At the Agile Testing Days 2015 Jose Lima from Redgate software shared his experiences with microservices. InfoQ interviewed him about advantages and disadvantages of developing products with microservices, how applying microservices has improved the quality of products, testing microservices and the skills that testers need, and his learnings from developing and testing microservices.
Moving from a monolith to microservices the only value business stakeholders care about is reducing cost. It will not increase or protect revenue and neither scaling nor distribution are good reasons that will convince the business, Ian Cooper claimed in his presentation at this year’s Microservices Conference in London describing guidelines moving from a monolith to a microservices architecture.
Microservices and SOA are often compared and contrasted, with some people suggesting they are unrelated whereas others believe they are close relatives. In a recent article Matt Braiser joins the debate on the side of the latter group and gives his reasons for believing that microservices owe their existence to the success of SOA principles.
The widespread adoption of Docker in infrastructure automation has led to a growing debate as to whether it supersedes configuration management. The consensus seems to be that both will co-exist in a complementary way.
Common misconceptions in large enterprises that Kim Clark meets are that microservices are fine grained WSDL operations or that APIs are microservices. A reason for this is that they are confusing interface granularity with component granularity, Clark claimed in a presentation at this year’s Microservices Conference in London.
InfoQ sat down with Markus Eisele, developer advocate at Red Hat, at the Devoxx BE conference, and asked about his thoughts on implementing microservice architectures within large-scale enterprise organisations. The conversation was primarily based on his recent O'Reilly mini-book publication, “Modern Java EE Design Patterns: Building Scalable Architecture for Sustainable Enterprise Development".
Caitie McCaffrey, distributed systems engineer at Twitter, talked about the benefits of stateful services which are less known than their stateless counterparts in the industry and how they can be scaled at the Strange Loop conference. The benefits include data locality and higher availability and stronger consistency models. McCaffrey also gave real world examples of stateful services.
Redux uses a unidirectional data flow similar to Flux, but it has a single store which is changed by cloning the original store and applying some functions without side effects. There is no Dispatcher.
Rising from the ashes of GigaOm the tribal gathering of cloud elders that is Structure has returned, and got off to a strong start with Battery Ventures' Adrian Cockcroft presenting on the State of the Cloud and Container Ecosystems. Cockcroft paid particular attention to the impact of containers, which wasn’t even a major discussion topic at the last Structure conference in 2013.
After several years of development, MBrace 1.0 was released last week. MBrace is a programming model for scalable cloud data scripting and programming with F# and C#. The project consists mainly of code libraries and cloud providers runtime.
Odile Moreau presented a case study of a big insurance company who started their Agile journey with Kanban for IT Hosting teams at the Lean Kanban Benelux 2015 conference. InfoQ interviewed her about the situation at the insurance company, what made them decide to choose Kanban, how teams use Kanban to manage flow and coordinate, and asked her to share learnings from this Kanban journey.
The second Microservices Conference arranged by Skills Matter is due early November with two days in Stockholm and London respectively. The list of speakers include the program lead for the conference Russ Miles, David A. Dawson, Björn Carlson, chief architect at Klarna, Viktor Klang, chief software architect at Typesafe, Ian Cooper and Daniel Bryant.
Storing events in a relational database and creating the event identity as a globally unique and sequentially increasing number is an important and maybe uncommon decision when working with an event-sourced Command Query Responsibility Segregation (CQRS) system Konrad Garus writes in three blog posts describing his experiences from a recent project building a system of relatively low scale.
JAX London 2015, which took place from 12th to 15th October at the Business Design Centre in London, United Kingdom, gathered many of the experts in the areas of Java, Microservices and other modern development practices. Although the topics were varied, the overall message seemed to indicate both that these technologies are maturing, and that users are learning to use them more effectively.
