Problem
Modern cloud-native environments generate massive volumes of telemetry data (metrics, events, logs, and traces) with high cardinality, making it difficult and expensive to monitor application performance effectively. Traditional monitoring tools struggle to handle this data deluge, leading to sluggish dashboards, unreliable alerts, and ultimately, increased operational costs.
Solution
Last9 provides a telemetry data platform designed for high-cardinality observability at scale. By integrating metrics, events, logs, and traces into a single interface, Last9 enables teams to monitor and alert on application performance without the typical burdens of cardinality explosion. The platform offers features like client-side data manipulation, optimized cardinality workflows, and accelerated queries to ensure granular insights without crippling monitoring systems. Last9's control plane provides a developer experience for managing data, configurations, and lifecycle, including access control, usage understanding, and routing path definitions.
Target Audience
Last9 targets Site Reliability Engineering (SRE) teams, DevOps engineers, and platform engineers who need to monitor and optimize the performance of cloud-native applications at scale.
