Which factors affect costs in the AWS Cloud?

Explanations:

The number of unused AWS Lambda functions does not directly impact costs, as you are only billed for the compute time and resources consumed during function execution. If functions are not invoked, they do not incur charges.

While Amazon S3 charges for storage and requests, the number of configured S3 buckets itself does not affect costs. Charges are based on the amount of data stored and accessed, rather than the number of buckets.

Inbound data transfers into AWS services (like S3) are generally free of charge, so the number of inbound data transfers without acceleration does not affect costs. However, data transfer may incur costs when it exceeds certain limits or when using specific services.

Outbound data transfers without acceleration are charged based on the amount of data transferred out of AWS to the internet or other AWS regions. This can significantly impact costs, especially with high data transfer volumes.

Compute resources currently in use, such as EC2 instances or other services, directly impact costs. You are billed for the resources you provision and consume, making this a key factor in overall AWS expenses.
