Editor
Copy, cut, paste and image export
Move parts of a diagram around, and export the canvas as PNG or SVG.
Site
Home, pricing, learn and tools pages
With real editor screenshots and figures you can click.
Power as a failure domain
Utility feeds, UPSs, PDUs, generators and batteries now take part in the failure test.
Utility feed
UPS
Server
up on battery down
Power
Power links and power cuts
Draw supplier to consumer, then cut the power for a set time and see what stays up.
Power
UPS runtime and overload trips
A UPS carries its load for its rated runtime. A supplier loaded past its rating trips.

Cable from a free jack to a free jack, drawn as faceplates.
Catalog
UPS, PDU, generator and battery catalog
Hundreds of models with their rated power and runtimes.

The first release: draw it, then test it
An infrastructure canvas with an analysis engine behind it.
Zone
Rack
Server
Container
A node is down when anything around it is down.
App in zone Azone lost
App in zone Btakes the traffic
The line marks what the app can serve. Past it, the cluster is not N+1.
Editor
Zones, racks, servers and software
Containment is the failure domain: a node is down if anything around it is down.
Analysis
Single points of failure
What a traffic source can still reach after one thing fails, and after any two.
Analysis
Quorum and redundancy
A cluster that loses its majority stops serving, even the members still alive.
Analysis
Traffic, bandwidth and latency
Requests propagate through the design, including failover load.
Analysis
Capacity
RAID, host fit, racks and runway.
Analysis
Availability
Exact bounds over simultaneous failures, and a seeded simulation when the bounds are wide.
