How Firmex used AWS SCT and AWS DMS to move 65,000 on-premises Microsoft SQL Server databases to an Amazon Aurora PostgreSQL cluster

Firmex is a provider of Virtual Data Rooms, opening over 20,000 new rooms annually and focusing on security and availability for clients during due diligence processes. The company previously managed around 65,000 databases across four Microsoft SQL Servers but faced challenges related to database limits, backups, and licensing terms. In 2020, engineers recognized they were nearing the maximum database limit and shifted from a database-based isolation model to a schema-based isolation approach using PostgreSQL. This transition involved collaboration with AWS to utilize Aurora PostgreSQL-Compatible Edition, which offered better performance and cost-effectiveness. The migration process required extensive work, including converting stored procedures and addressing data migration challenges such as endpoint and task limits with AWS DMS. Firmex's engineers developed custom tooling to manage the migration effectively, ensuring minimal downtime for customers. Post-migration, they have seen improved performance and reduced operating costs, with ongoing efforts to optimize their PostgreSQL utilization further.

The Countdown to Windows 10 End of Life: What IT Teams Need to Know

Microsoft will discontinue support for Windows 10 on October 14, 2025. Extended Security Updates (ESUs) will be available for a maximum of three years at approximately per device. Windows 10 is currently the most targeted among older Windows operating systems, facing high-severity vulnerabilities. Organizations should conduct an asset audit, evaluate ESUs, migrate critical systems to the cloud, and establish a decommission plan for legacy systems. Morphisec offers a lightweight security solution for legacy systems, utilizing Automated Moving Target Defense (AMTD) technology to protect against advanced threats without the need for updates or internet connectivity.

The public preview of Windows Admin Center version 2410 is now available

Microsoft has released version 2410 of its Windows Admin Center app, which cannot be installed alongside version 2311 or earlier versions. Users with a high availability (HA) setup are advised not to install this preview version, as HA is not supported in the current backend implementation. Version 2410 includes enhancements to the virtual machine tool, allowing for quicker listing of virtual machines and a new toggle feature to switch between "detailed" and "light" modes. The update also addresses several bugs to improve user experience. General availability of the app is expected by the end of 2024.

Logical Replication in Postgres

Logical replication in PostgreSQL allows users to replicate data changes at a logical level, enabling the replication of specific tables or entire databases across different PostgreSQL instances. It requires two PostgreSQL instances and basic familiarity with SQL commands. To configure logical replication between two databases, db1 (primary) and db2 (subscriber), the following steps are taken: 1. **Preparing the Primary Database (db1)**: - Create a table: ```sql CREATE TABLE table1 (ad VARCHAR(15), soyad VARCHAR(15)); ``` - Insert initial data: ```sql INSERT INTO table1 (ad, soyad) VALUES ('Kemal', 'oz'); ``` - Create a publication for all tables: ```sql CREATE PUBLICATION alltables FOR ALL TABLES; ``` 2. **Preparing the Subscriber Database (db2)**: - Create the same table structure: ```sql CREATE TABLE table1 (ad VARCHAR(15), soyad VARCHAR(15)); ``` - Create a subscription: ```sql CREATE SUBSCRIPTION mysub1 CONNECTION 'host=localhost port=5432 user=postgres dbname=test9' PUBLICATION alltables; ``` 3. **Testing the Replication**: - Insert new data into db1: ```sql INSERT INTO table1 (ad, soyad) VALUES ('alı', 'oz'); ``` - Verify data in db2: ```sql SELECT * FROM table1; ``` - The expected output in db2 will show both the initial and new data: ``` ad | soyad -------+------- Kemal | oz alı | oz ```

PostgreSQL 17 delivers a leap forward for open-source databases

PostgreSQL 17 has been released by the PostgreSQL Global Development Group, featuring significant performance enhancements and new features for data management. Key improvements include a restructured memory management system for vacuum operations, optimized storage access, and better performance for high concurrency workloads, potentially doubling write throughput. The release introduces a new internal memory structure that reduces memory usage during vacuum processes by up to 20 times, leading to faster operations. For developers, PostgreSQL 17 enhances JSON capabilities with JSON_TABLE and includes SQL/JSON constructors. The COPY command for bulk loading and exporting data is now up to twice as fast, and logical replication has been improved to allow major version upgrades without dropping replication slots. Security features include a new TLS option for direct handshakes and the pg_maintain role for maintenance operations without superuser access. Backup capabilities have been expanded to support incremental backups, and monitoring features have been enhanced with new options for analyzing I/O operations and session wait events.
