19:00 Kubernetes. From 0 to Production-Grade with Java

In this 90 minute session Kevin talked (and demo!) about what it means to be a good Java Cloud Citizen - which, as we found out, is more than merely putting an application in a container and deploying it. 

We learned that to optimize our Java application's performance and resilience in the cloud, it is essential to consider factors such as providing real-time health status through fine-grained metrics, and also ensuring fast start up, and avoiding excessive resource consumption within the cluster. 

Kevin also explained that being a good Cloud Citizen also involves streamlining configuration, deployment and upgrade processes. By integrating these tasks seamlessly, the application can facilitate smooth deployments and upgrades, which will lead to more efficiency and ease of management. 

Kevin then embarked on a journey to develop a perfect(ish) Cloud Native Java Application with Quarkus. This journey encompassed a comprehensive understanding of both the development and operational perspectives to optimize applications for the cloud environment. We got an overview of the Kubernetes basics from a Java developer’s perspective and learnt step-by-step how to build and configure our application to make it production ready on Kubernetes.
