The database is behind the scenes giving your online store great performance, storing your customer data and all the important information about purchases. Thus, it’s a service that needs to be done for your business to function properly.
Wouldn’t it be great then if the database would work precisely adjusted for the highest level of performance of your Magento store without the need for you to be manually modifying configurations and doing time-consuming administrative tasks? Now Amazon Aurora supports Auto Scaling for Aurora Replicas, and you can ensure that the desired number of Amazon Aurora replicas are run at any given time and condition so your database can keep up with the increasing demands of your application.
It works in the following way, Aurora automatically increases the number of replicas when demand increases during traffic jumps, or on schedule to maintain performance and availability, and decreases capacity during off hours to reduce costs. This feature makes your database cheaper and more efficient, and it frees you to focus on your business.
