What should a solutions architect do to migrate and store the data at the LOWEST cost?
Order AWS Snowball devices to transfer the data. Use a lifecycle policy to transition the files to Amazon S3 Glacier Deep Archive.
Deploy a VPN connection between the data center and Amazon VPC. Use the AWS CLI to copy the data from on premises to Amazon S3 Glacier.
Provision a 500 Mbps AWS Direct Connect connection and transfer the data to Amazon S3. Use a lifecycle policy to transition the files to Amazon S3 Glacier Deep Archive.
Use AWS DataSync to transfer the data and deploy a DataSync agent on premises. Use the DataSync task to copy files from the on-premises NAS storage to Amazon S3 Glacier.
Explanations:
AWS Snowball devices provide a cost-effective solution for transferring large amounts of data without network constraints. Once data is in Amazon S3, lifecycle policies can move it to S3 Glacier Deep Archive, which minimizes storage costs.
A VPN connection over a public internet link is not ideal for this volume of data within the time constraint. Additionally, directly storing data in S3 Glacier without an intermediate step can be complex.
Provisioning a 500 Mbps AWS Direct Connect link would be costly and time-consuming to set up. It is also not necessary for a one-time data transfer, making Snowball a more cost-effective option.
AWS DataSync is designed for ongoing transfers rather than large, one-time migrations of this size. It also incurs transfer costs over the public internet and is not the most economical solution for this use case.
I gauge that the answer is:
Order AWS Snowball devices to transfer the data. Use a lifecycle policy to transition the files to Amazon S3 Glacier Deep Archive.
