It’s a search engine based on the Lucene library and allows you how to become a java developer to reliably search, analyze, and visualize your data. Elasticsearch is often used together with Kibana, Beats, and Logstash, which form the Elastic Stack. The basic principles of service-oriented architecture are independent of vendors, products, and technologies. It sounds very similar to microservice, where also the application is divided into multiple services, but the key difference is size, microservice, as the name suggests, is much smaller in size and scope.
