A consultant is a professional who provides expert advice in a particular area such as software, cloud solutions or any of many other specialized fields.
Simply put, cloud computing is the delivery of computing services—servers, storage, databases, networking, software, analytics and more—over the Internet (“the cloud”).
Computer software is a part of a computer system that consists of data or computer instructions, in contrast to the physical hardware from which the system is built.
