Infrastructure Diagrams as Code

Veera26 — Sun, 21 Aug 2022 16:13:00 +0000

Diagrams are playing one of the major role in software development, Architecture development and Cloud infrastructure building.

This python package diagrams is really helpful to Software architect, Solutions architect, Cloud engineers and Enterprise architect to keep our infrastructure diagram as code

Benefits

Easy to understand
Help to simplify the process
Proper documentation
Versioning our infrastructure diagrams changes as code
Easy to customise
Open source

It's currently supports main major providers including: AWS, Azure, GCP, Kubernetes, Alibaba Cloud, Oracle Cloud etc... It also supports On-Premise nodes, SaaS and major Programming frameworks and languages

Installation

It requires python 3.6 version or heigher version python package


#using pip (pip3)
$ pip install diagrams

Quick start


# SampleDiagram.py

from diagrams import Diagram
from diagrams.aws.compute import EC2
from diagrams.aws.database import RDS
from diagrams.aws.network import ELB

#create diagram
with Diagram("Web Service", show=False):
    ELB("lb") >> EC2("web") >> RDS("userdb")



to run the above code in your terminal

$ python SampleDiagram.py

output

Example Clustered web service Infrastructure


#ClusterWebService.py

from diagrams import Cluster, Diagram
from diagrams.aws.compute import ECS, Lambda
from diagrams.aws.database import ElastiCache, RDS
from diagrams.aws.network import ELB, Route53
from diagrams.aws.integration import SQS
from diagrams.aws.storage import S3

#create diagram
with Diagram("Clustered Web Services", show=False):
    # route53  
    dns = Route53("dns")

    #Elastic load balancer
    lb = ELB("App load balancer")

    #Elastic containe service cluster
    with Cluster("Services"):
        svc_group = [ECS("service1"),
                     ECS("service2"),
                     ECS("service3")]

    #Simple queue service
    queue = SQS("SQS service")

    #Relational Database service db cluster
    with Cluster("RDS DB Cluster"):
        db_primary = RDS("userdb")
        db_primary - [RDS("backup")]

    #lambda functions cluster
    with Cluster("Lambdas"):
      handlers = [
          Lambda('Lambda 1'),
          Lambda('Lambda 2'),
          Lambda('Lambda 3'),
      ]

    #Elasticcache service
    memcached = ElastiCache("memcached")

    # S3 serive
    store = S3("File storage")

    #architecture work flow
    dns >> lb >> svc_group >> queue >> handlers
    handlers[0] >> memcached
    handlers[1] >> store
    handlers[2] >> db_primary

to run the code

$ python ClusterWebService.py
