To migrate 5PB of on-premises data to durable long-term storage, what is the most cost-effective method?

1. Use AWS Direct Connect for large transfer speeds.

2. Transfer data using multiple Snowball Edge devices.

3. Upload data directly to Amazon S3 without any intermediate steps.

4. Compress all data before transfer to save costs.

The correct answer is: Transfer data using multiple Snowball Edge devices.

Transferring 5PB of on-premises data to durable long-term storage is a significant undertaking that entails considerations about cost, speed, and feasibility. Utilizing multiple Snowball Edge devices stands out as the most cost-effective method for several reasons. Firstly, AWS Snowball is a physical appliance designed specifically for large-scale data transfer. It facilitates the secure and efficient migration of large datasets to the AWS Cloud. When using Snowball Edge devices, you can transfer substantial amounts of data without relying on a high-bandwidth internet connection, which can be both expensive and time-consuming for large volumes like 5PB. Additionally, the cost associated with shipping Snowball devices is often lower than transferring data over the internet, especially when considering the time it would take to transfer such a vast amount through a typical network link. Moreover, Snowball devices offer built-in storage and processing capabilities, allowing for data compression and deduplication before the actual transfer, thus optimizing the amount of data sent to the cloud and further enhancing cost-effectiveness. In contrast, while AWS Direct Connect may provide large transfer speeds, it involves ongoing costs associated with network management and usage, which can escalate dramatically with such volumes of data. Uploading data directly to Amazon S3 could be feasible
