Status:

• A. Develop a Service

• B. Create CloudFormation template

• 1) The data at rest in DynamoDB is encrypted using AWS KMS service.

• 2) Data bigger than 4K can be stored.

• 3) Service exposes an API over TCP using serialized Google protocolbuffer messages as payload.

• 4) Rebar (https://github.com/rebar/rebar) is used for building and creating deployments.

• 5) Erlcloud (https://github.com/erlcloud/erlcloud.git) is used to access AWS services.

• 6) A simple test-client is included with server which invokes requests over GPB / TCP interface to verify the Service functionality.

• 7) Service is deployed using CloudFormation template into existing VPC network.
