In just a matter of weeks, the world that we knew changed forever. The COVID-19 pandemic came swiftly and caused massive disruption to our healthcare systems and local businesses, throwing the world’s economies into chaos. The coronavirus quickly became a crisis that affected everyone. As researchers and scientists rushed to make sense of it, and find ways to eliminate or slow the rate of infection, countries started gathering statistics such as the number of confirmed cases, reported deaths, and so on. Johns Hopkins University researchers have since aggregated the statistics from many countries and made them available.
In this article, we demonstrate how to build a website that shows a series of COVID-19 graphs. These graphs reflect the accumulated number of cases and deaths over a given time period for each country. We use the Red Hat build of Quarkus, Apache Camel K, and Red Hat AMQ Streams to get the Johns Hopkins University data and populate a MongoDB database with it. The deployment is built on the Red Hat OpenShift Container Platform (OCP).

The Quarkus community is excited to announce the Supersonic, Subatomic Java Hackathon for developers to create Kubernetes-native applications for a chance to win $30,000 in prizes. This hackathon is a great opportunity to learn about the future of cloud-native Java development and showcase your coding skills.
If you are new to Quarkus, don’t worry. The community will be there to help and support you with a number of enablement sessions (see below) throughout the hackathon including an opening ceremony, weekly office hours, and the DevNation Quarkus Master Course series.
The hackathon will run from Monday, June 15th through Wednesday, July 22nd culminating in a “live” judging and award ceremony on Friday, August 14th.

Java was introduced 25 years ago, and to this day, remains one of the most popular programming languages among developers. However, Java has developed a reputation for not being a good fit for cloud-native applications. Developers look for (and often choose) alternative frameworks such as Go and Node.js to support their cloud-native development requirements.
Why learn another language when you can use your existing skills? Quarkus allows Java developers to leverage their expertise to develop cloud-native, event-driven, reactive, and serverless applications. Quarkus provides a cohesive Java platform that feels familiar but new at the same time. Not only does it leverage existing Java standards, but it also provides a number of features that optimize developer joy, including live coding, unified configuration, IDE plugins, and more.
Recently, Red Hat announced support for Quarkus. With Quarkus, Red Hat advances Java on Kubernetes and bridges the gap between traditional Java applications and cloud-native environments.

Serverless architecture has recently taken center stage in cloud-native application deployment: Enterprises started to see the benefits that serverless applications bring to them, such as agility, rapid deployment, and resource cost optimization. As with any other new technology, there were multiple ways to approach and employ serverless technologies, such as Function-as-a-Service (FaaS) and Backend-as-a-Service (BaaS)—that is, running your applications as ephemeral containers—with the ability to scale up and down automatically.

While Spring Boot has long been the de-facto framework for developing container-based applications in Java, the performance benefits of a Kubernetes-native framework are hard to ignore. In this article, I will show you how to quickly migrate a Spring Boot microservices application to Quarkus. Once the migration is complete, we’ll test the application and compare startup times between the original Spring Boot application and the new Quarkus app.
