Elastic Stack

Introduction
The components that build up the data-driven architecture of Elastic (ELK) Stack are:
 * Kibana: explore and visualize data
 * Elasticsearch: store, index, search and analyze data
 * Logstash: enrich and transport data to Elasticsearch
 * Beats: collect, parse and ship data to Logstash or Elasticsearch
