# Solution Overview

Solution for Centralized Network Inspection on AWS.



# Architecture Diagram

![Architecture Diagram](./source/architecture.png)



## 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 /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.
