Can you explain why ELK stack is used in projects?

The ELK stack consists of three components: Elasticsearch, Logstash, and Kibana. It is used for centralized collection, storage, analysis, and visualization of logs and other data.

• Elasticsearch — a search engine and database optimized for fast searches and aggregations.
• Logstash — a tool for collecting, filtering, and transmitting data from various sources to Elasticsearch.
• Kibana — a web interface for visualizing and analyzing data from Elasticsearch.

In ELK projects, it helps quickly find errors, analyze system behavior, monitor performance, and generate reports, which is especially important for supporting and developing complex applications.
