Description

This curriculum reflects the scope typically addressed across a full consulting engagement or multi-phase internal transformation initiative.

Fundamental Architecture and Service Fabric Topology

Evaluate the trade-offs between stateless and stateful services in distributed workloads, including fault tolerance, scalability, and data consistency requirements.
Design cluster topology across availability zones and regions, accounting for latency, quorum requirements, and disaster recovery SLAs.
Implement node types with appropriate VM SKUs, balancing cost, compute density, and service isolation needs.
Configure reliable collections and reliable actors with appropriate partitioning strategies to manage load distribution and avoid hot partitions.
Assess the impact of cluster scaling operations on service availability and quorum stability during peak workloads.
Integrate custom health reporting mechanisms to enable proactive failure detection and automated remediation workflows.
Select between standalone and Azure-hosted clusters based on compliance, control, and operational overhead constraints.
Define upgrade domains and fault domains to align with physical infrastructure boundaries and minimize blast radius during rolling updates.

Service Modeling and Application Lifecycle Management

Structure application manifests to enforce versioned dependencies, side-by-side service coexistence, and backward compatibility.
Orchestrate zero-downtime upgrades using health policies, monitoring thresholds, and manual intervention gates in production.
Manage configuration and code package versioning to prevent unintended rollbacks or configuration drift.
Implement differential upgrades to minimize deployment time and resource consumption during large-scale rollouts.
Enforce deployment validation through pre-upgrade health checks and post-upgrade telemetry verification.
Design service package isolation to prevent cross-service interference during deployment and scaling events.
Automate CI/CD pipelines with environment-specific parameterization while maintaining auditability and rollback capability.
Define service-to-service communication contracts that support version tolerance and graceful degradation.

Reliable State Management and Data Persistence

Configure reliable dictionaries and queues with appropriate consistency modes (strong vs. eventual) based on transactional integrity requirements.
Size and tune replica sets for stateful services, balancing data durability, write throughput, and failover recovery time.
Implement backup and restore policies with retention schedules aligned to RPO and RTO objectives.
Design partition resiliency strategies to handle uneven data distribution and rebalancing during scale-out operations.
Monitor replica lag and quorum formation to detect and mitigate split-brain scenarios in multi-region deployments.
Integrate external data stores with reliable services while managing transaction boundaries and data synchronization overhead.
Optimize checkpointing intervals and log truncation to balance recovery speed and disk I/O pressure.

Security, Identity, and Access Governance

Enforce role-based access control (RBAC) at the cluster, application, and service levels using Azure AD integration.
Implement certificate rotation policies for cluster and service endpoints to maintain compliance without service disruption.
Secure inter-service communication using mutual TLS and service identity claims validation.
Define network security groups and private endpoints to restrict cluster access to authorized subnets and services.
Manage service principal lifecycles and credential rotation for automated deployment and monitoring tools.
Enforce data encryption at rest and in transit, including disk encryption and secure replica communication.
Audit authentication and authorization events to detect anomalous access patterns and privilege escalation attempts.
Isolate sensitive workloads using dedicated node types and security-hardened OS images.

Resilience Engineering and Failure Mode Analysis

Simulate node failures, network partitions, and resource exhaustion to validate service recovery behavior.
Configure health evaluation policies to distinguish transient issues from systemic failures requiring intervention.
Design retry and circuit breaker patterns for service-to-service calls to prevent cascading failures.
Implement chaos engineering practices using controlled fault injection to test failover and recovery workflows.
Monitor replica placement constraints to prevent violations during cluster scaling or node failures.
Define custom health metrics and thresholds that reflect business-critical service behaviors.
Trace fault domains across physical and logical layers to minimize correlated failure risks.
Analyze failover event logs to identify recurring instability patterns and underlying infrastructure issues.

Performance Optimization and Resource Governance

Allocate CPU and memory reservations and limits per service package to prevent resource starvation.
Profile service startup time and replica initialization to meet SLA requirements during failover.
Monitor and tune replica placement algorithms to avoid over-constrained services and placement failures.
Optimize partition count for stateful services to balance load distribution and management overhead.
Measure end-to-end latency across service hops and identify bottlenecks in serialization or transport layers.
Scale stateless and stateful services independently based on observed load patterns and resource utilization.
Use performance counters and ETW traces to diagnose throttling, garbage collection pressure, or thread contention.
Balance cost and performance by rightsizing VM SKUs and node type configurations for specific workloads.

Monitoring, Diagnostics, and Observability

Aggregate and correlate logs from Service Fabric nodes, system services, and custom applications using centralized logging.
Configure event flow from the Diagnostics Extension to Log Analytics, ensuring data freshness and volume thresholds.
Define custom performance and health events to track business-level service degradation.
Map service health to application-level KPIs to enable executive visibility into operational risk.
Use Service Fabric Explorer and PowerShell cmdlets to triage cluster-level issues during incidents.
Implement distributed tracing across microservices to identify latency hotspots and dependency failures.
Set up alerting rules based on health state changes, replica down counts, and placement constraint violations.
Archive diagnostic data to long-term storage for compliance and forensic analysis requirements.

Hybrid and Multi-Cloud Deployment Strategies

Design hybrid clusters that integrate on-premises data centers with Azure for workload portability and data locality.
Manage connectivity between geographically distributed clusters using ExpressRoute or secure VPN tunnels.
Replicate stateful service data across regions using custom sync mechanisms or Azure Data Box solutions.
