PurePerformance
The brutal truth about digital performance engineering and operations.Andreas (aka Andi) Grabner and Brian Wilson are veterans of the digital performance world. Combined they have seen too many applications not scaling and performing up to expectations. With more rapid deployment models made possible through continuous delivery and a mentality shift sparked by DevOps they feel it’s time to share their stories. In each episode, they and their guests discuss different topics concerning performance, ranging from common performance problems for specific technology platforms to best practices in development, testing, deploying and monitoring software performance and user experience. Be prepared to learn a lot about metrics.Andi & Brian both work at Dynatrace, where they get to witness more real world customer performance issues than they can TPS report at.

Why Security and Compliance must not be a showstopper for SaaS with Milan Steskal
Most services are moving to SaaS - whether it’s email, collaboration, customer relations, or finance. But not everyone can go to SaaS - or at least that’s the initial reaction when navigating certain industries’ rules and regulations.Milan Steskal - who worked in healthcare for many years - is now helping organizations ask the right questions and find the best solutions as they evaluate their options to move their observability data to SaaS. Tune in and learn about the questions to ask vendors and your internal security, privacy, and compliance teams. Milan also walks us through the capabilities SaaS vendors such as Dynatrace have put in place to protect data sent to the cloud so that it stays safe and only accessible to those needing access.Links discussed today:Milans LinkedIn Page: https://www.linkedin.com/in/milansteskal/Dynatrace Trust Center: https://www.dynatrace.com/company/trust-center/ Blogs on Trust: https://www.dynatrace.com/news/tag/trust-center/

Every Byte Counts: Web Performance Flashback with Andreas Taranetz
Andreas Taranetz is a software engineer and lecturer at the University of Vienna. He creates a lot of educational content around Web Performance Optimization. For the past seven years, he has also operated Wahlkabine, Austria's top website, for matching one's political views with the parties that are up for election.This episode was an amazing flashback - reminding us about the time when Steve Souders - the "godfather" of Web Performance Optimization - educated web developers about optimizing CSS, JavaScript, and server-side roundtrips.Tune in and learn why Web Performance is still such an important topic, how it relates to sustainability, why you should cache on every layer, and what the Static Site Paradox really is!

The Security and Resiliency Challenges of Cloud Native Authorization with Alex Olivier
Authentication (validating who you claim to be) and Authorization (enforcing what you are allowed to do) are critical in modern software development. While authentication seems to be a solved problem, modern software development faces many challenges with secure, fast, and resilient authorization mechanisms. To learn more about those challenges, we invited Alex Olivier, Co-Founder and CPO at Cerbos, an Open Source Scalable Authorization Solution. Alex shared insights on attribute-based vs. role-based access Control, the difference between stateful and stateless authorization implementations, why Broken Access Control is in the OWASP Top 10 Security Vulnerabilities, and how to observe the authorization solution for performance, security, and auditing purposes.Links we discussed during the episode:Alex's LinkedIn: https://www.linkedin.com/in/alexolivier/Cerbos on GitHub: https://github.com/cerbos/cerbosOWASP Broken Access Control: https://owasp.org/www-community/Broken_Access_Control
