Very appreciated by web startups, the Elastic or Stack ELK Suite is composed of 3 open source Big Data solutions: Elasticsearch, Logstash and Kibana.
- The NoSQL Elasticsearch database is a complement to Hadoop. It allows you to store, search and analyze your mass data stored in Hadoop. It indexes strongly text-oriented documents. It is like a search engine that can be configured to match your exact search needs in real time.
- ETL Logstash allows you to process data. Like a server-side pipeline, it ingests data from various sources, transforms it, formats it and sends it to Elasticseach.
- As for the Kibana dashboard, it allows you to visualize your data with tables and graphs in Elasticseach.
