OpenObservability Talks Dotan Horovits

Time to explore the next frontier in cloud-native evolution: WebAssembly (WASM). Moving beyond containers and Kubernetes, WASM bears the promise to revolutionize the cloud landscape with unparalleled performance, portability, and security. Can it actually deliver on this promise? We discussed this and more it in this episode.

We delved into how WASM is transforming the way we build and run cloud-native applications, enabling a more efficient, scalable, and flexible infrastructure. We also got latest insights from the Cloud Native Computing Foundation’s work in the domain, the wasmCloud open source project and the tool landscape, along with the work of the WASM working group and standardization efforts with the Bytecode Alliance.

This episode’s guest is Taylor Thomas, Engineering Director working on WebAssembly platforms at Cosmonic. He serves as a co-chair for the CNCF’s WASM working group, and as a CNCF Ambassador. He actively participates in the open source community and is one of the creators of Krustlet and Bindle. His work at Intel, Nike, and Microsoft spanned various containers and Kubernetes platforms as well as WebAssembly platforms.

Redis is no longer open source. Just a few months ago, in March 2024, the project was relicensed, leaving its vast community confused. But the community did not give up, and started work to fork Redis to keep it open. 

In this episode, we delve into the Valkey project, a prominent fork of Redis, established under the Linux Foundation, which brought together important figures from the Redis community, as well as leading industry giants including AWS, Google Cloud, Oracle and others. Valkey has rapidly gained momentum and just reached General Availability (GA). 

Join us as we explore the motivations behind Valkey's creation, hear first-hand stories on its foundation and journey to GA, and learn of its Redis compatibility, roadmap and implications for the open-source community. 

Valkey's first Contributor Summit is taking place June 5-6 in Seattle and we will bring you announcements and updates hot off the summit. Our guest is Kyle Davis, the Senior Developer Advocate on the Valkey project, and a past contributor for Redis. 

Kyle currently works at AWS, a founding member of Valkey, and has a long history with open source and with forks. He was a founding contributor to the OpenSearch project, which started as a fork of Elasticsearch and Kibana after the latter's relicensing off OSS. Most recently Kyle worked to build a community around Bottlerocket OSS project.

In the past few years we’ve been witnessing tectonic shifts in the open source realm, with established projects taken off open source or otherwise turning to the dark side. On the other hand, we’ve seen active forks aiming to keep these projects open gaining momentum.

What does it mean for the Free and Open Source Software (FOSS) movement? Is this a trend or just a passing wave? What can we learn from it as vendors and as a community?

In this special episode concluding the fourth season of OpenObservability talks we will look back at the past year, including the very recent relicensing of Redis, and will discuss the state of open source with the help of open source pundit David Nalley.

David has been involved in open source for nearly two decades. He is the director of open source strategy at AWS and currently serves as the President of the Apache Software Foundation and serves on the Board of Directors for the Internet Security Research Group.

KubeCon Europe 2024 in Paris was the biggest event of the Cloud Native Computing Foundation (CNCF) to date, with over 12k participants. Have you missed it? We've got you covered! Join not one but two CNCF Ambassadors as they explore the latest and greatest highlights from the event that every tech enthusiast is talking about.  

But that's not all! We'll also zoom in on K8sgpt, a new entrant to the CNCF’s sandbox that uses generative AI to give Kubernetes superpowers to everyone. Does this open source project go beyond the GenAI hype and get us closer to diagnosing and triaging issues in plain English? Let’s ask the maintainers behind the project.

Our guest is Thomas Schuetz, a Principal Cloud Architect with a keen interest in cloud-native application delivery. Thomas teaches at an Austrian University of Applied Sciences, focusing on cloud-native technologies. Thomas is enthusiastic about open source projects, contributing as a Keptn GC Member and K8sGPT Maintainer, alongside his role as Co-Chair of the CNCF TAG App Delivery. He also brings a deep industry background from his past roles at Dynatrace and more.

OpenTelemetry is expanding beyond the traditional “three pillars of observability” and introduces a groundbreaking addition to its signals - Continuous Profiling. The new Profiling Special Interest Group (SIG) that was formed to lead the topic has already made significant advancements, to be featured at KubeCon Europe. Join us in this special panel episode of OpenObservability Talks as we explore the significance of this new dimension in understanding application behavior, optimizing performance, and gaining deeper insights into your systems. Our expert guests, Felix Geisendörfer and Ryan Perry, members of the OpenTelemetry Profiling SIG, share their insights into how Profiling enhances the OpenTelemetry framework, and update on the work for open specification and implementation. 

This special episode hosts a panel of two distinguished members of OpenTelemetry’s Profile SIG, and prominent members of the observability vendor ecosystem. Felix Geisendörfer is a Senior Staff Engineer at Datadog where he works on Continuous Profiling and contributes to the Go runtime. Before that he was working at Apple, co-founded Transloadit, contributed to node.js and inspired a generation of mad scientists to program flying robots with it. Ryan Perry is Principal Product Manager at Grafana Labs. He has built a career at various startups while actively contributing to open source projects and advancing open telemetry initiatives. Most recently he built Pyroscope, an open source continuous profiling project/company, which has been acquired by Grafana Labs.

The .NET programming language is taking cloud native deployment and observability seriously, and most notably with the recent announcement of .NET Aspire stack unveiled at the recent .NET Conf 2023. 

In this episode, we reviewed the open source maintainers’ journey to making .NET a "by default, out of the box observable platform", as ASP.NET Core creator David Fowler put it. David was this episode’s guest, and with him we dived into .NET Aspire and how it simplifies the complexities of cloud app development with capabilities around service discovery, observability, and resilience. We discussed the local developer experience, the path to developer observability, and what we can expect from the upcoming GA release of .NET8.

David Fowler has been at Microsoft for 15 years working on developer frameworks and tools in the .NET space. He's one of the creators of several popular OSS frameworks and tools such as NuGet, SignalR and ASP.NET Core, and also architected the Azure SignalR Service. Originally from Barbados, he's an avid open-source advocate and developer currently focused on simplifying developer experiences in the microservice space.
