In this episode of the InfoQ Podcast, Thomas Betts speaks with Chris Richardson about minimizing design-time coupling in a microservice architecture. Chris begins by defining design-time coupling, and contrasts it with runtime coupling. We then discuss some of the problems that arise from design-time coupling, anti-patterns and symptoms that are warning signs of high coupling, and the trade-offs that architects need to consider in their designs.

Chris Richardson on Design-Time Coupling in Microservices

Here’s what we know about open source: Developers are the new buyers. Community matters. And there will never be another Red Hat (i.e., a successful “open core” business model … nor do we necessarily think there should be).

Yet open source is real, and it’s here to stay. So how then do companies build a viable business model on top of open source? And not only make money, but become a huge business, like the IBMs, Microsofts, Oracles, and SAPs of the world? The answer, argues James Watters, has more to do with good software strategy and smart enterprise sales/procurement tactics (including design and a service-like experience) than with open source per se — from riding a huge trend or architectural shift, to being less transactional and more an extension of your customer’s team.

Watters, who is the SVP of Product at Pivotal (part of VMWare and therefore also Dell-EMC), is a veteran of monetizing open source — from OpenSolaris (at Sun Microsystems) to Springsource (acquired by VMWare) to Pivotal Cloud Foundry — with plenty of failures, and successes, along the way. He shares those lessons learned in this episode of the a16z Podcast with Sonal Chokshi and general partner Martin Casado (who was co-founder and CTO of Nicira, later part of VMWare before joining Andreessen Horowitz). These lessons matter, especially as open source has become more of a requirement — and how large enterprises bet on big new trends.

a16z Podcast: Monetizing Open Source (Or, All Enterprise Software)

In this podcast, QCon Chair Wesley Reisz talks to Julien Viet.  Viet is the project lead for Vert.x and a principal engineer at RedHat having taken over as project lead for Vert.x from Tim Fox in January 2016.  They talk about the newly released Vert.x 3.5.0, and the plans for Vert.x 4.0.

Why listen to this podcast:

* Vert.x adds RxJava2 support for streams and backpressure.
* Vert.x is a polyglot set of APIs, custom aligned for the specific language.
* It is unopinionated and can be used with any environments, since it doesn’t enforce a particular framework.
* Verticles communicate in-VM or through peer-to-peer networking for distributed applications.
* Vert.x 4.0 is on the roadmap for the future.

Show Notes

Julien Viet on the Newly Released Eclipse Vert.x 3.5.0 and Plans for Vert.x 4.0

Wes Reisz sits down and chats with Uncle Bob about The Clean Architecture, the origins of the Software Craftsperson Movement, Livable Code, and even ethics in software. Uncle Bob discusses his thoughts on how The Clean Architecture is affected by things like functional programming, services meshes, and microservices.

Why listen to this podcast:

* Michael Feathers wrote to Bob and said if you rearrange the order of the design principles, it spells SOLID.
* Software Craftsperson should be used when you talking about software craftsmanship in a gender-neutral way to steer clear of anything exclusionary.
* Clean Architecture is a way to develop software with low coupling and is independent of implementation details.
* Clean Architecture and Domain Driven Design (DDD) are compatible terms. You would find the ubiquitous language and bounded context of DDD at the innermost circles of a clean architecture.
* Services do not form an architecture. They form a deployment pattern that is a way of decoupling and therefore has no impact on the idea of clean architecture.
* There is room for “creature comforts” in a code base that makes for more livable, convenient code.
* “We have no ethics that are defined [in software].” If we don’t find a way to police it ourselves, governments will. We have to come up with a code of ethics.
