CLOUD / A CONCEPT NOTE
Managed vs Self-hosted
what you pay the cloud to worry about
Overview · mechanism
pitfall · examples
01 / THE SHORT VERSION
The idea in a few sentences.
Self-hosted means you buy servers and install, patch, and scale software (like databases) yourself. Managed (RDS, RDS Aurora) means the cloud handles patching, replication, and failovers.
02 / FOLLOW THE MECHANISM
How operation workload flows
Self-hosted deploy
developer launches virtual machine, installs Postgres, configures disk clusters, and scripts backups.
Managed deploy
operator clicks 'Create Database'. AWS provisions, replicates, and configures database in minutes.
Maintenance
cloud engine automatically updates minor versions and triggers failovers during outages.
04 / COMMAND NOTES
Read the command, then the result.
Inspect the flags and arguments before trying an example. Snippets can need local setup, replacement values, or resources in your own environment.

Could you explain Managed vs Self-hosted to a teammate?
Try it out loud in two sentences: what it is, and the one detail that changes the picture. If you stall, the gap is the part to reread.
