Hello, I am using the free account for testing and in the future to implement and continue using your GCP services.
I have two applications on App Engine that probably won’t even pass the free quota, if it does, it won’t be much, however, I’m analyzing the revenue generated and I saw that it is generating a relatively high amount of value daily for a small application like mine, which could become impracticable.
I analyzed and saw that the cost probably refers to the configuration made using VPC serveless and Cloud NAT to use a static outgoing IP address for App Engine, as I need to connect to my MongoDB database on Altas in a secure way .
I followed the following tutorial for the same: https://cloud.google.com/appengine/docs/standard/nodejs/outbound-ip-addresses?hl=pt-br .
Is this really the only viable solution for my case? I wouldn’t like to open access for all in MongoDB and it doesn’t seems a good idea using the range of IPs that google uses because it can changes. It seems to me that this way of having a static IP for App Engine will cost a lot for a small application since the VPC network needs at least 2 instances of an f1-micro VM. If this is the case, I may have to consider moving my platform to another cloud.
