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:)
