Rethinking Stream Processing with Apache Kafka, Kafka Streams and KSQL

Posted in Apache Kafka, Big Data, Docker, Java / JEE, Kafka Streams, KSQL, Kubernetes, Messaging, Microservices, Open Source, Stream Processing on March 13th, 2018 by admin

I presented at JavaLand 2018 in Brühl recently. A great developer conference with over 1800 attendees. The location is also awesome! A theme park: Phantasialand. My talk: “New Era of Stream Processing with Apache Kafka’s Streams API and KSQL“. Just want to share the slide deck…

Kai Speaking at JavaLand 2018 about Kafka Streams and KSQL

Abstract

Stream Processing is a concept used to act on real-time streaming data. This session shows and demos how teams in different industries leverage the innovative Streams API from Apache Kafka to build and deploy mission-critical streaming real time application and microservices.

Visualisation from my Apache Kafka + Mesos Session at OOP 2018

Posted in Apache Kafka, Apache Mesos, Big Data, Kafka Connect, Kafka Streams, KSQL, Kubernetes, Microservices, Open Source on February 18th, 2018 by Kai Wähner

I did some talks about “Apache Kafka + Apache Mesos = Highly Scalable Microservices” in the last months… See my blog post with notes and slides from MesosCon Europe.

I did an updated version at OOP 2018 conference in Munich. The conference organizers invited some great people who do live drawings during some of the talks. The result of the live whiteboard drawing of my session is really awesome. Take a look:

Thanks to the guys from Remarker. Great visualisation! Love it…

Machine Learning Trends of 2018 combined with the Apache Kafka Ecosystem

Posted in Analytics, Apache Kafka, Apache Spark, Big Data, Business Intelligence, Confluent, Deep Learning, Kafka Streams, KSQL, Kubernetes, Machine Learning, Microservices, Open Source, Stream Processing on February 13th, 2018 by Kai Wähner

At OOP 2018 conference in Munich, I presented an updated version of my talk about building scalable, mission-critical microservices with the Apache Kafka ecosystem and Deep Learning frameworks like TensorFlow, DeepLearning4J or H2O. I want to share the updated slide deck and discuss a few updates about newest trends, which I incorporated into the talk.

Apache Kafka + Kafka Streams + Mesos = Highly Scalable Microservices

Posted in Apache Kafka, Apache Mesos, Big Data, Confluent, Docker, Java / JEE, Kafka Streams, KSQL, Microservices, Middleware, Open Source, Stream Processing on January 12th, 2018 by Kai Wähner

My latest article about Apache Kafka, Kafka Streams and Apache Mesos was published on Confluent’s blog:

Apache Mesos, Apache Kafka and Kafka Streams for Highly Scalable Microservices

This blog post discusses how to build a highly scalable, mission-critical microservice infrastructure with Apache Kafka, Kafka Streams, and Apache Mesos respectively in their vendor-supported platforms from Confluent and Mesosphere.

Apache Mesos, Apache Kafka and Kafka Streams for Highly Scalable Microservices

Have fun reading it and let me know if you have any feedback…

Apache Kafka + Kafka Streams + Mesos / DCOS = Scalable Microservices

Posted in Apache Kafka, Apache Mesos, Big Data, Confluent, Docker, Hadoop, Java / JEE, Kafka Connect, Kafka Streams, KSQL, Kubernetes, Microservices, Open Source on October 27th, 2017 by Kai Wähner

I had a talk at MesosCon 2017 Europe in Prague about building highly scalable, mission-critical microservices with Apache Kafka, Kafka Streams and Apache Mesos / DCOS. I would like to share the slides and a video recording of the live demo.

Abstract

Microservices establish many benefits like agile, flexible development and deployment of business logic. However, a Microservice architecture also creates many new challenges. This includes increased communication between distributed instances, the need for orchestration, new fail-over requirements, and resiliency design patterns.

Deep Learning in Real Time with TensorFlow, H2O.ai and Kafka Streams (Slides from JavaOne 2017)

Posted in Analytics, Apache Kafka, Big Data, Business Intelligence, Confluent, Deep Learning, Docker, Java / JEE, Kafka Streams, Machine Learning, Microservices, Open Source, Stream Processing on October 4th, 2017 by Kai Wähner

Early October… Like every year in October, it is time for JavaOne and Oracle Open World in San Francisco… I am glad to be back at this huge event again. My talk at JavaOne 2017 was all about deployment of analytic models to scalable production systems leveraging Apache Kafka and Kafka Streams. Let’s first look at the abstract. After that I attach the slides and refer to further material around this topic.

Kafka Streams + H2O.ai + TensorFlow (Video Recording / Live Demo)

Posted in Analytics, Apache Kafka, Big Data, Kafka Streams, Machine Learning, Open Source, Stream Processing on September 7th, 2017 by Kai Wähner

I do a lot of presentations these days at meetups and conferences with one focus: How to leverage Apache Kafka and Kafka Streams to apply analytic models (built with H2O, TensorFlow, DeepLearning4J and other frameworks) to scalable, mission-critical environments. As many attendees have asked me, I created a video recording about this talk (focusing on live demos).

Apache Kafka Streams + Machine Learning (Spark, TensorFlow, H2O.ai)

Posted in Analytics, Apache Kafka, Apache Spark, Big Data, Confluent, Hadoop, Integration, Kafka Connect, Kafka Streams, Machine Learning, Messaging, Microservices, Open Source, Stream Processing on May 23rd, 2017 by Kai Wähner

I started at Confluent in May 2017 to work as Technology Evangelist focusing on topics around the open source framework Apache Kafka. I think Machine Learning is one of the hottest buzzwords these days as it can add huge business value in any industry. Therefore, you will see various other posts from me around Apache Kafka (messaging), Kafka Connect (integration), Kafka Streams (stream processing), Confluent’s additional open source add-ons on top of Kafka (Schema Registry, Replicator, Auto Balancer, etc.). I will explain how to leverage all this for machine learning and other big data technologies in real world production scenarios.

Why I Move (Back) to Open Source for Messaging, Integration and Stream Processing

Posted in Analytics, API Management, Big Data, Blockchain, Cloud, Cloud-Native, Docker, ESB, Hadoop, Internet of Things, Java / JEE, Machine Learning, Microservices, Middleware, SOA on May 1st, 2017 by Kai Wähner

After three great years at TIBCO Software, I move back to open source and join Confluent, a company focusing on the open source project Apache Kafka to build mission-critical, scalable infrastructures for messaging, integration and streaming analytics. Confluent is a Silicon Valley startup, still in the beginning of its journey, with a 700% growing business in 2016, and is exjustpected to grow significantly in 2017 again.

In this blog post, I want to share why I see the future for middleware and big data analytics in open source technologies, why I really like Confluent, what I will focus on in the next months, and why I am so excited about this next step in my career.
