Pros and Cons of a multi-cloud strategy

Instead of sticking to one cloud vendor (such as microsoft or amazon), there is now the option for multi-cloud. 

These are layers of software, such as containers and micro-services, which can sit on top of different cloud provider's APIs, so that developers can write their applications once, with a uniform interface, and deploy them on multiple clouds without having to make and support vendor-dependent modifications.  

The advantage is flexibility—you aren't tied to one cloud vendor. A major con is that, since multi-cloud tech is evolving so fast, you can be left with a skills gap if you can't retain talent.
