ELK (Elasticsearch Logstash Kibana)

Though we're focused more on server setup procedure in this document, I will still give a very brief explanation in laymen terms for ELK. To those who are starting new in this stack, must have already heard of MVC (Model View Controller), so take it like this:

• Model => Elasticsearch (for Storage, Indexing & Search)
• View => Kibana (for DataViz & G-Man, yeah the one in half life 😏)
• Controller => Logstash (For Logs & Filtering)
