Microsoft Azure allows users to build virtual networks and deliver services on a global level. Microsoft or Linux virtual machines can be created, quickly, with the use of marketplace templates, or from custom machine images. These virtual machines can host apps and services, just as if they resided in a company’s local data center. As well, unlimited managed SQL relational databases are offered through Azure, which saves businesses from the additional expense of buying hardware and software. It also eliminates the need for in-house expertise to administer the databases.
