Moving apps to cloud computing is not the last thing. 　　Sometimes there are unexpected events that force you to redesign your application, and compliance requirements can create barriers to development, and if your cloud provider does not support low-level network services such as multicast, it can cause bandwidth problems. After you evaluate which applications can run in a public cloud, there are other factors to consider, such as configuration, data migration, and monitoring. When moving an application to cloud computing, there are ...
