If they're evenly distributed, 100K requests per day are barely 1/sec. It's peak throughput for which you should be planning. At 1/sec you can use just about anything.

That aside, if you're not sure if you should be using it I'm going to guess the answer is, "No you shouldn't". It's very cool tech but most likely overkill for whatever you're doing. Also, until recently securing it was a particular pain due to lack of TLS and authentication (I think this may have been resolved now).
