A company is running a batch analysis every hour on their main transactional DB running on an RDS MySQL instance to populate their central Data Warehouse running on Redshift. During the execution of the batch their transactional applications are very slow. When the batch completes they need to update the top management dashboard with the new data. The dashboard is produced by another system running on-premises that is currently started when a manually-sent email notifies that an update is required The on-premises system cannot be modified because is managed by another team. How would you optimize this scenario to solve performance issues and automate the process as much as possible?

AReplace RDS with Redshift for the batch analysis and SNS to notify the on-premises system to update the dashboard

BReplace RDS with Redshift for the batch analysis and SQS to send a message to the on-premises system to update the dashboard

CCreate an RDS Read Replica for the batch analysis and SNS to notify me on-premises system to update the dashboard

Absolutely, Option B is the winner here. Automating the process as much as possible is key, and SQS provides a nice, hands-off way to make that happen. No more relying on the human element!

Haha, imagine the poor person in charge of that email notification. They'll probably end up setting a calendar reminder to remember to hit 'send' every hour. Option B is definitely the way to go.

I see your point, Herminia. But I think option D might be the most practical solution as it combines the benefits of using a Read Replica and SQS.

Option B seems the best approach here. Using SQS to send a message to the on-premises system is a more reliable and automated way to trigger the dashboard update, rather than relying on a manual email notification.

I think option A is the best choice because Redshift is optimized for analytics and SNS can easily notify the on-premises system.
