Resource isolation separates log traffic from critical business streams by placing logging on a dedicated Kafka cluster. This prevents high-volume log workloads from affecting latency-sensitive applications and permits each cluster to match its workload’s operational priorities. section 5.1.3
A dedicated logging cluster can be optimized for:
- Higher disk I/O throughput rather than low-latency storage. section 5.1.3
- Greater memory and network bandwidth for high log volume. section 5.1.3
- Different reliability priorities from financial or other critical business data. section 5.1.3
Separated log-processing flow
Applications send logs to Kafka; downstream processing indexes them in Elasticsearch and visualizes them in Kibana. Logging-system downtime need not stop producers or lose retained data. section 5.1.3
