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.

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.

Has one of the decision makers in your organization decided that you have to go "all in on technology X" because they saw a great presentation at a conference or got a great sales pitch from a vendor? If that is the case then this episode is for you and you should forward it to those decision makers.
Sebastian Vietz, Director of Reliability Engineering and Host of the Reliability Enablers Podcast, shares his thoughts on considerations when picking a technology like Serverless. We discuss the importance of knowing limits, best fit architectural patterns and things that should influence your technology decisions!
Being aware of coldstarts, a 20000 concurrent request limit or 512mb being an ideal size for Lambda are just some of the things we can all learn from Sebastian.

When thousands of systems show a blue screen - which ones do you fix first to quickly bring up your most critical systems? For that you need to know which systems are impacted, which mission critical applications run on it, and which depending systems are also impacted by something like the recent CrowdStrike incident!
We have invited Josh Wood, Principal Solutions Engineer at Dynatrace, who was one of the first responders helping organizations to leverage observability data to identify which systems to fix first to bring critical apps such as ATMs, Self-Service Terminals, POS (Point of Sales), ... back up again quickly.
In this special episode Josh is walking us through the technical details of the CrowdStrike BSOD (Blue Screen of Death), what caused it, how to leverage observability to get a priorities list of systems to fix first and what organizations can do to prevent software impacting issues in the future.

WebAssembly runs in every browser, provides secure and fast code execution from any language, runs across multiple platforms and has a very small binary footprint. It's adopted by several of the big web-based SaaS solutions we use on a daily basis.
But where did WebAssembly come from? What problems does it try to solve? Has it reached critical adoption? And how about observing code that gets executed in browsers, servers or embedded devices?
To answer all those questions we invited Matt Butcher, CEO at Fermyon, who explains the history, current implementation status, limitations and opportunities that WebAssembly provides.

"Because I don't want software to go down every single day in my next gig!" is what drives the motivation of Ash Patel, Reliability Advocate and Podcast host of SREpath, to talk about and educate IT professionals on the importance of building and operating reliable systems.
For 15 years Ash used to be Director of Operations at a private health service organization. He has experienced that patients couldn't get the treatment they expected due to unreliable software he was responsible for.
In our conversation Ash talks about how he had to close the knowledge gap on technology but also solve the problem by having engineers understand the pain and the requirements of their end users. One way to educate more engineers is through his podcast called SREpath where Observability has become a hot topic recently. Tune in, hear about the memorable stories from his guests from CapitalOne, IKEA and SquaredUp, and lets move towards a world where software is reliable by default.

Use Things you Understand! Learn the fundamentals to understand the layers of abstraction! And remember that we don't live in a world with unlimited resources!
These are advice from our recent conversation with Ernst Ambichl, Chief Product Architect at Dynatrace, who has started his performance career in the late 80s building the first load testing tools for databases which later became one of the most successful performance engineering tools in the market.
Tune in and learn about how Ernst has evolved from being a performance engineer to become an advocate for "Designing and Architecting for Performance". Ernst explains how important good upfront analysis of performance requirements and characteristics of the underlying infrastructure is, how to define baselines and constantly evaluate your changes against your goals.
On a personal note: I want to say THANK YOU Ernst for being one of my personal mentors over the past 20+ years. You inspired me with your passion about performance and building resilient systems -
SREs (Site Reliability Engineers) have varying roles across different organizations: From Codifying your Infrastructure, handling high priority incidents, automating resiliency, ensuring proper observability, defining SLOs or getting rid of alert fatigue. What an SRE team must not be is a SWAT team - or - as Dana Harrison, Staff SRE at Telus puts it: "You don't want to be the fire brigade along the DevOps Infinity Loop"
In his years of experience as an SRE Dana also used to run 1 week boot camps for developers to educate them on making apps observable, proper logging, resiliency architecture patterns, defining good SLIs & SLOs. He talked about the 3 things that are the foundation of a good SRE: understand the app, understand the current state and make sure you know when your systems are down before your customers tell you so!
