AWS Bedrock + xLink in 5 Minutes

Install xLink Cloud Integration

xLink includes a cloud integration layer that handles AWS Bedrock authentication without IAM roles or access keys.

# Install xLink with cloud integration support
npm install @private.me/xlink @private.me/cloud-integrations

# Or using yarn
yarn add @private.me/xlink @private.me/cloud-integrations

Configure AWS Bedrock Access

xLink uses cryptographic identity to authenticate with AWS Bedrock. No IAM roles, no access keys, no credential rotation.

import { configureCloudIntegration } from '@private.me/cloud-integrations';

// One-time setup: register your xLink identity with AWS Bedrock
await configureCloudIntegration({
  provider: 'aws-bedrock',
  region: 'us-east-1',
  identity: await connect('bedrock-access') // xLink identity
});

What Happens Under the Hood

• Identity Generation: xLink creates a cryptographic identity (DID) for your application
• Cloud Registration: The integration layer registers your DID with AWS Bedrock
• Zero Credentials: No access keys, secret keys, or session tokens are generated
• Cross-Account: Works across AWS accounts without VPC peering or transit gateways

Invoke Bedrock Models with xLink

Replace AWS SDK authentication with xLink identity. Same API, zero IAM complexity.

import { connect } from '@private.me/xlink';

// Connect to Bedrock via xLink identity
const bedrock = await connect('bedrock-access');

// Invoke Claude 3.5 Sonnet on AWS Bedrock
const response = await bedrock.value.agent.send({
  to: 'anthropic.claude-3-5-sonnet-20241022-v2:0',
  payload: {
    messages: [
      { role: 'user', content: 'Explain quantum computing in simple terms' }
    ],
    max_tokens: 1024,
    temperature: 0.7
  }
});

console.log(response.value.content);

// Invoke Meta Llama 3.3 70B Instruct
const llamaResponse = await bedrock.value.agent.send({
  to: 'meta.llama3-3-70b-instruct-v1:0',
  payload: {
    prompt: 'Write a haiku about machine learning',
    max_gen_len: 512
  }
});

console.log(llamaResponse.value.generation);

Traditional AWS SDK Approach (What You Replace)

// OLD: IAM roles, credentials, session tokens
import { BedrockRuntimeClient, InvokeModelCommand } from '@aws-sdk/client-bedrock-runtime';

const client = new BedrockRuntimeClient({
  region: 'us-east-1',
  credentials: {
    accessKeyId: process.env.AWS_ACCESS_KEY_ID,     // Leaked = breach
    secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY, // Rotated = cascade
    sessionToken: process.env.AWS_SESSION_TOKEN     // Expired = outage
  }
});

const command = new InvokeModelCommand({
  modelId: 'anthropic.claude-3-5-sonnet-20241022-v2:0',
  body: JSON.stringify({ /* ... */ })
});

const response = await client.send(command);
// ^ IAM policies, VPC endpoints, KMS keys, CloudTrail logs...

xLink Approach (Zero IAM)

// NEW: Cryptographic identity, zero credentials
const bedrock = await connect('bedrock-access');
const response = await bedrock.value.agent.send({ to, payload });
// ^ No IAM, no credentials, no cascade failures

Zero IAM Complexity

xLink eliminates the most complex parts of AWS Bedrock deployment.
