🛠️ Production Runbook & Step-by-Step Resolution
1️⃣
The Core Enterprise Azure Portfolio
Services implemented in production architectures:
- Azure Kubernetes Service (AKS): Managed container orchestration with Azure CNI, managed node pools (Ubuntu/Azure Linux), and cluster autoscaler.
- Azure Key Vault (AKV): Hardware-backed HSM secret, certificate, and cryptographic key store; integrated with AKS via Azure Key Vault Secrets Provider / External Secrets Operator.
- Azure Container Registry (ACR): Enterprise private Docker registry with Geo-replication, automated vulnerability scanning (Microsoft Defender for Cloud), and task webhooks.
- Microsoft Entra ID (formerly Azure AD) & Workload Identity: Zero-trust identity; replaces long-lived credentials by federating Kubernetes ServiceAccounts directly to Azure Managed Identities.
2️⃣
Networking & Observability Pillars
Network boundary and telemetry backbone:
- Virtual Networks (VNet) & Network Security Groups (NSGs): Subnet segmentation, peering with on-prem ExpressRoute, Private Endpoints for PaaS services, and NSG stateful packet filtering.
- Azure Application Gateway & AGIC: Layer 7 load balancer with integrated WAF v2 routing directly to AKS pods via Application Gateway Ingress Controller.
- Azure Monitor & Log Analytics Workspaces: Centralized telemetry sink collecting Kusto Query Language (KQL) logs from AKS container stdout, audit logs, and metrics alerts.
💡 The Senior SRE Gold Nugget (Key Architectural Takeaway)
"A modern Azure DevOps stack integrates AKS with Azure Key Vault for secrets, ACR for geo-replicated secure images, Entra ID Workload Identity for passwordless IAM, VNets with Private Endpoints for network isolation, and Log Analytics with KQL for telemetry."
⚡ 60-Second Elevator Pitch Talking Points
- Compute: Azure Kubernetes Service (AKS) with system and user node pools.
- Security & Secrets: Azure Key Vault integrated via Workload Identity (no hardcoded passwords).
- Registries: Azure Container Registry (ACR) with Defender vulnerability scanning and geo-replication.
- Networking: VNet, subnets, NSGs, Private Endpoints (no public IPs on DBs), and Azure Application Gateway (AGIC).
- Observability: Azure Monitor, Container Insights, and Log Analytics workspaces using KQL queries.
