VictoriaMetrics Deployment and Practices: A High-Performance Alternative for Prometheus Long-Term Storage
Overview As the de facto standard for cloud-native monitoring, Prometheus has become the default choice for microservice and Kubernetes monitoring. However, as business scale grows, Prometheus’s local storage architecture increasingly exposes significant bottlenecks: limited single-machine storage capacity (default 15-day retention), no native horizontal scaling, memory spikes under high-cardinality scenarios, and difficulty querying historical data. Many teams find themselves facing the “triple dilemma” of disk IO pressure, storage cost inflation, and query latency growth once time series exceed the million-level mark....
