Increasingly, software developers have the ability to not only maintain and architect code, but extend their expertise to providing direction to the business. By using domain driven design, developers can discover customer behaviors and recommend practices that change the nature of the business.
WireMock v2, an API mocking and service virtualisation tool, has been released. Core enhancements include improved request verification failure reporting, the ability to create custom request matching logic (including the use of Java 8 lambdas), randomly distributed delays (currently with uniform and lognormal distributions), and matching on cookies and basic auth headers.
Amazon Web Services has launched their new Application Load Balancer, an OSI Layer 7 balancer that can route traffic to different end-points depending a set of URL rules.
We live in a distributed world, but that doesn’t mean we have to tackle every single problem that comes along with that. We only need to tackle those that really need to be solved; develop a sense of where value lies in your business and where it’s reasonable to take risks. This will make building distributed systems much easier, Camille Fournier claimed, when interviewed by Stefan Tilkov.
At QCon New York 2016, Etsy software engineer Stefanie Schirmer told how her company successfully transitioned to an API-first architecture that supports multiple devices, addresses server-side performance problems, and was quickly adopted by development teams.
On July 15th, Microsoft announced the Azure Premium Messaging service has reached General Availability (GA). Premium Messaging targets customers who would like more predictable messaging performance. InfoQ reached out to Dan Rosanova, Principal Program Manager on the Azure Service Bus team for additional insight into this milestone.
Although a monolith can be modeled in a respectable way, often they are turned into a big ball of mud. This is caused by multiple domain models becoming entangled within the monolith, and in Vaughn Vernon's experience this can happen within a few weeks or months, he claimed in a presentation at the Scala Days conference earlier this year.
Models play an important role in developing software for autonomous systems like self-driving cars; they are used to simulate and verify behavior, document the system, and generate code. Jonathan Sprinkle explains how to model software used in autonomous systems, the benefits of modeling, using test data to validate the software that drives a car and techniques for writing reliable code.
In a recent blog post, Uber engineer Emily Reinhold described how they broke a monolithic API into a modular, flexible microservice architecture. She highlighted a few key design and architectural choices that were key to Uber’s migration effort.
WSO2 MSF4J 2.0 has added support for Spring, Swagger definition generation, ExceptionMapper and StreamingOutput.
Akka.NET 1.1 was recently released, bringing new features and performance improvements. InfoQ reached out to Aaron Stannard, maintainer of Akka.net, to learn more about Akka.Streams and Akka.Cluster. Stannard also explains how the roadmap is planned with regards to the JVM implementation of Akka.
Microsoft has published their guidance for creating “RESTful” APIs. Roy Fielding calls them HTTP APIs that have little to do with REST.
Versioning of Web APIs by adding a version to the URI or using versioned media types does not work on the open web. What we rather need are contracts that evolve with the changes we need, Sebastien Lambla claimed in a recent presentation, describing ways of avoiding the need to version.
During the last DevNation Conference, Red Hat, IBM, Tomitribe, Payara, and the London Java Community announced the creation of the MicroProfile, a new initiative to try and leverage Java EE technologies to create a vendor-neutral microservices framework. The goal is to have a first public version by September 2016, allowing developers to create portable microservices in Java more easily.
At QCon New York, Eric Brewer described how advancing from continuous delivery to fast and stable continuous evolution requires a discrete construction step to define an immutable model of the system. Brewer’s compute infrastructure design team uses Helm to construct and safely validate new deployment models, prior to attempting real deployment, although the concepts are technology agnostic.
