Moving a Monolithic Application towards a Microservices Architecture
Migrating an existing system towards microservices is very different from building a new micoservices-based system, Joris Kuipers, architect at Trfork Amsterdam, claims in a presentation describing an ongoing process of refactoring a large monolithic application, based on CQRS using Axon framework, towards a microservices architecture.

Start with Events and DDD When Building Microservices
Domain-Driven Design (DDD) is a great technique bringing designs closer to the domains we are working in, but too often we make early decisions with a focus on structure, which is not the intention of DDD. Instead we should start with the events in a domain, Russ Miles claims when describing the advantages of going “events-first” when building microservices.

Is Gartner's Report of Java EE's Demise Greatly Exaggerated?
Gartner has produced a report called “Market Guide for Application Platforms”, citing Java EE’s “revenue decline” in reporting “a clear shift” in the application platform market. The Java EE community takes issue with those findings, in personal comments to InfoQ.

Netflix Conductor, an Orchestration Engine for Microservices
Netflix has developed an orchestration engine called “Conductor”, and has used it internally in production for the last year . During this time they executed some 2.6 million process workflows, starting with linear ones and ending with dynamic ones running over multiple days. Now they have open sourced Conductor, making it available to all those interested in workflow orchestration.

Focus on the Process, Not on Individual Microservices
The key to success when working with a microservices based distributed system is to focus on the distributed process as a whole, not on the microservices themselves. The services are the least important part, Eric Ess claimed at the recent Microservices Conference in London, in his presentation on how to monitor distributed processes at jet.com.

Azure Functions Reach General Availability
Microsoft recently announced an addition to its Platform as a Service (PaaS) offering called Azure Functions. Initially launched as a preview service in March 2016, Azure Functions provide developers with an event-driven serverless compute platform that allow organizations to pay for only what they consume.

Authentication Strategies in Microservices Systems
Software security is a complex problem, and is becoming even more complex using Microservices where each service has to deal with security, David Borsos explained at the recent Microservices Conference in London, during his presentation evaluating four end-user authentication options within a microservice based systems.

Large Scale Experimentation at Spotify
When you want to scale the number of A/B tests to do many experiments at the same time, you need to adopt your processes and platform, and it might also impact your culture. Doing product research with controlled experiments helps to confront your ideas about how customers will use your product in reality, and check if those ideas actually impact user behaviour.

Sharing Experiences from a Microservices Journey
In our continued effort to showcase lessons learned by microservices practitioners, we look at an article Piotr Gankiewicz has recently written with his own tips and tricks. These include references to CQRS, asynchronous architectures, service discovery and how choosing the right database for each service is important.

Technologies for the Future of Software Engineering
The Cloud, infrastructure as code, federated architectures with APIs, and anti-fragile systems: these are technologies for developing software systems that are rapidly coming into focus, claimed Mary Poppendieck. Systems are moving towards the cloud, and APIs are replacing central shared databases and enable the internet of things. We need to develop anti-fragile systems which embrace failure.
