How Nest applies to real problems.
Every team that needs a database, storage, or a place to put streaming data usually means another tool, another vendor, and another queue to wait in — multiplied across every kind of data service a growing company needs.
On infrastructure shared across teams, one team’s data or network traffic can end up reachable by another’s if isolation depends on someone remembering to configure it correctly, every single time.
Teams that need some resources on infrastructure you run yourself and others directly in the cloud usually end up learning and maintaining a different process for each, slowing down both.
Backup coverage that depends on someone remembering to run a script, on a schedule that varies system to system, tends to have gaps — and those gaps are usually only discovered during a real incident.
Applications that were not built to spread read traffic across multiple database copies end up overloading a single instance, or need custom code written just to fix it.
Teams outgrowing Longhorn — a single-tenant, storage-only tool — often need team isolation, backups, and object storage it was never built to provide, but cannot accept a risky, all-at-once cutover to get there.
