Understand Systems with OpenTelemetry: A Hybrid Telemetry Data Backend - Ran Xu, Huawei & Xiaochun Yang, Northeastern University

HUAWEI CLOUD uses the cloud-native architecture to support thousands of services, DevOps requires understanding the running status of each system in a large number of interdependent microservices, middleware, and devices. openTelemetry is an observability industry standard. It provides standards and tools to generate high-quality telemetry data (metrics, logs, and traces). However, considering the need to quickly understand the system running status in massive telemetry data, a back-end storage that hybrid multiple types of telemetry data is a key part of the observability system. How to support efficient correlation query and real-time analysis in massive high-cardinality telemetry data and reduce the cost of telemetry data storage and computing is a challenge for us. In the sharing, we will introduce: 1. Key Challenges to Cloud Native Observability of HUAWEI CLOUD. 2. From metric data to telemetry data, the evolution history and thinking of observability back-end storage. 3. HUAWEI CLOUD observability cases.
