AWS Code to Custom Cloud Architecture Diagrams

In my last blog, I wrote about how to generate code to custom cloud architecture diagrams using the Diagrams tool .This is an extension to the previous blog, where I have created a similar code and diagram representation for Google Cloud DevOp process.

Here is the custom diagram representation of AWS devOps process

The process was part of the AWS devOps blogs

The code to generate the above diagram is given below

from diagrams import Cluster, Diagram, Edge
from diagrams.custom import Custom

graph_attr = {
    "fontsize": "12",
    "bgcolor": "white",

with Diagram("AWS", show=True, graph_attr=graph_attr,direction="LR"):

    developer  = Custom("","./my_aws_extensions/developer.png")

    operationsApproval  = Custom("","./my_aws_extensions/operations-approval.png")

    with Cluster("AWS", graph_attr=graph_attr):

            sourceRepo  = Custom("","./my_aws_extensions/aws-code-commit.png")

            commitEvent  = Custom("","./my_aws_extensions/aws-cloud-watch-event.png")

            ciBuild  = Custom("","./my_aws_extensions/aws-code-build.png")

            ciDeploy  = Custom("","./my_aws_extensions/aws-cloud-deploy.png")

            ciProdDeploy  = Custom("","./my_aws_extensions/aws-cloud-deploy.png")

            buildArtifact  = Custom("","./my_aws_extensions/aws-s3-build-artifact.png")
            pipeline  = Custom("","./my_aws_extensions/aws-code-pipeline.png")
            sourceRepo >> Edge(label="event") >> commitEvent

            commitEvent >> Edge(label="trigger") >> pipeline

            #with Cluster("AWS Pipeline", graph_attr=graph_attr):
            with Cluster("", graph_attr=graph_attr,direction="TB"):
                customBuildTest  = Custom("","./my_aws_extensions/custom-build-test.png")

                devDeploy  = Custom("","./my_aws_extensions/custom-dev-deploy.png")

                prodDeploy  = Custom("","./my_aws_extensions/custom-prod-deploy.png")

            customBuildTest >> Edge(label="pass") >> devDeploy

            devDeploy >> Edge(label="pass") >> prodDeploy

            pipeline >> customBuildTest

            customBuildTest >> Edge(label="trigger build") >> ciBuild

            ciBuild >> Edge(label="store artifacts") >> buildArtifact

            with Cluster("VPC Dev", graph_attr=graph_attr):
                stagingCluster  = Custom("","./my_aws_extensions/stage-cluster.png")

            with Cluster("VPC Prod", graph_attr=graph_attr):
                productionCluster  = Custom("","./my_aws_extensions/production-cluster.png")

            stagingCluster << Edge(label="fetch artifact") << buildArtifact

            devDeploy >> Edge(label="trigger deploy") >> ciDeploy

            ciDeploy >> Edge(label="deploy artifact") >> stagingCluster

            prodDeploy >> ciProdDeploy

            ciProdDeploy >> Edge(label="deploy artifact") >> productionCluster

            productionCluster << Edge(label="fetch artifact") << buildArtifact

    operationsApproval >> Edge(label="Approval") >> prodDeploy 

    developer >> Edge(label="commit") >> sourceRepo

CI/CD and Build optimization – Top 5 Strategy

Having a optimized build and CI/CD process results in faster, efficient and cost effective builds.

Here are Top 5 things to start with for CI/CD optimization –

  1. Build Lean Container Images – Separate building the application from building its runtime layer and build form minimal base images  Reference –
  2. Using a cache like Kaniko with your build to cache container build artifacts .Kaniko works with all major cloud container registry. Reference –
  3.  Selective deployment based on last run and changes – Reference –
  4.  Exclude files not required by build using vendor supported .ignore files – Reference – ( For docker, refer to BuildKit and .dockerignore , Link – )
  5.  Move towards Green devOps – Understand the carbon impact of your builds and  schedule – batch changes for build, leverage green regions and timelines.
