In this lab, we will create a Kafka producer application using AWS Lambda, which sends fake taxi ride data into a Kafka topic on Amazon MSK. A configurable number of the producer Lambda function will be invoked by an Amazon EventBridge schedule rule. In this way we are able to generate test data concurrently based on the desired volume of messages.
Building Apache Flink Applications in Java by Confluent is a course to introduce Apache Flink through a series of hands-on exercises. Utilising the Flink DataStream API, the course develops three Flink applications from ingesting source data into calculating usage statistics. As part of learning the Flink DataStream API in Pyflink, I converted the Java apps into Python equivalent while performing the course exercises in Pyflink. This post summarises the progress of the conversion and shows the final output.
This series updates a real time analytics app based on Amazon Kinesis from an AWS workshop. Data is ingested from multiple sources into a Kafka cluster instead and Flink (Pyflink) apps are used extensively for data ingesting and processing. As an introduction, this post compares the original architecture with the new architecture, and the app will be implemented in subsequent posts.
This series aims to help those who are new to Apache Flink and Amazon Managed Service for Apache Flink by re-implementing a simple fraud detection application that is discussed in an AWS workshop titled AWS Kafka and DynamoDB for real time fraud detection. In part 1, I demonstrated how to develop the application locally, and the app will be deployed via Amazon Managed Service for Apache Flink in this post.
In this series of posts, we discuss a Flink (Pyflink) application that reads/writes from/to Kafka topics. In the previous posts, I demonstrated a Pyflink app that targets a local Kafka cluster as well as a Kafka cluster on Amazon MSK. The app was executed in a virtual environment as well as in a local Flink cluster for improved monitoring. In this post, the app will be deployed via Amazon Managed Service for Apache Flink.
In this series of posts, we discuss a Flink (Pyflink) application that reads/writes from/to Kafka topics. In part 1, an app that targets a local Kafka cluster was created. In this post, we will update the app by connecting a Kafka cluster on Amazon MSK. The Kafka cluster is authenticated by IAM and the app has additional jar dependency. As Amazon Managed Service for Apache Flink does not allow you to specify multiple pipeline jar files, we have to build a custom Uber Jar that combines multiple jar files. Same as part 1, the app will be executed in a virtual environment as well as in a local Flink cluster for improved monitoring with the updated pipeline jar file.
Apache Flink is widely used for building real-time stream processing applications. On AWS, Amazon Managed Service for Apache Flink is the easiest option to develop a Flink app as it provides the underlying infrastructure. Updating a guide from AWS, this series of posts discuss how to develop and deploy a Flink (Pyflink) application via KDA where the data source and sink are Kafka topics. In part 1, the app will be developed locally targeting a Kafka cluster created by Docker. Furthermore, it will be executed in a virtual environment as well as in a local Flink cluster for improved monitoring.

On AWS, Amazon Managed Service for Apache Flink is the easiest option to develop a Flink app as it provides the underlying infrastructure. Re-implementing a solution from an AWS workshop, this series of posts discuss how to develop and deploy a fraud detection app using Kafka, Flink and DynamoDB. Part 1 covers local development using Docker while deployment via KDA will be discussed in part 2.
In the previous posts, we discussed how to implement client authentication by TLS (SSL or TLS/SSL) and SASL authentication. One of the key benefits of client authentication is achieving user access control. In this post, we will discuss how to configure Kafka authorization with Java and Python client examples while SASL is kept for client authentication.
In the previous post, we discussed TLS (SSL or TLS/SSL) authentication to improve security. It enforces two-way verification where a client certificate is verified by Kafka brokers. Client authentication can also be enabled by Simple Authentication and Security Layer (SASL), and we will discuss how to implement SASL authentication with Java and Python client examples in this post.
