SpringOne Platform 2016 Replay: I can't believe it's not a queue: Using Kafka with Spring

Recorded at SpringOne Platform 2016.
Speaker: Joe Kutner, Confluent
Slides: http://www.slideshare.net/SpringCentral/i-cant-believe-its-not-a-queue-using-kafka-with-spring

Your existing message system is great, until it gets overloaded. Then what? That’s when you should try Kafka.

Kafka is designed to be resilient. It takes the stress out of moving from a Spring monolith into a scalable system of microservices. Since you can capture every event that happens in your app, it’s great for logging. You can even use Kafka’s distributed, ordered log to simulate production load in your staging environment.

SpringOne Platform 2016 Replay: Architecting for cloud native data: Data Microservices done right using Spring Cloud

Recorded at SpringOne Platform 2016.
Speaker: Fred Melo
Slides: http://www.slideshare.net/SpringCentral/architecting-for-cloud-native-data-data-microservices-done-right-using-spring-cloud-64889916

Microservices are definitely offering best practice guidance for those architecting cloud native applications. The ability to quickly create small services that can be individually deployed, configured and scaled, as building blocks for scalable, highly distributed and fault-tolerant systems has been causing every company to rethink on how to architect modern systems and making Spring Boot shine in popularity.

SpringOne Platform 2016 Replay: Spring For Apache Kafka

Recorded at SpringOne Platform 2016.
Speakers: Gary Russell
Slides: http://www.slideshare.net/SpringCentral/spring-for-apache-kafka

With the advent of the Kafka 0.9+ pure Java client, the Spring Team has created the new spring-kafka project with familiar Spring abstractions such as the KafkaTemplate, message listener container and POJO listener annotation @KafkaListener.

In this talk we’ll take a look at the features of the project as well as the new version (2.0) of spring-integration-kafka which is now based on the Spring for Apache Kafka project.

SpringOne Platform 2016 Replay: Spring and Big Data

Recorded at SpringOne Platform 2016.
Speaker: Thomas Risberg
Slides: http://www.slideshare.net/SpringCentral/spring-and-big-data

In this talk we will discuss ways to develop big data pipelines using Spring technologies. Learn how we can stream data into HDFS, run a Spark or a Hive job and extract the results from HDFS or Cassandra for presentation. The solution we develop will be a cloud-native pipeline that we will be able to run both locally and in the cloud.

The presentation focuses around the code for our solution and we also cover how to set up a test environment both locally and in the cloud. While building our solution using Spring Boot and Spring for Apache Hadoop we’ll cover how this app can be integrated in a larger context such as Spring Cloud Stream and Spring Cloud Data Flow. We will also discus configuration solutions for running our app in a variety of environments.

SpringOne Platform 2016 Replay: Building resilient and evolutionary data microservices

Recorded at SpringOne Platform 2016.
Speaker: Vinicius Carvalho
Slides: http://www.slideshare.net/SpringCentral/building-resilient-and-evolutionary-data-microservices

How can we build data pipelines that are resilient to change? Data usually outlives application code, and we have to be prepared to deploy streams that can cope with the evolution of that data that is in motion. This talk will discuss the approach and supporting patterns to write resilient data microservices with Spring Cloud Stream and Spring Cloud Dataflow. We will discuss the role of a centralized Schema repository, and how can we work with different data models and protocols to achieve schema evolution. A centralized schema service will also help us understand what kind of data is currently being served and consumed by the different parts of our distributed system.

Spring for Apache Kafka 1.1.3 available now

It is my pleasure to announce that the Spring for Apache Kafka 1.1.3 maintenance release is available now.

As usual, thanks to the community for any feedback and contribution as always. Looking forward for more!

This release contains several bug fixes, including proper offset commit handling when using a BatchListener; therefore an upgrade is highly recommended.

Right now master has been switched to the version 2.0 for Java 8 and Spring Framework 5.0 code base. We have some plans for high-level API for Kafka Streams and Reactor Kafka support.

Spring Cloud Camden.SR5 is available

On behalf of the team, I am pleased to announce that Service Release 5 of the Spring Cloud Camden Release Train is available today. The release can be found in our Spring Release repository and Maven Central. The documentation can be found here.

Included in this release is the Spring Boot 1.5 compatibility of all the Spring Cloud projects. Other than the addition of Spring Cloud Task, this release includes primarily bug fixes.

NOTE: This release is not compatible with Spring Boot 1.3. In other words your Spring Boot 1.3 application will not work with Camden.SR5.

Cloud Foundry Manifest Editor Beta released for Visual Studio Code

As part of our activities to support developers around the globe building applications with Spring and deploying those apps to Cloud Foundry and PCF, we are proud to announce our first beta version of the Cloud Foundry Manifest editing support for Visual Studio Code (on macOS, Linux x64, and Windows).

Why Visual Studio Code?

Visual Studio Code is a lightweight and open-source code editor that runs on macOS, Linux x64, and Windows. It is based on an interesting architecture with regards to extensibility. Support for languages in Visual Studio Code gets implemented as so called “language servers”. Those language servers are independent of the editor that you use. The editor and the language server are connected using a protocol (called the language server protocol). Even though Visual Studio Code introduced this protocol, other editors and IDEs started to adopt this language server protocol - like the Eclipse IDE (from version 4.7 on) or Eclipse Che as a cloud IDE. Other lightweight editors like Sublime Text and Atom will likely offer support in the near future, too. As a result, we can focus on implementing the Cloud Foundry manifest editor support as an independent language server and you can add this support to the editor or IDE of your choice.
