The web server you created in this workshops is in the free tier.
However you should take care to shutdown the instance and remove the storage volume so that you do not incur any costs.
On a related note, check out the pricing of EC2 instances and EBS volumes. You’ll see that
the pricing of instances varies widely. Our t2.micro instance in us-east-1 costs $0.0116/hr – that is, a little over a penny. Reading further,
you’ll notice that these so-called on-demand instances are actually charged per second.
Elastic Block Store (EBS) storage is charged a bit differently than EC2. Our EBS volume costs $0.08/GB-month. Notice that there are different choices for EBS volumes. These options will be discussed in an upcoming storage session.
