Udi Dahan on Service-Oriented Composition
Udi Dahan describes how we in a Service-Oriented Architecture (SOA) where client-side components for one service runs in the same process as components for other services can collect several logical calls into one larger physical call to avoid the high cost, in terms of client to server communication, that otherwise could be substantial.

Karma Refactors to Microservices
It's one thing to build a microservices application from scratch, quite another to refactor the architecture of a running application. Karma is doing exactly that and finding benefits and challenges of microservices architecture as they go.

Patterns for Building and Deploying Microservices
Managing micro-services means looking after lots of small systems talking to each other and automated provisioning as well as infrastructure automation is crucial, James Lewis states when sharing techniques and practices that have helped him manage the increased operational complexity a microservice architecture gives.

The Term µServices Already Defined Four Years Ago
“I coined the term µServices four years ago defining them as services that always communicate within the same process, without any overhead, as a way to separate these lightweight services from the heavy, costly, and complex services people tended to think about because of the advent of Service Oriented Architectures (SOA)” Peter Kriens recently claimed.

An Introduction to Microservices Design
Designing for simple components and systems is key when moving to microservices. The focus is on evolution of components and how we build systems that allow evolution and change, Russ Miles recently stated in an introduction to designing and building microservices.

Designing SOA Systems with ServiceMatrix
The Particular Service Platform has four headline components: ServiceMatrix, ServiceInsight, ServicePulse, and the well-respected NServiceBus. Over the next few weeks, we’ll be looking at each in turn starting with ServiceMatrix, their SOA design tool.

The Strengths and Weaknesses of Microservices
There has been significant buzz around microservices lately, enough to generate some hype. After implementing heavy and cumbersome SOA solutions for more than a decade, are microservices the solution the industry has been waiting for? Or, are microservices simpler than monolithic solutions?

A New Style Is Emerging in the Enterprise: Software-Defined Architecture
According to Gartner’s Yefim V. Natis, VP & Fellow, a new enterprise architectural style is rising these days: Software-Defined Architecture (SDA).

Microservices? What about Nanoservices?
Arnon Rotem-Gal-Oz has written an article following on from other discussions around the term Microservices and whether and how it relates to SOA. According to Arnon, this could be a slippery slope towards the Nonoservices anti-pattern, especially as some people define a Microservice in terms of lines of code.

Microservices: Usage Is More Important than Size
Using size for defining microservices is useless when determining a service responsibility, Jeppe Cramon states in a series of blog posts explaining his view on microservices and the coupling problems he finds in synchronous two-way communication.

Udi Dahan on Event-Driven Architecture and Loosely Coupled Systems
We should build systems more loosely coupled to achieve properties like robustness, resilience and scalability, Udi Dahan emphasizes in a recent presentation discussing how we can model our systems using more event-driven and asynchronous patterns and some of the challenges developers face when introducing these principles and patterns into development.

Microservices and SOA
Over the past year or so we've started to hear about Microservices as potentially new architectural style. Recently Thoughtworks' Martin Fowler and James Lewis wrote an article defining Microservices. However, Steve Jones takes issue with the general theme and much in that article, believing that there is little new here and this is just a Service Oriented Deliver approach.

Experiences from Enterprise Integration with REST
Large-scale legacy replacement is the hardest job in the IT industry and REST over HTTP is an attractive option for many of these projects. Architecturally REST has proven scalability and to fit in well with domain modelling, Brandon Byars, a principal consultant at Thoughtworks, claims when sharing his experiences from using RESTful integration in large scale legacy replacement projects.
