You should be able to log into your AWS accounts. You have permissions to use the following services:
launch EC2 instances,
create S3 buckets to store objects,
create a Database,
view metrics related to resources you are using on cloudwatch,
simple email service
So, this should be sufficient for your project. If you want to be able to launch new AWS services as part of your project, please let me know with details on your use case and I am happy to enable the service.
You will not need to pay for the resources you consume on AWS. However, please ensure that you use only the resources you need for your project (this allows support more students and give everyone a chance to use the AWS resources). Since you will not be running large workloads, you can use the T2.micro or T2.small instances (or T3 instances of the same size) for your projects. Please feel free to play with these resources.
You can also use your Amazon.com account (if you have one) to register for AWS training videos that teach you introductory material on different AWS services. Some helpful ones are:
Introduction to Amazon Elastic Compute Cloud (EC2). https://www.aws.training/Details/Video?id=16382
PostgreSQL Fundamentals: Explain. https://www.aws.training/Details/eLearning?id=43291
Introduction to Amazon Virtual Private Cloud (VPC). https://www.aws.training/Details/Video?id=15884
Look forward to speaking with you tomorrow.
