Aurora Scale Versus ClustrixDB Scale
Matching the performance of a high-transaction, high-value workload to the right database is critical. Different database products use different techniques to increase performance, and different techniques can lead to extra work and extra cost for customers. Here, we'll take a closer look at Clustrix scale versus Aurora scale.
Aurora and MySQL are scale-up database products. Scale-up databases are designed to run on a single instance (or node), and customers can increase performance by migrating to a larger, faster, and typically more expensive instance. Once scale-up databases are running on the largest available hardware, the process of increasing performance moves to adding read slaves and/or sharding—techniques that are expensive to implement and maintain, add fragility, and do little to scale the write performance of the database workload.
ClustrixDB is a true scale-out database. Scale-out databases are designed to run on a cluster of affordable instances (typically three or more) and provide performance and reliability appropriate for use with high-transaction, high-value workloads. Scale-out databases are immune to any single point of failure and can scale both reads and writes in a near-linear fashion. And the ClustrixDB Rebalancer feature is constantly evaluating and balancing the distribution of data across the cluster to ensure optimal performance.
Scale-out databases are particularly well suited for mixed workloads where there is normal online transactional processing (OLTP) running concurrently with report creation and even some business analytics. The increased demands of a mixed workload have traditionally overwhelmed scale-up databases like MySQL and Aurora, but they are not a problem for ClustrixDB.
