AWS 的数据传输类型大致有如下三类：

与 Internet 之间的数据传输
AWS 内部跨区域的数据传输
AWS 内部同一区域的数据传输

每个区域从 AWS 到 Internet 的数据传输费率都不一样，基本是 下行免费，上行收费，费率算总量

Background

Workplaces may enforce TOTP 2FA to be enabled Office 365 accounts, which require the Microsoft Authenticator app to be installed.

Regular TOTP applications (such as Aegis, Authy, or LastPass) cannot be used as Microsoft uses a proprietary scheme called phonefactor. Furthermore, the application requires Google Services Framework (GSF) to be installed (likely to provide device notifications), and will refuse to work when it is not present on the device.

Forunately, after the registration is complete, the underlying mechanism the app uses to generate TOTP codes is regular otpauth, and its secrets can be exported with a little bit of effort.
