Github Elasticsearch Interview

To best support continuously-delivering, autonomous teams, a software architect has to avoid being a blocker by trying to make all architectural decisions. In this episode of the podcast, Thomas Betts talks to Andrew Harmel-Law about how an advice process allows anyone to make an architectural decision, once they’ve had necessary conversations and properly documented their decision.

The Architecture Advice Process with Andrew Harmel-Law

So, after far too long a hiatus, we’re back on the Magpie Talkshow for a one-off episode where I interview Kafka creator and Confluent CEO Jay Kreps. 

I’ve been doing a small amount of work with Confluent recently, and through this I got the chance to meet Jay, and I thought he’d make a great guest for the show. So in this episode we’re going to learn about Jay’s own journey in the tech industry, as well as diving into the mindset behind Kafka and where you might want to use it.

There are a couple of firsts in this episode. Firstly, it was recorded remotely via video conferencing - I think the audio quality is pretty good, largely thanks to the use of zencaster. I did however have to do more editing than usual but I’m pretty happy with how it turned out. Secondly We’re also going to be sharing a video of our chat over on confluent's website, and I’ll update this post with a link once it’s available.

I do have to apologise for the sporadic nature of the episodes I’m putting out but as is often the case, life get’s in the way. In between our last episode and this one I setup my own company, and left australia for London, where I am currently based. I still plan to publish the occasional episode from time to time, so please do stay subscribed to the feed. Hopefully if things settle down a bit I may get back to a more regular posting schedule!

Jay and I talked about a number of things on the podcast, but the main one I wanted to highlight is previous guest Ben Stopford’s really interesting posts on using Kafka for sharing data between microservices. There are some fascinating ideas there which I think can solve problems many of us face when creating finer-grained distributed systems. You can find Ben's posts here: https://www.confluent.io/blog/author/ben/.

Anyway, I hope you enjoy the show!

Magpie Talkshow Episode 23 - Jay Kreps

In this podcast Shane Hastie, Lead Editor for Culture & Methods, spoke to Josh Evans, former engineering manager at Netflix on how Netflix does DevOps and the freedom and responsibility culture that undermines their way of working. 

Why listen to this podcast:

•	There are many interpretations of the term DevOps, it is a useful shorthand for a wide variety of technologies and approaches 
•	“You build it, you run it” is the concrete application of the freedom and responsibility culture
•	When building a platform tool make it so easy to use that the product teams are not tempted to try and build something for themselves
•	Product teams are free to experiment and learn, which can feel chaotic and is a valuable part of the freedom and responsibility culture
•	The value of blameless and safe incident reviews – the goal is to learn and find patterns and use that information to present whole classes of failure from happening in the future
•	Don’t view the value stream in a fragmented way – see the whole end to end system with all its interactions and dependencies and optimize the system as a cohesive whole rather than different tools and domains

Show Notes

Josh Evans on DevOps at Netflix

In this episode of the O’Reilly Programming Podcast, we revisit our June 2017 conversation with Sam Newman, presenter of the O’Reilly video course The Principles of Microservices and the online training course From Monolith to Microservices. He is also the author of the book Building Microservices: Designing Fine-Grained Systems.

In this episode of the O’Reilly Programming Podcast, I talk with Richard Warburton and Raoul-Gabriel Urma of Iteratr Learning. They are the presenters of a series of O’Reilly Learning Paths, including "Getting Started with Reactive Programming" and "Build Reactive Applications in Java 8." Warburton is the author of "Java 8 Lambdas," and Urma is the author of "Java 8 in Action."

On this podcast, we’re talking to Armon Dadgar, co-founder and CTO of HashiCorp. Alongside Mitchell Hashimoto, Armon founded HashiCorp over six years ago, and the company has gone from strength to strength, with their open source infrastructure product suite now consisting of Consul, Nomad, Vault and Terraform.

We discuss the formation of the HashiCorp research division, and explore some of the computer science research underpinning Consul and Nomad. We also cover the challenges of supporting teams when they are looking to embrace new modes of working with dynamic infrastructure, and Armon introduces the new learn.hashicorp.com educational website and accompanying community and support forums.

Why listen to this podcast:

- There is a lot of fundamental computer science research that underpins the HashiCorp infrastructure workflow and configuration tooling. This helps to ensure that these mission-critical tools perform as expected, and enables sound reasoning about scaling these technologies.
- The HashiCorp founders recognised the value of creating an industrial research-focused department within the company even when there were only 30 staff.
- The Consul service mesh and distributed key value store leverages consensus and gossip algorithms from computer science research, Raft and SWIM, respectively. The HashiCorp team contributed a novel research-based improvement to SWIM -- Lifeguard: SWIM-ing with Situational Awareness -- that was presented at the DSN academic conference
- Initially HashiCorp produced a new tool every 6-12 months, focusing on filling gaps within the infrastructure workflow tooling market. Now the focus is on refining the operator/user experience of the existing tools, creating more integrations with other platforms and tooling, and facilitating engineering teams adopting these tools, via the creation of educational resources and community forums.
- Standardisation within computing technology can offer many benefits, especially where interoperability is required or technology switching costs are high. Care must be taken to ensure the correct interfaces are created, and that the time is right to create appropriate abstractions.
- The HashiCorp team are focusing on "marching up the stack", with the goal that a lot of the underlying "plumbing" should be hidden from, or easily configurable by, application developers. This will allow developers to focus on adding value related to their business or organisation, rather than getting stuck with managing infrastructure.
