Solution Overview

Solution for Centralized Network Inspection on AWS.

Architecture Diagram

Prerequisites for Customization

• Node.js>16

Build

Build the CDK code

cd source/
npm run build

Build the Centralized Network Inspection Solution CodeBuild source code

cd source/centralizedNetworkInspection
tsc 

Build the templates for custom deployments

cd deployments/
chmod +x ./build-s3-dist.sh
./build-s3-dist.sh [SOLUTION_DIST_BUCKET] centralized-network-inspection [VERSION_ID]

Unit Test

Run the unit tests

cd <rootDir>/deployment
chmod +x ./run-unit-tests.sh
./run-unit-tests.sh

Deploy

Follow the steps for deploying your custom version of the solution.

• Create an S3 bucket with the bucket appended with the region in which the deployment is to be made. example, if the deployment is to be made in us-east-1 create a bucket name as [BUCKET_NAME]-us-east-1.
• Create the distribution files using the script provided in the build section above.
• Create the S3 Key in the bucket centralized-network-inspection/[VERSION_ID]/
• Create the S3 Key in the bucket centralized-network-inspection/latest/
• Copy the file ./deployment/regional-s3-assets/centralized-network-inspection.zip to the location s3://[BUCKET_NAME]-[REGION]/centralized-network-inspection/[VERSION_ID]/
• Copy the file ./deployment/regional-s3-assets/centralized-network-inspection-configuration.zip to the location s3://[BUCKET_NAME]-[REGION]/centralized-network-inspection/latest/

Once the above steps are completed, use the file ./deployment/global-s3-assets/centralized-network-inspection-on-aws.template to create a stack in CloudFormation.

File structure

centralized-network-inspection-on-aws consists of:
