A reference architecture for multicloud


Today’s definition of multicloud depends on who you ask. This is not a new trend. Whenever a new technology gets some hype, suddenly there is semantic confusion. 

My definition is a bit more holistic than most: Multicloud is a collection of public clouds, private clouds, and legacy systems (yes, I went there). Two or more public or private clouds must be present to be true multicloud. Legacy systems are optional but also good to include.

A charted representation of my definition looks like this:

Something I’ve learned over the years is that frameworks of any kind have to be generic and applicable to different problem domains. My representation includes most of what you’ll find in common multicloud deployments I see today. 

If this seems complex, that’s the point. If the goal is to get a healthy multicloud deployment up and running, you’ll need most of these services. That list includes everything from cost governance, storage management, and cloud service brokers, as well as orchestration and process management—and those skills require qualified talent.

You’ll need a few more things, depending on your industry, such as compliance management. Figure on at least 20 percent to 30 percent more services to ultimately meet your business needs.
