SageMaker Studio & Notebook Instance Pricing Questions

Question

Hi Everyone,

I have some questions regarding the cost structure for different SageMaker components, specifically:

A) SageMaker Studio JupyterLab
B) SageMaker Notebook Instance

For **each**, I’d like clarification on the following:

1. How is usage billed—by second, minute, or hour? If it's by hour, does starting a Studio session or Notebook Instance for just one minute still incur a full hour's charge? If it's by second or minute, is there a minimum amount be charged?
2. If multiple data scientists share the same space (e.g., a shared Studio session or the same Notebook Instance), how is the cost calculated? For example, if two users collaborate using an ml.t3.16xlarge instance for one hour, and the cost for a single user is $1 per hour, would the total charge be $1 or $2?

These questions apply to both A and B. Thanks for your help!

I'll address your questions for both SageMaker Studio JupyterLab and SageMaker Notebook Instances:

A) SageMaker Studio JupyterLab:

1. SageMaker Studio is billed per second of usage, with a minimum of 1 minute. This means if you use Studio for just one minute, you'll be charged for that minute, not a full hour. The billing starts when you launch the SageMaker Studio application and ends when you log out or when an administrator ends your session.

2. In SageMaker Studio, each user gets their own dedicated workspace instance. If multiple data scientists are working in Studio, they would each have their own session and be billed separately. There isn't a concept of sharing the same Studio session among multiple users in the way you described.

B) SageMaker Notebook Instance:

1. SageMaker Notebook Instances are also billed per second of usage, with a minimum of 1 minute. Like Studio, if you use a Notebook Instance for just one minute, you'll be charged for that minute, not a full hour.

2. For Notebook Instances, multiple users can technically share the same instance, but it's not designed for simultaneous use by multiple users. If two users are using the same Notebook Instance, you would still be charged based on the instance type and the total time it's running, not per user. So in your example with an ml.t3.16xlarge instance used for one hour, the charge would be $1 (assuming that's the correct rate), regardless of whether one or two users were using it.

It's important to note that while sharing a Notebook Instance is possible, it's generally not recommended for collaborative work due to potential conflicts and security concerns. SageMaker Studio is better suited for multi-user environments, where each user gets their own workspace.

In both cases, you only pay for the compute resources you use, and there are no additional charges for using the SageMaker Studio or Notebook Instance interfaces themselves.
