Yandex offers Disk, a service for storing and sharing files. The Yandex.Disk API enables programmatic access and retrieval of these files from any device connected to the internet. This API can be programmed to be accessed from a Windows PC, phone or tablet by utilizing the Yandex.Disk C#/.NET SDK working within Visual Studio projects.
As the world shifts to computing on the cloud , or what my non tech friends call, lots of servers connected to the internet, APIs become increasingly the lingua franca or working language to communicate to and fro from these clouds. Storage in the cloud has been of the earliest use cases and one which has increasingly made sense to create secure backups at a much cheaper rate.
