I use AWS EC2 free tiers and Elastic Beanstalk. I didn't buy any services from AWS yet.
When I login as a root, AWS informs me that I'm going to exceed the Free Tier usage limit:
I want to see the report. I do all that this docs says https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/usage-reports-instance.html#viewing-instance-usage But AWS doesn't show me reports. I set all the necessary filters correctly:
Why? How to make AWS to show report?
回答1:
I figured that out.
I have never used any AWS storage services explicitly yet. I only test Elastic Beanstalk now to have my hands on AWS. Docs says Beanstalk in free, you only pay for AWS resources that Beanstalk uses. And Beanstalk always created free t2.micro instance for my Node.js web server and I never had over-limit requests to my sample test apps. However I often uploaded new versions of my apps as .zip bundles. And that Elastic Beanstalk charged me for that! In November it suddenly charged me $2 for S3 usage. I never used S3, but Beanstalk did it. Silently.
Be careful playing with Beanstalk. Beanstalk makes all those PUT requests to S3 behind the scenes.
It it better to use EC2 instance with EBS storage. EBS offers for free:
2 000 000 I/O operation (S3 only 20 000 GET, 2000 PUT)
30 Gb storage (S3 only 5Gb)
1 Gb for snapshots (S3 doesn't)
For development and test environments free EBS General Purpose (SSD) is good enough. But Beanstalk doesn't use it. It uses expensive S3.
