What is ELK?

Question

Could you explain ELK in simple words?

Answer 1

ELK stack is made up of Elasticsearch, Logstash, and Kibana open-source platforms. Each platform is a separate project offered by an elastic company, even though these are built to work together.

Elastic search is a distributed NoSQL database where we can store messages in JSON format. Search engines adapt elastic search for fast data extraction in less time.

Logstash is a collector that collects the data from different sources and streams data into the pipeline of processing events. After processing each event, it sends output to the Elastic search. 

Kibana is a visualization tool used to analyze by creating different graphs and dashboards from elastic search data.
