[All Professional Cloud Architect Questions]

Your company wants to migrate their 10-TB on-premises database export into Cloud Storage You want to minimize the time it takes to complete this activity, the overall cost and database load The bandwidth between the on-premises environment and Google Cloud is 1 Gbps You want to follow Google-recommended practices What should you do?

AUse the Data Transfer appliance to perform an offline migration

BUse a commercial partner ETL solution to extract the data from the on-premises database and upload it into Cloud Storage

CDevelop a Dataflow job to read data directly from the database and write it into Cloud Storage

DCompress the data and upload it with gsutii -m to enable multi-threaded copy

Show Suggested Answer

Suggested Answer: A

The Data Transfer appliance is a Google-provided hardware device that can be used to transfer large amounts of data from on-premises environments to Cloud Storage. It is suitable for scenarios where the bandwidth between the on-premises environment and Google Cloud is low or insufficient, and the data size is large. The Data Transfer appliance can minimize the time it takes to complete the migration, the overall cost and database load, by avoiding network bottlenecks and reducing bandwidth consumption. The Data Transfer appliance also encrypts the data at rest and in transit, ensuring data security and privacy. The other options are not optimal for this scenario, because they either require a high-bandwidth network connection (B, C, D), or incur additional costs and complexity (B, C). Reference:

I'm with Cheryl on this one. Dataflow is the way to go. It's fast, efficient, and you can't beat Google's recommended practices. Although, I do wonder if they'll give us a free Data Transfer appliance as a reward for choosing the 'right' answer.

Haha, Claribel, Dataflow may be a bit more complex, but it's probably worth it for a 10-TB migration. Plus, who doesn't love some good old-fashioned 'cloud magic'?

Hmm, I'm not sure about Dataflow. Isn't that thing a bit complicated? I'm leaning more towards Option D - compressing the data and using gsutil seems straightforward and should get the job done.

Yeah, compressing the data and using gsutil sounds like a good plan.

I agree, Dataflow seems like the way to go. It's a Google-recommended practice and will probably be the most cost-effective solution for a 10-TB migration.

Option C looks like the best choice here. A Dataflow job can directly read from the database and write to Cloud Storage, which should be faster and more efficient than the other options.

Yes, using a Dataflow job to read data directly from the database and write it into Cloud Storage should help minimize the time and cost of the migration.
