We suggest Paperspace now. Lesson 1 walks you through getting set up. It's very easy - there's a fast.ai template there ready to go. They have the best price/performance ratio of anyone at the moment for GPUs.
Can I still use AWS though? Does the setup scripts remain the same? I had already set up an AWS server (my company has provided us some cash for personal learning) from the old lessons, but haven't started the lessons yet.
It'd be great if I can switch to the new lessons but with AWS.
Yup AWS is fine too. We have a new AMI available if you want to use it, and also a predefined conda environment to add fastai/pytorch to an existing server. Lesson 2 covers AWS usage, and there's also step by step instructions linked from the forum.
How much should I budget for paperspace for completing the course?
If you remember to shut down your machine when you're done, and you do the suggested 10 hours per week, plus maybe an extra 5 hours of model training per week, at $0.45/hour for Paperspace's cheapest machine (still works great though): $47.25
