A streaming service runs workloads in both AWS and Azure. What is this strategy called?

This strategy is called multi-cloud because it involves using services from more than one cloud provider (in this case, AWS and Azure). Multi-cloud offers benefits like increased resilience, avoiding vendor lock-in, and leveraging best-of-breed services from different providers. Hybrid cloud refers to a mix of on-premises infrastructure and at least one public cloud. Vertical scaling (scaling up) involves increasing the resources of a single server or instance, not a cloud strategy. Edge computing involves processing data closer to the source of data generation, often outside traditional data centers or cloud environments.
