KIddo Project specifications

1. User Authentication - Cognito user pool
2. Front end - Javascript SDK and aws-amplify SDKs with few cognito SDKs for development.
3. Federated Identities - Facebook POC
4. Lambda function
5. API gateway 5)DynamoDB 6)IAM policies - Roles for users and AWS services
6. VPC set up
7. S3 for logging and backup

Database design :

Kiddo Main table

1. Leading Keys : cognito-identity-Id - partition key
2. Sort Key : Kidd0-watch-ID
3. Heart rate - (Combination of number and time stamp).
4. Skin Temp - (Combination of number and time stamp)
5. steps - (Combination of number and time stamp). 6)Activity - (Combination of number and time stamp).
6. GST - Galvinic skin response (Combination of number and time stamp).

--> Scheduled tasks to trigger the batches from devices to update the data periodically --> Other Jobs to run Asynchronousouly to update health data derived from activity data.

Current Challenges in AWS services :

--> Cannot implement row level DynamoDB access control through IAM policies when there is an API gatway and Lambda in middle of connection to DynamoDB. --> facebook user cannot be synced with the cognito user automatically even if both are registered with same email ID

Create VPC

--> Create a VPC with 10.0.0.0/26 IP address --> Edit DNS host names and Enable it. --> Create Subnets with Private configurations. --> Create a route table for Private. --> If you want the internet access you will need Internet gateway and NAT Gateway incase of private routes. --> Assign the Lambda function to VPC , Subnet ,Route table and security group --> Create a VPC end point and assign that endpoint to the dynampDB. --> API Gateway will be public to provide the access to end points.
