When to use Elasticsearch?
ElasticSearch is a JSON database popular with log processing systems. For example, organizations often use ElasticSearch with logstash or filebeat to send web server logs, Windows events, Linux syslogs, and other data there. Then they use the Kibana web interface to query log events. All of this is important for cybersecurity, operations, etc.
How does Elastic Search work?
Elasticsearch uses a document-oriented approach when manipulating data which is stored in JSON format. Data can be organized and stored based on the index and type. There can be multiple indexes and types. You can think of the index as a database in regular relational database and type as tables.
Can I Elastic Search as my primary store?

Apparently, all the innovation around ElasticSearch is around improving resiliency.
How does Elasticsearch work?
Elasticsearch is a real-time distributed highly scalable and open source full-text search and analytics engine. It is accessible from RESTful web service interface and uses schema-less JSON documents to store data. Elasticsearch is completely document-based search instead of schemas and tables.
Does Elasticsearch is free or costly?

What is Elastic Search Engine?
Elasticsearch is a search engine based on the Lucene library. It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents.
What is Amazon Elasticsearch Service?
Amazon Elasticsearch Service (Amazon ES) is an Amazon Web Services product that allows developers to launch and operate Elasticsearch — an open-source, Java-based search and analytics engine — in the AWS cloud. Developers can use Elasticsearch in AWS to monitor cloud-based applications in real time and access log and clickstream analytics.
