Cloud computing represents a paradigm shift in the world of application architecture from vertical scalability to horizontal scalability. This new paradigm has much to offer organizations that want to build highly scalable and dynamic applications, but it has its dangers, too – if you’re not careful and purposeful in how you prepare for the cloud, your application could suffer. In this white paper, we’ll discuss how to reap the performance benefits of the cloud and avoid the common pitfalls.     Migrations: 5 steps to successful cloud migration Cloud computing has been gaining momentum for years. As the technology leaves the early adopter phase and becomes mainstream, many organizations find themselves scrambling to overcome the challenges that come with a more distributed infrastructure. One of those difficulties is getting through a major cloud migration. It is one thing to roll out a few applications and cloud pilot projects, it is an entirely different challenge to start using the cloud across multiple lines of business at massive scale. That is the point that organizations are beginning to reach, and the time has come to take a serious look at cloud migration best practices. Read this eBook to meet the cloud world and its importance for businesses moving to the cloud.     Mockito Programming Cookbook Mockito is an open source testing framework for Java released under the MIT License. The framework allows the creation of test double objects (mock objects) in automated unit tests for the purpose of Test-driven Development (TDD) or Behavior Driven Development (BDD). In software development there is an opportunity of ensuring that objects perform the behaviors that are expected of them. One approach is to create a test automation framework that actually exercises each of those behaviors and verifies that it performs as expected, even after it is changed. Developers have created mock testing frameworks. These effectively fake some external dependencies so that the object being tested has a consistent interaction with its outside dependencies.      JUnit Programming Cookbook JUnit is a unit testing framework to write repeatable tests. JUnit has been important in the development of test-driven development, and is one of a family of unit testing frameworks which is collectively known as xUnit that originated with SUnit. A research survey performed in 2013 across 10,000 Java projects hosted on GitHub found that JUnit, (in a tie with slf4j-api), was the most commonly included external library. (Source) In this ebook, we provide a compilation of JUnit tutorials that will help you kick-start your own programming projects. We cover a wide range of topics, from basic usage and configuration, to multithreaded tests and integration with other testing frameworks. With our straightforward tutorials, you will be able to get your own projects up and running in minimum time.
