11. Using Cloud Services We will heavily use Amazon AWS services
You are expected to launch instances on AWS to deploy some of your projects you are developing.
AWS provides free-tier 64-bit Ubuntu instances!
Welcome to participate in the ​AWS Educate program ( which can provide $100 AWS credits per student.

Working together the projects (only) is strongly encouraged. (The problem sets should be done individually). You can form groups of no more than 2 students.
Students may leave their existing group in the quarter. BUT they cannot join any new group after the end of the second week.
In addition, for each group splitting, the group members should tell the reader at least two weeks before the corresponding project/homework deadline.
