In this episode of the InfoQ podcast Charles Humble talks to Lucas Cavalcanti, a Principal Engineer at Nubank, which is the leading FinTech in Latin America and has become the most valuable digital bank in the world. They discuss Nubank’s early architectural choices including starting with Clojure and microservices, the challenges of using public cloud for financial services in Brazil, Nubank’s desire for immutable architecture and use of Alistair Cockburn's Hexagonal Architecture, and lessons learnt as the startup scaled.

Lucas Cavalcanti on Using Clojure, Microservices, Hexagonal Architecture and Public Cloud at Nubank

Charles Humble discusses Moldable Development with its creator Tudor Gîrba.  They discuss Gîrba’s key insight—that developers spend more than half their time reading systems rather than writing them—and how this lead to the creation of a novel development approach, Moldable Development, and a corresponding IDE, Glamorous Toolkit, which has the potential to change both how we reason and make decisions about software systems.

The InfoQ Podcast - 2022 InfoQ Software Architecture & Design Trends

Implementing microservices is really challenging, and there are many ways to fail. Holly Cummins has identified seven ways to fail at microservices, and on this episode of the podcast Thomas Betts asks her to describe them, and how they can be avoided.

Seven Ways to Fail at Microservices with Holly Cummins

Jonas Bonér, CTO of LightBend and creator Akka, discusses using Akka when developing distributed systems. He talks about the Actor Model, and how every Microservice needs to be viewed as a system to be successful. 

Why listen to this podcast:

 - Akka is JVM-based framework design for developing distributed systems leveraging the Actor Model - an approach for writing concurrent systems that treat actors as universal primitives and the most successful model with abstraction has been streaming
 - Circuit breakers in Akka are a backup and retry policy; they protect you by capturing failure data and allow you to roll back 
 - Every Microservice needs to be viewed as a system, it needs to have multiple parts that run on different machines in order to function and be fully resilient - thus is a Microsystem
 - Two different trends have emerged when it comes to hardware and environments: one is the trend toward Multi-core, the is a movement toward virtualized environments and the cloud
 - Saga pattern of managing long running transactions in a distributed system fits very well with messaging style architectures

Jonas Bonér on the Actor Model, Akka, Reactive Programming, Microservices and Distributed Systems

Rossen Stoyanchev talks to Wesley Reisz about blocking and non-blocking architectures, upcoming changes in Spring including Spring WebFlux, the reactive web stack in Spring framework 5, due this summer.  He also discusses the differences between rxJava and Reactor.

Why listen to this podcast:

 - Spring Framework 5 is due to be released June 25 2017
 - Spring Web Flux provides a web programming model designed for asynchronous APIs
 - Back-pressure is important in a server environment; less so within a UI environment
 - It’s possible to use a Spring Web Flux client within a Spring MVC applciation
 - Managing sets of thread pools is more complicated than having a scalable asynchronous system
