Reuse has been a watch word for almost everything that has happened in system development during the last thirty years, but reuse is like cyanide; in really small portions it can be healthy, using it too much it starts doing a lot of damage, Udi Dahan claimed in his presentation giving a different perspective on business logic at this year’s DDD Exchange conference in London.
Fred George talked about the Challenges in Implementing MicroServices and The Secret Assumption of Agile at the GOTO Amsterdam 2015 conference. InfoQ interviewed him about how make microservices as small as possible, challenges when implementing microservices and how to deal with them, why programming style matters, and what developers can do to develop their code writing skills.
The discussion on ITIL vs. DevOps is a common one. There are different views: ITIL and DevOps have different mindsets; ITIL and DevOps are compatible; they are different but both have their place in the IT department. Charles Betz, member of the Open Group IT4IT Forum, argues that their principles are at odds. ITIL is trapped in a phased workflow mindset. DevOps embraces lean product management.
An interview with Rob Howe, host of the MDSE session at the software engineering conference and CEO of Verum, about the state of practice and recent developments in model driven software engineering, the usage of this technology, whether he considers model driven software engineering to be a proven mature technology, and what the future will bring us in model driven software engineering.
At DockerCon 2015, Solomon Hykes announced that a broad coalition of vendors, users and industry leaders are coming together to form the Open Container Project (OCP) for the express purpose of defining common specifications around container format and runtime. The OCP will be run under the auspices of the Linux Foundation as a minimalist, non-profit, openly governed project.
InfoQ did an interview with Menno Vis, IT director of bol.com, about the benefits of increasing agility, how bol.com deploys Scrum, using roadmaps with agile, the challenges that have been faced when scaling agile, the main focus area's at bol.com for agile scaling, establishing loosely coupled teams, and the things that bol.com does for their people to have fun while doing their work.
When developing large complex systems and dealing with legacy code, organizations need to have systems in place to support integration and delivery. Modularization can help when agile is scaled with multiple teams that are working in parallel. It's not the framework or method that will do the job, but how your people will make it work to solve your problems says Hans Dekkers.
At QCon New York 2015, David Fullerton presented a deep-dive into the monolithic C# / MS SQL architecture that powers the Stack Overflow website, which handles over 4 billion requests per month. Fullerton argued that by focusing on performance, scalability was included ‘almost for free’; and that by minimising the number of external application services, the need to pay ‘SOA tax’ has been avoided.
The General Assembly of Ecma International has announced the approval of ECMA-262 6th edition, which is the Language Specification of ECMAScript 6 (ES6), also known as ECMAScript 2015.
There is tremendous value in microservices, probably giving us the best environment we have ever had for doing Domain-Driven Design (DDD), Eric Evans stated in his keynote at this year’s DDD Exchange conference in London. Iteration is the most important key to good design and microservices is the second attempt, after SOA, to get things right.
InfoQ interviewed Andrea Provaglio about business models for execution, optimization and discovery, dealing with uncertainty and leveraging it to create business value, understanding both value and cost, growing a discovery mindset, and creating a culture where people have the courage to make mistakes and can learn from them.
During the last months Martin Fowler among others have claimed that a microservices architecture should always start with a monolith, but Stefan Tilkov is convinced this is wrong, building a well-structured monolith with cleanly separated modules that later may be pulled apart into microservices is extremely hard, if not impossible in most cases.
Hans van Wezep, software architect at Philips Healthcare, talked about model-based migration at the Bits&Chips Software Engineering conference. InfoQ did an interview with van Wezep about the challenges in maintaining legacy software, why manual refactoring is error prone, using models to refactor and migrate a codebase, and the benefits of using models when maintaining legacy software.
Parse has announced its new Schema API, which allows to programmatically manipulate the database schema used by an app, and the Parse API Console, which aims to make it easier to use Parse REST API without writing any code.
InfoQ interviewed Jan van Moll about regulatory demands for software in healthcare, satisfying these demands with waterfall project or with a mix of waterfall and agile, and introducing agile in an R&D organization that needs to fulfill regulatory demands.
