Elasticsearch 7 and Elastic Stack - In Depth and Hands On! - Introducing Logstash

Logstash is a powerful tool for data processing, acting as a bridge between data sources and destinations like Elasticsearch. It can import data from various sources, transform it, and export it to multiple destinations. Logstash can structure unstructured data, filter, and anonymize it, ensuring legal compliance. It also offers buffering capabilities to manage data spikes and guarantees at least once delivery. Modern usage involves integrating with Filebeat for efficient data handling, while legacy methods involve direct use on servers. The ELK stack has evolved into the Elastic stack, emphasizing the Beats framework.
