AWS, also known as Amazon Web Services, is a cloud computing IaaS and PaaS platform service provided by Amazon. Amazon AWS has long supported free trial services, but requires credit card activation for verification. Once verified, you can use the service for free for one year.

However, there are requirements for the free package. For example, EC2 virtual machines have a monthly limit of 750 hours for Linux and Windows micro instances. According to users, the monthly data transfer limit is only 30GB, so it is only suitable for testing and should not be used for high-traffic applications.

领取流程：

• Register for an AWS account
• Activate credit card verification
• Choose the free package

注意事项：

• The free EC2 package has a monthly limit of 750 hours, so it's best not to run two instances at the same time.
• The data transfer is said to be limited to 30GB, but I couldn't find this information on the official website.
• Snapshots are charged separately.
• Regularly check your bill.
• During the verification process, a few dollars will be charged from your bank account, but will be refunded after a period of time.
