Last week, I had the opportunity to speak with J.C. Granger, host of The Future of BizTech Podcast (video here). We discussed the growing complexity of applications in the enterprise and how Glasnostic helps operators understand and control their behaviors. Below is the transcript, edited for clarity.

J.C.: Welcome everybody…

Earlier this month, I had the pleasure to talk with Matt Wolach on his “SaaS-Story in the Making” podcast (the videocast is here). Among other topics, we touched on the challenges of today’s cloud operations for architects, operations and security teams and how to make them resilient through real-time observability…

We’ve all been there. We’ve all gone down the rabbit hole, spending hours searching for that root cause, only to end up with a number of circumstances that contributed to our issue but no good way of doing something about it. …

From Applications to Services

Back in the day, an “application” was a well-structured, comprehensible affair. It was self-contained software deployed on target hardware to implement the desired functionality. That code was an “application” because it-quite literally-allowed the hardware to be to a real-world problem.

We’ve lived with this “application as application-of-hardware” model ever…

By more measures than one would like, 2020 was a transformative year. Whereas we may have entered it with the question, “How do we do Digital Transformation?” (and maybe “What is it in the first place?”), …

On the Glasnostic blog, we often talk about how the complex cloud-native environments we run today are prone to disruptive interaction patterns that can bring the business down. While this is certainly important to talk about, mere words do not do justice to the depth of the operational crisis we’re…

Building resilient systems and running them reliably is hard, especially in cloud-native environments, where everything is ephemeral and very few assumptions can be made over longer stretches of time.

It used to be easier. Applications used to be self-contained, two- or three-tier architectures that could be provisioned with infrastructure and…

With today’s increasingly complex and evolving cloud architectures, monitoring and observability attract significant attention but are at times still poorly understood. When should I rely on monitoring and when on observability? What should I monitor, and what should I “observe”? What even is the difference between monitoring and observability?
