The term multicloud is one of the more overused terms in IT circles today. At its most basic level, any customer that uses more than one cloud service could be considered multicloud. But that’s not really multicloud, that’s just using multiple clouds. True multicloud should enable businesses to use some combination of private and public clouds, but operationally it would look like a single cloud domain.
There’s not one well-defined path to multicloud. In fact, there shouldn’t be. Every business is different, which means everyone needs options. Some will migrate quickly, some slowly, some will forklift upgrade hardware, and others will sweat their assets. The problem with options is that they add to complexity, and that has become public enemy number one of network operations. Network professionals need to worry about managing the underlay, managing overlay, maintaining policies, automating processes, and other factors to make multi-cloud a reality.
