Teachme Biz uses Amazon Web Service (AWS) as its data center.
The shared responsibility model applies between AWS and our company, and security responsibilities for cloud service provision are shared between AWS and our company.
For example, AWS is responsible for operating and managing physical security at facilities where the service runs, while our company is responsible for the applications running on it and security configurations.

We have confirmed that the above shared responsibility model can fulfill the requirements of our terms of service, and have concluded a contract accordingly.
