Microsoft has revealed that its SkyDrive cloud service has reached 250 million users, 50 million of whom have joined since the launch of Windows 8 in October 2012. The news comes after the Redmond-based company announced 700 million Microsoft accounts in April, as it added two-step verification to make accounts more safe. 

SkyDrive was initially introduced in 2007 and has since grown into a cloud storage area that allows users to upload and sync files from the web or a slew of devices. Users get 7GB of free storage and access to online versions of Microsoft Office, offering similar collaboration to what is present over on Google Drive.

It's worth noting that SkyDrive integration comes within Windows 8 and several Windows Phone 8 handsets, requiring you to sign into a SkyDrive account when also signing into your Microsoft accounts. Microsoft isn't clear about how many users are active on SkyDrive, simply saying: "Over 250 million people are now using SkyDrive as the new place to save their files."

On its Q2 2013 conference call in April, Apple announced its iCloud has reached 300 million users, a 20 per cent increase in the second quarter, up from 250 million iCloud users on the service in January and 150 million in July 2012Apple further added it will expand on the file synchronisation service with new features in the near future, though the company didn't go into the specifics.

Along with its SkyDrive accomplishment, Microsoft on Monday released an infographic detailing some of SkyDrive's accomplishment. Most notably, one billion Office documents have been uploaded to SkyDrive. The company further bragged about its SkyDrive apps available on Windows, Mac, Windows Phone, Android and iOS, and the new look it got in August 2012 that also included Facebook Chat integration.

While 250 million users is certainly an accomplishment, increased competition from Dropbox, Google Drive and iCloud will keep the SkyDrive team on its toes.
