Serverless Fraud Detection

This is an example of how to use a Viridian Serverless cluster as a fast cache for static data that is used by an AWS Lambda function to contextualize transactions and detect fraud.

Internal Hazelcast Developers

If you want to try this tutorial in the UAT or DEV environment, edit the hazelcast.js file to include the following settings:

let createClientConfig = () => {
    return {
        network: {
            ...
            },
            ssl: {
                ...
                sslOptions: {
                    ...
                    // Otherwise the client will throw an error
                    // because the cluster's hostname doesn't match the one
                    // in the self-signed TLS certificate.
                    checkServerIdentity: () => null
                }
            }
        },
        properties: {
            // For DEV, use https://test.dev.hazelcast.cloud
            'hazelcast.client.cloud.url': 'https://uat.hazelcast.cloud',
            ...
        }
    }
};
