We’re happy to announce that Amazon OpenSearch Ingestion pipelines can now read from S3 buckets in different Regions to ingest and consolidate data into a single OpenSearch Service domain or collection. In this post, I’ll show you how to use the new cross-Region support to ingest data from S3 buckets across multiple AWS Regions into a single OpenSearch Service domain or collection.

In this post, we discuss how you can use Precisely Connect to enable real-time, direct replication of mainframe data to Amazon Simple Storage Service (Amazon S3), and how your organization can extend this foundation using Amazon S3 Tables for advanced analytics.

In this post, we walk through installing the Power and Skill, using Amazon Kinesis Data Streams to build a Kinesis Data Stream-to-Kinesis Data Stream streaming pipeline, and migrating an existing application to Flink 2.2. You can follow along with this use case to see how the Managed Service for Apache Flink Kiro Power can help you build a resilient, performant application grounded in best practices.

In this post, we provide an approach to reuse your existing client certificates without reissuing them through AWS Certificate Manager (ACM) Private Certificate Authority. This solution enables an accelerated migration path by using your current third-party CA infrastructure. This removes the complexity and operational overhead of certificate re-issuance while maintaining the security posture that you’ve established with your existing mTLS implementation.

In our previous post, A guide to Airflow worker pool optimization in Amazon MWAA, we explored when adding workers to your Amazon Managed Workflows for Apache Airflow (Amazon MWAA) environment actually solves performance issues, and when it doesn’t. We walked through patterns like high CPU utilization and long queue times where scaling may be appropriate, […]

Optimizing the Airflow worker pool configuration in Amazon Managed Workflows for Apache Airflow (Amazon MWAA), the AWS fully managed Apache Airflow service, is an important yet often overlooked strategy for scaling workflow operations. Tasks queued for longer periods can create the illusion that additional workers are the solution, when in reality the root cause might […]

Amazon OpenSearch Service now brings application monitoring, native Amazon Managed Service for Prometheus integration, and AI agent tracing together in OpenSearch UI’s observability workspace. In this post, we walk through two real-world scenarios using the OpenTelemetry sample app: a multi-agent travel planner facing slow processing, and a checkout flow quietly failing on one microservice.

In this post, we explain what’s new in Amazon Managed Service for Apache Flink 2.2, provide a guided migration using CLI commands, console instructions, and code examples, and show you how to monitor the upgrade and roll back if needed.

In this post, we explore how to use Apache Sedona with AWS Glue to process and analyze massive geospatial datasets.

In this post, we demonstrate how to use the metadata export capability in Amazon SageMaker Catalog and perform analytics such as historical changes, monitor asset growth and track metadata improvements.
