This is next post in series about real-time public transport tracking system development based on Azure infrastructure and services. Here we talk about data processing pipeline.…

Recently we had experience with Azure WebJobs hosting system and specificely - with disposable jobs. This blog post will describe how to properly handle disposable job dependency. Why Dependency? You might ask, why I need to have dependencies for the Azure WebJob. The only purpose for WebJob would be to kick-off rest of the services and transfer control to them to do the work. According to some software architectural theories - WebJob is just the delivery mechanism, it's a trigger for other services to step up and carry out the…

This part of the round shaped software blog posts as promised will be about mapping the theoretical terms and ideas mentioned in previous post to the actual code fragments and components. Application for the Post To move further and map theory to the code, I've created really simple sample application for managing the users. To demonstrate mediator internals and round shaped architecture - we will stick with hand crafted mediator. Mediator will be able to handle commands, queries and events. In the application you can: enlist existing users (for the…

This is the story how I discovered clean, understandable and maintainable software architecture. Why it's round shape and not pentagon, hexagon or any other *-gon shape? In this blog post I'll guide you through my journey. This part will cover theoretical side. Next blog post will map it to the code. Classical Architecture Agree that we all have been taught about N-tier/layer application software in high schools, universities or between the pages of some software development magazine?! Where order and most importantly dependency direction was stressed as one of…
