Transfer Large Amounts of Data to AWS

Answer - B.

AWS Direct Connect makes it easy to establish a dedicated network connection from your premises to AWS.

Using AWS Direct Connect, you can establish private connectivity between AWS and your datacenter, office, or colocation environment, which in many cases can increase bandwidth throughput, and provide a more consistent network experience than Internet-based connections.

The company is concerned about the transfer of large amounts of data required by their data application, which is running on-premises and needs to be transferred to a VPC containing EC2 instances in an AWS region. As the data being transferred is new data every time, the company needs suggestions to transfer the data efficiently.

A. Provision a VPN connection between the on-premise data center and the AWS region using the VPN section of a VPC.

Using a VPN connection is a good option to securely transfer data between on-premises and AWS. However, a VPN connection can have limitations in terms of bandwidth and latency. If the amount of data being transferred is large, it may not be the most efficient solution.

B. Suggest provisioning a Direct Connect connection between the on-premise data center and the AWS region.

Direct Connect is a dedicated network connection between the on-premises data center and AWS, which provides a high-bandwidth, low-latency connection. Direct Connect is a better option than VPN for large data transfers, but it can be more expensive.

C. Suggest using AWS import/export to transfer the TBs of data while synchronizing the new data as it arrives.

AWS Import/Export is a service that allows you to transfer large amounts of data to and from AWS using portable storage devices, such as external hard drives. This option is suitable when the data is in TBs, and the time required to transfer data over the network is impractical. This service can be automated to synchronize new data as it arrives.

D. Suggest leaving the data required for the application on-premise and use a VPN to query the on-premise database data from EC2 when required.

This option can work if the amount of data required for the application is not large, and the application does not require real-time access to the data. However, if the data is required frequently and in real-time, this option can result in network latency and potentially affect application performance.

In conclusion, based on the scenario given, the most efficient option to transfer large amounts of data would be to use Direct Connect. However, if the amount of data is impractical to transfer over the network, AWS Import/Export can be used to transfer data.
