SpringOne Platform 2016 Replay: Spring MVC 4 Web Apps

Recorded at SpringOne Platform 2016.
Speaker: Rossen Stoyanchev
Slides: http://www.slideshare.net/SpringCentral/spring-mvc-4-web-apps

Spring Framework 4.3 is the last in the 4.x generation and it brings plenty of refinements to the @MVC programming model. In Spring Framework 5.0 the same programming model will be supported on a new reactive foundation. This talk will review the main features in 4.x and preview the work towards Spring Framework 5.0.

SpringOne Platform 2016 Replay: Cloud Native Java with Spring Cloud Services

Recorded at SpringOne Platform 2016.
Speakers: Craig Walls; Spring Social Lead, Pivotal. Roy Clarkson; Spring Mobile Lead, Pivotal.
Slides: http://www.slideshare.net/Pivotal/cloud-native-java-with-spring-cloud-services-64888067

Developing cloud native applications presents several challenges. How do microservices discover each other? How do you configure them? How can you make them resilient to failure? How can you monitor the health of each microservice?

Spring Cloud addresses all of these concerns. Even so, you still must explicitly develop your own discovery server, configuration server, and circuit breaker dashboard for monitoring the circuit breakers in each microservice.

Webinar: Data Microservices in the Cloud

Speakers: Mark Pollack, Mark Fisher
Spring Cloud Data Flow enables you to create data pipelines for many common use-cases such as data ingestion, real-time analytics and data import/export.
In this webinar, we will introduce Spring Cloud Data Flow’s architecture and walk through the orchestration capabilities of long-running and short-lived data-centric applications on multiple runtime platforms such as Cloud Foundry, Kubernetes, Apache Mesos and Apache YARN.
Spring Cloud Data Flow represents the evolution of Spring XD and retains the DSL to define data pipelines as well as the web based UI designer, but changes the component model from modules that used to run inside a container to standard Spring Boot applications built with Spring Cloud Stream and Spring Cloud Task APIs.

SpringOne Platform 2016 Replay: 12 Factor, or Cloud Native Apps: What EXACTLY Does that Mean for Spring Developers?

Recorded at SpringOne Platform 2016.
Speaker: Thomas Gamble, Home Depot
Slides: http://www.slideshare.net/Pivotal/12-factor-or-cloud-native-apps-what-exactly-does-that-mean-for-spring-developers-64853692

Your team is excited about getting started with Spring Boot and Cloud Native, but you’re not entirely sure you’re ready to have the team continuously delivering to prod using cf push from their local desktops. The freedom of cloud native development can be very empowering for developers, but it shouldn’t be something that terrifies the operations and security teams. We’ll discuss how you can setup a fast and reliable deployment process, as well as some interesting things to thing about in the future. One of the most well known descriptions of these new paradigms is the Twelve Factor App (12factor.net), which describes elements of cloud native applications. Many of these needs are squarely met through the Spring Framework, others require support from other systems. In this session we will examine each of the twelve factors and present how Spring, and platforms such as Cloud Foundry satisfy them, and in some cases we’ll even suggest that responsibility should shift from Spring to platforms. At the conclusion you will understand what is needed for cloud‐native applications, why and how to deliver on those requirements.

SpringOne Platform 2016 Replay: Cloud Native Java

Recorded at SpringOne Platform 2016.
Slides: http://www.slideshare.net/SpringCentral/cloud-native-java

"It is not necessary to change. Survival is not mandatory.” -W. Edwards Deming

Work takes time to flow through an organization and ultimately be deployed to production where it captures value. It’s critical to reduce time-to-production. Software - for many organizations and industries - is a competitive advantage. Organizations break their larger software ambitions into smaller, independently deployable, feature -centric batches of work - microservices. In order to reduce the round-trip between stations of work, organizations collapse or consolidate as much of them as possible and automate the rest; developers and operations beget “devops,” cloud-based services and platforms (like Cloud Foundry) automate operations work and break down the need for ITIL tickets and change management boards. But velocity, for velocity’s sake, is dangerous. Microservices invite architectural complexity that few are prepared to address. In this talk, we’ll look at how high performance organizations like Ticketmaster, Alibaba, and Netflix make short work of that complexity with Spring Boot and Spring Cloud.

SpringOne Platform 2016 Replay: Modern Java Component Design with Spring Framework 4.3

Recorded at SpringOne Platform 2016.
Speaker: Jüergen Hoeller
Slides: http://www.slideshare.net/SpringCentral/modern-java-component-design-with-spring-framework-43

Spring’s programming and configuration model has a strong design philosophy with respect to application components and configuration artifacts. Spring’s annotation-based component story is fine-tuned for source code readability as well as consistency across an entire application’s codebase. This session presents selected Spring Framework 4 component model highlights, with a focus on the current Spring Framework 4.3 and a selection of Java 8 enabled features, illustrated with many code examples and noteworthy design considerations.

Webinar Replay: Introducing Spring Cloud Task

Speaker: Michael Minella, Pivotal
One of the major promises of the cloud is that of flexibility. Today, most applications deployed to the cloud are long running processes that use the flexibility of cloud scaling. But computing is full of short lived tasks that start up, do their work, and then terminate. These tasks are excellent cloud use cases since resources can quickly be provisioned - and reclaimed.

In this webinar, we’ll explore a new project in the Spring Cloud portfolio, Spring Cloud Task, a new framework for developing and orchestrating short-lived microservices. We’ll explore various use cases, build your first task, and discuss how to orchestrate tasks using various techniques. Finally, we’ll peek into the roadmap for the Spring Cloud Task project.

Webinar: Understanding microservice latency: An introduction to Distributed Tracing and Zipkin

Speakers: Adrian Cole & Marcin Grzejszczak, Pivotal

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.
