Johannes Thönes talks to James Lewis, principal consultant at ThoughtWorks, about microservices. They discuss microservices’ recent popularity, architectural styles, deployment, size, technical decisions, and consumer-driven contracts. They also compare microservices to service-oriented architecture and wrap up the episode by talking about key figures in the microservice community and standing on the shoulders of giants.

In this episode of the ThoughtWorks Podcast, Neal Ford explains to Johannes Thönes what architectural considerations can be derived from the DevOps movement. 

This episode is a quick introduction to what Microservices are, what kind of architectural principles can be used to implement them, what a good test strategy for microservices can can look like. We also explain why you should have a continuous delivery practice running before starting to develop Microservices.  

DevOps and Microservices: Architectural Considerations

In the most recent Technology Radar, Scott Shaw and his colleagues from the ThoughtWorks Technology Advisory Board have added Microservice Envy to the Hold Ring, because they are concerned people are overdoing it. Start small, start with one Microservice,” is Scott's advice.

In this interview, Johannes Thönes talks to Scott about the prerequisites of being successful with a Microservice style architecture. First, you need to have an automatic deployment pipeline in place so you can deploy effectively and frequently to the cloud. You also need to have good DevOps practices and infrastructure automation around, so spinning up a dedicated server is not something that takes month.

Scott explains, that for being able to do Microservices, you need to have a clear understanding of the domain, which will give your Microservices their bounded context rooted in your domain. 

His advice for green field application, especially when you don’t have the practices in place, is to start with a monolith (or one lonely Microservices) and then split it up, when it makes sense. 

“Services need to evolve," he says.

[Recorded at the May 12, 2015 Microservices Meetup in NY.] Dealing with a traffic spike amounting to half of Amazon’s traffic each day when new sales are announced is no easy matter. Michael Bryzek, co-founder of retailer Gilt Groupe, talks about the architectural and cultural evolution that took place as Gilt introduced microservices during its growth over the course of the past seven years.

Transitioning from a few monolithic systems to somewhere in the range of 300 to 400 microservices today presented a lot of challenges along the way. First describing how they decided to prioritize which parts of their system to optimize by breaking it into smaller, more optimized services, Bryzek covers some of the challenges that were encountered and how they went about solving them. He also describes some of the steps they took right up until today, when they have begun transitioning to Amazon’s AWS.

Successfully building a microservices architecture typically takes a strong culture of trust with teams that are empowered to do the right thing. Bryzek discusses some of the sources of inspiration they had when faced with the problem of developing trust while growing their engineering capability, and some of the other organizations whose lessons they looked to for ideas.

In this episode, we talk about the role of a tech lead and how Pat Kua is helping new tech leads on their journey. We talk about the responsibilities of a tech lead and how this can be very overwhelming in the beginning. We also discuss the importance of a technical vision, what distinguishes a technical vision from an architecture and how we can teach tech visioning.

Every tech lead has his own style, so Pat tells me. So if you are new to the job, you will need to develop your own style. 

So, what should a participant in a tech lead program take out of it, I ask. Pat responds: “I would like to take the participants to say that they are comfortable [...] with the many responsibilities a tech lead has to deal with. I’m not expecting them to be experts in every skill.”

We close by talking about Pat’s Book “Talking with Tech Leads”, with interesting interviews from tech leads all over the industry.

Training Tech Leads

Functional programming has a lot of concepts which have to be yet discovered by mainstream programming. One, known especially from the Haskell programming language, are Lenses. 

Johannes Thönes met Chris Ford, Software Developer and ThoughtWorker from London, during XConf in Hamburg where he gave a talk on implementing Lenses in Clojure. In this 23 minute interview, Johannes talks with Chris about his experience with Lenses in Clojure. First they define what a Lense is and what you would want to do with it. Then they talk about the specifics of implementing Lenses in a programming language introducing the terms Functor and Function. We close the episode by talking about the possibility to implement lenses in other programming languages such as Java 8 or JavaScript.
