DevOps Engineering - A Complete Guide (Udemy.com)

A warm welcome to the DevOps Engineering course by Uplatz.

Uplatz provides this comprehensive training on DevOps covering four of the most important and popular elements constituting an integrated DevOps system. This DevOps course focuses on the detailed understanding and implementation of:

1. Git and GitHub - free, open source, distributed version control system

2. Apache Maven - tool for build automation including software project management and comprehension

3. JUnit - unit testing framework for the Java programming language

4. Apache Log4j - java-based logging utility and reliable, fast and flexible logging framework (APIs)

The term 'DevOps' was introduced by combining software “development” (Dev) and “operations” (Ops.) The aforesaid term was coined by Patrick Debois in 2009 to make way for quick and effective delivery of software updates, bug fixes, and features.

DevOps, essentially as an approach or a work culture, is implemented by the right amalgamation of collaboration, automation, integration, continuous delivery, testing and supervising.

Prior to the introduction of DevOps, the traditional or classic waterfall model was followed for software delivery. This process model involved a sequential flow of a defined set of phases where the output of one phase becomes the input of the next phase. Therefore, all the phases are dependent on each other, and the completion of one phase marks the beginning of the other. Despite the simplicity of SDLC, it has been found to have several defects. It has been observed that in the ever-changing contemporary world, a business is met with multifaceted problems which require quick fixes. Changes in the product like adding new features, fixing bugs, etc. require it to go through at least a few different silos in traditional SDLC, causing delays and increasing cost.

DevOps resolves these bottlenecks and is a more inclusive approach to the software development process, where the development and operations teams work collaboratively on the project. Resultantly, the software development life cycle is shortened with the help of faster feedback loops for more frequent delivery of updates and features.

Considering the most important elements of DevOps viz. consistency (version control), build automation, testing, logging & supervision, this course covers the most popular tools & technologies used in DevOps. This DevOps course will help you learn the important DevOps building blocks and tools viz. Git, Maven, JUnit, and Log4j, thus opening a world of opportunities for you in DevOps engineering and project management.

Git

Git is an open-source distributed version control system. It is designed to handle minor to major projects with high speed and efficiency. It is developed to co-ordinate the work among the developers.

By far, the most widely used modern version control system in the world today is Git. Git is a mature, actively maintained open source project originally developed in 2005 by Linus Torvalds, the famous creator of the Linux operating system kernel. A staggering number of software projects rely on Git for version control, including commercial projects as well as open source. Developers who have worked with Git are well represented in the pool of available software development talent and it works well on a wide range of operating systems and IDEs (Integrated Development Environments).

Git has been designed with the integrity of managed source code as a top priority. The content of the files as well as the true relationships between files and directories, versions, tags and commits, all of these objects in the Git repository are secured with a cryptographically secure hashing algorithm called SHA1. In simple words, Git is a modern and widely used distributed version control system in the world. It is developed to manage projects with high speed and efficiency. The version control system allows us to monitor and work together with our team members at the same workspace.
