Elastic Stack is also referred to as ELK Stack based on the initials of its three components, which are Elasticsearch, Logstash and Kibana. While Elasticsearch works with the acquired data, Logstash provides aggregation and processing of data on the server side.
This makes it possible to receive data from multiple sources simultaneously and enrich it before indexing in Elasticsearch. Kibana, in turn, provides better visualisation and data management. It allows you to create not only common graphs and histograms, but also dynamic infographics or maps with visualisation of geospatial data.
