Free AWS Services
In looking at the AWS (Amazon Web Services) pages, you may have noticed that they don’t supply a single list of all the free services. What you get instead are various mixes of services that tell you something about the services but don’t really help you understand what services are actually available.
This table lists the various free services and tells you the vital statistics about each one so that you now have a single list of what you can get free.
|Service Name||Description||Non-expiring||Limitations||In Beta|
|Amazon API Gateway||Allows you to roll your own API for use in applications generated by your own organization or any third party to whom you give access.

|Amazon Simple Queue Service (SQS)||Provides a fully managed queuing service. Queuing lets you decouple cloud application components so that components need not run at the same time. This service is often used with Amazon Simple Notification Service (SNS).||Yes||1,000,000 Requests||No|
|Amazon Simple Storage Service (S3)||Allows storage of data objects of any sort in the cloud. The three levels of storage enable you to perform short-term (Standard service), middle tier (Infrequent Access, IA), and long-term storage (Glacier).

Consider some of the limitations. For example, the AWS Device Farm service access doesn’t expire. However, you get only a one-time free trial of 250 device minutes. This means that if you use five devices, you can test each of the devices for only 50 minutes before the free offer expires. You don’t get a monthly allotment with this particular service, so carefully using the time you get is important.
When reviewing the terms of usage for various services, you need to read carefully and ask lots of questions. For example, the overview of Amazon AppStream tells you that you get 20 free hours per month, but that’s where the description of what free means ends. The 20 free hours apply to the total of applications and devices you’re using. For example, if you have four applications to run on five devices, you have only an hour of free usage per month, not 20 free hours as you might initially think.
Some of the services will also seemingly appear out of the nowhere when you get an invoice for the services you used. For example, AWS Data Transfer entries will appear anytime you need to transfer data from one service to another. These transfers occur in the background, so you may not even realize that they’re happening. This blog post tells you how you can minimize these costs. In addition, the blog post helps you understand how the costs are tiered based on where the move takes place, such as between regions.
