• Tune Lambda, Azure Functions, and GCP Cloud Functions.
• Configure auto-scaling triggers for demand.
• Monitor performance with CloudWatch.
• Test with sample events.
• Automate with Ansible for scalability.

This ensures scalable serverless applications across clouds.

201. How do you optimize multi-cloud storage latency?

• Enable transfer acceleration in S3, Azure Blob, and GCP Storage.
• Monitor latency with CloudWatch.
• Optimize access patterns for speed.
• Test with aws s3 cp.
• Automate with Ansible for performance.

This reduces storage latency across clouds.

202. How do you optimize multi-cloud for high-performance computing?

High-performance computing requires optimized resources. Use AWS HPC instances, Azure HPC VMs, and GCP Compute-Optimized VMs. Monitor with CloudWatch and automate with Ansible to ensure efficient compute performance for demanding workloads across multi-cloud environments.

203. How do you optimize multi-cloud workload distribution?

• Use Kubernetes for orchestration across EKS, AKS, and GKE.
• Configure load balancing for even distribution.
• Monitor workloads with Prometheus.
• Test distribution with load simulations.
• Automate with Ansible for balance.

This ensures balanced workload performance across clouds.
