This is referred to as the Elastic Stack, and Elasticsearch functionality in the stack is to store the data and make it searchable.
When dealing with multiple servers, and especially in a high availability environment handling logs can get quite complex. It can become difficult to debug with logs spread out over multiple servers and this is one of the problems that Logstash attempts to address.
