CONTROL PLANE OPERATED INFRASTRUCTURE

Part 1: Introduction to Crossplane

This tech blog article introduces Crossplane, an open-source Kubernetes add-on that extends the capabilities of infrastructure management by leveraging Kubernetes as a control plane. Crossplane uses Kubernetes’ extensible API design and Custom Resource Definitions (CRDs) to manage not only services and applications but also cloud infrastructure. The article provides step-by-step instructions on how to get started with Crossplane and provision your first resources in the cloud using Kubernetes as a control plane.

Transitioning from Prometheus to OpenTelemetry - A Journey of a Cluster's Metrics Evolution

Part 1: A Brief Introduction

With this blog post, we kick off a series on evolving our Kubernetes metrics stack. Our journey to replace Prometheus with an OpenTelemetry solution begins with an introduction OpenTelemetry and why we see it as a valid alternative to our current implementation. After explaining the main parts of the OpenTelemetry project and briefly reviewing its history, we discuss the pros and cons. After reading this, you will be able to follow along our hands-on and deep-tech posts on how we optimize our metrics stack.

Transitioning from Prometheus to OpenTelemetry - A Journey of a Cluster's Metrics Evolution

Part 2: Scraping The First Metrics

Having explained the technical implementation of the monitoring stack in our latest blog post, this article focuses on replacing Prometheus with OpenTelemetry Collector to decouple scraping from the storage and query mechanisms. The OpenTelemetry Collector uses various building blocks to construct the telemetry pipeline and requires enabling of the target allocator. Guiding you through this process we provide various practical tips, including processor ordering and horizontal autoscaling."

Transitioning from Prometheus to OpenTelemetry - A Journey of a Cluster's Metrics Evolution

Part 3: Enabling annotation-based scraping

After showing how to get an OpenTelemetry Collector to support Prometheus CRDs as scrape targets, we discover how to integrate another well-known approach to mark workloads as scrape targets. Now, we focus on annotation-based scraping - what is it, when would we want to use it and how can we integrate it in our OpenTelemetry stack? In this article, we provide answers to all these questions, and more.
