Streamline Amazon Aurora database operations at scale: Introducing the AWS Database Acceleration Toolkit

The AWS Database Acceleration Toolkit (DAT) is an open-source solution that enhances database performance, particularly for Amazon Aurora, by utilizing Terraform for setup, provisioning, and maintenance. DAT helps organizations reduce time to market, improve customer satisfaction, and optimize costs. It is beneficial for DevOps teams, SaaS providers, and enterprises transitioning from commercial databases to Aurora. One example of its effectiveness includes a customer reducing database migration time from 12 months to 4 weeks for over 100 databases, achieving zero outages over six months, increasing database team productivity by 60-70%, and lowering infrastructure costs by 42%. DAT's architecture includes automated resource provisioning and security through Terraform, with source code available in a Git repository. It offers multiple provisioning options for Aurora clusters, including the Terraform CLI and Jenkins pipelines. Key modules include: - Aurora cluster module for creating new clusters with customization options. - Amazon RDS Proxy for enhancing application performance and security. - Aurora GlobalDB for creating clusters across AWS Regions for disaster recovery. - Aurora Monitoring for configuring CloudWatch dashboards to monitor database performance. Use case examples are provided in the Git repository for both Aurora PostgreSQL-Compatible and Aurora MySQL-Compatible engines. Deployment options include using Terraform directly, setting up a new Jenkins instance, or integrating with an existing Jenkins setup. To provision an Aurora PostgreSQL cluster, users must clone the DAT repository, navigate to the appropriate folder, configure the Terraform variable definition file, initialize the working directory, execute a plan, and apply the changes. Security features include customer-managed keys, integration with AWS Secrets Manager for password management, and enhanced monitoring through CloudWatch. To clean up, users can destroy the Aurora cluster with a Terraform command.

Windows 10 is ending: How to install Windows 11 on an unsupported PC

Support for Windows 10 will officially conclude in October 2025, prompting users to seek alternative solutions for security and updates. Users with devices that do not meet Windows 11 requirements can install it on unsupported hardware using a tailored ISO and a tool called MicroWin. To create a personalized Windows 11 image, users must run a command in the Windows terminal to activate WinUtil, which allows downloading the latest official ISO from Microsoft. Users can customize their installation settings and generate a modified, lighter ISO. After creating the ISO, it can be transferred to a USB drive for installation. This method helps extend the lifespan of older PCs as users transition from Windows 10.

Migrate Google Cloud SQL for PostgreSQL to Amazon RDS and Amazon Aurora using pglogical

PostgreSQL is a popular open-source relational database used by enterprise developers and startups, enabling rapid prototyping and supporting mission-critical applications. Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL-Compatible Edition facilitate easy setup, operation, and scaling of PostgreSQL deployments in the AWS Cloud, automating administrative tasks like software installation, storage management, and backups. The pglogical extension, compatible with PostgreSQL versions 9.4 and higher, allows for asynchronous replication and is supported on RDS for PostgreSQL and Aurora PostgreSQL from version 12. It uses a publisher/subscriber model for logical streaming replication. To migrate a PostgreSQL database from Google Cloud SQL to RDS for PostgreSQL or Aurora PostgreSQL, users must configure the primary database in Cloud SQL, create a PostgreSQL user with replication privileges, enable logical replication parameters, and create the pglogical extension. The RDS instance also requires a special user for replication, enabling logical replication parameters and creating the pglogical extension. Known limitations of pglogical include the inability to replicate primary key changes directly, the need to manually transfer extensions, and the lack of support for materialized views and large objects. Workarounds involve using surrogate keys for primary keys, manually creating extensions, and converting large objects to bytea columns or storing them in Amazon S3. DDL statements are not automatically replicated, but can be queued using the pglogical.replicate_ddl_command function.

Do I need an antivirus and a VPN?

Reliance on antivirus software for device protection is common, but certain threats, especially ransomware, can bypass even the best solutions. Cybercriminals have shifted tactics from encrypting data for ransom to exfiltrating sensitive information and threatening to leak it. The availability of ransomware kits and the use of AI by attackers have made cybercrime more accessible and targeted. Remote work environments increase vulnerabilities, as hackers exploit unsecured networks and personal devices. Antivirus software can help protect against malware and viruses, but built-in solutions often lack comprehensive security. A high-quality antivirus program can enhance protection through advanced features and AI. A Virtual Private Network (VPN) encrypts data and secures internet traffic, making it a valuable tool for cybersecurity. Implementing a VPN is cost-effective compared to potential data breach costs. Using both a VPN and antivirus software is essential for comprehensive coverage, as they address different security aspects. Businesses may need advanced endpoint protection solutions for heightened security, which continuously scans for suspicious behavior and integrates multiple security features. Despite these tools, proper personal practices and cybersecurity awareness are crucial to minimize vulnerabilities and human error, which is a leading cause of cyberattacks.

Malwarebytes Premium Security review

Malwarebytes, founded in 2004 by Marcin Kleczynski, is an independent cybersecurity company that provides effective malware protection globally. The Malwarebytes Premium Security suite includes antivirus, phishing and identity protection, and an unlimited VPN powered by Mullvad. Pricing for the one-year license for a single device is .99, while a five-device license costs .99, and a two-year plan is priced at .98. The Premium Security Ultimate plan offers full identity protection and credit monitoring for .99 for the first year, with renewal at 9.99. A limited free version is available that detects and removes existing threats but lacks real-time protection. The app features a straightforward design with a clear dashboard, prioritizing user experience. Malwarebytes focuses on efficient scanning of commonly infected areas, completing test scans in 13 minutes. However, it does not automatically scan removable drives and lacks a warning system for password-protected files. Independent lab testing is infrequent, but Malwarebytes has received an AVLab 'Product of the Year' award and demonstrated strong performance in MRG Effitas assessments. In practical tests, Malwarebytes effectively detected known malware but struggled with behavioral detection against custom ransomware. It includes anti-phishing features, initially blocking 16% of phishing sites, which improved to 62% with the BrowserGuard extension. The unlimited VPN offers encryption and privacy but has limitations in unblocking streaming services. The identity protection feature scans for breaches associated with user email addresses and Social Security Numbers for U.S. users.
