Amazon OpenSearch Serverless introduces support for Derived Source, a new feature that can help reduce the amount of storage required for your OpenSearch Service collections. With derived source support, you can skip storing source fields and dynamically derive them when required.  With Derived Source, OpenSearch Serverless reconstructs the _source field on the fly using the values already stored in the index, eliminating the need to maintain a separate copy of the original document. This can significantly reduce storage consumption, particularly for time-series and log analytics collections where documents contain many indexed fields. You can enable derived source at the index level when creating or updating index mappings. Derived Source support is available today in all AWS Regions where Amazon OpenSearch Serverless is supported. For more information, see

Amazon Redshift further optimizes the processing of top-k queries (queries with ORDER BY and LIMIT clauses) by intelligently skipping irrelevant data blocks to return results faster, dramatically reducing the amount of data processed. This optimization reorders and efficiently adjusts the data blocks to be read based on the ORDER BY column's min/max values, maintaining only the K most qualifying rows in memory. When the ORDER BY column is sorted or partially sorted, Amazon Redshift now processes only the minimal data blocks needed rather than scanning entire tables, eliminating unnecessary I/O and compute overhead. This enhancement particularly benefits top-k queries when the data permanently stores in descending order (ORDER BY ... DESC LIMIT K) on large tables where qualifying rows are appended at the end of the data storage. Common examples include: Finding the k most recent orders from millions or billio

Today we are announcing the release of the Aurora DSQL Connector for PHP (PDO_PGSQL) that makes it easy to build PHP applications on Aurora DSQL. The PHP Connector streamlines authentication and eliminates security risks associated with traditional user-generated passwords by automatically generating tokens for each connection, ensuring valid tokens are always used while maintaining full compatibility with existing PDO_PGSQL features. The connector handles IAM token generation, SSL configuration, and connection pooling, enabling customers to scale from simple scripts to production workloads without changing their authentication approach. It also provides opt-in optimistic concurrency control (OCC) retry with exponential backoff, custom IAM credential providers, and AWS profile support, making it easier to develop client retry logic and manage AWS credentials. To get started, visit the

Starting today, Amazon Elastic Compute Cloud (Amazon EC2) R8i and R8i-flex instances are available in the AWS GovCloud (US-West) Region. These instances are powered by custom Intel Xeon 6 processors, available only on AWS, delivering the highest performance and fastest memory bandwidth among comparable Intel processors in the cloud. The R8i and R8i-flex instances offer up to 15% better price-performance, and 2.5x more memory bandwidth compared to previous generation Intel-based instances. They deliver 20% higher performance than R7i instances, with even higher gains for specific workloads. They are up to 30% faster for PostgreSQL databases, up to 60% faster for NGINX web applications, and up to 40% faster for AI deep learning recommendation models compared to R7i. R8i-flex, our first memory-optimized Flex instances, are the easiest way to get price performance benefits for a majority of memory-intensive workloads. They offer the most common sizes, from large to 16xlarge, an

Amazon CloudWatch Logs Insights saved queries now support parameters, allowing you to pass values to reusable query templates with placeholders. This eliminates the need to maintain multiple copies of nearly identical queries that differ only in specific values such as log levels, service names, or time intervals. You can define up to 20 parameters in a query, with each parameter supporting optional default values. For example, you can create a single template to query logs by severity level (such as ERROR or WARN) and pass different service names each time you run it. To execute a query with parameters, invoke it using the query name prefixed with $ and pass your parameter values, such as $ErrorsByService(logLevel="ERROR", serviceName="OrderEntry"). You can also use multiple saved queries with parameters together for complex log analysis, significantly reducing query maintenance overhead while improving reusability. Saved queries with parameters are available in a

Starting today, Amazon EC2 M8i and M8i-flex instances are now available in AWS GovCloud (US-West) Region. These instances are powered by custom Intel Xeon 6 processors, available only on AWS, delivering the highest performance and fastest memory bandwidth among comparable Intel processors in the cloud. The M8i and M8i-flex instances offer up to 15% better price-performance, and 2.5x more memory bandwidth compared to previous generation Intel-based instances. They deliver up to 20% better performance than M7i and M7i-flex instances, with even higher gains for specific workloads. The M8i and M8i-flex instances are up to 30% faster for PostgreSQL databases, up to 60% faster for NGINX web applications, and up to 40% faster for AI deep learning recommendation models compared to M7i and M7i-flex instances. M8i-flex are the easiest way to get price performance benefits for a majority of general-purpose workloads like web and application servers, microservices, small and med

AWS IoT Core and AWS IoT Device Management services are now available in the Israel (Tel Aviv) and Europe (Milan) AWS Regions. With this expansion, organizations operating in these regions can better serve their local customers and unlock multiple benefits, including faster response times, stronger data residency controls, and reduced data transfer expenses. AWS IoT Core is a managed cloud service that lets you securely connect billions of Internet of Things (IoT) devices to the cloud and manage them at scale. It routes trillions of messages to IoT devices and AWS endpoints, through bi-directional industry standard protocols, such as MQTT, HTTPS, LoRaWAN (select regions). AWS IoT Device Management allows customers to search, organize, monitor and remotely manage connected devices at scale. With the expansion to these regions, AWS IoT is now available in

Amazon FSx now supports copying file system backups across opt-in Regions (AWS Regions that are disabled by default) for Amazon FSx for Windows File Server, Amazon FSx for Lustre, and Amazon FSx for OpenZFS. This launch makes it easier for customers to meet business continuity, disaster recovery, and compliance requirements by extending cross-Region, cross-account backup and recovery capabilities beyond AWS Regions that are enabled by default. Amazon FSx is a fully managed service that makes it easy and cost-effective to launch, run, and scale feature-rich, high-performance file systems in the AWS Cloud. Opt-in Regions are AWS Regions that are disabled by default, in contrast to regions that are enabled by default. Previously, customers could copy Amazon FSx file system backups across regions enabled by

AWS Elastic Disaster Recovery (AWS DRS) now supports IPv6 for both data replication and control plane connections. Customers operating in IPv6-only or dual-stack network environments can now configure AWS DRS to replicate using IPv6, eliminating the need for IPv4 addresses in their disaster recovery setup. AWS DRS minimizes downtime and data loss with fast, reliable recovery of on-premises and cloud-based applications using affordable storage, minimal compute, and point-in-time recovery. Previously, AWS DRS required IPv4 connectivity for all replication and service communication. Now, customers can set the internet protocol to IPv6 in their replication configuration to use dual-stack endpoints for agent-to-service communication and data replication. This helps customers meet network modernization requirements and enables disaster recovery in environments where IPv4 addresses are unavailable or restricted. Existing replication configurations are not affected and continue to

Amazon Web Services (AWS) is announcing the general availability of Amazon EC2 X8i instances, next-generation memory optimized instances powered by custom Intel Xeon 6 processors available only on AWS.
