A simple network architecture design based on layered approach.
Architecture#
Here’s a typical layered achitecture design, with DMZ and Backend networks, and connected via firewalls.
%%{init: {'theme': 'forest'}}%%
flowchart TD
%% Nodes
Internet("fa:fa-globe Internet")
Firewall1("fa:fa-shield Firewall")
DMZ["DMZ Network"]
Firewall2("fa:fa-shield Firewall")
Backend["Backend Network"]
DNS("fa:fa-server DNS Server")
Web("fa:fa-server WEB Server")
AppServer("fa:fa-server App Server")
Database("fa:fa-database Database")
%% Grouping nodes in Subgraphs
subgraph DMZ
DNS
Web
end
subgraph Backend
AppServer
Database
end
%% Edge connections between nodes
Internet --> Firewall1 --> DMZ
DMZ --> Firewall2 --> Backend
Network Diagram#
This is a network diagram that based on the architecture above.
%%{init: {'theme': 'forest'}}%%
graph TB
External("fa:fa-globe Internet/cloud")
FW{{"fa:fa-shield Enterprise FW"}}
subgraph Backend [DC Backend]
direction LR
AppSvr(("fa:fa-server App Server"))
DBSvr1[("fa:fa-database Database")]
DBSvr2[("fa:fa-database Database")]
DBSvr1 ~~~ AppSvr ~~~ DBSvr2
end
subgraph office
direction TB
ITOPS("fa:fa-user IT Ops")
Users("fa:fa-users Users")
Users ~~~ ITOPS
end
subgraph DMZ
direction TB
DNS("fa:fa-server DNS_Server")
WEB("fa:fa-server WEB_Server")
DNS ~~~ WEB
end
subgraph DC [Data Center]
direction LR
FW <---> DMZ
office ---> FW
end
External <---> DC <---> Backend
Both diagrams are created with
