问题
I want to host my website (PHP/MySQL) on a cloud platform. For sure, my website is new and I don't think that there will be too much traffic. So, I tried to compare the lowest config costs of cloud services between GCP and AWS. The lowest config cost according Google Cloud Platform pricing calculator is as follows:
- Google Compute Engine (f1-micro): $4.09
- Google Cloud SQL (D0 Instance): $11.30
- Datastore (1GB): $0.18
- Total: $15.57 (For details, have a look on this link: https://goo.gl/wJZikT )
Meanwhile, the lowest config cost according AWS Pricing calculator is:
- Amazon EC2 (t1.micro): $14.64
- Amazon RDS (db.t1.micro with 1GB of storage): $18.42
- Amazon S3: $0.11
- Total: $33.17
(For details, have a look on this link http://goo.gl/Pe7dFt )
My question is: how can it be that there is a big difference in the cost of cloud services between google cloud platform and AWS? Is there any thing wrong in my estimation? If it is the case please share with me a link on the configuration of the minimal configuration on AWS...
Thanks.

2 main reasons for the difference:
- Google micro VM uses a shared core and not a dedicated one. Cores seem to be the most expensive part of a VM if you look at prices for both AWS an GCE
- Google provide their sustained usage discount on a monthly basis (30% effective discount per month), while amazon forces you to commit for a year with upfront payment to get any discount.
Both factors above allow you to have a lower cost for the Google VM.
I have tried VMs on GCE with shared cores and did not have any problems. If you use Google monitoring, you can actually track how much the core being shared is affecting you using the CPU steal metric. This article from stackdriver explain it really well.
Side note: stackdriver has been since acquired by Google and is what Google use for monitoring the VMs.
