As already mentioned we followed the informa- tion systems prototyping approach. Our con- clusion is that it was the right choice and we have shown the advantages of cloud services in modern LMS. We have briefly described a num- ber of functional components of a modern LMS based on cloud services. Of course, the num- ber of such components is not limited to just the few described here. Cloud services are also used in order to share course calendars, educa- tional picture galleries and access to social net- work components such as blogs, Facebook and Twitter. One of the rather popular applications of blogs and Twitter in LMS is providing live news feeds for students. The number of applica- tions of modern cloud services will significantly grow in the near future. The advantage of using such services is obvious. Cloud services pro- vide a very convenient environment for editing, uploading and downloading content. For exam- ple, as it was mentioned earlier, Dropbox can be simply synchronized with the local file system and thus editing of remote materials becomes equal to editing local materials. Editing of pic- ture galleries such as Picasa and Facebook can be done directly as you make snapshots on your mobile device. Introducing cloud services into the daily work of teachers spares them tedious work for uploading and upgrading materials for students. At the same time, the use of cloud services faces serious obstacles from technical and legal perspectives.
