| Primary Function | Data collection, processing, and transformation | Data storage, search, and analytics |
| Work Environment | Part of the Elastic Stack, used for log and event data processing | Distributed search and analytics engine |
| Required Skills | Data pipeline, scripting, and log management | Search queries, data indexing, and cluster management |
Logstash and Elasticsearch are both key components of the Elastic Stack but serve different purposes. Logstash handles data collection and processing, while Elasticsearch stores and enables fast search and analysis of that data. They are often used together to build comprehensive logging and analytics solutions.
