There are several reasons why businesses migrate their operations to the cloud. Scalability and price are among the most important factors determining this transition. Unlike legacy systems, cloud based businesses can scale on demand. The database and applications in the cloud are not rendered simply from one server located in your headquarters, but is instead distributed across several servers across the world. Such CDNs also bring about greater control in times of uncertainty. A database hack can be easily averted by shutting down the breached server and only rendering from servers that are still secure.
