Migrating mission-critical payments at Nubank to Amazon Aurora PostgreSQL

Nubank, a digital banking platform with approximately 135 million customers in Brazil, Mexico, and Colombia, faced challenges with its payment infrastructure due to inefficiencies in managing 7.5 TB of self-hosted PostgreSQL databases. Queries took over 13 minutes to execute, and replication lags exceeded four minutes during peak times. To address these issues, Nubank evaluated database solutions based on developer productivity, operational efficiency, performance reliability, and scalability. They selected Amazon Aurora PostgreSQL-Compatible Edition for its compatibility, performance improvements, and automated features. The migration to Aurora was facilitated by AWS Database Migration Service (AWS DMS), which minimized downtime and allowed for efficient transition. Post-migration, query performance improved significantly, with some queries executing up to 1,900 times faster, and overall end-to-end service latency decreased, enhancing customer experience. The migration resulted in a 25 percent cost reduction and ensured compliance with regulatory requirements.

Google and Epic Abandon Settlement, Clearing the Way for Rival Android App Stores

Google and Epic Games have withdrawn their joint motion to modify a court injunction that requires Google to support third-party app stores within the Google Play ecosystem. A permanent injunction issued in October 2024 mandates Google to facilitate alternative app stores on Android devices, with support set to begin on July 22. Google plans to implement a ,000 annual access fee for these alternative marketplaces, while apps downloaded through these stores will still use the Google Play system for transactions. The agreement between Google and Epic includes provisions for reduced fees and alternative payment methods, separate from the injunction. The legal situation regarding third-party app stores does not directly affect Apple, but it may influence Apple's ongoing legal challenges with Epic Games and regulatory developments. Apple is currently appealing a ruling that requires it to allow link-outs and alternative payment options, with oral arguments expected in late 2026 or early 2027.

Google Play Opens the Door to Third-Party App Stores, Starting Next Week

Google will allow the installation of third-party applications directly from the Google Play Store starting July 22, following a court ruling in favor of Epic Games in a five-year antitrust lawsuit.

Google has launched a page for its Play Catalog Access Program, enabling third-party app stores to be featured on Google Play. Google's service fees will still apply, but app purchase commissions have been reduced from 30% to 10%. Developers can now offer alternative payment methods and distribute purchase links to their own websites.

After Google Vs Epic Games, Xbox Finally Gets Its Shot On Android

Google's grip over the Play Store was ruled as an illegal monopoly, leading to the opening up of Android to approved third-party app stores. This change allows developers to use their own payment systems and skip Google's cut in many cases, making it easier for other app stores to compete. This is significant news for Xbox, as it now has the opportunity to launch its own mobile game store on Android, which has been a goal for the company for years. The loosening of rules on Android provides Xbox with a chance to bring its mobile store to life and potentially increase revenue by selling games directly, running promotions, and offering better prices without Google taking a cut. The history of Xbox's fight against Google and Apple in the mobile app store market is also highlighted, with Xbox having faced obstacles in launching its mobile store features on Android in the past. With the recent changes, Xbox now has fewer roadblocks in its way and a real opportunity to establish a mobile storefront on Android.

Can Chromebooks Get Viruses? How to Protect Your Device

Chromebooks are designed with robust security features, including sandboxing, Verified Boot, automatic updates, data encryption, and Recovery Mode, which collectively reduce the risk of malware infections. However, they are still vulnerable to threats such as malicious Chrome extensions, scam Android apps from third-party stores, phishing attacks, and risks associated with using Developer Mode and cloud storage. Users can identify potential malware through signs like slow performance, unexpected pop-ups, and unusual battery drain. To remove malware, users should eliminate suspicious extensions, uninstall dubious apps, run antivirus scans, enable Google Play Protect, or perform a Powerwash to reset the device. To protect their Chromebooks, users should avoid Developer Mode, check app permissions, use two-factor authentication, verify website URLs, and use a VPN on public Wi-Fi.
