The document discusses developing microservices with WildFly Swarm and deploying them on OpenShift. It covers how WildFly Swarm allows Java EE components to be packaged independently as microservices. It also explains how OpenShift provides the prerequisites for managing microservices like automated deployment, service discovery, and containers. The key takeaways are that Java EE is still relevant through projects like WildFly Swarm, which enable microservices, and that OpenShift's PaaS capabilities complement a microservices architecture.

Navigating the Container Orchestration Maze

Alex Vranceanu

With Docker adoption on the rise in many organisations, it’s becoming increasingly challenging to manage multiple containerized environments across clusters and infrastructure providers. Starting from the question of what do we use to manage our Kubernetes clusters in cloud or on-premise, we’ll look at a head-to-head comparison of major Container Orchestration and Management platforms in the enterprise and open-source world. RedHat OpenShift Container Platform, Docker Enterprise, DC/OS, Rancher and Spinnaker and the main platforms which we’ll be taking a closer look at and I hope that this comparison will help make a more informed choice for a Container Management platform. Looking forward to discussing the above and possibly other options with you. For those interested after the presentation, we could have a hands-on session with all of the above platforms, to get a real feeling of each one.

Putting The 'M' In MBaaS—Red Hat Mobile Client Development Platform (Jay Balu...

Red Hat Developers

When you hear the term "MBaaS," or "Red Hat Mobile," there is usually a lot of discussion about powerful scaling, back-end integrations, hosting options, containerization, etc. However, we can't forget what that "M" stands for, and why the platforms exist in the first place, which is to develop and deliver top-notch mobile applications to your users. In this session, we'll review what makes all of this possible—client SDKs, hybrid solutions like Cordova, and Xamarin, and our own Build Farm and Unified Push server. Not stopping there, our AppForms support makes it a snap to tie in back-end systems all the way to your app. And this is all backed by various templates, guides, and new open source resources that will help you get started and join the fun.

My introduction slides from Build a Cloud Day Paris, the full recap of the event is available at http://buildacloud.org/blog/269-a-recap-from-bacd-paris.html. We had over 70 people attend this event where users of cloudstack, integrators and ecosystem partners presented how they work with cloudstack. iKoula a service provider in Paris showed how they created a cloud offering, Usharesoft showed how the can enhance image management and publish templates in cloudstack, Apalia showed how they have deployed cloudstack in multiple enterprises. Amysta showed how their products gives you very detailed billing information for your cloud. INRIA presented their private cloud for a continuous integration platform for France research community and btrcloud showed how they developed a plugin to provide adanced VM scheduling in your datacenter. All presentations showed the various components of a cloud infrastructure. In these slides I also show how the Apache Software Foundation can be the base of your cloud and big data infrastructure since all components are under the ASF: CloudStack, hadoop, libcloud, jclouds, whirr, Stratos, Storm etc...

Writing Java EE microservices using WildFly Swarm

Comsysto Reply GmbH

Check out the talk to the slides: http://bit.ly/1ReY8uJ Talk Abstract: Using Swarm, you can select “just enough app server” to support each of your microservices. In this session, we’ll outline how WildFly Swarm works and get you started writing your first microservices using Java EE technologies you’re already familiar with. You’ll learn how to setup your build system (Maven, Gradle, or your IDE of choice) to run and test WildFly Swarm-based services and produce runnable jars. We will walk from the simple case of wrapping a normal WAR application to the more advanced case of configuring the container using your own main(…) method.

Neo4j for Cloud Management at Scale

Neo4j

Cloud system configurations and their dependencies can quickly grow into the thousands of virtual machine, network and storage components. Once software is included, the number of components can easily rise into six figures. Frequent releases using continuous integration and deployment tools makes a repository of these components and relationships absolutely critical to cloud system integrity and quality of service no matter what cloud management tools you use. Systems configurations are more naturally represented using a graph database than the relational representations used by traditional IT management products. Our talk will explore how we use Neo4J to create a live, active, self-updating repository service, containing nearly all virtual hardware, network and software components and their dependencies, enabling continuous deployment in any cloud environment at scale.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

1. October 4, 2016 | Jakarta

2. DEVELOPING MICROSERVICES WITH WILDFLY SWARM AND DEPLOYING ON OPENSHIFT Eryan Ariobowo Solutions Architect

3. Partner Technology Update3 AGENDA • The Context: Microservices and Java EE • WildFly Swarm: Concepts, Ideas & Mechanics • Microservices on OpenShift

4. Partner Technology Update4 MONOLITH Business Logic CDI REST TX Database JPA UI HTML DBLoad Balancer

5. Partner Technology Update5 MONOLITH DISADVANTAGES • Large and complex • Difficult to maintain • Obstacles to frequent deployments • Makes adoption of new technologies difficult

6. Partner Technology Update6 MICROSERVICES Service DB Load Balancer JAR DB DB Service JAR Service JAR Service JAR

7. Partner Technology Update7 MICROSERVICES ADVANTAGES • Better alignment with organisation • Starts faster, speeds up deployments • Fault isolation • Services can be scaled independently • Local changes can be deployed easily • Flexible choice of technology

8. Partner Technology Update8 WHAT ARE MICROSERVICES? “…an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API.” Martin Fowler

9. Partner Technology Update9 MONOLITH VS MICROSERVICES

10. Partner Technology Update10 PERCEPTIONS ON JAVA EE Likes • Robust and mature components • Scalable, standards compliant, integrates well Dislikes • Monolith and heavyweight

11. Partner Technology Update11 MICROSERVICE REQUIREMENTS • Transaction • REST stack • Persistence and connection pooling • Async messaging • Caching • Authentication & authorisation Typically provided by App Containers

12. Partner Technology Update12 WILDFLY SWARM • OSS Project sponsored by Red Hat • Sidekick of Wildfly Application Server • Allows Java EE components to become independently deployable services • Build applications as fat jars

13. Partner Technology Update13 JUST ENOUGH APP SERVER • Use the API’s you want • Include the capabilities you need • Wrap it up for deployment

14. Partner Technology Update14 FRACTIONS

15. Partner Technology Update15 UBERJAR • A single .jar file containing your application, • the portions of WildFly required to support it, • an internal Maven repository of dependencies, • plus a shim to bootstrap it all

16. Partner Technology Update16 MICROSERVICE PREREQUISITES • Automated deployment and testing • Rapid provisioning • Service discovery • Monitoring • Containers • Load balancing • Throttling • Circuit breaker PaaS
