These days I hear a lot about the goal to run federated applications across cloud providers. We want to build these multicloud applications for many reasons, including:
- To optimize the underlying cloud resources for the application components. For instance, a CPU-intensive portion of the application can run on a portion of a cloud service that provides the fastest processing at the lowest cost for usage.
- To gain the ultimate resiliency, considering that outages typically don’t span cloud providers. Thus, we’re spreading the risk over more than a single provider.
- To avoid lock-in. Now we can put our eggs in many different baskets with a focus on the higher-level abstracted platforms versus the walled gardens of public cloud providers.
