The promise of cloud computing Cloud computing refers to a network that distributes processing power, applications, and large systems among many computers. Social media channels and many other applications use cloud computing as their platform. But cloud computing goes beyond that, offering a way for people to expand their local computing power onto the (seemingly) infinite processing power of the Internet. One of the results is a changing method of communication. Cloud computing can be a single-function application, an infrastructure on which these applications (and many others) can run, a set of services that offer the advantages of huge amounts of computing resources, and the ability to store large amounts of data remotely. Many companies and educational institutions are just beginning to realize the benefits of cloud-based applications that have traditionally required site licensing, installation, and maintenance. Cloud computing seems to offer some incredible benefits for communicators: the availability of an incredible array of software applications, access to lightning-quick processing power, unlimited storage, and the ability to easily share and process information. All of this is any time you can access the Internet. While this might all appear enticing, there remain issues of reliability, portability, privacy, and security.
