Google Cloud Platform (GCP) is a suite of cloud computing services offered by Google. As part of those services, we can run a Jupyter Notebook.
GCP is offered as a subscription and time-usage billing. That means you pay a certain amount per month and you pay for how much you use per month. I think their fees are at par with other hosting arrangements. They have a free trial period that you can try out. Remember to shut down/off any services you start; otherwise the clock will keep ticking and you will get billed.
There are several steps to getting Jupyter installed and running on GCP. Many of these steps are performed using a Linux shell window.
