Coordinate Web, App & DB Tiers
Sequence a multi-layer rollout.
Real Apps Have Layers
A typical stack splits into tiers: web servers, app servers and a database. Each tier has its own role and its own deploy order. 🏗️
Order Matters
You usually bring up the database first, then the app, then the web tier. Configuring layers out of order breaks the rollout.
