In part four, I will explain all the concepts you need to know before we deploy ElasticSearch in the
communities, Kluster ElasticSearch will be where our log's will get started.
So first, I will explain briefly what ElasticSearch is and why we're using it in our setup.
We're going to deploy multiple replicas of ElasticSearch, and since it's a stateful application, we
will replicate it using stateful set component.
So I will also explain briefly what stateful said component is and how it compares to deployment component
in order to make our lives and ElasticSearch deployment easier.
We're going to use Helme charts.
So I'm also going to explain what Helme is and what Helme charts are and how they make application deployment
easier in communities.
