🚀 AWS Cloud-Integrated Flask Project (End-to-End)

This project is designed to help you complete your AWS Week 30 & 31 modules. It integrates several core AWS services into a single, functional application.

🛠️ Integrated Services

• DynamoDB: Real-time visitor counter.
• SQS: Task queuing for background processing.
• SNS: Critical security alert notifications.
• Secrets Manager: Securely fetching API keys/config.
• AppConfig: Dynamic "Maintenance Mode" toggles.
• CodeBuild: Automatic Docker image builds via buildspec.yml.
• ECR/ECS: Containerization and orchestration.

📋 Step-by-Step AWS Setup Guide

Follow these steps in your AWS Console to make the application fully functional:

1. DynamoDB (Week 31)

• Create a table named VisitorCount.
• Partition Key: id (String).
• Once created, add an item: { "id": "global_stats", "visitor_count": 0 }.

2. SQS (Week 30)

• Create a Standard Queue named MyOrderQueue.
• Copy its URL and add it to your environment variables.

3. SNS (Week 30)

• Create a Standard Topic named MyAlerts.
• Create a Subscription (Protocol: Email) and confirm the link in your inbox.
• Copy the Topic ARN for your configuration.

4. Secrets Manager (Week 30)

• Create a secret named AppSecretKeys.
• Select "Other type of secret" and add key-value pairs (e.g., api_key: sample_key).

5. AppConfig (Week 30)

• Application: MyFlaskConfig
• Environment: Production
• Configuration Profile: MaintenanceMode
• Add a JSON configuration: { "maintenance_mode": false }.
