Scalability is often a key issue for many growing organizations. That’s why many organizations use Apache Kafka, a popular messaging and streaming platform. It is horizontally scalable, cloud-native, and versatile. It can serve as a traditional publish-and-subscribe messaging system, as a streaming platform, or as a distributed state store. Companies around the world use Apache Kafka to build real-time streaming applications, streaming data pipelines, and event-driven architectures.

EclipseCon Europe is almost here, and many Red Hatters are working furiously to make the show as valuable as possible for attendees. (We’re partly doing it for ourselves as well, of course, because it’s a great opportunity to get the entire Che/Theia community together.) If you aren’t familiar with Eclipse Che, it’s is a next-generation cloud IDE and developer workspace server for teams and organizations. Theia is an extensible open-source framework to develop multi-language IDEs for the cloud and desktop using state-of-the-art web technologies.

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.

I am happy to announce that DevConf.US registration is now open and the schedule is live. DevConf events are free, but online registration is required. If you are available August 17–19, 2018, we would love for you to come and participate.
Similar to DevConf.CZ, DevConf.us 2018 is the 1st annual, free, Red Hat sponsored technology conference for community project and professional contributors to Free and Open Source technologies (FOSS) at the Boston University in the historic city of Boston, USA.
You should consider attending this DevConf event if you are:
- A developer
- A technology architect
- An IT consultant
- An IT student or a teacher from an IT university/faculty
- Or simply an IT enthusiast interested in the latest trends in open source and emerging digital technologies

July 19th DevNation Live: Container pipeline master: Continuous integration + continuous delivery with Jenkins
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.
Register now and join the live presentation at 12pm EDT, Thursday, July 5th.

The scavenger hunt game developed for the audience to play during the Red Hat Summit 2018 demo used Red Hat Data Grid as storage for everything except the pictures taken by the participants. Data was stored across three different cloud environments using cross-site replication. In this blog post, we will look at how data was flowing through Data Grid and explain the Data Grid features powering different aspects of the game’s functionality.

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:

If you saw or heard about the multi-cloud demo at Red Hat Summit 2018, this article details how we ran Red Hat Data Grid in active-active-active mode across three cloud providers. This set up enabled us to show a fail over between cloud providers in real time with no loss of data. In addition to Red Hat Data Grid, we used Vert.x (reactive programming), OpenWhisk (serverless), and Red Hat Gluster Storage (software-defined storage.)
This year’s Red Hat Summit was quite an adventure for all of us. A trip to San Francisco is probably on the bucket list of IT geeks from all over the world. Also, we were able to meet many other Red Hatters, who work remotely for Red Hat as we do. However, the best part was that we had something important to say: “we believe in the hybrid/multi cloud” and we got to prove that live on stage.
