Thinking about Cloud adoption, but confused over pricing

Cloud service providers’ customer list spans from individual developers to large enterprises. The top three cloud providers — Amazon Web Services, Google Cloud Platform, and Microsoft Azure — offer free trial versions of various services. These free offers come with limited resources and can’t fulfill the full production needs. However, the free trial gives you an idea of how services will work without even paying anything for it.

There are basically two types of offerings under Free Tier, i.e., “free for a limited time” and “always free.” The services under each type of Free Tier can vary as per the cloud provider. There may be instances where a cloud provider offers one service free for a limited time and the other cloud provider offers similar service free for lifetime with certain limitations.

Here, we will explore the key aspects of Free Tier offerings by top cloud providers — AWSMicrosoft Azure, and Google Cloud. Read to understand the similarities, differences, and limitations of each offering.  

AWS vs Microsoft Azure vs Google Cloud Platform (GCP) Free Tier Types

As already mentioned, there are only two types of free tiers, namely:

1. Free for Limited-time:

Cloud providers offer you certain services free for 12 months. This free tier is offered only to the first sign-up or registrations with the services and that too with certain limitations. You will be charged for services as per the usual rate 12 months after you first signed up.

2. Always Free:

There are a few services that cloud providers offer that are free for lifetime, but this comes with a monthly limited usage of those services. You can manage the monthly usage of services via consoles offered by the respective provider.

Key Points to Remember:

  • Azure and Google Cloud offer service credit when you sign-up.
  • Google Cloud offers $300 as credit to use it for any Google Cloud Platform service. Your 12-month free trial will end early if you spend all $300 of credit before 12 months.
  • Azure offers $200 credit when you sign-up and this can be spent during the first 30 days. However, spending all the credit will not end your free trial.

What are the Free Tier restrictions on AWS, Azure and Google Cloud?

The Free Tier services mentioned above have time restrictions of up to 12 months for the users signing up for the first time and usage limitations per month. These are the restrictions that come as “the name suggests” but these are not the only ones and others can typically apply too.

Here are the other restrictions that Free Tiers are generally equipped with:

Operational limits:

Free Tier services are offered with defined limitations that can only be exempted when you switch to the paid version.

Software and Operating Systems:

The commercial software and operating systems are generally not included under Free Tier. It seems fair as the software and OS give the user exclusive control to meet their demands that should be actually paid.

Rollovers are prohibited:

The limitations are defined typically for monthly usage, if you do not use what is offered in a given month, the usage won’t be carried forward to next month. Well, here is an pro tip if you really want to get an idea of the service, please use it within the month as it is an ideal timeline for experiments.
