Free eBook/Guide on ‘.NET Microservices – Architecture for Containerized .NET Applications’

The microservices architecture is emerging as an important approach for distributed mission-critical applications. In a microservice-based architecture, the application is built on a collection of services that can be developed, tested, deployed, and versioned independently. In addition, enterprises are increasingly realizing cost savings, solving deployment problems, and improving DevOps and production operations by using containers….

Domain Events vs. Integration Events in Domain-Driven Design and microservices architectures

This blog post is about comparing several approaches of Domain Events vs. Integration Events patterns already published by the community. I might evolve this post depending on feedback and some implementations we’ll be doing in the short/medium term. So, feel free to discuss about it with comments at the end of this post. I’m open…

Scoping CQRS and Event-Sourcing Guidance Project

I am collaborating with the patterns & practices team. We are considering doing a guidance project on implementing systems using the Command & Query Responsibility Segregation (CQRS) approach. This is not going to be a framework or reusable components. We are positioning this project as a learning journey and envision providing an experience report that…

We completed the IASA-DDD Conference! (November 7th 2011)

It was a remarkable DDD (Domain Driven Design) event in Madrid, Spain. We got around 150 attendees!!, and taking into account that this is the inaugural event from the IASA-Spain association, and this association was almost unknown in Spain, until now, it is something I must highlight. Of course, having the keynotes delivered by Eric…

Value-Object pattern implementation in .NET

Regarding DDD patterns, here I link two nice Value-Object implementation samples: http://elegantcode.com/2009/06/07/generic-value-object/ http://grabbagoft.blogspot.com/2007/06/generic-value-object-equality.html

Implementing a Value-Object Base class (Supertype pattern–DDD patterns related)

It is usually a recommended practice to have Value-Object base-class so we can have common functionality which can be used by all of our value-object classes. Typically, comparison methods or any other common subject for Value-Objects, should be included here. Below I show a sample Value-Object Base-Class: public class ValueObject<TValueObject> : IEquatable<TValueObject>    where TValueObject :…

Don’t like EF 4.1 ‘Data Annotations’ for DDD Architectures implementation –’Fluent API’ fits better for that!

I write this post in order to get some feedback regarding what I currently think about EF 4.1 Data Annotations and how it fits in DDD Architectural styles. About DDD Architectural styles, here it is our Architecture Guide (Though we are actually writing its second edition, adding EF 4.1 Code-First approach). But most DDD Architectural…
