Old PC's + Old SBC's = Plebian Internal Cloud

This project is an internal cloud that is scaled enough to meet the demands of a single pleb like me.

Goals of this project

  • Learn how to use industry-standard DevOps tools
  • Try to adhere to Infrastructure as Code (IaC)
  • Give these old devices an actual use

These resources are dedicated to one purpose and one purpose only.

External Cloud Resources

Unfortunately, my internet connection is slow, so anything I want others to be able to use has to be hosted on an external cloud.

Management Utilities

  • Ansible — Declaratively configuring servers
  • Terraform — Declaratively provisioning resources

Things I no longer use

  • ELK Stack (Elasticsearch, Logstash, Kibana, Filebeat, Metricbeat) — This eats up a ridiculous amount of resources. As in, 6 GB (after attempts to minimize it) just dedicated to logging on a 28 GB cluster.

  1. Zerg rushing is essentially the “quantity-over-quality” tactic in strategy games: you send many expendable units against the enemy to hopefully overwhelm them.
  2. :thinking:
  3. This is my old laptop. I pulled it out of my backpack one day and saw the screen completely cracked for no good reason whatsoever.
  4. My mom complained about it being really slow, and even with Linux, it’s still slow. Thus, it’s worse than crap.
