+# Lambda Managed Instances with Amazon Bedrock
+
+This pattern deploys a Lambda function on [Managed Instances](https://docs.aws.amazon.com/lambda/latest/dg/lambda-managed-instances.html) (EC2-backed compute) that invokes Amazon Bedrock (Claude) for text generation.
+
+Learn more about this pattern at Serverless Land Patterns: https://serverlessland.com/patterns/lambda-managed-instances-bedrock-cdk
+
+Important: this application uses various AWS services and there are costs associated with these services after the Free Tier usage - please see the [AWS Pricing page](https://aws.amazon.com/pricing/) for details. You are responsible for any AWS costs incurred. No warranty is implied in this example.
+
+## Requirements
+
+* [Create an AWS account](https://portal.aws.amazon.com/gp/aws/developer/registration/index.html) if you do not already have one and log in. The IAM user that you use must have sufficient permissions to make necessary AWS service calls and manage AWS resources.
+* [AWS CLI](https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2.html) installed and configured
+* [Git Installed](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
+* [Node and NPM](https://nodejs.org/en/download/) installed
+* [AWS CDK](https://docs.aws.amazon.com/cdk/latest/guide/cli.html) installed
+
+## How it works
+
+Lambda Managed Instances combine EC2 flexibility with serverless simplicity:
+
+- **EC2-backed compute**: Your function runs on dedicated EC2 instances in your VPC
+- **Serverless management**: AWS handles provisioning, scaling, OS patching, and load balancing
+- **Cost optimization**: Use Compute Savings Plans and Reserved Instances for Lambda workloads
+- **Specialized hardware**: Access Graviton, GPU, and network-optimized instance types
+
+This pattern adds Bedrock integration to demonstrate a real-world use case beyond hello-world.
+
+## Architecture
+
+```
+User → Lambda Function (on Managed Instances / EC2)
+         ├── VPC with private subnets
+         ├── CapacityProvider (ARM64)
+         └── Bedrock InvokeModel → Claude response
+```
+
+## Deployment Instructions
+
+1. Clone the repository and navigate to the pattern directory:
+    ```bash
+    git clone https://github.com/aws-samples/serverless-patterns
+    cd serverless-patterns/lambda-managed-instances-bedrock-cdk
+    ```
+
+2. Install dependencies:
+    ```bash
+    npm install
+    ```
+
+3. Deploy the stack:
+    ```bash
+    cdk deploy
+    ```
+
+## Testing
+
+Invoke the function:
+
+```bash
+aws lambda invoke \
+  --function-name managed-instances-bedrock-cdk \
+  --payload '{"prompt":"Explain Lambda Managed Instances in 3 sentences"}' \
+  --cli-binary-format raw-in-base64-out \
+  output.json && cat output.json | python3 -m json.tool
+```
+
+## Cleanup
+
+```bash
+cdk destroy
+```
