There aren’t many disadvantages to Cloud computing and most of them are far outweighed by the positive benefits. Yes, it’s a service that you’ll have to pay for, but you have to pay to run in-house systems too and Cloud computing is likely to save you money in the long run. Yes, Cloud hosts sometimes have a problem that results in downtime, but they have the resources and infrastructure to get things fixed quickly – probably more quickly than if you had to fix a computer issue with your own in-house team. Finally, yes, there is a theoretical security risk. This is true because nobody anywhere can guarantee there is absolutely no risk of theft or hacking. But Cloud hosts have physical and digital security in place that is far more robust than any you would be likely to have locally.
