Large organizations often prefer to have options and not be tied to a single provider. The risk is often too great, because the provider may shut down or be unable to provide the same level of service. Having multiple providers is often good for negotiating prices, too. Kubernetes is designed to be vendor-agnostic. You can run it on different cloud platforms, private service providers, and on-premises data centers.

However, this is not trivial. If you want to be sure that you are able to switch providers quickly or shift some workloads from one provider to the next, you should already be running your system on multiple providers. You can do it yourself or there are some companies that provide the service of running Kubernetes transparently on multiple providers. Since different providers run different data centers, you automatically get some redundancy and protection from vendor-wide outages.
