Google Cloud Run

I would like to build a mobile app that can scale to around 1M users over 1 year. We are currently testing with 100 users without any real load issues. We use the MERN stack with React Native Expo, and Google Cloud Services for GCB. We also use Google Cloud Run. We use a microservices architecture that we manage ourselves but thought of using Kafka. However, I need advice on optimising the app in terms of:

1. load balancing,
2. caching,
3. database optimisation,
4. autoscaling,
5. load testing, and
6. continuous optimisation frameworks

Any help would be appreciated! Thanks:)

What are the best options to host a Spring Boot application that acts as a receiver and publisher from Google Cloud Pub/Sub. I am using Google App Engine to do that, but there is Google Cloud Dataflow and Google Cloud Run that can be used. Which is the best option that can be used for this purpose and also that can handle the failover scenarios as well. Thanks!

Context: I wanted to create an end to end IoT data pipeline simulation in Google Cloud IoT Core and other GCP services. I never touched Terraform meaningfully until working on this project, and it's one of the best explorations in my development career. The documentation and syntax is incredibly human-readable and friendly. I'm used to building infrastructure through the google apis via Python , but I'm so glad past Sung did not make that decision. I was tempted to use Google Cloud Deployment Manager, but the templates were a bit convoluted by first impression. I'm glad past Sung did not make this decision either.

Solution: Leveraging Google Cloud Build Google Cloud Run Google Cloud Bigtable Google BigQuery Google Cloud Storage Google Compute Engine along with some other fun tools, I can deploy over 40 GCP resources using Terraform!

I use Google Cloud Run because it's like bring your own docker image to Google Cloud Functions.

I use it for building Dash Apps

It creates a nice url for web apps, and I see it being the evolution of serverless if GCP can scale this up.
