These mostly are dependent on the provider. The first being the security of files stored ie. If they are stored in America or in the EU with a ‘safe harbour’ agreement. Additional to this, moving to cloud computing may lock us in to that provider, meaning if they are unable to advance effectively, it may allow our competitors to progress further than ourselves. Also reliability is essential and any potential cloud provider would need to ensure they had distributed systems to ensure if a server failure occurred our company would not come to a standstill. Some vendors do allow options to export data and back this up, however if we were to store the data on our own servers also, this would minimise the actual cost savings and almost nullify the need for cloud computing. The most important risk is that cloud computing is completely dependent on internet connection, and any internet failures would result in us having no access to programs or data required. Compatibility would also be an area to check with any prospective provider, standards would need to be in place with any cloud based software used to ensure our clients would still be able to read any information sent to them using the Microsoft platform. I would not advise moving to a cloud computing system. This is mostly due to the reliability risks described above. If cloud computing were used, I would recommend data be backed up in-case of server failure or internet connection
