Well, It may solve the issue with ES. But it is pricy solution. Small instance of ES can handle it same and I can even have multiple of them (cheper ones) and it would be good.
Since I use it just for web searches, I am not interested in Kibana, etc... Yes, it is nice tool. But not must-have I would say. curl is powerfull either and few scripts does health-check on self-hosted ES the same as any other solution
