As a Cloud Architect, you need to design a resilient system for handling streaming data, ensuring regional failure resistance and a 7-day retention of streaming logs. What is the most suitable GCP architecture for this purpose?

*Explanation: The ideal solution in this scenario is to use Cloud Pub/Sub with a multi-region endpoint, combined with a message retention policy within Cloud Pub/Sub. This configuration ensures high availability and resilience against regional failures, which is vital for a system handling streaming data. The multi-region endpoint of Cloud Pub/Sub provides the necessary robustness, while the retention policy allows for the storage of streaming logs for up to 7 days. This setup is more efficient and reliable for handling streaming data compared to alternatives like single-region endpoints or using other storage services like Cloud Spanner or Cloud Bigtable, which may not offer the same level of regional resilience or appropriate data retention capabilities for this specific use case.*
