• No on premises or self hosted option

Elastic Observability:

• Self hosted deployment with full data control
• Elastic Cloud managed option available
• Hybrid deployment possible
• Full compliance with data residency requirements

This is the most significant difference. Last9 is SaaS only, which means telemetry data leaves your infrastructure. Elastic Observability can run entirely self hosted, keeping all data inside your VPC or data center. For regulated industries or teams with strict data residency requirements, Elastic’s self hosted option is essential.

Search and Query Experience

Last9:

• SLO focused dashboards with fast filters
• Pre-built queries for common use cases
• Limited custom query language

Elastic Observability:

• Elasticsearch Query DSL for full query control
• Kibana UI with custom dashboard creation
