In this post, we dive deep into the Aurora backup architecture, how it differs from Amazon RDS backups, and the Amazon CloudWatch metrics available to monitor your backup storage usage. Through detailed scenarios and visualizations, we demonstrate how workload patterns and retention periods impact backup costs. We also explore cross-Region backup options and share recommended practices to optimize your backup storage consumption.

In Part 1, Part 2, and Part 3 of this series, we explored PostgreSQL’s native indexes (B-tree, GIN, GiST, HASH, BRIN) and specialized extension-based index types (SP-GiST, btree_gin, btree_gist). In this post, we dive into three additional extensions: Bloom (for space-efficient multi-column equality filtering), pg_trgm (for fuzzy text matching and similarity searches), and pg_bigm (for full-text search optimized for Asian languages)

In this post, the third in the series, we dive into three extension-based index types: SP-GiST, btree_gin, and btree_gist. These are available in Amazon Aurora PostgreSQL-Compatible Edition and Amazon Relational Database Service (Amazon RDS) for PostgreSQL. PostgreSQL’s index infrastructure is extensible. Operator classes define how indexes behave for specific data types and operations. The SP-GiST, btree_gin, and btree_gist extensions take advantage of this extensibility to give you additional indexing strategies beyond the native options. We walk through when to use each extension, the data types they support, and practical examples that demonstrate their performance benefits.

In this post, we demonstrate how to implement a production-ready CDC solution by using Amazon Aurora for PostgreSQL, Debezium connectors, and Amazon Managed Streaming for Apache Kafka (Amazon MSK). This solution captures database changes in real time and streams them to Kafka topics so that downstream consumers can process the same data for different business purposes.

In this post, we introduce a modular Terraform template, published in the aws-samples/sample-rds-db2-tools repository, that lets your applications keep their existing custom domain names and ports while preserving end-to-end TLS encryption to Amazon RDS for Db2. The template deploys a Server Name Indication (SNI) based TLS proxy that forwards encrypted traffic without ever decrypting it.

Customers running IBM Db2 workloads often ask for a repeatable, auditable way to provision Amazon RDS for Db2 that fits their existing infrastructure-as-code practice. In this post, we introduce a modular Terraform template, published in the aws-samples/sample-rds-db2-tools repository. The template takes you from an empty AWS account to a running RDS for Db2 instance tracked in AWS License Manager in under an hour.

In this post, we walk through how Gremlinq works, demonstrate its capabilities, show you how to set up a Neptune project with the provided templates, and help you understand where this approach might fit in your development context.

In this post, we walk through the available options for sharing Oracle Database@AWS (ODB@AWS) resources across AWS accounts. We also cover common cross-account architecture patterns, along with best practices and key considerations. This helps you design your ODB@AWS architecture across your AWS accounts efficiently.

In this post, we show you how to build a multi-Region Kerberos authentication system that matches your Aurora Global Database’s resilience using AWS Directory Service for Microsoft Active Directory (AWS Managed Microsoft AD) with multi-Region replication and a one-way forest trust to your on-premises Active Directory, so your Linux clients can authenticate without joining the AD domain.

Oracle Database@AWS (ODB@AWS) delivers Oracle Exadata infrastructure, managed by Oracle Cloud Infrastructure (OCI), directly within Amazon Web Services (AWS) data centers. In this post, we walk you through the backup and recovery options available for ODB@AWS services: Oracle Exadata Database Service on Dedicated Infrastructure (ExaDB-D) and Oracle Autonomous AI Database on Dedicated Exadata Infrastructure (ADB-D).
