title: Where to host logstash pipeline
body: <p>I am new to the ELK stack and heres my setup</p>
  <p>-&gt; backend with node js on heroku</p>
  <p>-&gt; mongodb database on atlas</p>
  <p>Now i am trying to sync my database (mongodb) with elastic search and figured out to use logstash as there is preprocessing involved.</p>
  <p>I choose aws opensearch aka managed elastic search but I don't know where logstash fits into the architecture is there any similar service for it or do i have to have to spin up an ec2 instance for logstash?</p>
