To Scale or Not To Scale?

Architecture Diagram
  1. Store API tokens from Interactive Brokers, IEXCloud, and other financial data platforms securely using AWS Secrets Manager.
  2. Use Amazon API Gateway to create an endpoint for our AWS Lambda functions and connect to these APIs securely using the API tokens.
  3. Use Lambda functions to access database credentials from Secrets Manager to connect
  4. Automatically rotate API keys and credentials every 30 days for best practice.
  5. Post real-time pricing and ticker data, using Lambda, to our internal PostgreSQL database from the endpoint, created using Amazon RDS.
  6. Execute trade orders against the database and query results using Lambda functions and store transaction data in real-time into a data lake, using Amazon Simple Storage Service (S3).
  7. Query data from the database using Lambda functions and then use AWS SageMaker to build, train, and deploy data science models based on findings.
  8. Query data from logs stored in S3 to feed data models in SageMaker.
  9. Send portfolio status reports to end users using Amazon Simple Notification Service (SNS) as the primary messaging service. (Add SNS to diagram and renumber steps)
