Delay of message sending into the future is a very powerful pattern and is often the preferable way of dealing with temporal problems compared to batch job that will run a query on the domain model and update some aggregates, Greg Young explained at the recent DDD Exchange conference in London.
High performance systems is about clean and representative models, the code doesn't have to be ugly, obscure and hard to read, Martin Thompson stated at the recent DDD Exchange conference in London.
We need to constantly challenge DDD to find the weak spots, Eric Evans stated in his keynote at DDD Exchange yesterday in London when walking through and challenging his own fundamental assumptions of Domain-Driven Design.
This article has been updated based on community and Jing Chen (Facebook)’s reaction. (See the Update section below.) Facebook came to the conclusion that MVC does not scale up for their needs and has decided to use a different pattern instead: Flux.
This article includes advice for doing enough up-front architectural design to provide the needed structure to start a project, aligning the team with the architect’s vision and assessing the possible risks.
InfoQ asked Kin Lane, the leading API evangelist, to share his views on open API designs and on what led him to launch the API Commons initiative with Steven Wilmott. He explains how translation and interoperability between the emerging API description languages matters, and how an open internet culture should prevent API Commons from making the same mistakes as past initiatives like UDDI.
Independently from each other, Richard Warburton in a presentation, and Mark Seemann in a blog post both talks about object-orientation and the SOLID design principles from a functional programming perspective.
The patterns & practices group at Microsoft have released a guide with solutions and patterns suitable when implementing cloud-hosted applications. The guide contains ten guidance topics together with 24 design patterns targeting eight categories of problems covering common areas in cloud application development. Also included are ten sample applications to demonstrate the usage these patterns.
After a long incubation period, Microsoft released its cloud-based integration tool called Windows Azure BizTalk Services. While reiterating their commitment to their on-premises integration tools, Microsoft has said that it will push innovation to its cloud platform first.
Russ Miles recently shared some thoughts and ideas about the needs for adaptability in a system and how his implementation of the Hexagonal Architecture can help in achieving this. He used a Java and Spring based application to exemplify how such a system can be implemented.
Andras Nemes, a web developer on the .NET platform, is doing a series of blog posts on the SOLID design principles and other design patterns he has found interesting in object-oriented programming and design, currently on D in SOLID, the Dependency Inversion Principle. Earlier he has among other patterns covered Command, Builder, Visitor, Bridge and Observer.
Use events for interactions between small business components to bring simplicity to a system’s architecture, Russ Miles suggests in a recent presentation about simple event-driven components, as a follow-up on his talk a month earlier where he laid the architectural ground for his ideas about simplicity.
Using events for interactions between small business components can bring simplicity to a system’s architecture, Russ Miles explained in a presentation last week talking about Architectural Simplicity through Events.
