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.

Bernd Rücker, who has contributed to multiple open source workflow management projects, discusses orchestrating microservices with workflow management.  As distributed systems evolve into a family of microservices that must handle long-running stateful processes with time-dependent actions, events, multiple paths through the system, and complex rollbacks, the workflow management model provides a way to ensure clear modeling, correctness, and separation of concerns.   Rücker recommends a federated model in which each microservice is paired with its own workflow to handle retries and other policies and failure modes around that service.  Robert Blumen spoke with Rücker about microservice architecture, event-driven systems, long-running stateful processes versus synchronous request/response, event handling, time-outs, and handling exceptional conditions with compensating transactions. Rücker compares the choreography versus orchestration models for collaboration and discusses why orchestration provides a better separation of concerns.  The discussion delves into the implementation of workflow management systems including persistence, scaling, event handling, timers and scheduling, and similarities to CQRS.  The discussion wraps up with monitoring and visualization.

Vaughn Vernon, author of the book “Strategic Monoliths and Microservices” discusses his book with host Akshay Manchale about strategies for purposeful architecture from the perspective of both business decision makers and technical leaders.

Where do we go from here? How much impact will microservices have in the future?

The discussion of basic differences and similarities between microservices and SOA continues.

The Ivory Tower and the Street: Two views of Microservices.

The panel discusses basic differences and similarities between microservices and service-oriented architecture.

Microservices are hot, but is it the right approach for your project? A experts Chris Richardson, Adam Bien, Reza Rahman, and Karthik Gaekwad share insight on what goes into a successful microservices project in the real world.

Are Microservices and APIs Becoming SOA 2.0? Are monolithic applications an anti-pattern? Experts Chris Richardson, Luis Weir, Phil Wilkins, and Boris Scholl address these and other questions in this roundtable discussion.

Are you familiar with Project Helidon? It’s an open source Java microservices framework introduced by Oracle in September of 2018.  As Helidon project lead Dmitry Kornilov explains in his article Helidon Takes Flight, "It’s possible to build microservices using Java EE, but it’s better to have a framework designed from the ground up for building microservices." In this program we’ll dig into Project Helidon with a panel that consists of two people who are actively engaged in the project, and two community leaders who have used Helidon in development projects, and have also organized Helidon-focused Meet-Ups.

In this episode Jim Grisanzio talks with Dmitry Alexandrov about his session at Jfokus 2021. Dmitry is a well known speaker at Java conferences globally, and at this month's Jfokus he ran a live coding session on Project Helidon, which is a collection of Java libraries for writing microservices. Dmitry covered the performance improvements and new features in Helidon 2.1. See his session abstract here.

But Helidon is not just a Java engineering project for writing microservices. It's also an Open Source project. So developers can contribute globally via the community on GitHub. This is the real power of the technology -- the people sharing their experience and contributing to the project. And this is where Dmitry really gets emotional when he talks about Helidon. As a software developer, he loves the technology, but there's something special about his tone when he talks about the people he meets in the community.

Dmitry has been a Java Champion for several years now, and he recently jointed Oracle in Bulgaria. Get him on Twitter @bercut2000. Jim Grisanzio is a Sr. Community Manager in Oracle Developer Relations. Get him on Twitter @jimgris. Video from the interview is on YouTube.
