Securing applications and services is no longer just about assigning a username and password. You need to manage identities. You need to integrate with legacy and external authentication systems to provide features that are in demand like social logins and single sign-on (SSO). Your list of other requirements may be long. But you don’t want to develop all of this yourself, nor should you.

Join us for the next online DevNation Live on Thursday, July 19th at 12pm EDT for Container pipeline master: Continuous integration + continuous delivery with Jenkins, presented by Red Hat principal technical product marketing manager for Red Hat OpenShift, Siamak Sadeghianfar.
In this session, we’ll take a detailed look into how you can build a super slick, automated continuous integration and continuous delivery (CI/CD) Jenkins pipeline that delivers your application payloads onto the enterprise Kubernetes platform, Red Hat OpenShift. You see how zero-downtime deployment patterns can be part of your release process when you are using a container platform based on Kubernetes.
Automating your build, test, and deployment processes can improve reliability and reduce the need for rollbacks. However, we’ll show you how rollbacks can be handled too.
Register now and join the live presentation at 12pm EDT, Thursday, July 19th.

Can you “foresee the feature?” Do you know if proposed changes to your application will have the desired impact to your business? Let’s drop the crystal ball approach and start practicing some hypothesis-driven development so you can test your assumptions. Not every new feature is guaranteed to be a success. Some might just waste time and increase your technical debt. Join us for the next online DevNation Live on July 5th at 12pm EDT for Feature Toggles and Hypothesis-driven Development, presented by Red Hat director of Developer Experience, Edson Yanaga.
In this session, we’ll demonstrate how feature toggles can be incorporated into your software development process to let you quickly assess the business results of changes. By toggling functionality on and off, you can measure the impact and make better decisions based on real data.
Join us to gain an understanding of how the use of hypotheses, not requirements, can help you deliver what your business actually requires while learning quickly what works and what does not.

A significant challenge of moving from a traditional monolithic application design to a microservices-based architecture is the ability to monitor the business transaction flow of events throughout your entire distributed system. Join us for the next online DevNation Live on June 21st at 12pm EDT for Advanced Microservices Tracing with Jaeger, presented by Red Hat software engineers Pavol Loffay and Juraci Paixão Kröehling.
In this session, we’ll examine in detail the Cloud Native Computing Foundation (CNCF) OpenTracing API, a consistent, expressive, vendor-neutral API for distributed tracing and context propagation. We will also analyse Jaeger, an open source distributed tracing system inspired by Google Dapper and OpenZipkin.
Join us to gain an understanding of Jaeger’s open source distributed tracing system and how it can help you monitor and troubleshoot microservices-based distributed systems.
Watch the video of the recorded session:

Join us for the next online DevNation Live on June 7th at 12pm EDT for Your Journey to a Serverless World—An Introduction to Serverless, presented by Kamesh Sampath and hosted by Burr Sutter. Serverless computing is an emerging architecture that represents a shift in the way developers build and deliver software systems. By removing application infrastructure concerns, development and deployment are simplified, allowing developers to focus on writing code that delivers value. Additionally, operational costs can be reduced by only consuming resources when needed to respond to application events.
In this session, we’ll learn what serverless is and what it means to a developer. Then, we’ll quickly deploy a serverless platform using Apache OpenWhisk on Kubernetes. Using this platform, we’ll demystify which Java™ programming model you should use in a serverless environment. And finally, we’ll look at tools that can make your serverless journey quick, easy, and productive.
Watch the recorded session and view the slides.

Join us for the next online DevNation Live on May 17th at 12pm EDT for Serverless and Servicefull Applications: Where Microservices Complements Serverless hosted by Burr Sutter. Serverless is a misnomer. Your future cloud-native applications will consist of both microservices and functions, wrapped in Linux containers, but in many cases where you, the developer, will be able to ignore the operational aspects of managing the infrastructure and even much of the runtime stack.
In this technical session, we will start by using Apache Whisk, a Functions-as-a-Service (FaaS) engine, deployed on Kubernetes and Red Hat OpenShift to explore how you can complement cloud-native Java applications (microservices) with serverless functions. Next, we’ll open up a serverless web application architecture and deploy an API Gateway into the FaaS platform to examine the microservices talking to the serverless functions. We finish with a look at how event sinks and event sources map in the serverless world.

In case you missed it, Jakarta EE is officially out! Java EE was given a new home at the Eclipse Foundation and on February 26, 2018 Jakarta EE was chosen as the new name for Java EE. Join us at the next online DevNation Live Tech Talk on Thursday, May 3rd at 12pm EDT. The topic is “Jakarta EE: The Future of Java EE” presented by Dr. Mark Little, and hosted by Burr Sutter.
Java EE has been the dominant enterprise Java standard for well over a decade. With the release of Jakarta EE, we all have a chance to collaborate and build on the good things it inherits, while working to evolve those pieces that were perhaps never quite what was needed.
What does this mean for the future of enterprise Java and traditional Java application servers? Join us to gain an understanding of where Jakarta EE is heading and how you can help drive the future of enterprise Java.
Register now and join the live presentation at 12pm EDT, Thursday, May 3rd.
