Select SkySQL topologies are available on both AMD64 and ARM64 hardware architectures.
Prices and available instance sizes differ depending on hardware architectures.
You may find that your workload has better price/performance depending on your choice of hardware architecture.
Hardware architectures used for SkySQL topologies are supported by MariaDB Engineering Policy.
Nodes running in AWS with a ARM64 hardware architecture use AWS Graviton processors.
For information about how to choose a hardware architecture with the SkySQL DBaaS API, see "Hardware Architecture Selections with the SkySQL DBaaS API".
