OpenStack Basic Infrastructure

Basic OpenStack deployment with Neutron networking, Nova compute, Cinder block storage, and Swift object storage.

Key Elements

Component	Stencil
Router	mxgraph.openstack.neutron_router
Floating IP	mxgraph.openstack.neutron_floatingip
Security Group	mxgraph.openstack.neutron_securitygroup
VM (Nova)	mxgraph.openstack.nova_server
Volume (Cinder)	mxgraph.openstack.cinder_volume
Object Storage	mxgraph.openstack.swift_container

Example

@startuml
left to right direction

cloud "Internet" as internet

mxgraph.openstack.neutron_floatingip "Floating IP" as fip
mxgraph.openstack.neutron_router "Router" as router

rectangle "Internal Network" {
  rectangle "Subnet 10.0.0.0/24" {
    mxgraph.openstack.neutron_securitygroup "Security\nGroup" as sg
    mxgraph.openstack.nova_server "Web Server" as vm1
    mxgraph.openstack.nova_server "App Server" as vm2
  }
}

mxgraph.openstack.cinder_volume "Volume 1" as vol1
mxgraph.openstack.cinder_volume "Volume 2" as vol2
mxgraph.openstack.swift_container "Object\nStorage" as swift

Pattern Notes

1. OpenStack stencils: mxgraph.openstack.<service>_<resource> — e.g. neutron_router, nova_server, cinder_volume
2. Network hierarchy: Internal Network → Subnet as nested rectangles, Security Group inside subnet
3. Security Group links: ..> dashed to indicate security policy association
4. Storage outside network: Cinder volumes and Swift containers placed outside the network boundary
