🔍 OpenTelemetry Observability

Read. Think. Ship. Repeat. Your innovations deserve the best infrastructure insights.

64% of users find AI tools actually lighten the workload, yet 59% roll their eyes at the hype—function outshines flash. But behind the curtain, data prep still plays villain, tripping up 24% of AI builders.

Amazon EKS now powers IPv6 dual-stack VPC clusters. It doles out /80 prefixes via the VPC CNI flags ENABLE_V6_EGRESS and ENABLE_V4_EGRESS.  AWS ships an Istio multi-cluster playbook—single-VPC to multi-VPC. It rigs remote reader secrets and east-west gateways, fusing IPv4 and IPv6 for service discovery and routing.

Meet the GKE Inference Gateway—a swaggering rebel changing the way you deploy LLMs. It waves goodbye to basic load balancers, opting instead for AI-savvy routing. What does it do best? Turbocharge your throughput with nimble KV Cache management. Throw in some NVIDIA L4 GPUs and Google's model artistry, and scaling those gnarly generative AI workloads becomes a breeze. No bottleneck sweating necessary.

OpenTelemetry delivers a full observability package for Kubernetes—traces, metrics, logs—all without handcuffs to a single vendor. Deploy your own OTEL Collectors on Minikube using Helm charts. Dive into node and pod-level metrics and grab those can't-miss Kubernetes cluster events.

Migrating Pinterest's search infrastructure to Kubernetes—toasty, right? But it tripped over a rare hiccup: sluggish 5-second latencies. The culprit? cAdvisor, overzealously spying on memory like a helicopter parent. Flicking off WSS? Problem evaporated.

EKS Hybrid Nodes corrals on-prem and edge servers as remote Kubernetes nodes over Direct Connect or VPN. It rides on Cilium or Calico, with BGP or static routes. For local load balancing, it spins up MetalLB at Layer 2/3. For NLB/ALB sync, it taps the AWS Load Balancer Controller. Workflows stay unified.

Fluent Operator taps CRDs to tame Fluent Bit in Kubernetes. It channels inputs, filters, parsers, outputs into auto-generated configs. Then spins up the DaemonSet. The Fluent Bit Watcher wrapper hot-swaps configs on CRD tweaks. No pods restart.

Kong offers three different helm charts for Kubernetes ingress, leveraging the new Gateway API. Kong Gateway Operator simplifies deployment and management by using CRDs instead of custom helm charts. Using GatewayClass and Gateway resources are essential for the operator to spin up dataplanes and control planes seamlessly.
