The blog post discusses how Dynatrace utilizes the Site Reliability Guardian to automate software delivery and quality validation, embodying DevOps and Site Reliability Engineering (SRE) best practices to ensure reliable, secure, and high-quality software releases. Announced at Perform 2023, the Site Reliability Guardian allows development teams to establish quality objectives in their code, which are validated throughout the delivery process, from development to production environments. It supports a shift-left approach, providing insights into production environments and enabling pre-production validations to improve software quality. Various Dynatrace teams leverage the Guardian for tasks such as monitoring demo applications and conducting chaos testing using AWS Fault Injection Simulator, ensuring the resilience and performance of applications. The Guardian also facilitates release validation through the "four golden signals" (latency, traffic, errors, and saturation) using Dynatrace Grail's capabilities. The post encourages organizations to adopt these practices early in the software development lifecycle and invites feedback on the Site Reliability Guardian through the Dynatrace Community.
