Introduction

On November 11, 2025, during KubeCon North America, the Cloud Native Computing Foundation (CNCF) announced the global availability of the Certified Cloud Native Platform Engineer (CNPE) certification.

As with all CNCF Certifications, before the official launch, there’s a beta tester release. The idea is that people with skills and backgrounds aligned with the certifications take the exam before the global launch to analyze difficulty, question comprehension, and even find bugs or issues with the environment or exam questions.

Introduction

For those unfamiliar, the Kubestronaut Program is a CNCF initiative that recognizes individuals who have passed all 5 available Kubernetes certifications.

My Journey

Before discussing my Kubestronaut journey, I’d like to briefly talk about my journey with Kubernetes.

I’ve been working with Kubernetes for approximately 6 years, so I had a solid foundation for most certifications.

My Journey with Kubernetes

I’ve worked with Kubernetes in bare metal, Azure, AWS, and OpenShift implementations, across Banking, Telecommunications, E-commerce, Logistics, and Food industries.

As we have seen lately, Crossplane took over the world of Platform Engineering providing an absolutely easy and powerful way to build cloud native control planes.

But how does it work? How can I use it? What are the gains?

This brief post, which is created to be the initial one for a Crossplane series, aims to answer some basic questions for those who are still eager to use it.

This article was born from initial studies about Fluent Bit. It’s basically my understanding of the official documentation with some examples of simple use cases.

What is Fluent Bit?

Fluent Bit is an open source and multi-platform Swiss knife for logs processing and distribution.

Nowadays data comes from various sources and Fluent Bit is here to help you aggregate and process all your data in a reliable, secure and flexible way.
