Monolith vs Microservices in .NET Core 1. Monolithic Architecture Definition : A single, unified codebase where all modules (UI, business logic, data access) are part of one large application. Deployment : Deployed as a single unit (e.g., one .exe or .dll ). Scaling : Scales by cloning the entire application (vertical/horizontal scaling). Communication : Internal method calls (no network). Tech Stack : Typically limited to a single framework/runtime. Example in .NET Core : An ASP.NET Core MVC app with controllers, services, and EF Core all in the same project. Single database, one codebase, deployed to IIS/Kestrel. 2. Microservices Architecture Definition : A collection of small, independent services, each responsible for a specific business function. Deployment : Each service runs independently (often in Docker containers). Scaling : Scale individual services based on demand. Communication : Via APIs (REST, gRPC, message queues). ...
Certainly, when preparing for an AngularJS interview, it's important to have a solid understanding of the framework, its features, and common development practices. Here are some additional points you might find helpful:
1. AngularJS vs. Angular (Angular 2+): Be prepared to explain the difference between AngularJS and the newer versions of Angular (Angular 2 and above). Mention that AngularJS is sometimes referred to as "Angular 1" and highlight the major architectural changes and improvements introduced in Angular 2+.
2. Directives: Understand that AngularJS heavily relies on directives to extend HTML with new attributes and elements. Familiarize yourself with built-in directives like ng-model, ng-repeat, and ng-if, and explain how to create custom directives.
3. Controllers: Discuss the role of controllers in AngularJS. Controllers are responsible for defining the behavior of a part of the web page. Explain how they are used to manipulate data and interact with the view.
4. Services: Understand the purpose of services in AngularJS. Services are used for sharing data and functionality between different parts of an application. Explain common services like $http and $scope.
5. Dependency Injection: Be able to explain dependency injection in AngularJS and how it aids in creating modular and testable code. Mention how services and components can request dependencies, and how the Angular injector provides them.
6. $scope: Discuss the $scope object, which acts as a bridge between controllers and views. Explain how data is bound to $scope and how changes in the model are automatically reflected in the view due to two-way data binding.
7. Digest Cycle: Describe the AngularJS digest cycle, which is responsible for tracking changes in the model and updating the view. Understand how it works and the role of dirty checking.
8. Filters: Discuss the use of filters in AngularJS to format and transform data in the view. Mention common filters like date, uppercase, and number, and provide examples of their usage.
9. Routing: Be able to explain how client-side routing works in AngularJS using the $routeProvider. Describe how it enables single-page applications and navigation without full page reloads.
10. Testing: Know the importance of testing in AngularJS development. Explain how tools like Jasmine and Karma can be used for unit testing AngularJS applications, and discuss the benefits of test-driven development.
11. Best Practices: Understand and be prepared to discuss best practices for AngularJS development, including the use of modules, proper folder structure, and the separation of concerns.
12. Real-World Experience: Be ready to provide examples from your previous work where you've used AngularJS. Discuss challenges you've faced and how you overcame them.
In addition to these technical aspects, be sure to demonstrate problem-solving skills and your ability to adapt to different scenarios when working with AngularJS. This will show potential employers that you not only understand the technology but can also apply it effectively.
