  1. This is a really good article. I didn’t know that pm2 had cluster mode and it actually means LBing. Thank you very much.

  2. How do you create clustering to multiple EC2 instances?
    I’m looking on to run a cluster of EC2 instance with NodeJS clustering talking to a MySQL database in Master + RR

    Thanks for your thoughts in advance!

    1. Hey Ashley,

      Clustering EC2 instances will be more like load balancing and that would need the application to be stateless.

      Rather than that possibly look at AWS Fargate (or Google cloud run). Another way of doing it might be a full on Kubernetes (EKS) but that might be too much depending on the use-case. It might be easier to try out AWS Lambda and scale up to Fargate/ECS than dabble with EC2 VMs.
