Businesses are rapidly adopting multi-cloud strategies to adapt to changing markets, driven by increasing AI usage. A survey found that 39% of companies prioritize AI/ML, requiring additional cloud providers. Multi-cloud allows businesses to use various public and private clouds or a combination to run their apps and services.

Multi-cloud offers advantages such as resilience, flexibility, and compliance with data regulations. It enables companies to leverage unique services from different cloud providers to enhance their applications.
