Elasticsearch is a distributed search and analytics engine that delivers high performance and scalability, even with very large volumes of data. It enables fast lookups and real-time analysis, making it well suited to demanding workloads such as application search, log analysis, and observability. Its cluster architecture optimises how data is indexed and put to use. On a dedicated server, Elasticsearch has exclusive access to CPU, memory, and storage resources, which means lower latency and consistent performance, while getting the full power and capacity of the software for mission-critical uses.
