With cloud options available for both Elasticsearch and Splunk these days difficulty of setup / ease of use may be better evaluated from the client perspective. I’ve setup both ES and Splunk in the past few years and it’s not terribly different at lower end scale (< 100 GB logs / mo). But currently Splunk is not as good as ELK for metrics and vice verse and with the recent SignalFX acquisition that may change in a couple years but it definitely isn’t now. Also, there’s tons of options for streaming logs to ES besides Logstash including Filebeat which is at least written in Go (Splunk’s forwarders are probably in C given I swear they’ve been mostly the same since the early 2000s).
