SpringOne2GX 2014 Replay: Experiences using Grails in a Microservice Architecture

Essential Grails Track

Slides: http://www.slideshare.net/SpringCentral/experiences-using-grails-in-a-microservice-architecture-spring-one2gx2014-41177964

For some web applications it does not make sense to have 1 monolithing process which handles all of the requirements of the application. More and more often Grails is showing up in microservice architectures where instead of building 1 monolithing web application which is responsible for all of the pieces of the application puzzle, microservice applications are being assembled which collectively solve the requirements of the larger application. Grails is very well suited for this type of architecture. A microservice based architecture can result in applications which are easier to build, easier to test, easier to extend and are easier to adapt to changing business requirements.

SpringOne2GX 2014 Replay: Android and Groovy, a winning pair?

More Groovy Track

Slides: http://www.slideshare.net/SpringCentral/groovy-android-41263570

For 10 years, Groovy has dramatically improved the productivity of Java developers on the desktop. With unique like closures, builders, AST transformations, traits, optional static compilation and many more, Groovy turned out to be a very competitive language on the JVM. Compared to other JVM languages, Groovy has the major advantage of being totally Java-friendly, both in terms of syntax and interperability. But during those years, what happened on the mobile world? In particular, Android developers are used to develop applications in Java, so why Groovy, a JVM language, wouldn't be usable for Android development too? Can we ease the pain of Android developers too?

SpringOne2GX 2014 Replay: Painless Build and Deploy for YARN Applications with Spring

Recorded at SpringOne2GX 2014. Speaker: Janne Valkealahti Slides: http://www.slideshare.net/SpringCentral/spring-one2gx-2014springyarn Big Data Track Spring's goal, like any good framework, has always been to handle the infrastructure so you can focus on your application code. Join this session to see how Spring provides a simple programming model to develop applications than can easily be tested and deployed as either a YARN application or a traditional application. No longer will you need to struggle with 3rd party library build and packaging issues, XML, and how the YARN Appmasters…

Webinar Replay: Using Reactor for Asynch/non-blocking Microservices

News | Pieter Humphrey | December 11, 2014 | ...

Speaker: Stephane Maldini


What is the role of asynchronous, non-blocking style-communication in microservices? Join Stephane Maldini for a revealing look at why reactive components are so important in an eventually-consistent approach like microservice architecture. When services own their data and are completely independent, having a (reactive) abstraction layer can perform a variety of roles. Being able to parallelize resources a microservice owns is an important technique. Another might be as an event bus, pulling state data from various micro services dynamically, checking against the cached, fairly up-to-date local copy. While a microservice has “all” the data it needs from other services to respond to a request, this data is not necessarily up-to-date—an important constraint to be prepared to accept. Stephane will also discuss other async use cases outside of microservices and how www.reactive-streams.org protocol support allows levels of portability across vendor implementations.

Spring XD - A Guided Tour

Recorded at SpringOne2GX 2014.

Speakers: Patrick Peralta, David Turanski

Big Data Track

Slides: http://www.slideshare.net/SpringCentral/spring-xd-guided-tour

What happens when a Stream is deployed to a Spring XD cluster? How does Stream processing and data partitioning work? How does the cluster recover when a Spring XD container goes down? How does Spring XD create and manage application contexts? What is a Plugin? How does Spring XD support extensibility? Our experienced guides will take you on a tour of the Spring XD runtime environment, navigating Streams and observing how Modules thrive in their natural habitat. We will explore the role of ZooKeeper, Spring Integration, and Spring Boot through beautiful panoramas, code samples, and daring demonstrations.

SpringOne2GX 2014 Replay: Implementing the Lambda Architecture with Spring XD

News | Pieter Humphrey | December 09, 2014 | ...

Big Data Track

The lambda architecture has been proposed as a general purpose data system that aims to solve the problem of computing arbitrary functions on an arbitrary dataset in (near) real-time. In this talk we introduce the lambda architecture and show how it can be implemented with SpringXD, GemFireXD and Hadoop (HDFS and MapReduce) as the foundation of the architecture implementation. To validate the architecture we introduce a CDR (Call Detail Record) mining application as use case of the lambda architecture. We finalise by showing a demo of the CDR (Call Detail Record) mining application.

SpringOne2GX 2014 Replay: Spring XD for Real-time Hadoop Workload Analysis

News | Pieter Humphrey | December 09, 2014 | ...

Recorded at SpringOne2GX 2014.

Speakers: Vineet Goel, Girish Lingappa, Rodrigo Meneses

Slides: http://www.slideshare.net/SpringCentral/spring-one2gx-2014springxdhadoopworkloadanalysis

Big Data Track

As Hadoop goes mainstream in enterprise big data deployments, IT organizations expect and demand enhanced operational management of their Hadoop clusters in production. Admins require more than just cluster health monitoring; they need the ability to do real time workload analysis for performance tuning and troubleshooting. Real-time log analysis of jobs at a user or application level can allow admins to manage and tune workloads better, especially in multi-tenancy Hadoop cluster services. Join us to learn how Pivotal team leveraged Spring XD data ingestion and batch processing framework, GemFire XD & other components to solve this interesting challenge on a large 1000-node (Analytics Workbench) cluster. Using Spring XD to ingest YARN service and MapReduce application logs through a real-time data pipeline into HDFS, the team leveraged familiar SQL-based queries to analyze fine-grained cluster utilization.

SpringOne2GX 2014 Replay: Develop powerful Big Data Applications easily with Spring XD

News | Pieter Humphrey | December 09, 2014 | ...

Recorded at SpringOne2GX 2014.

Speakers: Mark Fisher and Mark Pollack

Slides: http://www.slideshare.net/SpringCentral/develop-powerful-big-data-applications-easily-with-springxd

Big Data Track

Spring XD aims to provide a one stop shop for writing and deploying Big Data Applications. It provides a scalable, fault tolerant, distributed runtime for Data Ingestion, Analytics, and Workflow Orchestration using a single programming, configuration and extensibility model. By not requiring developers to rationalize all of this themselves across the many different solutions available today, Spring XD greatly reduces the inherent complexity of Big Data development. It's all built on proven projects like Spring Integration, and Spring Batch. You'll see for yourself how this heritage combines to provide a scalable runtime environment, that is easily configured and assembled via a simple DSL.

Security for Microservices with Spring and OAuth2

Recorded at SpringOne2GX 2014.

Speaker: Dr. David Syer

Slides: http://www.slideshare.net/SpringCentral/syer-microservicesecurity

OAuth2 is a lightweight security protocol that is well-suited for use with HTTP, the protocol at the heart of many modern architectures. Spring Security OAuth2 has a load of new features, not the least of which being the `@Configuration` support in version 2.0. Combine these with Spring Boot and you have a platform which can get you a secure HTTP service application in about 20 lines of code. This presentation shows how the combination of rapid development and production-ready features in the modern Spring stack are a perfect mixture for developing secure components in a system composed of microservices. We explore the new features in Spring OAuth2, guide you through the choice of which to use and when, and show how easy they are to enable quickly. This is the 90 minute version of the same talk that was on the Spring webinar program recently.
