A multi-cloud strategy involves using multiple cloud services from different providers to meet various business needs. Key features include enhanced flexibility, allowing organizations to select the best service for each task, and improved resilience, as relying on multiple providers minimizes downtime in case of a single provider failure. It also can lead to potential cost savings through competitive pricing and enable access to unique features offered by different platforms. However, managing a multi-cloud environment requires careful planning and integration efforts to ensure efficiency and security.
