Microservices

 




Health checks of all microservices

Logging from all microservices











preferable using messaging if possible



Event functions.  Bindings in Azure functions remove need to write boiler plate code.



Order class just has everything to do with adding and maintaining an order but nothing to do with database or any other logic.

Domain model classes do not contain any data access code.


This is where you have the repository layer.





As database query is hardcoded into the function this cannot be mocked.  We need to use an abstraction.

Microservices and Service-Oriented Architecture

  Microservices Architecture and Service-Oriented Architecture (SOA) , along with their similarities, differences, and typical use cases. Microservices Architecture Microservices is an architectural style where applications are composed of small, independent services that communicate over a network. Each service is typically designed around a specific business function and operates as an isolated, self-contained unit. Here are some key characteristics: Independently Deployable : Each service can be developed, deployed, and scaled independently of others. Single Responsibility : Services are organized around business capabilities, such as “Order Processing” or “User Authentication.” Resilience : Each microservice operates independently, making the system more resilient since failures in one service do not necessarily impact others. Polyglot Persistence and Programming : Microservices allow for diverse technologies, frameworks, and databases across services, optimizing each service...

Version control and Continuous Integration/Continuous Deployment (CI/CD)

 Version control and Continuous Integration/Continuous Deployment (CI/CD) are fundamental practices in modern software development that enhance collaboration, maintainability, and quality of software projects. Below, we’ll explore each concept, including their principles, benefits, and key practices. Version Control Version Control is a system that records changes to files or sets of files over time, allowing developers to track and manage changes to their codebase. It facilitates collaboration among team members and provides a history of changes, making it easier to revert to previous versions if needed. Key Principles of Version Control Track Changes : Every change made to the codebase is recorded, allowing developers to see who made changes, what changes were made, and when. Branching and Merging : Developers can create branches to work on features or fixes in isolation without affecting the main codebase (usually referred to as the main or master branch). Once the work is co...

Delegates

 In C#, delegates are types that represent references to methods. They can be used to define callback methods, event handlers, and can also be used in functional programming patterns. Below is a list of commonly used delegates in C#, including built-in delegates and custom delegates. Built-in Delegates Action : Represents a delegate that can point to a method that does not return a value. It can take up to 16 parameters. Examples : Action (no parameters) Action<T> (one parameter) Action<T1, T2> (two parameters) Action<T1, T2, T3> (three parameters) ... Action<T1, T2, ..., T16> (up to 16 parameters) csharp Copy code // Example Action< string > print = message => Console.WriteLine(message); Func : Represents a delegate that can point to a method that returns a value. It can also take up to 16 parameters. Examples : Func<TResult> (no parameters) Func<T1, TResult> (one parameter) Func<T1, T2, TResult> (two parameters) Func<...
