Final answer:
To transfer 60 TB of data cost-effectively from AWS to an on-premises location monthly, AWS Snowball is the most suitable solution, offering secure and efficient physical data transport to satisfy compliance requirements.
Step-by-step explanation:
The most cost-effective way to transfer 60 TB of data monthly from AWS to an on-premises location for a satellite image processing company is likely through the use of AWS Snowball or a similar data transport solution provided by Amazon Web Services. AWS Snowball is a data transport service that uses physical devices to transfer large amounts of data into and out of AWS with lesser bandwidth costs compared to high-volume data transfer over the internet.
With 60 TB of data to transfer, using Snowball can help the company avoid high network costs and ensure data is moved efficiently. The device is shipped to the customer, loaded with data, and then returned to AWS to have the data transferred to the customer's on-premises data center. This method is not only cost-efficient but also secure, as the Snowball devices have robust encryption for data safety during transport.Since the company's requirement is to transfer data once a month, this method seems practical for compliance purposes without incurring excessive costs due to the large volume of data involved.
