Course Outline
Essentials of Kafka Administration
- The role of Kafka within a modern data platform and typical production responsibilities
- Core concepts for operators: brokers, topics, partitions, offsets, and consumer groups
- Fundamentals of replication: leaders and followers, in-sync replicas, and availability trade-offs
- Key operational highlights and common terminology found in runbooks
KRaft Mode and Cluster Design
- KRaft basics: controllers, metadata quorum, elections, and their operational significance
- Deployment planning: sizing for throughput, partitions, retention policies, and future growth
- Node roles and layouts: combined versus dedicated controllers, and fault domain considerations
- Lab: Inspect KRaft metadata, validate quorum health, and interpret controller logs
Installation, Configuration, and Day-to-Day Operations
- Installation methods (packages, tarball, containers) and standardization in enterprise environments
- Core broker configuration impacting reliability: listeners, replication, log directories, and retention
- Safe service operations: startup sequence, graceful shutdown, and validation checks
- Lab: Deploy a multi-node cluster, verify broker registration, and confirm baseline produce and consume functionality
Managing Topics, Partitions, and Data Placement
- Topic lifecycle management using the Kafka CLI: create, describe, update configurations, and delete
- Selecting partitions and replication factors for real-world workloads, including identification of common anti-patterns
- Reassignments and balancing: determining when to move partitions and verifying progress safely
- Lab: Create topics, trigger a partition reassignment, simulate a broker outage, and confirm recovery
Securing Kafka for Production
- TLS for client and inter-broker traffic: certificates, trust chains, and validation steps
- Authentication with SASL: selecting common mechanisms and avoiding misconfiguration
- Authorization with ACLs: implementing least-privilege patterns for admins, producers, and consumers
- Lab: Enable TLS and SASL, validate client connectivity, and apply ACLs for application roles
Observability, Reliability, and Troubleshooting
- Monitoring essentials: controller health, under-replicated partitions, request latency, and disk and network saturation
- Logs and metrics: interpreting broker logs and exposing metrics via JMX exporter to common observability stacks
- Operational playbooks: rolling restarts, safe configuration changes, and handling disk-full and ISR issues
- Lab: Build a minimal alert set, diagnose a degraded cluster, and restore healthy replication
Upgrades and Disaster Recovery Readiness
- Upgrade planning for Kafka: compatibility checks, staging, and rollback strategies
- Backup and recovery expectations: what can be backed up, what cannot, and basics of configuration recovery
- Cross-cluster replication overview and when to use MirrorMaker 2 for disaster recovery and migrations
- Wrap-up: operational checklist, handover artifacts, and next steps for production rollout
Requirements
- A foundational understanding of basic Linux administration (including users, services, files, and permissions)
- Experience with TCP/IP networking concepts (DNS, ports, firewalls, and load balancers)
- Basic scripting proficiency (Bash, PowerShell, or similar) for routine operational tasks
Audience
- Kafka administrators and platform engineers responsible for the operation of Kafka clusters
- Site reliability engineers and DevOps engineers supporting streaming platforms
- Infrastructure and operations teams deploying new KRaft-based Kafka clusters or migrating from ZooKeeper
