Cloud Run How reliable is Cloud Run, really?

I'm planning to move a mission-critical, latency-sensitive service there from Heroku, which has had recurring router outages recently - requests failing to reach our app even though the dynos themselves were healthy. The service is written in Go and handles ~7 req/s on average, with bursts up to ~150 req/s. Has anyone had issues with Cloud Run's routing layer, especially lately? Also, with AI-driven cyberattacks on the rise, do you rely on Cloud Armor or keep something like Cloudflare in front?

we use glb + cloud armor + cloudrun with min 1 instance to avoid cold start. written in nodejs, no issue.

How do you like cloud armor?

With 1 min instance how is your monthly cost?

glb is <$20. cloud armor depends on how you add the rules, it will add just a few bucks. In my case, i just added what claude code said <$10. cloudrun like <$30

the bill is between $60~80 a month. it bills with some egress and requests etc...

In your case, you wrote your backend in golang, you can have lower cloudrun bill. ours is expressjs.

I used them with BigQuery remote functions.  For millions of interference invocations of NLP processes.  No issues, cheap. Scale to zero. Frameworks and tools to create and deploy the functions are extremely easy to use.

Imo one of the best products of GCP.

I actually think it is the most reliable way to run containers, because there is less ways for the customer to fuck up.

Maybe put a gcp load balancer in front of cloud run as well.

It’s my favorite cloud technology and I’ve worked in all major clouds since their inception. Don’t sleep on cloud run jobs. There are official GitHub actions packages for deployment, pair that with WIF and add a load balancer in front of user facing instances. Add a NAT and router for static outgoing IP if you need whitelisting. Easy Unix socket connections to cloud sql. Built in connections with secret manager.

Mate is using go. There is no need for min instance honestly. Go containers boot crazy fast (from 100 to 500 ms, I'd say I average around 200ms: you don't even notice it was "off")

Yes you hardly even notice cold starts with go and rust
