I am trying to launch a kubernetes cluster over EKS which would have multiple pods in it . Once the worker node has maximum pods on it running then a new node launches and the extra pod launches over the new node. Launching of a new node takes time and creates a downtime which I want to reduce. Pod disruption budget is one option but I am not sure how to use it with scaling up of nodes.

A simpler way to approach this would be to have your scaling policies pre-defined to scale up at reasonably lower limits. This way, let's say if your server reaches 60% of the capacity and triggers a scale up - you would have enough grace time to not face a downtime (since the first one can handle requests while the second one bootstraps) and allow the the new server to come up.
