IBM Instana Observability is a full-stack observability and application performance monitoring platform. It discovers and instruments applications and infrastructure automatically, maps dependencies in real time, and uses smart alerts and AI-assisted investigation to reduce noise and manual work. It integrates with the OpenTelemetry Collector and extends to AI agent and LLM observability. Instana can be purchased as SaaS, as a self-hosted installation or on a pay-per-use basis. It is not open source.
Instana was founded in 2015 in Solingen, Germany, and IBM announced its acquisition in November 2020. It now belongs to IBM, a US company, so US jurisdiction, including the CLOUD Act, applies to the vendor. In April 2026 IBM added an Instana SaaS region on AWS in Frankfurt (eu-central-1), which lets European customers keep observability data within the EU. The self-hosted option allows operation in infrastructure of the customer's choosing. Check the current list of SaaS regions in the Instana documentation before deciding.
