Cloud computing increases website performance by sharing system resources across multiple servers. The technology has the potential to outdate any previous technologies. Basically, its many connected servers transfering encrypted files and data resources across each other. Older tech stores all the files and data at on place on one server. In some cases this is more than adequate. However, if your needs require high end load requirements than cloud is the only way to go. High end loads get divided into more and more servers resulting in faster website performance. Also, cloud computing results in fewer downtimes by alleviating issues due to a server bug or hacker session by sending the buged server query to another issue free server. These transfers are seamless with no drop in load times. Scalability is accomplished with a call an API or other interface.
