Cost was incurred in glue and vpc. I want to know the cause and how to solve it.

Hello.

As you know, Glue fees are the fees for running Glue Jobs and crawlers.
For VPC, charges for public IPv4 addresses are recorded.
AWS started charging for public IPv4 addresses starting in February 2024.

You can use a public IPv4 address attached to EC2 for 750 hours per month for free for 12 months after creating an AWS account.
However, public IPv4 addresses attached to other than EC2 are charged.
If the free tier of your AWS account has already expired, public IPv4 addresses will be charged.

I recommend that you use IPAM to check if there are any public IPv4 addresses attached to anything other than EC2.

If you have questions about billing for your AWS account, you may be able to find more detailed information by opening a case with AWS Support under "Account and billing."
Inquiries under "Account and billing" can be made free of charge.
