I've been building microservices for several years. I've mostly used DotNet, DotNet Core, and Ruby on Rails to build them, and I've generally deployed them either into AWS EC2, or Azure Service Fabric. I've found most enterprises aren't ready for managing microservices in containers, either in the cloud or their own data centres. Keeping things … Continue reading Microservices with AWS Lambda

I've discussed the merits of JSON streaming in two prior posts: Large JSON Responses and Don’t Stream JSON Data, if you haven't read these yet then take a quick look first, they're not long reads. I'm attracted to the highly scalable proposition of scaling out the consumer, so many requests can be made individually rather than returning a … Continue reading Don’t Stream JSON Data (Part 2)

Streaming is a fantastic method of sending large amounts of data with only a small memory overhead on the server, but for JSON data … Continue reading Don’t Stream JSON Data

Building a cleaner view of the domain allows for some cleaner lines to be drawn between concerns, each with their own service. But inside … Continue reading Large JSON Responses
Sample code here. Recently I've been looking into Specification by Example, which people keep defining to me as BDD done the right way. Specification by Example fully implemented includes the idea of an executable specification. A concept that has led me back to FitNesse having given it the cold shoulder for the last six or seven years. … Continue reading Getting FitNesse to Work
The Domain Driven Design Europe happened in January this year in Brussels. Recently, two presentations were made available: Eric Evan's keynote speech is available here. Greg Young presents 'A Decade of DDD, CQRS and Event Sourcing' here. Both are worth a watch. I was particularly interested to hear some of Greg's opinions on what patterns … Continue reading DDD Europe 2016
