Key training modules
Comprehensive, hands-on modules designed to take you from basics to advanced concepts
- Module 1: Service Mesh Fundamentals (Why It Exists)
- What a service mesh is and where it fits in cloud-native architecture
- Why microservices need a mesh (security, traffic control, observability, policy)
- What a mesh is not (avoid confusion with API gateways and ingress)
- Common use cases in enterprises (compliance, multi-team reliability, zero trust)
- Hands-on: Activity: Identify which problems in a microservices system require a mesh vs native Kubernetes features
- Module 2: Problems a Service Mesh Solves (Security, Traffic, Observability, Policy)
- Secure service-to-service communication as a default requirement
- Traffic control without changing application code
- Observability for service interactions (latency, errors, dependencies)
- Policy enforcement and governance across teams
- Hands-on: Workshop: Map a sample microservices architecture to mesh capabilities and outcomes
- Module 3: Service Mesh Architecture (Data Plane vs Control Plane)
- Data plane vs control plane responsibilities
- Sidecar proxy model and traffic interception concepts
- Service identity and workload authentication concepts
- mTLS fundamentals (cert issuance, rotation concepts)
- Hands-on: Lab: Deploy a mesh and inspect sidecars, listeners, and workload identity signals
- Module 4: mTLS Implementation (Encryption and Authentication Between Services)
- mTLS modes (permissive vs strict concepts)
- Certificate management and rotation awareness
- Enforcing encrypted in-cluster traffic
- Validating mTLS status and troubleshooting common issues
- Hands-on: Lab: Enable mTLS for a microservices app and verify encrypted and authenticated traffic
- Module 5: Microservices Security Fundamentals with the Mesh (Zero Trust and Least Privilege)
- Zero trust inside clusters and why it matters
- Least privilege access patterns (service-to-service authorization concepts)
- Strong authentication between services using service identity
- Policy design patterns (allowlists, deny-by-default concepts)
- Hands-on: Lab: Apply authorization policies to restrict which services can call each other
- Module 6: Traffic Management Policies (Routing, Retries, Timeouts, Circuit Breakers)
- Traffic routing rules (version routing, canary concepts)
- Retries and timeouts and their impact on reliability
- Circuit breaker concepts and outlier detection patterns
- Safe rollout patterns using mesh traffic control
- Hands-on: Lab: Implement routing + retries + timeouts and validate behavior under failure
- Module 7: Resilience Patterns in the Mesh (Fault Injection and Rate Limiting)
- Fault injection concepts (delay, abort) for testing resilience
- Rate limiting concepts (protect upstream dependencies)
- Load shedding and backpressure awareness
- Chaos testing practices for microservices with the mesh
- Hands-on: Lab: Inject faults and validate that resilience controls reduce impact and improve stability
- Module 8: Observability with Service Mesh (Metrics, Tracing, Dependency Views)
- Service-to-service metrics (latency, error rate, traffic volume)
- Distributed tracing concepts and correlation across services
- Dependency visualization and service graph interpretation
- Golden signals and alerting concepts for service interactions
- Hands-on: Lab: Visualize dependencies and troubleshoot an incident using mesh telemetry signals
- Module 9: Operating a Mesh in Production (Onboarding, Upgrades, Failure Modes)
- Workload onboarding patterns (namespace labeling, gradual adoption)
- Overhead awareness (latency, CPU/memory, scaling impacts)
- Upgrade strategies and compatibility considerations
- Common failure modes (cert issues, sidecar injection problems, policy breakages)
- Hands-on: Lab: Perform a safe onboarding and simulate a failure mode to practice recovery
- Module 10: Capstone Project (Service Mesh Deployment with Security Policies)
- Capstone goal: Deliver a secured microservices deployment using a service mesh
- Deploy a multi-service application and onboard it to the mesh
- Enable and enforce mTLS across services
- Apply least privilege authorization policies and validate access boundaries
- Implement traffic controls (retries/timeouts) and add an observability view
- Hands-on: Capstone Lab: Demo secure communication, controlled routing, and t
