Cloud computing is a model for delivering computing resources and services over the internet on a pay-per-use basis. Instead of running applications and storing data on local servers or personal devices, users can access these resources from remote data centers managed by cloud service providers.

Multi-cloud is a strategy where an organization uses multiple cloud computing services from different vendors. This can include using multiple public cloud services, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform, as well as a combination of public and private clouds.

Multi-cloud strategies offer organizations greater flexibility, scalability, and cost savings, as they can select the best-suited cloud services for different workloads and use cases. They can also minimize vendor lock-in and ensure business continuity in the event of a service disruption with one provider.

Cloud computing and multi-cloud strategies are transforming the way organizations do business, allowing them to access and scale computing resources on demand, increase collaboration and productivity, and reduce capital and operational costs.
