Have you ever wondered how you can improve the performance of your applications under high load? You've probably heard that reactive design can help meet better response time and make your applications more flexible. In this presentation, I will show that you don’t need to rewrite your Java EE applications from scratch to achieve that!
The Payara Server 173 release includes a technical preview of an upcoming REST Monitoring Service, which is a new service which exposes JMX monitoring MBeans over HTTP. One big problem with JMX is that JMX monitoring uses RMI (Remote Method Invocation), which can lead to a few nightmares if, for example, you have a firewall which blocks connections over RMI ports. The REST monitoring service in Payara Server now provides a service which will be very familiar to users of Jolokia in that it makes this monitoring data available over HTTP, making the data available in a more standard format (JSON) and accessible over a standard HTTP connection.
In the official announcement published on the Aquarium blog today, Oracle revealed that it seriously considers moving Java EE to an open source foundation.
In order to make a cluster of servers appear as one server, you need to introduce a load balancer. A load balancer will accept a request, and redirect it to one of the members of the cluster depending on a given configuration. A web server such as NGINX or Apache can act as this load balancer as well as a reverse proxy, which allows the web server to load balance requests across the cluster, act as a termination point for SSL connections to reduce strain on the cluster, as well as cache server content for quicker access. In this blog, we will set up NGINX as a reverse proxy and secure it using SSL.
Back in May, we announced the 172 release of Payara Server and mentioned a preview of our Maven plugin for Payara Micro, available on GitHub. Since then, we have released the plugin to Maven Central so, to illustrate it's use, I'll be revisiting my earlier blog on another feature of Payara Micro 172 - the ability to use Payara Micro as a JMS consumer.
