My name is Michael Hausenblas and I'm a product builder and OpenTelemetry practitioner. I want to help you implement Return on Investment Driven Observability using open standards, open source software, and open data including but not limited to OpenTelemetry and Prometheus.

I worked at Amazon Web Services (AWS) from 03/2019 to 04/2026 on Amazon Elastic Kubernetes Service, owned the AWS Distro for OpenTelemetry (ADOT), Amazon Managed Service for Prometheus, Amazon Managed Grafana, and in the Amazon CloudWatch service team I introduced OTel and PromQL support. From 2018 to 2022 I served as a Cloud Native Ambassador at the Cloud Native Computing Foundation (CNCF).

If you have observability-related questions or input please use mh9@bfield.cloud, reach out to me on the CNCF Slack, or DM me via Bluesky.

If you want to stay up to date on developments in the observability space, subscribe to o11y.news, my weekly ad-free and non-tracking newsletter:

Activities

Some of the books I authored and co-authored are:

2023.Cloud Observability in Action is a hands-on guide on applying observability in the context of cloud native environments using open standards and open source.

2022.Learning Modern Linux teaches modern Linux tooling and techniques.

2021.Hacking Kubernetes shows security defaults in action and how you can defend against attackers.

2019.Programming Kubernetes teaches you how to use and extend Kubernetes programmatically in Go. We cover low-level Kubernetes API access using the client-go package, custom controllers & resources, and custom API servers.
