With over 1,000 companies using it and 21.5K+ stars on GitHub, the Backstage open source project is quickly becoming a go-to tool for managing developer infrastructure. In this episode, I’ll sit down with Lee Mills, a Senior Engineering Manager from Spotify's Backstage project, to learn more about how the open source platform is revolutionizing the developer experience and how it aligns with the growing Internal Developer Platform (IDP) space. We’ll discuss the need that drove Spotify to build this internal tool, about the decision and journey to open source it and donate it to the CNCF (Cloud Native Computing Foundation). We’ll also discuss the new commercial plugins, what’s coming up on the roadmap, and much more. 

Lee has worked as an engineering manager for the past 12 years, from Amazon to Spotify and everything in between. Prior to that Lee had a mixed background working in academia as a lecturer, worked as a Boom Op for television in the UK and lived in more places than he can count.

The Cloud Native Computing Foundation (CNCF) is the home of the most prominent open source projects used today, such as Kubernetes, Prometheus, ArgoCD, Linkerd and more. These projects fuel today’s cloud native architectures and software release pipelines. With its immense growth, it has become difficult to keep tabs on the hundreds of new and evolving projects and specifications, the different working groups and technical advisory groups, the different community forums and events, and to see where it’s all heading.

I invited Chris Aniszczyk, CTO of the CNCF, to join me on this episode, to help us understand the CNCF landscape and evolution. We will also discuss the trends in observability and in the open source realm in general. Chris also has some interesting predictions to share. 

Chris Aniszczyk is an open source executive and engineer with a passion for building a better world through open collaboration. He's currently a CTO at the Linux Foundation focused on developer relations and running the Open Container Initiative (OCI) / Cloud Native Computing Foundation (CNCF). Furthermore, he's a partner at Capital Factory where he focuses on mentoring, advising and investing in open source and infrastructure focused startups.

At Twitter, he created their open source program and led their open source efforts. For many years he served on the Eclipse Foundation's Board of Directors representing the committer community and the Java Community Process (JCP) Executive Committee. In a previous life, he bootstrapped a consulting company, made many mistakes, lead and hacked on many eclipse.org and Linux related projects.

Many organizations struggle in understanding and monitoring the costs of their Kubernetes workloads, cloud infrastructure and cloud native applications. Moreover, different cloud providers use different conventions, which makes it difficult to compare across vendors and to monitor cost in multi-cloud environments. The lack of cost observability and vendor-agnostic FinOps standardization can become a critical business challenge.  

OpenCost is a vendor-neutral open source project for measuring and allocating infrastructure and container costs. It’s built for Kubernetes cost monitoring to power real-time cost monitoring, showback, and chargeback, across on-premises Kubernetes as well as cloud managed offering.  

I discussed this topic with Matt Ray, Senior Community Manager for the OpenCost project. Matt  has been active in Open Source and DevOps communities for over two decades and has spoken at and helped organize many conferences and meetups. He is currently the Senior Community Manager at Kubecost for the CNCF Sandbox Project OpenCost. Matt also co-hosts the Software Defined Talk podcast.

A 3-node Kubernetes cluster with Prometheus will ship around 40k active series by default! Do we really need all that data? The current state of Kubernetes open source monitoring is in need of improvement. High churn rate of pod metrics, proliferation of metrics with low usage, and configuration complexity are some of the issues that need to be addressed.

I discussed this topic with Aliaksandr Valialkin, CTO at VictoriaMetrics and creator of the open source project. We discussed the common problems, as well as directions and best practices to overcome some of these complexities as individuals and as a community. We also discussed VictoriaMetrics open source project and how it addresses some of these challenges.

Aliaksandr a Golang engineer, who likes writing simple and performant code and creating easy-to-use programs. Sometimes these hard-to-match requirements work together, like in the VictoriaMetrics case.

In this episode, hosted by Jonah Kowall we are excited to introduce Pranay Prateek the co-founder and creator of SigNoz to the audience. He is an entrepreneur who has been building an interesting and exciting open-source observability platform. The goal is a unified interface and data storage system which is scalable and manageable much more easily than today’s disjointed open-source tools. SigNoz has a goal of unifying tracing, metrics, and logging in a single platform and interface. We’ll dig into the evolution of this unique project from its creation until today, along with the adoption of the technology and contribution from the community. We will discuss the data architecture and their move from Druid towards ClickHouse, which is always a fascinating topic. Finally, we’ll elaborate on the future of SigNoz and where things are going with the project. Join me, Jonah Kowall, as I speak with Pranay Prateek on this episode of OpenObservability Talks.

Socials:

We all collect logs, metrics and perhaps traces and other data types, in support of our observability. But this can get expensive pretty quickly, especially in microservices based systems, in what is commonly known as “the cardinality problem”.  

On this episode of OpenObservability Talks I’ll host Ben Sigelman, co-founder and the GM of Lightstep, to discuss this data problem and how to overcome it. Ben architected Google’s own planet-scale metrics and distributed tracing systems (still in production today), and went on to co-create the open-source OpenTracing and OpenTelemetry projects, both part of the CNCF.

OpenTelemetry is one of the most fascinating and ambitious open source projects of this era. It’s currently the second most active project in the CNCF (the Cloud Native Computing Foundation), with only Kubernetes being more active. The entire industry is aligning behind this project, including incumbent monitoring vendors that were deeply vested in proprietary and closed-source agents to that end.

In this episode of OpenObservability Talks I’ll host Alolita Sharma to discuss OpenTelemetry, its origins and mission statement, as well as updates hot off the press from the recent KubeCon conference in Valencia about releases and future plans.

Alolita is co-chair of the CNCF Technical Advisory Group for Observability, member of the OpenTelemetry Governance Committee and a board director of the Unicode Consortium. She has served on the boards of the OSI and SFLC.in. Alolita has led engineering teams at Wikipedia, Twitter, PayPal, IBM and AWS. Two decades of doing open source continue to inspire her.

Developers hate monitoring, but we need it. We need it in many points of the software development lifecycle: before deprecating an API, before launching a new feature, after launching the feature, and more. In fact, monitoring needs can vary much more than the classic Ops monitoring.

In this episode I’ll host Liran Haimovitch to discuss how to determine what developers should be monitoring, the difference between observability for Dev and for Ops, and how observability fits into our current dev tools, dev stack and dev processes.

Liran is the Co-Founder and CTO of Rookout. He’s an Observability and Instrumentation expert with a deep understanding of Java, Python, Node, and C++. Liran has broad experience in cybersecurity and compliance from his past roles. When not coding, you can find Liran hosting his podcast, speaking at conferences, writing about his tech adventures, and trying out the local cuisine when traveling.

OpenSearch is a community-driven, open-source search and analytics suite derived from Apache 2.0 licensed Elasticsearch 7.10.2 & Kibana 7.10.2. The OpenSearch project started just over a year ago and is now the open-source alternative to ELK, which is no longer open source. The team has spent much of the last year getting the project going, but there was innovation as well. We will cover and discuss what OpenSearch has accomplished, but more importantly what’s coming next, including a big 2.0 release. We are joined in this episode by Eli Fisher, who is the product lead at AWS, working on the OpenSearch project. He’ll dive into recent launches, including several observability features, and innovations planned for 2.0 and beyond.

Google’s SRE Book popularized the concept of Service Level Objective (SLO) and the SLO-driven approach. But what does it really mean to make SLO driven decisions? How can we generate observability and synchronize teams around joint SLOs? And how can we automate SLOs and integrate them into the software release pipeline?

In this episode I’ll host Andreas Grabner. We’ll discuss the SRE practices, and how to automate SLO from dev all the way to prod. We’ll talk about the open source efforts to standardize the process under the Continuous Delivery Foundation, and about Keptn, the new CNCF open source project that promises to help with this automation.

Andreas Grabner (@grabnerandi) has 20+ years of experience as a software developer, tester and architect and is an advocate for high-performing cloud scale applications. He is a contributor and DevRel for the CNCF open source project keptn (www.keptn.sh).
