The tour needs a desktop — it is mostly dragging things around, which is not a thing to attempt with a thumb.

Drag onto the canvas, or click to drop one in.

Components are vendor-free on purpose: a cache, not Redis. Put the specifics in the label and properties.

Press enter or space to select a node. You can then use the arrow keys to move the node around. Press delete to remove it and escape to cancel.

This is the canvas

A design is already on it: a browser, a load balancer, two app servers, and the address lookup both of them call. Everything here is live — drag things, rewire them, delete them.

Nothing in the tour is saved or scored. Reload the page and you are back to this.

Scenario

A small internal app behind a load balancer, which looks addresses up with an outside vendor. Nothing here is graded — this is the same canvas the real tasks use, with a design already on it so there is something to poke at.

Requirements

browsers reach the app at a single address
requests are spread across the app servers
if one server goes down, the app keeps answering

Constraints

nothing here is saved — reload and you are back at the start
