Scaling Web-service

We need to scale our web-service on with a Node (Next.js) app deployed.If we want to scale the service and upgrade to 2 CPUs, what does that actually mean?
Will the environment become load-balanced?
I cannot find more information on the website on this.

Hi Richard, I think you might be mixing up the horizontal and vertical scaling concepts here. What is the reason you are scaling up? Do you need more compute power or do you need to handle more user load? If you need to increase your CPU / memory limits, you can upgrade to a higher plan. Read more about our plan pricing here. If you are looking to increase your application replicas for handling more load, you can change the number of instances in your service settings. We are also rolling out our horizontal autoscaling feature soon, so keep an eye out for that as well.
