Jenkins - Automation Tool

Jenkins is free software released under MIT License. Jenkins is an open source automation server written in Java. Jenkins helps to automate the non-human part of software development process, with continuous integration and facilitating technical aspects of continuous delivery. It is a server-based system that runs in servlet containers such as Apache Tomcat. It supports version control tools, including AccuRev, CVS, Subversion, Git, Mercurial, Perforce, ClearCase and RTC, and can execute Apache Ant, Apache Maven and sbt based projects as well as arbitrary shell scripts and Windows batch commands.

Features:

• Continuous Integration and Continuous Delivery - As an extensible automation server, Jenkins can be used as a simple CI server or turned into the continuous delivery hub for any project.
• Easy installation - Jenkins is a self-contained Java-based program, ready to run out-of-the-box, with packages for Windows, Mac OS X and other Unix-like operating systems.
• Easy configuration - Jenkins can be easily set up and configured via its web interface, which includes on-the-fly error checks and built-in help.
• Plugins - With hundreds of plugins in the Update Center, Jenkins integrates with practically every tool in the continuous integration and continuous delivery toolchain.
• Extensible - Jenkins can be extended via its plugin architecture, providing nearly infinite possibilities for what Jenkins can do.
• Distributed - Jenkins can easily distribute work across multiple machines, helping drive builds, tests and deployments across multiple platforms faster.

Azure Functions

Azure Functions is a solution for easily running small pieces of code, or "functions," in the cloud. You can write just the code you need for the problem at hand, without worrying about a whole application or the infrastructure to run it. Functions can make development even more productive, and you can use your development language of choice, such as C#, F#, Node.js, Python or PHP. Pay only for the time your code runs and trust Azure to scale as needed. Azure Functions lets you develop serverless applications on Microsoft Azure.

Here are some key features of Azure Functions:

• Choice of language - Write functions using C#, F#, Node.js, Python, PHP, batch, bash, or any executable.
• Pay-per-use pricing model - Pay only for the time spent running your code. See the Consumption hosting plan option in the pricing section.
• Bring your own dependencies - Functions supports NuGet and NPM, so you can use your favorite libraries.
• Integrated security - Protect HTTP-triggered functions with OAuth providers such as Azure Active Directory, Facebook, Google, Twitter, and Microsoft Account.
• Simplified integration - Easily leverage Azure services and software-as-a-service (SaaS) offerings. See the integrations section for some examples.
• Flexible development - Code your functions right in the portal or set up continuous integration and deploy your code through GitHub, Visual Studio Team Services, and other supported development tools.
• Open-source - The Functions runtime is open-source and available on GitHub.

Azure Functions integrates with various Azure and 3rd-party services. These services can trigger your function and start execution, or they can serve as input and output for your code.

Azure Functions has two kinds of pricing plans:

• Consumption plan - When your function runs, Azure provides all of the necessary computational resources. You don't have to worry about resource management, and you only pay for the time that your code runs.
• App Service plan - Run your functions just like your web, mobile, and API apps. When you are already using App Service for your other applications, you can run your functions on the same plan at no additional cost.
