When Your Cloud App Calls Itself: The Hidden Cost of Loopback Connections Most performance issues don’t come from exotic bugs or mysterious cloud failures.They come from well-intentioned design decisions that quietly stop scaling. One of the most common—and least understood—examples I see in cloud applications is this: An application makes HTTP calls back to itself.Continue reading “Understanding Loopback Connections in Cloud Apps”

Mastering Network Traces with Wireshark: A Guide for App Engineers
The Wireshark Cheat Sheet Every Azure App Service Engineer Needs (But Nobody Tells You About) Why network traces feel like reading hieroglyphics—and how to actually understand them After years of debugging critical Azure App Service escalations at 2 AM, I’ve learned something important: the gap between “my application is slow” and “here’s exactly why” isContinue reading “Mastering Network Traces with Wireshark: A Guide for App Engineers”
Boost Your App Performance with Azure’s Intelligent SRE Agent
What Happens When AI Meets the Azure SRE AGENT? It Writes the Fix. Meet the Azure SRE Agent — an intelligent, autonomous system purpose-built to raise the bar on application reliability. It continuously monitors your applications in real time, detects abnormal behavior, diagnoses root causes at the code level, and proposes (or implements) precise, production-safeContinue reading “Boost Your App Performance with Azure’s Intelligent SRE Agent”
Effective Memory Dump Capture in Azure: Portal vs. Procdump
Why Capturing Memory Dumps in Azure App Service Is Best Done Through the Portal (Not procdump) When an application slows down, crashes unexpectedly, or consumes more resources than it should, capturing a memory dump is one of the fastest ways to diagnose the root cause. Memory dumps allow engineers to inspect what’s happening inside theContinue reading “Effective Memory Dump Capture in Azure: Portal vs. Procdump”
Azure App Service Authentication: Security Challenges
By Chris Corder | Senior Technical Advisor, Microsoft Azure#Azure #AppService #Authentication #CloudSecurity In today’s cloud-first world, securing user sessions isn’t just important, it’s essential. Azure App Service makes authentication easier than ever with its built-in Authentication and Authorization feature, commonly known as Easy Auth. It enables developers to integrate identity providers like Azure AD, Google,Continue reading “Azure App Service Authentication: Security Challenges”

Why Is WebSocketMonitoringModule Throwing 500 Errors When WebSockets Are Disabled?
If you’ve ever poked around the diagnostics blade in Azure App Service and spotted a bunch of 500 errors blamed on something called WebSocketMonitoringModule, you’re probably thinking: “Wait… what? I didn’t even turn on WebSockets!” And you’d be right. You scroll back through your app settings, double-check the config (yep, WebSockets: Off), and yet thereContinue reading “Why Is WebSocketMonitoringModule Throwing 500 Errors When WebSockets Are Disabled?”

Performance Considerations Between Lua Scripts and Basic Commands in Redis for Cloud Applications
Choosing Between Lua Scripts and Basic Commands in Redis for Cloud Applications When using Redis—whether on Azure or elsewhere—the decision between Lua scripts and basic commands (such as StringSet) can significantly impact both performance and maintainability. Redis is widely used in cloud environments for caching, session management, and real-time analytics due to its high-speed in-memoryContinue reading “Performance Considerations Between Lua Scripts and Basic Commands in Redis for Cloud Applications”
Understanding ARR Affinity for Stateful Applications
=============================================== Overview:Application Request Routing (ARR) Affinity is often discouraged in cloud-native architectures due to concerns about scalability, resiliency, and performance. However, there are specific scenarios where enabling ARR Affinity in Azure Web Apps can be beneficial and even necessary to maintain application functionality and improve the user experience. This article outlines the advantages of ARRContinue reading “Understanding ARR Affinity for Stateful Applications”
