April 2020 Summaries

During a scheduled video conference with a Fortune 100 company, the author experienced technical difficulties due to improper Zoom permissions, highlighting the importance of preparing for online disasters, especially when working remotely. Drawing from personal experience at Amazon and Netflix, the author emphasizes the need for engineering teams to have a designated call leader, adequate hardware, and dedicated instant messaging channels to manage incidents effectively. The article suggests running online fire drills using Chaos Engineering to simulate failures, thereby identifying weaknesses and preparing teams for real outages. It also stresses the importance of maintaining conference call etiquette and ensuring that all team members have access to the necessary tools and software to respond swiftly to emergencies.

The Double Diamond Framework for Innovation, developed by the Design Council in the UK, is a versatile design process applicable across various fields, including software testing. It emphasizes divergent thinking to explore problems broadly before focusing on solutions, a method that can enhance traditional Quality Assurance (QA) practices. In the context of evolving software systems, particularly those utilizing microservices and cloud architectures, traditional QA methods may fall short in detecting systemic issues. The article suggests that Chaos Engineering, which intentionally introduces failures to observe system behavior, offers a more comprehensive approach. By simulating disruptions, Chaos Engineering provides insights into system resilience and functionality that traditional QA methods might overlook, thus enabling more robust and adaptable software systems.

Gremlin has launched a public beta for its agent on Windows, allowing Windows engineers to conduct chaos engineering tests like Shutdown, CPU, Disk, Memory, and IO exhaustion attacks on systems from Windows Server 2008 and Vista onwards. This expansion brings chaos engineering capabilities to Windows environments for the first time, enabling engineers to identify and rectify potential availability risks before they affect users. Gremlin offers a 30-day free trial of their automated reliability platform to help users uncover hidden system vulnerabilities. Additionally, the company has introduced features such as Custom Reliability Test Suites, Scoring, and Dashboards as part of its Reliability Management initiative, providing organizations with tools for consistent reliability testing and progress measurement.
