AWS Free Models

 

On deep insight, AWS free tier has three distinct models.  Let us review them

Free Tier 1 - Always Free

This section is a baseline level, which is always free for the underlying services. As an example, it is possible to invoke 1 million Lambda invocations for free, also get “up to 3.2 million seconds of compute time” per month. Also, one million free requests per month and 400,000 GB-seconds of compute time per month.

Free Tier 2 - One Year Limit

This free tier is a 12-month period starting the day you first create your account. During this period, roughly 36 services offer you free usage up to certain limits. Few snapshots are:

  • 30GB a month of free EBS (disk volume) storage
  • 750 hours a month of t2 or t3 micro instance usage
  • 1GB of data transfer out to the internet for free each month in perpetuity
  • free t2.micro in regions where they’re available
  • free 1 Oracle RDS instance but only if you bring your own license
  • one free load balancer but it’s only an ELB-classic or an Application Load Balancer

Free Tier 3 - Trials

It is a service specific limited-time trial period that begins from your first use of a service. This applies to any use of the service, by any user in the account.

As an example, on enabling Amazon Detective, it’ll be free for 30 days; then it will be charged.
