Getting Started with Containers & Microservices

DevOps teams are adopting containers and microservices, two of many new tools and practices that are offering solid business benefits. Developers use containers and microservices in many tasks, from app delivery to migration of legacy systems to cloud servers. The increased popularity in containers and microservices can be attributed to their impact on agile cloud environments, with benefits that include increased efficiency, greater speed of delivery, and the ability to do more with existing resources. And while the benefits of containers and microservices are causing an increase in usage, there are also complexities with it.

Docker Containerization Cookbook
Docker is the world's leading software containerization platform. Docker containers wrap a piece of software in a complete file system 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.


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.
