THE DESIGN & IMPLEMENTATION OF SPRITES

fly.io12 min read

Summary from the TLDR Dev newsletter

Sprites is a platform of Linux virtual machines. These Sprites offer instant creation (1-2 seconds), root access, 100GB of durable storage, and automatically sleep during inactivity. Their unique capabilities come from certain design decisions: eliminating user-facing container images, using S3-compatible object storage for persistent disks, and using an "inside-out orchestration" model where much of the management occurs within the VM itself.
