Implementing a multicloud provider solution would be the best option to ensure resiliency and meet SLA requirements in the event of a CSP incident. A multicloud provider solution involves using multiple cloud service providers to host and manage different parts of an organization's infrastructure and applications. This approach allows the organization to spread its workloads across multiple providers, providing increased resilience and the ability to continue operations in the event that one provider experiences an incident. In addition, using multiple providers can also help to reduce the risk of vendor lock-in, allowing the organization to more easily switch providers if needed.
