Beyond the Collector: How the Open-Source Observability Stack Fits Together

What happens after telemetry leaves the OpenTelemetry Collector? Explore how Prometheus, Jaeger, OpenSearch, and Perses fit into an open-source observability stack, how to connect them, and what to consider before operating the stack in production.

Your telemetry doesn’t go straight to the backend: Understanding the OpenTelemetry Collector

The OpenTelemetry Collector helps you manage telemetry beyond application instrumentation. Learn how receivers, processors, and exporters work together, explore agent and gateway deployment patterns, and understand how to handle sensitive data, control telemetry volume, and improve pipeline reliability.

Native OpenTelemetry

OpenTelemetry has become the standard for generating telemetry in cloud-native systems, but instrumentation alone does not guarantee observability. This article explains the difference between OpenTelemetry-compatible and OpenTelemetry-native approaches, using a Kubernetes-based Minecraft example to show how transparency in the OpenTelemetry Collector and observability pipeline improves debugging, preserves context, and restores trust in telemetry data.

NeuVector for Kubernetes Security and Compliance

NeuVector delivers continuous vulnerability scanning and compliance enforcement across Kubernetes environments. This article explains how NeuVector updates CVE data daily, enforces admission control in discover, monitor, and protect modes, and automates CIS benchmark checks to secure workloads from build to runtime.

When Metrics Leak Secrets: Kubernetes CTF Lessons

In this blog, I’ll walk you through how I uncovered three hidden flags in a Kubernetes cluster by investigating Grafana, VictoriaMetrics, and VictoriaLogs. Each step highlights a different misconfiguration from weak secret management to metrics leaking sensitive data, to logs revealing too much detail. I’ll also highlight the security lessons learned so you know what to avoid in your own cloud native architecture.

Serverless Computing in Kubernetes: A Developer’s Guide

Deploy serverless functions with OpenFaaS on Kubernetes using Rancher. Learn setup, scaling, and cloud-native app workflows for modern development.

Microservices at Edge with K3s and Fleet

Learn how to deploy and manage microservices across thousands of edge locations using K3s and Rancher Fleet. This guide explores lightweight Kubernetes, GitOps, remote access, and serverless functions for modern edge computing.

Simplifying Microservices with Istio and Service Mesh Architecture

In this guide, we take a developer-first journey through Istio’s capabilities—sidecar proxies, WASM plugin customization, secure ingress and egress gateways, multi-cluster setups, zero-trust security with mTLS, and real-world traffic management patterns. Using a coffee shop microservices app as our example, we break down abstract concepts into digestible sections and hands-on examples.
