A company with a 50 TB data reporting requirement seeks to migrate data from on-premises to AWS, while minimizing operational overhead. Their data center's bandwidth is fully utilized, preventing network transfer during the data transformation process performed weekly by a custom application. The application will be paused for the migration. Identify the solution that allows data transfer and continued transformation operations in AWS with the least overhead.
Explanation:
The best solution to transfer 50 TB of data with the least operational overhead is to use an AWS Snowball Edge Storage Optimized device (option C). This device is specifically designed for large-scale data migrations and includes high storage capacity. Once the data is copied to the device, using AWS Glue for the transformation job ensures that the task is efficiently managed within the AWS ecosystem. This approach minimizes operational overhead since AWS Glue is fully managed and integrates well with data stored in AWS. Option A (AWS DataSync) is less effective due to the lack of available network bandwidth, and options B and D involve more complex setups and potentially higher operational overhead.
