As the leading full-stack application framework for Java SE and EE, the Spring Framework continues to deliver significant benefits to Java developers, increasing development productivity and runtime performance while improving test coverage and application quality.
In this talk, core Spring Framework committer Sam Brannen will provide attendees an overview of the new features in Spring 3.2 as well as a sneak peak at the roadmap for 4.0.
Spring Framework 3.2 builds on several themes delivered in 3.1 with a continued focus on asynchronous MVC processing with Servlet 3.0, support for using @Autowired and @Value as meta-annotations, support for custom @Bean definition annotations, and early support for JCache 0.5. Regarding the internals, CGLIB 3.0 and ASM 4.0 have been inlined, and the framework is now built with Gradle and hosted on GitHub. For those interested in testing their Spring-based web applications, Spring 3.2 offers new support for loading WebApplicationContexts in the TestContext framework, and the formerly standalone Spring MVC Test project is now included in the spring-test module, allowing for first-class testing of Spring MVC applications.
Gradle is an open source build automation tool that uses Groovy for its build configuration files rather than XML like Maven. It offers features like incremental compilation, parallel task execution, and a built-in dependency management system. Projects can be configured as multi-module builds with hierarchical or flat layouts. Gradle supports plugins for tasks like compilation, testing, packaging, and publishing. It integrates with IDEs like IntelliJ, Eclipse, and NetBeans and can be used to build Java EE applications and other projects.
CDI portable extensions are one of greatest features of Java EE allowing the platform to be extended in a clean and portable way. But allowing extension is just part of the story. CDI opens the door to a whole new eco-system for Java EE, but it’s not the role of the specification to create these extensions.
Apache DeltaSpike is the project that leads this brand new eco-system by providing useful extension modules for CDI applications as well as tools to ease the creation of new ones.
In this session, we’ll start by presenting the DeltaSpike toolbox and show how it helps you to develop for CDI. Then we’ll describe the major extensions included in DeltaSpike, including 'configuration', 'scheduling' and 'data'.
This document provides an overview of CDI (Contexts and Dependency Injection) and some portable CDI extensions, including Apache DeltaSpike. It discusses key CDI concepts like dependency injection, interceptors, events, and scopes. It introduces Apache OpenWebBeans as a fast and stable CDI container implementation. It then demonstrates how DeltaSpike extends CDI with additional features like transaction management, qualifiers, specialized configuration, and alternatives. The document encourages involvement to help shape the future of Apache DeltaSpike.
The document discusses how to grow microservices from a monolithic architecture using a staged approach. It recommends starting with a modular monolith broken into bounded context modules that can be deployed and tested independently. These modules can then be upgraded to independent microservices by separating databases, exposing APIs, and moving to an eventual consistency model. The process should be iterative, allowing code to be refactored and services extracted gradually based on factors like scalability needs and usage patterns. Practical advice includes API-first design, avoiding reusable frameworks, using schema per bounded context, and embracing testing and devops best practices.
The document is a presentation about Node.js that discusses what problem it helps solve, its use of event-driven and non-blocking I/O, common use cases, industry support and examples of usage, how to code in Node.js including modules and frameworks, and how to scale Node.js applications. The presentation was given by Ovidiu Dimulescu at the Jax CodeCamp in October 2012.

Performance of Microservice Frameworks on different JVMsMaarten Smeets
A lot is happening in world of JVMs lately. Oracle changed its support policy roadmap for the Oracle JDK. GraalVM has been open sourced. AdoptOpenJDK provides binaries and is supported by (among others) Azul Systems, IBM and Microsoft. Large software vendors provide their own supported OpenJDK distributions such as Amazon (Coretto), RedHat and SAP. Next to OpenJDK there are also different JVM implementations such as Eclipse OpenJ9, Azul Systems Zing and GraalVM (which allows creation of native images). Other variables include different versions of the JDK used and whether you are running the JDK directly on the OS or within a container. Next to that, JVMs support different garbage collection algorithms which influence your application behavior. There are many options for running your Java application and choosing the right ones matters! Performance is often an important factor to take into consideration when choosing your JVM. How do the different JVMs compare with respect to performance when running different Microservice implementations? Does a specific framework provide best performance on a specific JVM implementation? I've performed elaborate measures of (among other things) start-up times, response times, CPU usage, memory usage, garbage collection behavior for these different JVMs with several different frameworks such as Reactive Spring Boot, regular Spring Boot, MicroProfile, Quarkus, Vert.x, Akka. During this presentation I will describe the test setup used and will show you some remarkable differences between the different JVM implementations and Microservice frameworks. Also differences between running a JAR or a native image are shown and the effects of running inside a container. This will help choosing the JVM with the right characteristics for your specific use-case!

15. OpenShift Power: What's Power?
• OpenShift Power can deploy applications to the cloud that are
written to Linux (i.e. written in C, or using many binary
components) and anything that builds on Linux.
• Ultimate flexibility and access at the operating system
configuration level
• Power can deploy applications which have no web front-end
• Power has an image configuration system, a scripting template
system, an image library for re-using template
16. OpenShift Express

18. OpenShift Pricing
OpenShift Express OpenShift Flex
Pricing Free and it is intended to Free to use (during developer
remain free in future also preview), but will incur additional
charges from service provider
(AWS)
The pricing is still not decide
Small: 32 BIT, 1 CORE(S), 1.66 GB
Instance cost: 62$ (0.085$ per hour)
DISK SIZE: 10GB
* OpenShift Power pricing will be announced once they release the offering
19. Limitations of OpenShift
• OpenShift Express and Flex are only available in developer preview
today
• There is no SLA or support
• Express preview supports one application per user
• OpenShift Express is accessed from command line client tools, no web
interface
• The ability to install OpenShift on your own servers is not yet supported.
Stay tuned for news of the opensource announcement!
• It is not cloud agnostic and only works with "approved" clouds (EC2)
• It doesn’t support .Net framework and Windows
20. Strengths of OpenShift
• First Java EE 6 implementation in a PaaS model, OpenShift delivers a simple way
for developers to build and deploy Java in the cloud.
• This is PAAS 2.0, It’s open choice of frameworks. It’s open choice of clouds and
it’s open choice of middleware. Open, open, open
• It will be open sourced, supports multiple languages and frameworks, and support
multiple clouds, with AWS being the first cloud supported
• No customer is locked into a cloud platform
• OpenShift Express is completely free, making it easier to drive trials and adoption
• OpenShift supports your Tools
• Shell Access
• It supports both new as well as existing applications
21. OpenShift Q&A
• Q: Can I deploy Maven + (Spring + Hibernate) Annotation + MySQL + REST?
• YES, Easily - all of this does work. PLAY WITH IT FOR FREE!
• Q: Sticky sessions?
• Flex does supports sticky sessions and multi-instance scaling. Express
doesn't have multi-instance scaling yet so it's not needed there currently.
• Q: Access to DB from outside?
• In Express it is not supported but you can use phpMyAdmin. In Flex, you have
your own instance and a public IP so you can access remotely.
• Q: Remote debugging…?
• OpenShift don't allow arbitrary binding of ports on the externally accessible IP
address. Port restriction is definitely something on their roadmap though.
22. OpenShift Q&A
• Q: Quota limits?
• 512MB block storage / 40000 files, Processes – 250, Threads - unlimited as long as in the
constraints of the other limits, Resident Memory - 300MB, Swap - 100MB
• Java memory at 128Mb of max heap, and 83Mb of permgen, so your applications need to
fit within that constraint
• Q: Save/Upload files to the file system (Express) supported?
• Yes - best practice is to use the $OPENSHIFT_DATA_DIR environment variable for a
persistent data location
• Q: Are any of Amazon services available OOTB?
• When Flex is running applications in Amazon, it takes advantage of features like the
elastic load balancer for clustering. Integration with Amazon Relational Database Service
(Amazon RDS) exists as well
• Q: Database scaling for MySQL and MongoDB?
• Sort of depends. MySQL is offered in both Express and Flex but there isn't automatic
master -> master or master -> slave scaling yet. MongoDB is in Flex and does support
replica set configuration. Replica sizes don't adjust automatically though.
23. OpenShift Q&A
• Q: Can I utilize Ant?
• You can embed ant in the pom.xml - just keep the OpenShift profile in the
pom.xml
• Q: Maven Plugin?
• They use stock Maven with the profile to specify deployment locations so no
maven plugins needed. Eclipse plugin from JBoss Tools is the answer.
• Q: Search engine? They added it to the backlog …
• Q: Can I point my own domain name at OpenShift Express hosted
application?
• “It is not currently possible... in the roadmap“
• Lack of information about MRG within OpenShift: They will try to find
something and post in the blog

Компания Red Hat представила предварительный выпуск проекта OpenShift, в рамках которого развивается специально оптимизированное для разработчиков открытого ПО PaaS-решение (платформа как сервис), предназначенное для выполнения конечных приложений в облачных окружениях (для сравнения, IaaS-платформы обеспечивают запуск образов готовых операционных систем). Платформа предоставляет разработчикам возможность запуска приложенийи свободу выбора, написанных на языках Java, Python, PHP и Ruby, с использованием фреймворков JBoss, Spring, Seam, Weld, CDI, Rails, Rack, Symfony, Zend Framework, Twisted, Django и Java EE. Из баз данных поддерживаются MySQL, EnterpriseDB (PostgreSQL), Couchbase, и MongoDB.
Red Hat Summit 2011 in BostonСистема основана на разработках компании Makara, купленной Red Hat в ноябре прошлого года. Некоторые компоненты OpenShift пока остаются закрытыми, но со временем платформа будет полностью переведена в разряд продуктов с открытым исходным кодом. По своим функциям OpenShift напоминает открытую в прошлом месяце PaaS-платформу VMware Cloud Foundry, которая пока поддерживает запуск приложений на языках Java и Ruby. Из других существующих PaaS-платформ можно отметить Zend PHP Solution Pack, Google App Engine и Windows Azure, недостатками которых является недостаточная универсальность и необходимость использования специального API.По словам Исаака Рота (Isaac Roth) — руководителя направления PaaS в Red Hat, платформа OpenShift будет готова к середине 2012 года.
The OpenShift deployment model currently offers three user levels:OpenShift ExpressOpenShift FlexOpenShift Power (Coming soon)OpenShift предоставляет три сервиса
Power - позволяет размещать в cloud-окружениях любые приложения, работающие в Linux, включая приложения на языке Си и программы, содержащие бинарные компоненты и не привязанные к web-технологиям (например, клиент-серверные приложения, торговые системы, системы моделирования и т.п.). Архитектура рабочего окружения может быть сформирована самостоятельно, при этом пользователю предоставляется низкоуровневый доступ к конфигурации рабочего окружения на уровне операционной системы. Среди доступных пользователю функций: настройка содержимого образа виртуального окружения, система шаблонов, библиотека типовых образов и возможности по динамической генерации образов, в зависимости от типа используемой системы виртуализации.
Express - позволяет организовать выполнение приложений на языках Java,PHP, Ruby и Python. Окружение рассчитано на перенос уже разработанных приложений и позволяет запустить проекты такого уровня, как Drupal и MediaWiki. Управление производится через набор работающих в режиме командной строки утилит. всё, что вы делаете локально при создании и компиляции приложения, а именно загрузку библиотек из репозитария, разрешение зависимостей для этих библиотек, компиляцию кода, сборку приложения, и, наконец, развертывание WAR-файлов на рабочих серверах – всё это сделает за вас OpenShift автомагически.Запуск приложения сводится к регистрации аккаунта, установки пакета rhc (доступен в форматах deb и rpm), созданию rhc-домена (rhc-create-domain -n имя), регистрации в нем приложения (rhc-create-app -n phpapp -t php-5.3.2) и установки приложения (git commit -a; git push)
Flex - позволяет организовать работу в окружениях, запущенных на стороне сертифицированных провайдеров облачных окружений (например, Amazon EC2), т.е. Flex предоставляет возможность автоматизации запуска приложений в IaaS-системах, беря на себя заботы по формированию образа операционной системы. В отличие от варианта Express, управление во Flex производится через графический интерфейс пользователя, в котором реализованы функции создания, развертывания, конфигурирования, помощи в миграции и мониторинга. Поддерживаются языки PHP и Java (JBoss, Java EE6), web-сервер Apache, серверы приложений JBoss AS, Tomcat, базы данных MySQL, MongoDB и Memcached.
Once you have this the workflow for OpenShift is as simple as Write Code, commit and push - go back to writingcode…And to make this less abstract then let me just show you how simple it actually is.
OpenShift Express Here's a recap of the rest of exciting features announced this month. Eclipse IDE integration via JBoss Tools: Let the cloud come to you! OpenShift is now integrated with Eclipse via JBoss Tools. Grant has a nice step-by-step blog and a video that shows you how easy it is. Continuous Integration Service via Jenkins: In our journey to provide you with a platform that covers the entire application development life cycle management (ADLM) we just added continuous integration in OpenShift with support for Jenkins. Check out Mike's technical overview blog or David Blado's how-to blog and video learn more. Totally Web-based Application Setup: As an alternative to the command line, it is now possible to setup your OpenShift Express applications in seconds from the web-based OpenShift control panel. Graphical Administration Console for Relational DBs: As it was previously detailed in David's blog, OpenShift Express now provides a phpMyAdmin web console for managing you MySQL instances on OpenShift. Want to see the latest and greatest OpenShift features in action? Then register for our webinar on Nov. 21st with Mark Little, Max Andersen and myself.--------------------------What's New in OpenShift Flex Cost Visibility and Budget Control Do you want to get a handle on your AWS charges when using dedicated servers on OpenShift? Would you like to see what you've consumed and also get a projection on how much you may consume the rest of the month? Do you want to set a budget for the month and periodically track spending against your budget? Look no further, OpenShift Flex now has this functionality built into the UI. Zend Server: One of the most popular ways to get Enterprise-grade features in you PHP application is by using Zend Server as an application container. Your unmodified PHP/Zend Server application can run now in OpenShift with support for version 5.5. Support for MongoDB 2.0Three powerful MongoDB features have been included in this release: We've upgraded the cartridge to the latest and greatest 2.0 version. We've also made MongoDB configuration parameters accesible in the OpenShift console. And finally, the convenience and power of MongoDB logs has been integrated into the OpenShift dashboard.
