If Azure WAF is blocking legitimate traffic after a policy update, new deployment, or rule set upgrade, false positives are the most common cause. This guide walks through 7 diagnostic phases to identify, reproduce, and safely exclude the offending rule — without disabling WAF protection.
If your VPN Gateway CPU is above 85% while traffic volume looks normal, BGP route bloat is almost certainly the cause. This guide covers the exact commands to diagnose it, route summarization on the CE router, an Azure-side prefix filter for defense in depth, and when to upgrade the gateway SKU.
If your enterprise SSO logins are returning AADSTS errors, redirect_uri mismatches, or silent token refresh failures, this guide walks through 8 diagnostic steps to locate and fix the root cause — covering OAuth 2.0, OIDC, Entra ID app registration, and high-availability token caching.
If some pods in your AKS cluster resolve external DNS names fine and others fail — from the same Deployment, same image, same config — the variable is the node. This guide covers the exact test sequence to isolate CoreDNS upstream forwarding failures, identify /etc/resolv.conf drift on worker nodes, and fix it without reprovisioning.
If your ExpressRoute Gateway shows BGP Connected but cross-premises traffic is down and effective routes on spoke VNet NICs are empty, the gateway has a control-plane failure. This guide covers the diagnostic commands to confirm it, a regional failover procedure, and the zone-redundant HA architecture to prevent recurrence.
An honest comparison of Terraform and Bicep for Azure infrastructure in 2026. When each tool wins, where each hurts, and the hybrid pattern most real teams end up adopting.
Three Azure services now offer serious vector search capabilities. Azure AI Search, Cosmos DB for NoSQL, and Azure Database for PostgreSQL with pgvector each have a distinct sweet spot. Here is which to use and when.
Three serious options exist for building AI agents on Azure, and they solve different problems. Azure AI Agent Service is fully managed but opinionated. Semantic Kernel is Microsoft-native and enterprise-ready. LangChain is flexible but complex. Here is how to choose.
If your Azure OpenAI calls fail after adding a private endpoint — with timeouts, 401s, or connections that bypass the endpoint entirely — the cause is almost always in one of four places: DNS resolution, App Service VNet routing, NSG subnet policies, or SDK endpoint configuration. Here is how to diagnose and fix each one.
Prompt injection is the SQL injection of the AI era. Unlike traditional vulnerabilities, it requires no code exploit — just carefully crafted text. Here are the seven patterns attackers use and the Azure defenses that stop them.
Prompts are code. They need version control, testing, deployment pipelines, and rollback strategies. Most teams treat them like config files and wonder why their AI quality is inconsistent. Here is how to manage prompts properly.
Most teams instrument their AI apps with latency and error rate dashboards. Those are necessary but not sufficient. The failures that hurt production AI are invisible to standard APM tooling. Here are the four signals that actually matter.
Pure vector search sounds like the obvious choice for RAG. In practice, it misses exact matches, product codes, and proper nouns that keyword search catches trivially. Hybrid search using RRF consistently outperforms either approach alone.
Chunking is the step most teams rush past when building RAG systems. The wrong chunking strategy makes your search retrieve the right document but the wrong passage — and the LLM hallucinates the rest. Here is what works.
Not every Azure OpenAI deployment should look the same. Direct API, APIM gateway, and private VNet topologies each solve a different set of requirements. Here is when to use each one.
Deploying Azure OpenAI in a demo is easy. Running it in production at scale is a different problem. Here are the seven failure modes we hit repeatedly — and how to fix them before they hit you.
Your AI app can fail even when nothing is technically broken. The server is healthy, the API is fast, the dashboards are green — but your chatbot still gives a completely wrong answer. That is the weird thing about GenAI systems.
