Scalable Backends with .NET 8
Building backend systems that handle millions of requests per day requires more than just fast frameworks. It demands disciplined architecture, careful resource management, and a deep understanding of the data layer. .NET 8 delivers on all fronts.

01
Clean Architecture
The Clean Architecture pattern separates concerns into layers: Domain, Application, Infrastructure, and Presentation. In .NET 8, we implement this with class libraries and dependency injection.
var builder = WebApplication.CreateBuilder(args);builder.Services.AddControllers();builder.Services.AddDbContext<AppDbContext>(options => options.UseNpgsql(builder.Configuration.GetConnectionString("Default")));builder.Services.AddScoped<IUnitOfWork, UnitOfWork>();builder.Services.AddScoped<ICollectionService, CollectionService>();var app = builder.Build();app.MapControllers();app.Run();02
EF Core Patterns
Entity Framework Core in .NET 8 introduces complex type mapping, primitive collections, and significant performance improvements. For high-throughput APIs, we use split queries, compiled models, and connection pooling.
03
Performance Tuning
Performance in .NET 8 backends comes from three areas: async I/O, caching, and connection management. We use Polly for resilience, Redis for distributed caching, and PostgreSQL advisory locks for concurrency.
Performance is not an accident. It's the result of thousands of small decisions made correctly.
