Story #1 - Engineering firm experimenting with SharePoint
An architectural firm in Copenhagen, Denmark, has 3 locations at Denmark and Norway. The file server is currently on site with 7TB of data, but they want to get rid of the file server. There are no official communication channels between the 3 sites, so using a cloud solution to unify the 3 sites makes sense.
They experimented with SharePoint and OneDrive. At first it was good because the integration of OneDrive Windows Explorer makes it easy to access files and folders from SharePoint. Later, however, they ran into problems with the AutoCAD application. One problem is related to file locking, the other to external references within a single file. This is not a SharePoint/OneDrive issue, but rather an application compatibility issue between the CAD and SharePoint applications.
SharePoint storage costs are another issue. If they had put all 7 TB of storage on SharePoint, it would have cost about $1400/month. The company wants less frequently used files to be stored in another system. They want a storage platform/solution that solves the file locking and external referencing problem while providing a way to use lower cost storage services like Amazon S3 and Azure Blob Storage.
