AWS credits are a valuable resource for cloud computing beginners, obtained through various programs.
Steps to check and redeem AWS credits: Log in to the root account, access the Billing Dashboard, check credit balance, and redeem credits in the Credits section.
Best practices include using the root account for credit actions, monitoring expiration dates, and contacting AWS Support if credits are missing.
AWS credits can fund projects like hosting on S3, testing EC2 instances, using Lambda for serverless apps, but exclude support plans and some taxes.
