For example, if you're going to try Amazon EC2, it might help if you know what kind of operating system you need, what your memory requirements are, and how much I/O you need. You should also decide whether you need storage, if you're going to run a database, and how long you intend to use the servers. You don't need to make these decisions before generating an estimate; you can play around with the service configuration and parameters to see which options fit your use case and budget best. For more information about AWS service pricing, see [AWS Pricing](https://aws.amazon.com/pricing/services/). AWS offers free pricing and migration tools for you to use.
