Portability may refer to data portability or architecture portability. Data portability is focused on the ability to move data between traditional and cloud services or between different cloud services without having to port the data under challenging and lossy methods or significant changes to either service or the loss of metadata.

Data portability matters to an organization that uses a multicloud approach, as data moves between vendors. Each move cannot create a data porting exercise, or it is not seamless or useful. It is also important in a loud bursting scenario, where peak usage expands into a cloud environment and then shrinks back to its original noncloud size. This must be seamless to make the strategy useful. Data backups are increasingly to the cloud, and a restore to in-house servers must be handled easily.

Architecture portability is concerned with the ability to access and run a cloud service from a wide variety of devices, running different operating systems. This allows users on a Windows laptop and a MacBook Pro to use the same application services, share the same data, and collaborate easily.
