Apache Kafka Administration by Confluent

Course Objectives

During this hands-on course you will learn how:

• Kafka and the Confluent platform work, and how their main subsystems interact 
• To set up, manage, monitor and tune your cluster 
• To use industry best practices developed by the world's foremost Apache Kafka experts

Hands-on Training 

Throughout the course, hands-on exercises reinforce the topics being discussed. Exercises include:

• Using Kafka's command-line tools
• Exploring configuration
• Using Kafka's administrative tools
• Tuning Producer and Consumer performance
• Securing the cluster 
• Building data pipelines with Kafka Connect

This course is designed for System Administrators and Operations staff responsible for building, managing, monitoring, and tuning Kafka clusters and components of Confluent Platform. Architects and DevOps staff who want a tour on how the Central Services (Kafka, KRaft, Schema Connect, Registry, etc.) work are also welcome.

Attendees should have a working knowledge of the Kafka architecture. It is also important to have strong knowledge of Linux/Unix and understand basic TCP/IP networking concepts. Familiarity with Java Virtual Machine (JVM) is helpful. Participants are required to provide a laptop computer with unobstructed internet access to fully participate in the class.
