Want to confirm if AWS charges are hourly? Also need clarity on Windows instance pricing

Hello.

EBS pricing is described in the following documentation:
Please note that even if you stop EC2, you will still be charged for EBS unless you delete it.
https://aws.amazon.com/ebs/pricing/?nc1=h_ls

$0.10 per GB-month of provisioned storage

Data transfer charges are listed in the following documents:
Charges will be incurred when data is transferred from EC2 to the Internet or when communicating with EC2 in another Availability Zone.
https://aws.amazon.com/ec2/pricing/on-demand/?nc1=h_ls#Data_Transfer

Let me clarify the pricing details for your AWS Windows instance:

1. Hourly charging: For Windows On-Demand instances, you are charged by the second, with a minimum of 60 seconds. So while the price is listed per hour, you're actually billed for the exact usage time in seconds (after the first minute).

2. Stopping the instance: When you stop your EC2 instance, you will no longer be charged for compute resources. However, it's important to note that you will still be charged for any attached EBS volumes, as these continue to persist even when the instance is stopped.

3. EBS gp2 pricing: The cost for gp2 (General Purpose SSD) EBS volumes varies by region. As you haven't specified your region, I can't provide an exact price. However, gp2 volumes are typically priced per GB-month of provisioned storage. You'll need to check the specific pricing for your region on the AWS pricing page.

Remember that while stopping the instance halts compute charges, you'll still incur costs for the EBS storage. If you want to completely avoid charges, you would need to terminate the instance and delete any associated EBS volumes.

Also, keep in mind that there may be additional costs beyond just the instance and storage, such as data transfer or other associated services you might be using.
