Moving towards microservices means moving towards distributed systems where you have to deal with latency, authorization and authentication, and messages that do not arrive, argues Sander Hoogendoorn. With microservices you can break down large systems into smaller components to regain control over the architecture.
Almost five years in the making, Dropwizard's Java RESTful Web Service framework version 1.0.0 offers a host of new features including Java 8, Http/2 and Scala support, and the latest versions of supporting Java APIs.
One of the hardest problem when creating and developing microservices for an enterprise is their data. Analysing the business domain using Domain-Driven Design (DDD) and reason about what your data represents will help in achieving a microservices architecture, Christian Posta claims in one of a series of blog posts about microservices implementations.
Google has released gRPC 1.0, considering it stable and ready for production.
Spring Boot 1.4 and Dropwizard 1.0 were both released at the end of July, using fat JARs. As adoption of such frameworks and microservices increases, fat JARs are becoming a more common deployment mechanism. Earlier HubSpot cited issues where Fat JARs deployments experienced problems with the maven-shade-plugin, and efficiency problems when packaging 100,000 tiny files as a JAR.
IBM recently announced a cloud service for organizations looking to adopt blockchain technologies. The service is underpinned by the IBM LinuxONE platform which hosts a series of underlying services for blockchain processing. IBM is positioning this platform for organizations in regulated industries which require secure environments for testing and running blockchain projects.
In the webcast entitled "What's Better Than Microservices? Serverless Microservices," Alan Williams (Autodesk), Asha Chakrabarty (Amazon) and Alan Ho (Apigee) discuss the architecture of a serverless microservice built with lambda functions with Apigee end-points running on AWS.
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.
