Jenkins may refer to:
Continuous integration (CI) is the practice, in software engineering, of merging all developer working copies to a shared mainline several times a day. It was first named and proposed by Grady Booch in his 1991 method, although Booch did not advocate integrating several times a day. It was adopted as part of extreme programming (XP), which did advocate integrating more than once per day, perhaps as many as tens of times per day.
The main aim of CI is to prevent integration problems, referred to as "integration hell" in early descriptions of XP. CI isn't universally accepted as an improvement over frequent integration, so it is important to distinguish between the two as there is disagreement about the virtues of each.
In XP, CI was intended to be used in combination with automated unit tests written through the practices of test-driven development. Initially this was conceived of as running all unit tests in the developer's local environment and verifying they all passed before committing to the mainline. This helps avoid one developer's work-in-progress breaking another developer's copy. If necessary, partially complete features can be disabled before committing using feature toggles.
Leeroy Jenkins is an Internet meme named for a player character created by Ben Schulz in Blizzard Entertainment's MMORPG World of Warcraft. The character became popular due to a video of the game that circulated on the Internet. The phenomenon has since spread beyond the boundaries of the gaming community into other online and mainstream media.
The video was released by a World of Warcraft player guild, featuring a group of players discussing a detailed battle strategy for their next encounter while Leeroy is away from his computer, fixing a meal. This risky plan is needed specifically to help Leeroy, yet it is ruined when Leeroy returns and, ignorant of the strategy, immediately charges headlong into battle shouting his own name in a stylized battle cry. His companions rush to help, but Leeroy's actions ruin the meticulous plan, and all of the group members are massacred.
Part of the satire in the video was the complex battle plan itself, which — evident only to fellow players — represented a fundamental lack of understanding of the game characters' abilities, and would have led to the party's demise even without Leeroy's suicidal charge.
A web server is an information technology that processes requests via HTTP, the basic network protocol used to distribute information on the World Wide Web. The term can refer either to the entire computer system, an appliance, or specifically to the software that accepts and supervises the HTTP requests.
The primary function of a web server is to store, process and deliver web pages to clients. The communication between client and server takes place using the Hypertext Transfer Protocol (HTTP). Pages delivered are most frequently HTML documents, which may include images, style sheets and scripts in addition to text content.
A user agent, commonly a web browser or web crawler, initiates communication by making a request for a specific resource using HTTP and the server responds with the content of that resource or an error message if unable to do so. The resource is typically a real file on the server's secondary storage, but this is not necessarily the case and depends on how the web server is implemented.
Amazon Elastic Compute Cloud (EC2) forms a central part of Amazon.com's cloud-computing platform, Amazon Web Services (AWS), by allowing users to rent virtual computers on which to run their own computer applications. EC2 encourages scalable deployment of applications by providing a web service through which a user can boot an Amazon Machine Image to configure a virtual machine, which Amazon calls an "instance", containing any software desired. A user can create, launch, and terminate server-instances as needed, paying by the hour for active servers - hence the term "elastic". EC2 provides users with control over the geographical location of instances that allows for latency optimization and high levels of redundancy.
In November 2010 Amazon switched its own retail website to using EC2 and AWS.
Amazon announced a limited public beta test of EC2 on August 25, 2006, offering access on a first-come, first-served basis. Amazon added two new instance types (Large and Extra-Large) on October 16, 2007. On May 29, 2008, two more types were added, High-CPU Medium and High-CPU Extra Large. There are twelve types of instances available.

Many members of the XDA community come to learn and begin in the exciting world of software development. Once you've gone through the development process and written your software, you need to ensure that maintenance does not cause additional problems and the results are always completely reproducible. This is where a build automation system comes in to play. Jenkins is one such software which allows you to keep a hands-off approach to building and releasing your software. In this episode of XDA Developer TV, AdamOutler talks about Jenkins. Jenkins is a build automation software which runs on Linux and Mac, as well as Windows with some effort. Jenkins can be triggered by Git or Subversion commit hooks on each commit and will allow a developer or project manager to know the build status of...
This DevOps Jenkins Tutorial on what is Jenkins ( Jenkins Tutorial Blog Series: https://goo.gl/JebmnW ) will help you understand what is Continuous Integration and why it was introduced. This tutorial also explains how Jenkins achieves Continuous Integration in detail and includes a Hands-On session around Jenkins by the end of which you will learn how to compile a code that is present in GitHub, Review that code and Analyse the test cases present in the GitHub repository. The Hands-On session also explains how to create a build pipeline using Jenkins and how to add Jenkins Slaves. The Hands-On session is performed on an Ubuntu-64bit machine in which Jenkins is installed. To learn how Jenkins can be used to integrate multiple DevOps tools, watch the video titled 'DevOps Tools', by click...
This video is part one in a series of five videos. In this series, I'll take you through the process of installing and configuring a Jenkins Continuous Integration Server on an Amazon EC2 instance. We'll see how to set up Jenkins to build a Java project using Maven, pulling the project from GitHub automatically, each time a change is pushed to a GitHub repository. We'll also see how to generate line coverage reports on our project's unit tests using junit in conjunction with the Jacoco plugin.
