.NET Rocks!Scaling a Monolith with Derek ComartinHow do you scale a monolith? Carl and Richard talk to Derek Comartin about his blog posts and YouTube series around scaling a monolith. Derek talks about the tendency for folks to want to split a monolith into microservices without assessing if it will make a difference. There is no one right way! The conversation digs into different approaches to scaling - up, out, using caching, queuing, and more! There are many approaches to scaling your applications, and yes, microservices are an option, but there are many others!This show is part of the Spreaker Prime Network, if...2023-07-0658 min

The Loosely Coupled ShowEvent Modeling with Adam DymitrukEvent Modeling is a method of describing systems using an example of how information has changed within them over time. Specifically this omits transient details and looks at what is durably stored and what the user sees at any particular point in time. These are the events on the timeline that form the description of the system.

Cloud Engineering Archives - Software Engineering DailyUsing CQRS to Make Controllers Lean with Derek Comartin
Command Query Responsibility Segregation (CQRS) is a powerful concept that has the potential to make for reliable and maintainable systems. It is also broadly misunderstood and means different things to different people.
Derek Comartin learned about the idea after viewing some talks by Greg Young and has since successfully applied the approach with great success and it has transformed the way he views features, business requirements, and dependencies. The result is a system that is easier to maintain and faster to enhance. Among his key lessons are that slices are better than layers, mediators improve dep...2017-03-1044 min
