How to use Liberty Tools for IntelliJ IDEA to enable rapid, easy, and efficient development of cloud-native Java applications with Liberty.

When AutoScale is fully developed, not only will it allow you to change the number of instances in the Deployment Group by implementing additional asadmin commands, but it will also signal the routing systems of the changed configuration and automatically trigger a change in size based on rules around resource usage.

In this first step of the AutoScale development, we have introduced the concept of the Scaling Group into Payara Server Community Edition 5.2021.4 which can alter the number of instances in a Deployment group and implement it for SSH nodes.

The AutoScale feature is in continuous development, with improvements and additional functionality (including addressing the routing issue) planned in our future releases.

The MicroProfile OpenTracing specification defines behaviours and an API for accessing an OpenTracing compliant Tracer object within your JAX-RS application. The behaviours specify how incoming and outgoing requests will have OpenTracing Spans automatically created. The API defines how to explicitly disable or enable tracing for given endpoints.

Jaeger, inspired by Dapper and OpenZipkin, is a distributed tracing system released as open source by Uber Technologies. It is used for monitoring and troubleshooting microservices-based distributed systems.

All companies are software companies, and businesses will always experience the challenge of keeping integrations between users and applications scalable, productive, fast, and of high quality.

To combat this, cloud, microservices, and other modern solutions come up more and more in architectural decisions.

Here is the question: Is Java prepared to deal with these diverse concepts in a corporate environment?

In this day and age, securing enterprise platforms is a challenge that developers and consultants tackle in an uninformed manner, producing subpar solutions in most cases.

This presentation by Ondrej Mihalyi at DevOpsCon showcases the strength of combining MicroProfile and an OAuth service by doing a live demonstration of securing enterprise Java microservices in Kubernetes.
