IBM®, Instana®, is the gold-standard of incident prevention. It offers automated full-stack transparency, 1-second granularity, and 3-second notification. In today's highly complex and dynamic cloud environments, an hour of downtime could cost you six figures or more. Traditional application performance monitoring tools (APMs) are not fast enough to keep pace or comprehensive enough to contextualize issues identified. They are also typically only available to super users, who must undergo months of training. IBM Instana Observability is a solution that goes beyond traditional APM by democratizing observability. Anyone in DevOps or SRE, Platform Engineering, ITOps, and Development can access the data they need with the context needed. Instana delivers high-fidelity data with a 1-second granularity, and end-toend traces, as well as the context of logical, physical, and mobile dependencies, across applications, web, and infrastructure.

Integration Eye®, a modular product, streamlines system integrations, infrastructure and business. It is composed of three modules: the proxy module IPM and ILM logging modules ILM. The security module ISM can also be used separately or together. It is built on the secure, platform-independent Java language. Why choose Java? It runs on the Mule™ lightweight integration engine. You can monitor your APIs, systems, log calls, analyze them (logging with ILM module), and get alerted if there are any issues, downtime, slow responses to specific APIs or systems. You can secure your APIs using roles (authorizations and authentication with ISM module) based either on Keycloak SSO that we provide or your existing Auth server. You can extend and proxy service calls (both external and internal) using mutual SSL, headers, and other methods. These calls can be monitored and analysed via proxy with IPM.
