With the release of Azure Functions 4.0 (running on .NET 6), the performance landscape for serverless has shifted dramatically. Upgrading from 3.0 (.NET Core 3.1) isn’t just a version bump; it is an overhaul of the worker process. Cold Start Analysis The “Cold Start” is the time it takes for Azure to provision your instance […]

Playwright vs Selenium in 2021
For a decade, Selenium was the king of E2E testing. But modern SPAs (React/Vue) flakiness made it painful. Microsoft’s Playwright (fork of Puppeteer) offers a faster, more reliable alternative by using the DevTools Protocol directly. Auto-Waiting Playwright waits for elements to be actionable checks prior to performing actions. No more `Thread.Sleep(5000)`! Browser Contexts Run isolated […]

Clean Architecture (Robert C. Martin) separates concerns into concentric rings, with the Domain at the center. Dependencies point inward. We implement this in .NET 5. The Layers The Dependency Rule The Application layer defines interfaces (e.g., `IOrderRepository`), but the Infrastructure layer implements them. This “Inversion of Control” keeps the core independent of the database. Key […]

Historically, Logic Apps were a shared SaaS offering. Logic Apps “Standard” creates a single-tenant runtime (on top of Azure Functions), enabling local development, VNET integration, and reliable performance without “noisy neighbors.” Local Development in VS Code Since it’s built on the Functions runtime, you can run workflows locally! Stateful vs Stateless **Stateful**: Default. Checkpoints every […]
Read more →Kubernetes Architecture: Beyond the Basics
You know Pods and Services. But to run K8s in production, you need to understand the Control Plane, Etcd consistency, and the Scheduler’s decision-making process. Control Plane Internals The Reconciliation Loop Kubernetes is basically a set of infinite loops checking `Current State == Desired State`. If not, it acts. Key Takeaways **Etcd** is the brain; […]
Read more →.NET 5 Migration: Real World Lessons
Migrating a large enterprise monolith to .NET 5 is different from upgrading a “Hello World” app. We share lessons learned from migrating 50+ microservices, including handling breaking changes in ASP.NET Core and Entity Framework. Breaking Change: JSON Serialization System.Text.Json is the default now. If you rely heavily on Newtonsoft.Json quirks, switching is painful. Target Framework […]
