The Simple Notification Service, or SNS for short, is one of the central services to build serverless architectures in the AWS cloud. SNS itself is a serverless messaging service that can distribute massive numbers of messages to different recipients.

In December, information security researchers discovered a serious vulnerability in the popular open-source logging library, Log4j. If exploited, this vulnerability, known as Log4Shell, could allow malicious attackers to execute code remotely on any targeted computer. Millions of computers use Log4j.

If there is one thing that the pandemic has given us apart from a “new normal,” it's the massive spike in ransomware attacks across the globe. Despite law enforcement agencies telling victims to avoid paying ransoms, the average amount of rin 2021 exceeded a whopping $102 million per month.

In this episode of Mooving to… Stability: The Role of Catastrophic Failure in Software Design, we had the opportunity to chat with Jeff Atwood, yes that Jeff Atwood of, Coding Horror, Stack Overflow, and Discourse (Chief Happiness Officer). Jeff started writing 911 software in Boulder, Colorado for a small company, which was a crash-course in writing code for software that has real consequences. With this unique and deep perspective, B.J.

With the introduction of Cloud computing services, let it be the Family photo sharing feature on iPhone or documents on Google Drive, sharing and keeping up-to-date information became easier than ever before.
