Description: Cloud architecture refers to the structure and design of the components that make up a cloud computing environment. This architecture enables the delivery of computing services over the Internet, facilitating access to resources such as storage, processing, and networking. In the context of multi-cloud, it refers to the use of multiple cloud service providers to optimize flexibility, scalability, and resilience of applications. Key features of cloud architecture include virtualization, which allows the creation of independent virtual environments; automation, which facilitates resource management; and security, which protects data and applications in the cloud. Cloud architecture is also based on design principles such as modularity and interoperability, allowing organizations to efficiently integrate different services and platforms. In a multi-cloud environment, companies can choose and combine services from different providers, enabling them to avoid reliance on a single provider and optimize costs and performance. This flexibility is especially valuable in a world where business needs change rapidly and the ability to adapt to new technologies and market demands is crucial.
