I'm still new in the AWS Lambda & Api Gateway world, but it seems a good fit to my new project.
I still have some concerns, and I'll be very happy if you can assist.
In my new project (Financial data), I need to deliver different type of data :
- Historical data (I was thinking of HTTP Api in AWS API GATEWAY)
- Live streaming data (I was thinking of WEBSOCKET Api in AWS API GATEWAY)
- Market opportunity, based on websocket data I RECEIVE and analyse (WEBSOCKET Api in AWS API GATEWAY)
Here are my questions :
- In a serverless Lambda architecture, is it possible to LISTEN to websocket, then analyse the data, and send them back through the API Gateway websocket api ?
- Is DynamoDB a good Fit for large amount of historical data ? I know it's fast, but is'nt it a waste for data that will not be updated anymore ?
- Does it make more sense to use a "classic" nodejs framework, that manages REST and Websocket API, like SailsJs for example ?
Thanks a lot
