WHAT IS INTERACTIVE APPLICATION SECURITY TESTING (IAST)?

Interactive application security testing instruments running applications to find issues like SQL injection and XSS with fewer false positives. It suits QA and staging but needs runtime agents, adds overhead, and scales poorly across microservices, so mature programs pair it with SAST and SCA.

KUBELET WATCHES INODES. JUST NOT UNTIL IT'S AN EMERGENCY

Kubelet's background image garbage collection only monitors disk bytes, so workloads heavy on small files receive no early intervention before kubelet evicts pods. On one node, unpacked layers from a single-stage build containing the @mui/icons-material package consumed millions of inodes. A multi-stage Dockerfile can reduce the deployed image from more than 40,000 files to a few dozen. Adding a Prometheus alert for inode usage above 80% can catch the problem well before the 95% eviction threshold.

MONITOR WAREHOUSE DATA QUALITY BEYOND PIPELINE HEALTH

Pipeline success does not guarantee accurate warehouse data, so teams should add table, column, schema, and custom SQL checks with anomaly detection and thresholds. Lineage views trace issues upstream, and Datadog pairs Data Observability with Data Streams Monitoring for end-to-end coverage.

Shared worker hosts, power controllers, and USB hubs can turn one hardware failure into multiple broken CI jobs. Linaro's test-lab design gives each device a dedicated automation appliance and private network, with rollback-capable firmware to help keep the testing infrastructure reproducible and recoverable.
