port

I'm trying to figure out the pros and cons of using each of these methods to send data to Splunk. Let's assume I have full control over the data, so I can send it in any format.

To the best of my understanding:
HEC: push data to Spunk via Splunk's REST API
Modular input: a script (?) that runs on the Splunk side, good for pulling data from external REST APIs
Open port: (https://docs.splunk.com/Documentation/Splunk/7.3.0/Data/Monitornetworkports) send arbitrary data over a raw port for Splunk to index, and the indexing can be configured on the Splunk end

What other considerations should I be keeping in mind when deciding between these approaches? Any limitations to be aware of?

Thanks!

Don't use network ports. you get no load balancing etc. HEC is HTTP post (web hook) meant to be web load balanced. Modular inputs usually you run on a heavy forwarder so you have to plan to have a backup of all inputs etc in case the box dies and you have to rebuild it.
