Description

WebSockets allow us to stream additional data from/to client/server beyond the limits of http request/response. This has opened a world of Real Time apps. Given that keeping Lambda functions running for long time will cost a lot (because we are billed per 100ms) we need to consider an alternative approach for sending data to the client after the initial page/data is rendered...

_Polling_?

Contributor guide

Research direction
Explore and compare polling, long polling, and Server Sent Events (SSE) as alternatives to WebSockets for real time interaction, considering AWS Lambda's cost model of per 100ms billing. Evaluate latency, resource usage, and implementation complexity.
