How can the migration progress be tracked using AWS Migration Hub in TypeScript

Question

Pulumi · Accepted Answer

To track the migration progress using AWS Migration Hub with Pulumi in TypeScript, you would typically use the `aws.migrationhub` module, which includes classes and methods to interact with AWS Migration Hub services. AWS Migration Hub provides a single location to track the progress of application migrations across multiple AWS and partner solutions.

Unfortunately, as of my knowledge cut-off, Pulumi does not have direct support for managing AWS Migration Hub resources such as `ProgressUpdateStream` or specific migration tasks.

However, you can perform operations against the AWS Migration Hub API using the AWS SDK in Node.js within a Pulumi program. This allows you to interact with Migration Hub and track the status of your migrations. Furthermore, you can create custom Pulumi resources that represent your migration tasks, and use dynamic providers to interface with the AWS SDK to check the status of these tasks.

Below is an example program that demonstrates how you might set up custom Pulumi resources to track migration progress using AWS Migration Hub and the AWS SDK for JavaScript in Node.js.

```typescript
import * as pulumi from '@pulumi/pulumi';
import * as aws from '@pulumi/aws';
import { SDK as AwsSDK } from 'aws-sdk';

// Initialize the AWS SDK for Node.js with credentials and region
const awsConfig = new pulumi.Config('aws');
const region = awsConfig.require('region');
const awsSDK = new AwsSDK({
    region: region
});

// Custom Resource type that interacts with AWS Migration Hub
class MigrationHubCustomResource extends pulumi.dynamic.Resource {
  constructor(name: string, args: MigrationHubResourceInputs, opts?: pulumi.CustomResourceOptions) {
    super(dynamicProvider, name, args, opts);
  }
}

// Define input properties for our custom resource
interface MigrationHubResourceInputs {
  progressUpdateStream: pulumi.Input<string>;
}

// Define the dynamic provider for AWS Migration Hub
const dynamicProvider: pulumi.dynamic.ResourceProvider = {
  async create(inputs: MigrationHubResourceInputs) {
    const migrationHub = new awsSDK.MigrationHub();

// Assume implementation details where you create a new progress update stream
    // or some other relevant action with AWS Migration Hub.

// Your AWS API interactions will happen here.

return {
      id: "migration-tracking-id",
      outs: {}, // Return your desired output fields here.
    };
  },

async read(id, props) {
    const migrationHub = new awsSDK.MigrationHub();

// Read the migration status from AWS Migration Hub.
    // Replace '...' with the actual API call and processing logic.

return {
      id: id,
      props: {}, // Populate with your actual read properties.
    };
  },

// Similarly, you will need to implement `update` and `delete` as needed.
};

// Use the custom resource to track a migration
const progressUpdateStreamName = 'my-progress-update-stream';
const migrationTracker = new MigrationHubCustomResource('myMigration', {
  progressUpdateStream: progressUpdateStreamName,
});

// Export data from your program here, if needed
export const migrationTrackerStreamName = migrationTracker.progressUpdateStream;
```

In this example, we define a custom Pulumi resource that uses the Node.js AWS SDK to potentially create and read migration tasks within AWS Migration Hub. The details of the interaction with Migration Hub's API (eg: creating progress update streams, submitting migration task statuses) would be implemented within the dynamic provider's `create`, `update`, `delete`, and `read` methods as per your specific requirements.

Tracking migration progress typically involves periodically polling the status of your migration tasks and handling any necessary updates or reporting within your application or infrastructure code. This example demonstrates the structure for setting up such interactions, but you would need to fill in the implementation details according to the specifics of the AWS Migration Hub API and your migration tracking needs.

Please note that using AWS services within Pulumi will require the proper setup of AWS credentials and configuration, which is assumed to be in place in this code. You should ensure that the Node.js environment where Pulumi runs has the necessary permissions to interact with AWS Migration Hub.
