With the right tools, building scalable applications can be much easier than it seems. Eclipse MicroProfile allows you to build such applications easily and you get a variety of options to scale them if you add distributed data grids. These can become a backbone for building horizontally scalable services, while at the same time providing flexible caching to scale up their performance vertically.
MicroProfile, RxJava, React.js - what else do you need to build lightweight but robust reactive systems efficiently with opensource tools? Maybe something for effective data processing and distributed persistence? You can have it too with Kafka and Hazelcast. Now let’s have a look at how to assemble all together in almost no time, using Payara Micro.
