Increased read throughput, better load distribution and higher availability can be achieved by distributing multiple Secondaries across availability zones in AuraDB. You can easily scale Secondaries as your workload requirements change, with options to manage them via the Aura Console or API. The Secondary count is retained when pausing and resuming a database, allowing for seamless setup maintenance without reconfiguration. However, it's essential to consider configuration limitations, including static Secondaries that don't support elastic scaling, and region restrictions, which require all instance and secondary components to be in the same cloud region.
