+# 🚀 DynamoDB Modernization Infrastructure
+
+> **CloudFormation Template for MySQL to DynamoDB Migration Workshop**
+
+A comprehensive CloudFormation template that sets up all required infrastructure components for the database modernization workshop, simulating an on-premises environment with MySQL database and providing the complete toolkit for migration to Amazon DynamoDB.
+
+## 🔧 Infrastructure Components
+
+This (`modernizer-db.yaml`) template creates a secure development environment based on VS Code Server, accessible through a browser and protected by user authentication. Workshop materials and utilities come pre-loaded in the environment. The database layer consists of a fully configured MySQL instance populated with sample e-commerce data, along with monitoring capabilities and secure credential management.
+
+Network infrastructure is configured with appropriate security groups and VPC endpoints to ensure secure communication between services. A CloudFront distribution provides fast, secure access to the development interface.
+
+The migration components include necessary IAM roles for DynamoDB, Glue ETL processes, and Lambda functions. An S3 bucket serves as the staging area, while pre-configured Glue connections streamline the database migration process. Docker support is included for compatibility testing across environments.
+
+## 📋 Prerequisites
+
+Before deploying this CloudFormation template, ensure you have:
+
+1. **AWS Account Access**: Administrative permissions in your AWS account
+2. **Public IP Address**: Your current public IP address for security group configuration
+3. **Region Selection**: Choose a region with support for all required services
+4. **CloudFormation Knowledge**: Basic understanding of AWS CloudFormation
+
+## 🚀 Deployment Instructions
+
+### Step 1: Deploy CloudFormation Template
+
+1. Navigate to the AWS CloudFormation console
+2. Click "Create stack" > "With new resources"
+3. Upload the `modernizer-db.yaml` file
+4. Complete the parameters form with required information:
+   - Environment name
+   - Your public IP address for access control
+
+### Step 2: Accessing Your Development Environment.
+Once your CloudFormation template is CREATE_COMPLETE, access the "Outputs" tab to retrieve your environment credentials.

+
+Locate these two important values:
+   - VSCodeServerPassword - Authentication credential for your VS Code instance
+   - VSCodeServerURLModernizer - Direct endpoint to your cloud-based IDE
+
+Your values are unique to you and will differ from the above example.
+
+Click the VSCodeServerURLModernizer to launch your development environment. Enter the password when prompted and allow approximately 60 seconds for the environment to initialize. Any startup notifications can be safely dismissed.

+## 🔍 Infrastructure Details
+
+### 📊 Resource Specifications
+
+| Component | Specification | Notes |
+|-----------|---------------|-------|
+| EC2 Instance | t4g.large | ARM-based for cost optimization |
+| Storage | 40 GB gp3 | Encrypted EBS volume |
+| MySQL | 8.0+ | Community edition |
+| Network | Default VPC | VPC endpoints for optimization |
+| Python | 3.13 | Latest version for compatibility |
+| Node.js | v18 | LTS version for stability |
+
+## 🚮 Cleanup Instructions
+
+1. After executing the workshop, you would have created three DynamoDB tables: Users, Products, Categories. Please delete them using the DynamoDB AWS console as indicated in the below picture:
+       <img width="800" height="300" alt="image" src="https://github.com/user-attachments/assets/0c0fe99c-fb71-48d8-9d4f-4863b6ee1b99" />
+
+   If you prefer you can use below AWS CLI commands to delete the DynamoDB tables:
+
+               $ aws dynamodb delete-table --table-name Categories --region us-west-2
+               $ aws dynamodb delete-table --table-name Products --region us-west-2
+               $ aws dynamodb delete-table --table-name Users --region us-west-2
+
+3. After executing the workshop, you would have also created three Glue jobs: users_migration_job, product_migration_job, categories_migration_job. Please delete them using the Glue AWS console as indicated in the below picture:
+        <img width="800" height="300" alt="image" src="https://github.com/user-attachments/assets/7f77fb58-c7fb-4b3a-8da6-2b0e382b70bc" />
+
+   If you prefer you can use below AWS CLI commands to delete the Glue jobs:
+
+               $ aws glue delete-job --job-name categories_migration_job
+               $ aws glue delete-job --job-name products_migration_job
+               $ aws glue delete-job --job-name users_migration_job
+
+4. Finally, delete the CloudFormation stack you deployed as part of this workshop. You can delete the CloudFormation stack as shown in the below picture:

+
+   If you prefer you can use below AWS CLI commands to delete the CloudFormation stack:
+
+               $ aws cloudformation delete-stack --stack-name <StackName>
