Preparing for Windows 11: Transitioning from planning to implementation

The end of support for Windows 10 is set for October 14, 2025, prompting businesses to ensure device readiness for Windows 11 to avoid financial and operational issues. Organizations relying on PCs must address hardware compatibility immediately to prevent compatibility problems, unplanned downtime, and budget strains. Windows 11 includes advanced security features and AI capabilities but requires devices with greater processing power and battery life. Older devices may not fully utilize Windows 11's features due to hardware limitations. Risks of not upgrading include loss of Microsoft support for Windows 10 devices, vulnerability to cybersecurity threats, and potential issues with new features and applications. Extended security updates are available for a maximum of three years at increasing costs. Practical steps for migration include evaluating device readiness, planning upgrades, securing data, testing applications, and training employees. Transitioning to Windows 11 offers an opportunity to modernize technology and improve efficiency.

The END of Support: Preparing for Windows 10 Transition » CBIA

Microsoft will end support for Windows 10 and Windows Server 2019 on October 14, 2025. After this date, Microsoft will no longer provide updates, including security patches and programming fixes, potentially increasing vulnerability to operational failures and cyber threats. Upgrading to Windows 11 may be possible at no additional cost if hardware meets minimum requirements. Companies should consider a migration strategy that balances costs and needs, possibly redistributing older devices for less demanding roles. For server upgrades, it is recommended to consolidate functionalities, utilize physical servers for virtual systems, assess company growth for informed investments, and prioritize redundancy through frequent backups.

Achieve up to 1.7 times higher write throughput and 1.38 times better price performance with Amazon Aurora PostgreSQL on AWS Graviton4-based R8g instances

Upgrading to Graviton4-based R8g instances with Aurora PostgreSQL-Compatible 17.4 in an Aurora I/O-Optimized cluster configuration results in significant performance improvements. The new instances provide up to 1.7 times higher write throughput, 1.38 times better price-performance, and reduce commit latency by up to 46% on r8g.16xlarge instances and 38% on r8g.2xlarge instances compared to Graviton2-based R6g instances. The Amazon Aurora PostgreSQL-Compatible Edition now supports AWS Graviton4-based R8g instances and PostgreSQL 17.4, which introduces performance enhancements for I/O-Optimized configurations, optimizing write operations and batch processing. R8g instances offer up to 192 vCPUs and 1.5 TB of memory, supporting larger configurations and providing up to 50 Gbps of network bandwidth. PostgreSQL 17 includes vacuum improvements, eliminates the need to drop logical replication slots during upgrades, and expands SQL/JSON standards. Aurora PostgreSQL-Compatible separates compute from storage, enabling independent scaling and maintaining six-way replication for durability, while processing changes as log records to reduce I/O operations. Performance benchmarks using HammerDB show improvements in throughput and commit latency across various workloads. For small workloads on 2xlarge instance size, throughput increased by 50.25% and commit latency improved by 33.87%. For medium workloads on 16xlarge instance size, throughput increased by 30% and commit latency improved by 17.44%. The most significant performance benefits arise from combining hardware upgrades from Graviton2 to Graviton4 with database engine upgrades from PostgreSQL 15.10 to 17.4. For small workloads, throughput increased by 70% and commit latency improved by 38.71%. For medium workloads, throughput increased by 70% and commit latency improved by 46.67%. Cost efficiency is also enhanced, with a 38% improvement in price performance and a 61.26% improvement in price-performance ratio when comparing Graviton2 and Graviton4 instances. Reserved Instances for Graviton4-based R8g instances offer additional cost-optimization opportunities.

Best practices to handle AWS DMS tasks during PostgreSQL upgrades

The AWS Database Migration Service (AWS DMS) provides a managed solution for migrating and replicating databases to AWS, supporting both homogeneous and heterogeneous migrations. It allows seamless data migration from PostgreSQL databases to any supported target and vice versa. Open-source PostgreSQL regularly releases new versions, and Amazon RDS aims to support these within five months. Upgrading PostgreSQL instances is essential for security and compliance. Minor version upgrades focus on security and bug fixes without adding new functionalities, while major upgrades can change system tables and data formats. AWS DMS tasks require careful management during PostgreSQL upgrades. For minor upgrades, ongoing DMS tasks should be stopped and then resumed post-upgrade. For major upgrades, replication slots must be dropped before the upgrade, which will invalidate ongoing DMS tasks. After the upgrade, a new CDC-only task should be created to resume data migration. Minor version upgrades of the target PostgreSQL database do not affect AWS DMS CDC tasks, but major upgrades require stopping the DMS task, performing the upgrade, and ensuring compatibility with the replication instance before resuming the task.

Upgrade strategies for Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL 12

Standard support for Amazon Aurora PostgreSQL-Compatible Edition and Amazon RDS for PostgreSQL version 12 will end on February 28, 2025. The final update for PostgreSQL 12, version 12.22, was released on November 21, 2024. PostgreSQL follows an annual major version release cycle, supporting each version for five years post-release. Upgrading to newer major versions requires careful planning and testing to ensure application compatibility. New features in higher PostgreSQL versions include performance improvements, enhanced security, and new functionalities. Aurora PostgreSQL now supports AWS Graviton4 instances, which provide up to 40% performance improvement over Graviton3 instances. Recommended upgrades include moving to PostgreSQL 16 or newer, with options for in-place upgrades, blue/green deployments, and out-of-place upgrades. Amazon RDS Extended Support allows continued operation on a major version beyond the standard support end date, available at an additional cost. Extended Support for Aurora PostgreSQL 12.x and Amazon RDS for PostgreSQL 12.x will incur charges starting March 1, 2025, and will cease upon upgrading.

Microsoft stopped nagging some Windows 10 users with full-screen Windows 11 ads

Microsoft plans to broaden Windows 11 upgrades for eligible Windows 10 users as support for Windows 10 nears its end. Initially, the strategy involved displaying full-screen ads to promote the upgrade, which faced significant backlash. In response, Microsoft announced it would stop these intrusive ads on eligible Windows 10 devices with the April 2024 security update. However, a specific timeline for the Windows 11 upgrade for non-managed domain-joined devices is still unclear. Regular users may still encounter prominent Windows 11 advertisements when restarting their machines.
