- Course Overview
- This advanced course offers an intensive dive into designing, implementing, and managing highly secure, performant, and resilient network and infrastructure solutions for Kubernetes and Azure Kubernetes Service (AKS). It’s tailored for professionals aiming to master cloud-native networking beyond basic deployments.
- You will deeply explore the core network architecture of Kubernetes, covering pod communication, service exposure, and advanced external traffic routing, all framed by production-grade considerations and best practices.
- The curriculum extensively covers critical components: Container Network Interface (CNI) plugins, sophisticated network policy enforcement, multi-layered ingress strategies, and robust egress traffic management for comprehensive control over network flows.
- A significant focus integrates AKS with advanced Azure networking services, including Virtual Networks (VNets), NSGs, Azure Firewall, and Application Gateways, to build enterprise-ready, compliant infrastructure.
- Beyond configuration, the course emphasizes network performance optimization, advanced troubleshooting techniques, and implementing high availability from a network perspective.
- Youβll gain practical insights into leveraging service mesh technologies (e.g., Istio, Linkerd) for advanced traffic control, enhanced observability, and establishing a zero-trust security model through mutual TLS (mTLS).
- Requirements / Prerequisites
- Intermediate Kubernetes Experience: Solid understanding of core Kubernetes primitives (Pods, Deployments, Services, Namespaces) and proficiency with `kubectl` for basic cluster operations.
- Cloud Networking Fundamentals (Azure Preferred): Familiarity with essential cloud networking concepts: Virtual Networks, subnets, routing, Network Security Groups (NSGs), and load balancers, especially within Azure.
- Linux Networking Basics: Fundamental knowledge of Linux networking concepts like IP addressing, basic routing, and DNS resolution.
- Command Line Interface (CLI) Proficiency: Comfort using Azure CLI for Azure resource management and `kubectl` for Kubernetes cluster interaction.
- YAML Configuration Acumen: Ability to proficiently read, write, and modify Kubernetes resource definitions in YAML format.
- Basic Security Awareness: Understanding of core cybersecurity principles (e.g., encryption, firewalls, access control) to contextualize security modules.
- Skills Covered / Tools Used
- Advanced CNI Plugin Configuration: Master setup and fine-tuning of CNI plugins (Azure CNI, Kubenet, Calico, Cilium), optimizing for IP allocation, network policy enforcement, and performance.
- Sophisticated Network Policy Design: Develop and apply advanced Kubernetes Network Policies to implement micro-segmentation, control east-west traffic, and enforce granular ingress/egress security rules.
- Multi-Layered Ingress & Egress Strategies: Implement various Ingress Controllers (NGINX, AGIC) for advanced traffic management (A/B testing, URL rewrites) and configure Azure Firewall/UDRs for secure egress traffic.
- Service Mesh Integration (e.g., Istio, Linkerd): Deploy and manage service mesh solutions for advanced traffic control (circuit breaking, retries), enforce mTLS for zero-trust security, and gain deep observability.
- Deep AKS-Azure Networking Integration: Learn to integrate AKS seamlessly with Azure VNets, Private Endpoints, Private Link, and VNet Peering for robust hybrid connectivity and private API server access.
- Custom DNS Management: Configure CoreDNS, integrate with external DNS providers via ExternalDNS, and troubleshoot complex DNS resolution issues within the cluster.
- Network Observability and Troubleshooting: Utilize tools like `tcpdump`, Azure Monitor, Prometheus, and Grafana to monitor network performance, pinpoint bottlenecks, and diagnose connectivity and latency problems.
- Advanced Load Balancing & Traffic Routing: Implement internal and external load balancers, explore session affinity, and configure advanced health probes for highly available service delivery.
- Network Security Governance & Compliance: Apply Azure Policy and Open Policy Agent (OPA) with Gatekeeper for policy-as-code to enforce network security standards and ensure compliance.
