In a previous project, we had to decide between round-robin and least-connections load balancing for our Nginx setup. I chose least-connections as our application was resource-intensive and had variable load,…

Middleware in Go’s HTTP package refers to a function that wraps an HTTP handler to modify its behavior, such as adding logging, authentication, or response compression. It’s beneficial for separating…

I would use a Model-View-ViewModel (MVVM) architecture combined with Combine for reactive programming. This allows for a clear separation of concerns while ensuring real-time updates are efficiently propagated to the…

I would create a well-defined architecture using interfaces and type guards to ensure type safety across the application. Key components should include a clear separation between data processing, model handling,…

When choosing a framework for microservices, I consider factors such as scalability, language compatibility, ecosystem support, and ease of integration. Additionally, I assess how well the framework aligns with our…

Microservices improve scalability by allowing individual services to be scaled independently based on demand. In a monolithic architecture, scaling typically requires duplicating the entire application, which is less efficient and…

To handle event deduplication, I would implement an idempotency key system where each event is tagged with a unique identifier. This allows us to track events that have already been…

To optimize the database access layer for heavy reads in a Next.js application, I would implement caching mechanisms, use a read replica for the database, and ensure that queries are…

I would implement a caching mechanism using a combination of in-memory caching like Redis for frequently accessed data and a file-based cache for less frequently accessed data. Key considerations include…

I would use the Flutter BLoC pattern for state management to separate business logic from the UI. Structuring the app into multiple widgets and folders for features also helps in…

Nginx uses an event-driven architecture which allows it to handle a large number of concurrent connections efficiently. It primarily uses a combination of epoll on Linux and the worker process…

Service discovery is a mechanism that allows microservices to find and communicate with each other dynamically. It is important because it helps manage the resilience and scalability of the application…
