Some notes on the key features of AWS, used in Giraffael.

1. EC2 instance: Used to host remote server with assigned Elastic IP address.
   • An Elastic Block Storage was attached to the instance to provide extra storage space.
   • A Security Group was attached to the instance to specify Inbound and Outbound Rules
   • An Elastic Network Interface was attached to the instance, representing a virtual network card.
2. Secret in Secrets Manager: Used to store information of API keys.
   1. file structures that hold these info:
      1. cert.pem:
         1. -----BEGIN CERTIFICATE-----
         2. cert
         3. -----END CERTIFICATE-----
      2. key.pem:
         1. -----BEGIN PRIVATE KEY-----
         2. key
         3. -----END PRIVATE KEY-----
      3. .env: OPENAI_API_KEY=””
3. Roles in IAM:
   • EC2-SecretsManager-Access: Used to get EIP and secret values from Secrets Manager.
   • Giraffael2-get-server-elastic-ip-function-role-4t3uo992: Used to allow Read-Only-Access of EIP.
4. Policies in IAM:
   • AWSLambdaBasicExecutionRole: Attached to a Role to help accessing EIP of the instance.
5. Load Balancer in EC2: Not used, but might be needed in the future for auto-scaling of Client Authentication (Key exchanges, signature authentication, etc.).
