For an e-commerce application requiring low-latency object retrieval and high durability, with a need to archive transactional data after 30 days, what is the optimal combination of storage classes and data lifecycle policies?

*Choosing Multi-Regional Storage for active data and transitioning to Coldline Storage after 30 days is the best strategy for an e-commerce application that demands low-latency and high durability, along with compliance in archiving transactional data. Multi-Regional Storage offers low latency and high durability, making it suitable for active e-commerce operations. Coldline Storage, being cost-effective for data that is infrequently accessed, is apt for archiving purposes after the specified 30-day period. This approach ensures both operational efficiency and compliance with archiving requirements. In contrast, using Nearline for frequently accessed data or manual movement to Archive Storage introduces potential inefficiencies and risks. Transitioning to Archive Storage after 180 days exceeds the specified compliance requirement, making it a less optimal choice.*
