Skills cloud

Create cloud provider architecture diagrams using PlantUML syntax with official AWS, Azure, GCP, and Alibaba Cloud service icons. Best for multi-service cloud topologies and migration blueprints.

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 use
```plantuml
or
```puml
code fence. NEVER use
```text
— 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" { ... }

package "Region" { ... }

for cloud containers

Use
```
cloud "Name" { ... }
```
for cloud boundary shapes
Directed flows use
```
-->
```
, async/event-driven flows use
```
..>
```
(dashed)

Full stencil reference: See stencils/README.md for 9500+ available icons.

Mxgraph Stencil Syntax

mxgraph.<provider>.<icon> "Label" as <alias>

Common Cloud Stencil Families

Family	Prefix	Typical Icons
AWS	`mxgraph.aws4.*`	`lambda_function` , `ec2` , `rds_instance` , `s3` , `api_gateway` , `cloudfront` , `dynamodb`
Azure	`mxgraph.azure.*`	`virtual_machine` , `azure_load_balancer` , `sql_database` , `azure_active_directory` , `storage`
GCP	`mxgraph.gcp2.*`	`compute_engine_2` , `cloud` , `process` , `repository` , `cloud_monitoring`
Alibaba	`mxgraph.alibaba_cloud.*`	`ecs_elastic_compute_service` , `slb_server_load_balancer_01` , `polardb` , `oss_object_storage_service`
IBM	`mxgraph.ibm_cloud.*`	`ibm-cloud--kubernetes-service` , `load-balancer--application` , `database--postgresql`
Kubernetes	`mxgraph.kubernetes.*`	`pod` , `svc` , `deploy` , `ing` , `sts` , `pvc` , `cm` , `secret`
OpenStack	`mxgraph.openstack.*`	`nova_server` , `neutron_router` , `cinder_volume` , `swift_container`

Connection Types

Syntax	Meaning	Use Case
`A --> B`	Solid arrow	Sync API call / data flow
`A ..> B`	Dashed arrow	Async event / trigger / replication
`A -- B`	Solid line, no arrow	Physical / bidirectional link
`A --> B : "label"`	Labeled connection	Describe the data flow

Quick Example

@startuml
left to right direction
mxgraph.aws4.users "Users" as users
mxgraph.aws4.cloudfront "CloudFront" as cf
mxgraph.aws4.application_load_balancer "ALB" as alb

rectangle "VPC" {
  mxgraph.aws4.ec2 "EC2" as ec2
  mxgraph.aws4.rds_instance "RDS" as rds
}

users --> cf
cf --> alb
alb --> ec2
ec2 --> rds
