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…

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).

Finally we…

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…

Recorded at SpringOne Platform 2016. Speakers: - Ben Hale, Paul Harris, Stephane Maldini Slides: http://www.slideshare.net/SpringCentral/designing-implementing-and-using-reactive-apis

The Java community is on the cusp of a major change in programming model. As the industry moves towards high-performance micro-service architectures, the need for a reactive programming model becomes clear. In this session, the lead developers of the Cloud Foundry Java Client will talk about what led them to choose a reactive API. Using that project as a lens, they'll explore how they designed and implemented…

Recorded at SpringOne Platform 2016 Speakers: Ray Tsang, Bret McGowen, Google Slides: http://www.slideshare.net/SpringCentral/grpc-101-for-spring-developers gRPC is a high performance, open source, general RPC framework that puts mobile and HTTP/2 first. gRPC is based on many years of Google's experience in building distributed systems - it is designed to be low latency, bandwidth and CPU efficient, to create massively distributed systems that span data centers, as well as power mobile apps, real-time communications, IoT devices and APIs. It's also interoperable between multiple languages.

Recorded at SpringOne Platform 2016. Speakers: Noriaki Tatsumi, Capital One Slides: http://www.slideshare.net/SpringCentral/operating-a-high-velocity-large-organization-with-spring-cloud-microservices

Releases are hard for many large organizations with complex systems. Challenges like manual processes, change approvals, compliances, legacy systems, varying deployment targets, and scheduled downtimes prevent companies from releasing fast and frequently. Many of us know that when Continuous Delivery is embraced and microservices architecture is done right, those challenges can become things of…

Recorded at SpringOne Platform 2016. Speakers: Sebastien Deleuze, Stephane Maldini Slides: http://www.slideshare.net/SpringCentral/a-lite-rx-api-for-the-jvm

RxJava is a fully fledged and widely used solution to develop Reactive applications, but some interesting alternatives exist. After an overview of the main Reactive APIs available and of Spring Boot Reactive support, this workshop introduces how to develop Reactive applications using Reactor Core 2.5-a powerful and fast alternative. We will learn how to use Flux (N values) and Mono (single value) types with various exercises. This new…

Recorded at SpringOne Platform 2016. Speaker: Stéphane Maldini Slides: http://www.slideshare.net/SpringCentral/reactor-30-a-jvm-foundation-for-java-8-and-reactive-streams

The apparent simplicity of the publisher/subscriber model as exposed in Reactive-Streams can be deceiving. The relatively fast release cycle for libraries in that space is not a myth, concurrency is hard. To keep out undesired side-effects, most Reactive projects have adopted a vertical approach potentially excluding developers from decision-making around execution model or sometimes language.

What if we were able to leave…

Recorded at SpringOne Platform 2016. Speaker: Spencer Gibb Slides: http://www.slideshare.net/SpringCentral/spring-cloud-with-consul-and-vault

Historically it is difficult to store and configure secrets within applications. In the new age of microservices, it is also a challenge to register instances for discovery. Fortunately, Consul and Vault make securing secrets a breeze. Consul's Service Registration mechanism makes easy work of service discovery. When combined with Spring Boot's auto configuration we can leverage Consul and Vault by simply updating our classpath.

In this session we will…
