How PostgreSQL on Azure helps modernize legacy databases

Microsoft is enhancing PostgreSQL to establish it as a high-performance, scalable, and enterprise-ready open database platform, addressing the limitations of legacy systems like Oracle. Many Oracle customers face rising licensing costs, performance bottlenecks, and scalability issues, prompting them to consider migration. Apollo Hospitals successfully migrated from Oracle to Azure Database for PostgreSQL, achieving a 60% reduction in operational costs and a threefold improvement in system performance. Microsoft has introduced an AI-assisted migration tool to simplify the transition from Oracle to PostgreSQL, automating the conversion of schemas and application code. Azure Database for PostgreSQL offers high performance, scalability, and security, with features like v6-series compute SKUs and SSD v2 storage. Azure HorizonDB, a new cloud-native PostgreSQL service, supports extreme performance demands and is designed for real-time analytics. Microsoft is committed to enhancing PostgreSQL as an open-source database for enterprise workloads, enabling organizations to innovate and become more agile.

Netflix Automates RDS PostgreSQL to Aurora PostgreSQL Migration Across 400 Production Clusters

Netflix has developed an internal automation platform to migrate Amazon RDS for PostgreSQL databases to Amazon Aurora PostgreSQL, reducing operational risks and downtime for nearly 400 production clusters. The platform allows service teams to perform migrations through a self-service workflow while ensuring processes like replication validation and rollback safeguards are maintained. Database access is managed through a platform-managed layer using Envoy, which standardizes mutual TLS and abstracts database endpoints, enhancing security and efficiency. The migration process starts with creating an Aurora PostgreSQL cluster as a read replica of the source RDS instance, initialized from a storage snapshot and continuously replaying write-ahead log (WAL) records. Validation checks are performed to ensure the replica can handle peak write throughput before cutover. For change data capture workloads, the system coordinates the state of replication slots and pauses CDC consumers to prevent excessive WAL retention. The Enablement Applications team at Netflix successfully migrated databases for device certification and partner billing workflows, addressing issues like elevated replication lag due to inactive logical replication slots. As replication lag decreases, the system enters a controlled quiescence phase, adjusts security rules, and reboots the source RDS instance. Once all transactions are processed and the Aurora replica is ready, it is promoted to a writable cluster, and traffic is rerouted. Rollback capabilities are prioritized, allowing redirection back to the original RDS instance if validation checks fail or anomalies are detected post-promotion. This setup enables seamless restoration without redeployment, and CDC consumers can resume from recorded slot positions if needed.

Google says these AI models are best at coding Android apps

Google is testing various AI models for Android app development through a new platform called “Android Bench,” which evaluates the performance of leading AI language models (LLMs) against benchmarks specific to Android development. The benchmarks assess capabilities in areas such as Jetpack Compose, asynchronous programming, data persistence, dependency injection, navigation migrations, Gradle/build configurations, and interaction with Android components. Google has identified Gemini 3.1 Pro Preview as the top-performing model with a score of 72.4%, followed by Claude Opus 4.6 at 66.6% and OpenAI’s GPT 5.2 Codex at 62.5%. Gemini 2.5 Flash scored the lowest at 16.1%.

Replicate spatial data using AWS DMS and Amazon RDS for PostgreSQL

The process of migrating spatial data from self-managed PostgreSQL, Amazon RDS for PostgreSQL, or Amazon Aurora PostgreSQL-Compatible Edition to Amazon RDS for PostgreSQL or Amazon Aurora PostgreSQL-Compatible Edition using AWS Database Migration Service (AWS DMS) is outlined. Spatial data includes points, lines, polygons, and collections of these features, which are essential for applications like mapping and asset tracking. AWS DMS treats spatial columns as large objects (LOBs) and requires proper configuration for LOB handling and PostGIS support to avoid migration failures. PostGIS is an extension for PostgreSQL that manages geospatial data types and functions, enabling operations such as radius searches and distance calculations. Amazon RDS for PostgreSQL fully integrates with PostGIS, making it suitable for geospatial applications. The migration solution involves ensuring compatibility of PostGIS versions between source and target databases, configuring AWS DMS, and validating the migration. Prerequisites include having an AWS account, RDS instances for source and target, a DMS replication instance, and the PostGIS extension installed on both databases. Tables must have primary or unique key constraints, and geometry columns must be nullable for LOB handling. Best practices for configuring PostGIS include validating version compatibility, monitoring resource usage, and establishing backup strategies. Implementation steps involve creating a spatial table in the source database, preparing the target database, configuring the AWS DMS task with specific settings, and monitoring the migration process through CloudWatch logs. Common errors during replication may relate to LOB handling or PostGIS data types. Post-migration validation includes comparing row counts, verifying geometry data types, and ensuring the functionality of PostGIS spatial functions. Finally, it is recommended to clean up all resources post-migration to avoid ongoing charges.

How to migrate applications to Windows 11

Organizations are transitioning from Windows 10 to Windows 11 following the end-of-support date for Windows 10. Windows 11 is designed to support most applications that ran on Windows 10, but challenges may arise due to undocumented legacy applications and configurations. A thorough evaluation of devices, including installed applications and data locations, is essential to minimize disruptions during the upgrade. Migrations can be categorized as clean installations or in-place upgrades. A clean installation erases the previous OS and data, while an in-place upgrade retains existing settings and applications. In-place upgrades are not allowed for certain transitions, such as from Windows 10 Home to Windows 11 Pro without first upgrading to Windows 10 Pro. IT professionals often prefer clean installations to avoid carrying over issues from the previous OS. During an in-place upgrade, data in library folders is retained, but data in the Windows folder may be at risk. Compatibility issues may arise with poorly designed applications or drivers post-upgrade, particularly with legacy applications reliant on outdated frameworks. Preparation for migration includes creating an inventory of applications, identifying potential incompatibilities, and ensuring backups of data. IT must also confirm hardware meets Windows 11 requirements. If a clean installation is chosen, strategies for application installation must be developed, utilizing tools like System Center Configuration Manager or Microsoft Intune. Validation and testing of migration tools should occur in a lab environment, followed by a pilot deployment on a small percentage of machines. After successful pilot testing, the final deployment can proceed, followed by an audit to address any issues. Careful planning and testing are crucial for a smooth migration process.
