Multi-cloud refers to the strategic use of cloud services from two or more distinct cloud providers, such as AWS, Azure, or Google Cloud. This approach involves leveraging different cloud platforms for various workloads or applications, rather than relying on a single vendor. Organizations implement multi-cloud strategies to avoid vendor lock-in, enhance resilience through redundancy, and optimize costs by selecting the best services for specific needs. For instance, a company might use AWS for its machine learning capabilities and Azure for its strong enterprise integration. It is important to distinguish multi-cloud from hybrid cloud, which combines public cloud services with private infrastructure. Understanding multi-cloud is crucial for roles preparing for certifications like CCSP and AWS SAA.
