I have received cloud resources vouchers for ECS, RDS, and MongoDB along with 5 certification courses.
Seems like 0-5gb is free for OSS, i’ll use that
OSS & Function Compute are chargeable, you can also read about this on contest page.
“Alibaba Cloud resources include: ECS (Elastic Compute Service), RDS (Relational Database Service), OSS (Object Storage Service), Function Compute, MongoDB, 5 Clouder Courses and Exams. Note: If you want to use OSS or Function Compute, you will have to enter your payment details, even though actual payment is not needed.”
Yes, that’s the free usage limit.
