That's if you have a qualified sysadmin on-staff to manage it. We tried managing our own ES setup for a little over a year before giving up. Despite our simple needs and low traffic volume we regularly had difficult-to-diagnose issues with memory usage, node interconnectivity, and performance. With 3 EC2 nodes in a cluster we would occasionally have the cluster health go to yellow and remain in a 'recovering' sate indefinitely, bringing performance to a halt, and we'd essentially have to rebuild and swap the cluster.
Granted, none of us were proper ES admins, but we had a lot of experience working with system administration and specifically database performance and clustering. Despite that we were definitely in over our heads with ES.
