Pricing of AWS
AWS offers a variety of pricing options, so you can choose the one that best fits your needs. Here are some of the factors that affect AWS pricing:
- The type of resources you use
- The amount of resources you use
- The region where you use your resources
- The duration of your usage
You can find more information about AWS pricing on the AWS pricing page.
Here is a simplified pricing example for an Amazon EC2 instance:
| Instance type | vCPUs | Memory (GiB) | Storage (GB) | Price per hour |
|---|---|---|---|---|
| t2.micro | 1 | 1 | 8 | $0.008 |
| m4.xlarge | 4 | 16 | 80 | $0.166 |
| c5.2xlarge | 8 | 32 | 160 | $0.333 |
This example shows that the price of an Amazon EC2 instance depends on the number of vCPUs, the amount of memory, the storage capacity, and the region where the instance is located.
AWS also offers a number of discounts, such as reserved instances and spot instances. Reserved instances are instances that you reserve for a certain period of time, and they can offer significant discounts on the hourly price. Spot instances are instances that are available at a lower price than on-demand instances, but they can be terminated at any time.
You can learn more about AWS pricing and discounts on the AWS pricing page.
