DevOps

DevOps basically is a set of practices of software development (Dev) and IT operations (Ops) together. It aims to shorten the systems development life cycle and provide continuous delivery with high software quality.DevOps is complementary to Agile software development; several DevOps aspects came from the Agile methodology. In simple terms: "a set of practices intended to reduce the time between committing a change to a system and the change being placed into normal production, while ensuring high quality" It consists of six steps :

• Plan
• Build
• Continuous integration and deployment
• Monitor
• Operate
• Continuous feedback

DevOps tools to begin with :

Docker(Container Platform)

Docker is a DevOps technology suite. It allows DevOps teams to build, ship, and run distributed applications. This tool allows users to assemble apps from components and work collaboratively. Docker makes development efficient and predictable Docker’s comprehensive end-to-end platform includes UIs, CLIs, APIs, and security that are engineered to work together across the entire application delivery lifecycle. The Docker engine is designed to automate the development, deployment, and management of containerized applications on single nodes. Docker is open-source and compatible with cloud services like AWS, GCP, and Azure Cloud. Docker also runs on Windows and Linux operating systems.

Jenkins(Continuous Integration Tool)

Jenkins is a DevOps tool for monitoring the execution of repeated tasks. It is one of the best software deploy tools which helps to integrate project changes more easily by quickly finding issues.

• It increases the scale of automation
• Jenkins requires little maintenance and has a built-in GUI tool for easy updates.
• It offers 400 plugins to support building and testing virtually any project.
• It is a Java-based program ready to run with Operating systems like Windows, Mac OS X, and UNIX
• It supports continuous integration and continuous delivery
• It can easily be set up and configured via the web interface
• It can distribute tasks across multiple machines thereby increasing concurrency.

Git(Version control tool)

Git is perhaps the best and most widely used version control tool in a development era characterized by dynamism and collaboration. Version control provides developers with a means by which they can keep track of all the changes and updates in their codes such that in the event of a mishap, it is quite easy to return to and use the previous versions of the code and Git happens to be the best for many reasons.

Maven(Build Tool)

It is one of the most important DevOps tools for building projects. It offers a host of benefits to its users. It eases the build and monitoring process through automation and maintains a uniform build process allowing for consistency and efficiency. Maven can build and manage projects written in Java or C#, Ruby, Scala, and other languages using project object model (POM) plugins. It's designed to manage documentation, reporting, distribution, releases, and other dependencies processes.

Selenium(Testing tool)

Selenium is a top open-source testing framework for web applications that supports all major browsers and platforms like Linux, Windows, and macOS. The beauty of Selenium is that it integrates with a wide range of programming languages including Python, C#, Ruby, Java, JavaScript, PHP, and PERL, and several other automation test frameworks.

Selenium test suite comprises the following:

• Selenium IDE (Integrated Development Environment) for creating and running test cases for exploratory testing and recording test playbacks
• Selenium client API allows developers to write test scripts directly in various programming languages instead of having to first write them in the Selenese programming language.
• Selenium WebDriver features language-specific bindings for writing test scripts.
• Selenium Grid is a smart proxy server that allows tests to be executed on multiple browsers and operating systems in parallel.
• Selenium Remote Control server written in Java communicates Selenium commands to browsers for execution.
