Amazon Kinesis Data Streams Alternative

[outplex]

Hi team,

I'm currently developing an IVR system for a nonprofit organization with a limited budget. This solution utilizes Amazon Kinesis Data Streams, which incurs hourly charges, regardless of usage, and is not covered under the AWS Free Tier. Given the low call volume (approximately 7 calls per week), we are looking for alternatives or a workaround to minimize costs, as Kinesis continues to accrue charges even when the system is idle.

Is there an alternative service we could use to replace Kinesis Data Streams, or a way to disable it when not in use and programmalically recreate it on demand?

I would greatly appreciate any suggestions or guidance on reducing these costs.
