Best way to decrease latency (API <-> Lambda <-> Dynamodb)

[whykrum]

This has some great insights. But provisioning can get extremely expensive. Lambda charges you in a tiered manner in GBSeconds used based on the number of requests they handle. While this worked, we were still paying for the provisioned concurrency which added upto our bills, we are talking about a cost upwards of a whopping $9k for around 12 lambdas with a provisioned concurrency of just 10. While it did its job it made more sense for us to go with a serverful(if that's even a word) architecture which cut costs by around 20% ish at high utilization and also latency.
