In 2009 the Scrum Alliance registered a trademark application to register the term "Scrum User Group" as a protected trademark. Ken Schwaber, one of the original founders of the Scrum Alliance, has written a blog in which he objects strenuously to this move, and has asked for the community to respond to the move, with the possibility of filing an expensive legal challenge.
Google have released Kubernetes v1, a production-ready version of the open source container orchestration system. The Linux Foundation, in combination with multiple industry partners, have also announced the formation of the Cloud Native Computing Foundation (CNCF), which aims to advance the state-of-the-art for building cloud and container native applications.
Looking at Command Query Responsibility Segregation (CQRS) in a larger architectural context there are other architectural styles available. There are database technologies solving the same problems but in a simpler way, Udi Dahan states looking into ways of approaching CQRS. There is also a way that fulfils a lot of the CQRS goals but with fewer moving parts when CQRS is really needed.
REST and hypermedia has a lot of benefits but they significantly complicates building both the client and the server API, thus useful only in some scenarios Jimmy Bogard states in a series of blog posts highlighting what’s needed to get a full hypermedia solution from server to client including choosing a hypermedia-rich media type.
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.
