Aurora I/O-Optimized offers up to 40% cost savings for I/O-intensive applications where I/O charges exceed 25% of the total Aurora database spend.

Amazon IVS now offers developers the ability to monitor the health of live streams with multiple hosts. Hosts are connected to each other using the stage resource, which allows them to exchange audio and video with each other in real time.

These data sources include Postgres, MySQL, Oracle, SQL Server, and Amazon Redshift.

Amazon Connect Contact Lens now provides supervisor alerts on agent performance, enabling businesses to identify contacts (e.g., evaluation score < 50%) that require supervisors follow-up with agents on their team.
