Traditional logging is broken for modern microservices. Scattering disconnected string logs across distributed systems leads to context fragmentation and expensive telemetry bills. This technical guide explains how to transition from legacy log statements to Wide Events and Tail Sampling. Learn how high-cardinality, high-dimensionality event records restore visibility and cut storage overhead. #Observability #DevOps #SRE #Logging #DistributedSystems #OpenTelemetry #WideEvents #FinOps #Backend
Traditional Kubernetes autoscaling relies on CPU and memory metrics, leading to laggy workloads and expensive over-provisioning. This technical guide explains how to leverage KEDA (Kubernetes Event-driven Autoscaling) to scale your deployments dynamically based on real-time event cues—including scaling to absolute zero to slash cloud infrastructure costs. #KEDA #Kubernetes #CloudNative #Autoscaling #DevOps #SRE #FinOps #AWS #PlatformEngineering #RabbitMQ #Prometheus
