Focus on Service Capabilities, not Entities

One of the most common pitfalls I think I’ve fallen into is focusing too much on data entities rather than service capabilities. What tends to happen is building up a domain model of behaviors related to single entities. As I’ve mentioned in my post about using language to find service boundaries, you can have the same entity that lives in a different context, but that owns specific behaviors and data. This blog post is in a series.

Autonomous Services

In my previous post, I explored how words and language used by users of our system in our domain space can have different meaning based on their context. This establishes which services own which behavior and data. In this post, I’m going to explore why services are autonomous and how we can communicate between them This blog post is in a series.

Roundup #45: AWS Secrets Manager, Microservices, ASP.NET Core Architect, WCF vs gRPC

Here are the things that caught my eye this week in .NET.  I’d love to hear what you found most interesting this week.  Let me know in the comments or on Twitter. AWS Secrets Manager client-side caching in .NET AWS Secrets Manager now has a client-side caching library for.NET that makes it easier to access secrets from .NET applications. This is in addition to client-side caching libraries for Java, JDBC, Python, and Go. These libraries help you improve availability, reduce latency, and reduce the cost of retrieving your secrets. Secrets Manager cache library does this by serving secrets out of a local cache and eliminating frequent… Read More »Roundup #45: AWS Secrets Manager, Microservices, ASP.NET Core Architect, WCF vs gRPC
