Spring Framework Cookbook The Spring Framework is an open-source application framework and inversion of control container for the Java platform. The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE platform. Although the framework does not impose any specific programming model, it has become popular in the Java community as an alternative to, replacement for, or even addition to the Enterprise JavaBeans (EJB) model. In this 200 page ebook, we provide a compilation of Spring Framework tutorials that will help you kick-start your own programming projects. We cover a wide range of topics, from basic usage and best practices, to specific projects like Boot and Batch. With our straightforward tutorials, you will be able to get your own projects up and running in minimum time.

Elasticsearch Tutorial Elasticsearch is a search engine based on Lucene. It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents. Elasticsearch is developed in Java and is released as open source under the terms of the Apache License. Elasticsearch is the most popular enterprise search engine followed by Apache Solr, also based on Lucene. Elasticsearch can be used to search all kinds of documents. It provides scalable search, has near real-time search, and supports multitenancy. Elasticsearch is distributed, which means that indices can be divided into shards and each shard can have zero or more replicas. Each node hosts one or more shards, and acts as a coordinator to delegate operations to the correct shard(s). Rebalancing and routing are done automatically.

Docker Cookbook Docker is the world's leading software containerization platform. Docker containers wrap a piece of software in a complete filesystem that contains everything needed to run: code, runtime, system tools, system libraries anything that can be installed on a server. This guarantees that the software will always run the same, regardless of its environment. Docker provides an additional layer of abstraction and automation of operating-system-level virtualization on Linux. Docker uses the resource isolation features of the Linux kernel such as cgroups and kernel namespaces, and a union-capable file system such as OverlayFS and others to allow independent "containers" to run within a single Linux instance, avoiding the overhead of starting and maintaining virtual machines.

JMeter Tutorial JMeter is an application that offers several possibilities to configure and execute load, performance and stress tests using different technologies and protocols. It allows simulating different type of requests against all kind of databases, FTP, HTTP, HTTPS or other kind of servers. Originally JMeter was designed to test web applications, but its functionality has expanded and nowadays allows testing against almost any kind of program and can be used to perform functional tests in your applications.Thisis a standalone, reference guide to provide a framework on how to work with JMeter and help you quickly kick-start your JMeter applications!
