Cloud Architecture Diagram Generator
Quick Start:
Choose cloud provider → Declare stencil icons → Group into VPC/region zones → Connect with arrow syntax → Wrap in
plantuml
fence.
⚠️
IMPORTANT:
Always useplantuml
or
puml
code fence. NEVER usetext
— it will NOT render as a diagram.
Critical Rules
Every diagram starts with
@startuml
and ends with
@enduml
Use
left to right direction
for typical cloud architectures (data flows left→right)
Use
mxgraph.
stencil syntax for cloud service icons
Default colors are applied automatically — you do NOT need to specify
fillColor
or
strokeColor
Use
rectangle "VPC" { ... }
or
package "Region" { ... }
for cloud containers
Use
cloud "Name" { ... }
for cloud boundary shapes
Directed flows use

, async/event-driven flows use
