Domain-Driven Design #06: aggregate and aggregate root

We observe that more and more customers are starting to use cloud computing. This is no longer a forbidden fruit, but it is becoming one of the key elements of modern IT infrastructure. Most companies have some combination of cloud and on-premise solutions. The number of applications from different vendors used in large corporations as well as smaller startups are growing rapidly. The second notable trend is the willingness to react quickly, change strategies and generate innovative ideas based on as muc...

Reading time ~7 minutes I will be back to the series about data modeling in noSQL databases, but for now, I want to note down a few arguments that are still hot after an interesting discussion with a friend. The talk boiled down to a simple question:Should I use a service mesh or use a bare bones Kubernetes? I know how strange the combination of bare-bones and Kubernetes sounds, but this is the world we are living in :). I’m standing firmly on the position that service mesh is the only way to go. Her...

Reading time ~6 minutes Querying hierarchical data is always where the big boys of SQL shined. And I really mean the big boys part since only Oracle, and Microsoft SQL Server have support for CTE (Common Table Expressions) that allow for executing one SQL statement what will fetch a subtree. There are data modeling approaches that allow for doing hierarchical data reads with noSQL databases and databases without support for CTE. The most common and obvious example of hierarchical data is the family tr...

We live in a world of dynamically changing technologies. New ways of architecturing our solutions, new frameworks and libraries seem to appear on almost daily basis. But good software engineering is not about fancy frameworks and solutions aggressively promoted by their vendors. It is not about doing something because Netflix or Google did it. It is about taking well-thought-out decisions based on facts and knowledge. That’s why it is important to be familiar basic architectural concepts like CQRS. It is...

Recently I've been involved in multiple discussions around Web Components and I noticed that there are questions that still introduce a lot of confusion among front-end developers.
