Amazon FSx for OpenZFS now supports highly available (HA) Single-AZ deployments, offering high availability and consistent sub-millisecond latencies for use cases like data analytics, machine learning, and semiconductor chip design that can benefit from high availability but do not require multi-zone resiliency. Single-AZ HA file systems provide a lower-latency and lower-cost storage option than Multi-AZ file systems for these use cases, while offering all the same data management capabilities and features. Before today, FSx for OpenZFS offered Single-AZ non-HA file systems, which provide sub-millisecond read and write latencies, and Multi-AZ file systems, which provide high availability and durability by replicating data synchronously across AZs. With Single-AZ HA file systems, customers can now achieve both high availability and consistent sub-millisecond latencies at a lower cost relative to Multi-AZ file systems for workloads such as data analytics, machine learning, and semicondu...
