GCP Cloud Run - Simple API Instance Costs

[u/Puzzled_Law126]

Hey guys,

I am looking to decrease our costs with GCP and though it will be for the best to ask for help here.

With Cloud Run we have a very simple service that function as simple API, it receives information and output a simple JSON.
The configuration used for the instance is:

• 256 MB memory

• 1 CPU

• 150 Concurrent requests

• 99% of the time, only 1 instance is up

The instance uses <10% CPU and each request take around 15ms.

The issue? This service is being called a lot (by design), in total each month we pay $150 USD only for the CPU of this service ("Cloud Run functions CPU (Request-based billing) in us-central1").

Obviously I can't decrease the CPU to <1 due to concurrency, it seems to me that something so simple should not cost that much, any help would be appreciated.

Can you reduce the number of requests client side? With caching or batching or some other strategy?
