Businesses are adopting multi-cloud and hybrid cloud strategies to improve performance and resilience. Key reasons include avoiding vendor lock-in by diversifying cloud providers, enhancing disaster recovery through distributed cloud environments, and optimizing costs and performance by selecting cloud platforms based on specific workload needs.

AI enhances cloud management by automating workload optimization, predicting demand fluctuations, and improving security. It analyzes real-time data to dynamically adjust resource allocation, provides predictive analytics to optimize cloud spending, and detects cyber threats before they impact operations.

Zero Trust Architecture (ZTA) operates on the principle of 'never trust, always verify,' requiring continuous authentication and authorization for users, devices, and applications. It is important for securing multi-cloud and hybrid cloud infrastructures as it mitigates insider threats, prevents lateral movement of cyber attackers, and strengthens compliance with data privacy laws.
