SpringOne Platform 2016 Replay: Putting a SpEL on Spinnaker: Evolving an Expression Language for Continuous Delivery

Recorded at SpringOne Platform 2016.
Speaker: Tomas Lin, Netflix
Slides: http://www.slideshare.net/SpringCentral/putting-a-spel-on-spinnaker-evolving-an-expression-language-for-continuous-delivery-at-netflix

Spinnaker is an open source, multi-cloud continuous delivery platform. It is used by over 90% of cloud deployments at Netflix. The Spring Expression Language (SpEL) is heavily leveraged to fully articulate and extend Spinnaker’s automated deployment pipelines. SpEL is used heavily to interact with pipeline stages and triggers for variable substitution, information retrieval and conditional evaluation. This session will walk through the evolution of Spinnaker’s use of SpEL over two years of active development. We will share the code, features and wisdom gained from helping the Netflix and open source community adopt SpEL. You should attend if you are interested in the Spinnaker platform and the continuous delivery pipelines feature, or wish to learn how to fully harness SpEL for your own tools.

SpringOne Platform 2016 Replay: Implementing Config Server and extending it

Recorded at SpringOne Platform 2016.
Speaker: Clint Checketts, Domo.com
Slides: http://www.slideshare.net/SpringCentral/implementing-config-server-and-extending-it

Spring Cloud Config Server is a great tool for getting your application configuration under source control. We’ll start with the quick overview of Spring’s Environment and properties and how config server enhances those, while keeping the same model.

Next we’ll discuss what concerns you need to take into account when rolling out config server like security, encryption, and location of your repositories (if using Git).

SpringOne Platform 2016 Replay: An Introduction to Distributed Tracing and Zipkin

Recorded at SpringOne Platform 2016.
Slides: http://www.slideshare.net/SpringCentral/how-to-properly-blame-things-for-causing-latency

Latency analysis is the act of blaming components for causing user perceptible delay. In today’s world of microservices, this can be tricky as requests can fan out across polyglot components and even data-centers. In many cases, the root source of latency isn’t a component, but rather a link between components.

This session will overview how to debug latency problems, using call graphs created by Zipkin. We’ll use trace zipkin itself, setting up from scratch using docker. While we’re at it, we’ll discuss how the model works, and how to safely trace production. Finally, we’ll overview the ecosystem, including tools to trace ruby, c#, java and spring boot apps.

SpringOne Platform 2016 Replay: Implementing Microservices tracing with Spring Cloud and Zipkin

Recorded at SpringOne Platform 2016.
Speakers: Marcin Grzejszczak, Reshmi Krishna
Slides: http://www.slideshare.net/SpringCentral/implementing-microservices-tracing-with-spring-cloud-and-zipkin

2015 was the year of microservices. It’s already common knowledge that creating distributed systems is not easy. It’s 2016 and it’s time to show how that complexity can be contained.

Service Discovery and Registry (Zookeeper / Consul / Eureka), easy request sending with client side load balancing (Feign + Ribbon), request proxying with Zuul. Everything is easy with Spring Cloud. Just add a dependency, a couple of lines of configuration and you’re ready to go.

SpringOne Platform 2016 Replay: Developing microservices with aggregates

Recorded at SpringOne Platform 2016.
Speaker: Chris Richardson
Slides: http://www.slideshare.net/SpringCentral/developing-microservices-with-aggregates

The Domain Model pattern is a great way to develop complex business logic.
Unfortunately, a typical domain model is a tangled, birds nest of classes.
It can’t be decomposed into microservices.
Moreover, business logic often relies on ACID transactions to maintain consistency.
Fortunately, there is a solution to this problem: aggregates.
An aggregate is an often overlooked modeling concept from the must read book Domain Driven Design.
In this talk you will learn how aggregates enable you to develop business logic for the modern world of microservices and NoSQL.

SpringOne Platform 2016 Replay: Spring Boot at PayPal

Recorded at SpringOne Platform 2016.
Speakers: Fabio Carvalho, Eduardo Solis
Slides: http://www.slideshare.net/SpringCentral/spring-boot-paypal

Although PayPal has been using Spring in production for many years, as part of a goal to move towards micro-services, PayPal recently introduced Spring Boot to its Java framework (known as “Raptor”), which includes RESTful services, Batch and Message Daemon applications. Besides Spring Boot, other Spring projects are used, such as Spring framework, Spring Batch and Spring Integration.

Spring Integration Extension for Hazelcast 1.0.0 M2 Available

On behalf of the Spring Integration community I’d like to announce the second Milestone of Spring Integration Extension for Hazelcast and its artifact is spring-integration-hazelcast.1.0.0.M2, which is available in the Milestone Repository.

The project has been around for some time and there has not been so much activity since the previous Milestone 1 and it only recently gained enough community traction to warrant a release. So, first of all, big thanks to you, the community, for your contributions!

Spring LDAP 2.3.1 Released

On behalf of the community, I’m pleased to announce the release of Spring LDAP 2.3.1!

This release brings in a new era for Spring Data compatibility. Integration for Spring LDAP and Spring Data has been moved to spring-data-ldap so that it can partake in the Spring Data release train and ensure compatibility with the latest and greatest Spring Data code base.

The release also brings read only attribute support.

Note
We did an immediate release of Spring LDAP 2.3.1 due to an issue with the Spring LDAP 2.3.0 release.

Spring Cloud Stream Brooklyn.SR2 and Chelsea.M1 released

On behalf of the community, I am happy to announce the release of Spring Cloud Stream Brooklyn.SR2 and Chelsea.M1 release trains. As part of the next installment to Brooklyn release train, Brooklyn.SR2 adds a number of new features and fixes. The next release train Chelsea.M1 builds on top of Spring Boot 1.5 and a contains a core improvement listed below.

What is new?

A few highlights of the improved areas:

  • Schema Registry Support: fixed issues related to using the Schema Registry server, in particular support for MySQL and Postgresql;
  • Aggregate Applications: improved support for property propagation via namespaces;
  • Reactive support: Aligns declarative (e.g. reactive) handler support with imperative mode, which makes it easier to seamlessly adopt a functional programming model. In particular, this adds support for the following idiom:
