Amazon Aurora now supports PostgreSQL major version 18

Amazon Aurora PostgreSQL-Compatible Edition now supports PostgreSQL major version 18, starting with version 18.3. This release brings community improvements to query performance and database management, and introduces support for pg_roaringbitmap, a new extension that performs fast, memory-efficient set operations on large collections of integers. This enables use cases such as audience segmentation, tag-based filtering, and permission checks directly in the database without application-layer processing. PostgreSQL 18 introduces B-tree skip scans, which improve query performance, and reduce index storage and maintenance overhead. Major version upgrades now retain optimizer statistics, ensuring consistent query performance immediately after upgrading without waiting for statistics to be regenerated. Logical replication can now stream large transactions in parallel, reducing replication lag and keeping downstream systems more current. Please refer to the Amazon Aurora PostgreSQL release notes for details. You can upgrade your database using several options including RDS Blue/Green deployments, upgrade in-place, or restoring a snapshot. Learn more about upgrading your database instances in the Amazon Aurora User Guide. Aurora PostgreSQL 18.3 is available in all commercial AWS Regions and AWS GovCloud (US) Regions. Amazon Aurora is designed for unparalleled high performance and availability at global scale with full PostgreSQL and MySQL compatibility. It provides built-in security, continuous backups, serverless compute, up to 15 read replicas, automated multi-Region replication, and integrations with other AWS services.

Amazon CloudWatch Application Signals now supports infrastructure, logs, and traces context for faster troubleshooting

Amazon CloudWatch Application Signals introduces service health ranking on the application map and new infrastructure, logs, and traces tabs on the service overview page. These capabilities let operators triage unhealthy services and inspect the underlying compute environment, log snippets, and trace details in one place, making it easier to find root causes without switching tools. Customers use Application Signals to monitor the health of distributed applications, but identifying why a service was unhealthy often required leaving CloudWatch to correlate infrastructure data across separate tools. The application map now ranks services by health and shows runtime indicators on service nodes for Amazon EKS, Amazon ECS, AWS Lambda, and Amazon EC2, along with a new infrastructure tab that surfaces the compute and runtime environment, its components, and curated default metrics with deep links to the relevant monitoring tools. In addition, the service overview page provides the infrastructure, logs, and traces tab, helping operators spot issues in context of their application. With health-ranked services on the application map and new infrastructure, logs, and traces tabs, operators can instantly identify their most degraded services and drill into the compute environment, error-producing log snippets, and slow or failing transactions — all without leaving Application Signals. These capabilities span workloads running on Amazon EKS, Amazon ECS, AWS Lambda, and Amazon EC2, giving teams a single pane to move from symptom to root cause in minutes instead of hours. These capabilities are available in all AWS Regions where Amazon CloudWatch Application Signals is supported.
