2. Agenda
• Need Of Messaging Systems
• Apache Kafka Architecture and Terminology
• Zookeeper
• Apache Kafka Use cases
• Apache Kafka Installation
• Apache Kafka Integration with Spring Boot

3. Introduction
In today’s world, data is the main ingredient of internet applications and
typically encompasses the following :
• Page visits and clicks
• User activities
• Events corresponding to logins
• Social networking activities such as likes, shares and comments
• Application-specific metrics (e.g. logs, page load time, performance etc.)

4. Uses of Data
Applications data can be used to run analytics in real time serving
various purposes, some of which are:
• Delivering advertisements
• Tracking abnormal user behaviors
• Displaying search based on relevance
• Showing recommendations based on previous activities

6. Complex Data Pipelines

7. Why Messaging Systems ?
• Problem: Collecting all the data is not easy as data is generated from
various sources in different formats
• Solution: One of the ways to solve this problem is to use a messaging
system. Messaging systems provide a seamless integration between
distributed applications with the help of messages.

18. Zookeeper
• Apache Zookeeper is a software project of the Apache Software
Foundation. It is essentially a centralized service for distributed
systems to a hierarchical key-value store, which is used to provide a
distributed configuration service, synchronization service, and naming
registry for large distributed systems.
• Zookeeper was a sub-project of Hadoop but is now a top-level Apache
project in its own right.
