Elasticsearch administration training

Course overview

This course focus on administration, operations, of an elasticsearch cluster. Install, deploy, monitor, setup and performance tuning. You will learn administration tasks as well: security patch, version upgrade, backup, add or remove nodes, install plugins.

We will focus on security: howto and core principles.

You will learn how to size your cluster and follow best practices.
