Question
Bandwidth of various node types on Kubernetes?

Asked by apmed
I am trying to find out what the bandwidth is for a given node type, when Digital ocean kubernetes is used. Here is a page I came across.
https://docs.digitalocean.com/products/kubernetes/concepts/choosing-a-plan/#network
Basic (regular and premium) (shared) - “low traffic servers” General Purpose (dedicated) “medium to high traffic servers”
What is ‘low traffic’ and what is ‘high traffic’? Can you provide some minimum bandwidth we could get for Internet access? In other words, what is the minimum bandwidth from Internet to Kubernetes pods, and from the Internet pods to Kubernetes?
What is the minimum expected bandwidth between the pods, and between the nodes? (east-west traffic)?

Hi there,
The Managed DigitalOcean Kubernetes clusters will accrue free bandwidth based on the worker pool’s largest sizes within 28 days of usage. For example, if your worker pool has Droplets with a monthly bandwidth quota of 5TB, then you will accrue free bandwidth at the rate of
5TiB/(24*28) * worker_pool_size = 7.44 GiB/hr * worker_pool_size.Note that, for autoscaling clusters, the size of the worker pools vary.
Regarding the different Droplet types, I could suggest using the following bandwidth calculator tool which will give you a good overview of the differences and you can play around with the various values and Droplet types:

Hope that this helps!

I understand the application-level or the effective bandwidth will depend on a lot of factors such as the kind of applications running on the pods, the databases in use etc. etc. This question is only about the link-layer bandwidth in the kubernetes infrastructure.
