We run systems and write about them.

Pelindung Bumi is Rivaldo, Leo, and Rolando. We work with infrastructure, Kubernetes, cloud, and SRE — and write down anything worth remembering.

What we share

Infrastructure notes

Kubernetes basics

Cloud learning logs

SRE and DevOps lessons

Three engineers and their notes. We run into problems, figure them out, and write them down.
