* PROVISIONING - Your apps have to live somewhere. If you’re PXE booting and kickstarting bare-metal servers or VMs, or creating virtual or cloud instances from templates, Ansible and Ansible Tower help streamline the process. * CONFIGURATION MANAGEMENT - Centralizing configuration file management and deployment is a common use case for Ansible, and it’s how many power users are first introduced to the Ansible automation platform. * APPLICATION DEPLOYMENT - When you define your application with Ansible, and manage the deployment with Tower, teams are able to effectively manage the entire application lifecycle from development to production. * CONTINUOUS DELIVERY - Creating a CI/CD pipeline requires buy-in from numerous teams. You can’t do it without a simple automation platform that everyone in your organization can use. * SECURITY & COMPLIANCE - When you define your security policy in Ansible, scanning and remediation of site-wide security policy can be integrated into other automated processes and instead of being an afterthought, it’ll be integral in everything that is deployed. * ORCHESTRATION - Configurations alone don’t define your environment. You need to define how multiple configurations interact and ensure the disparate pieces can be managed as a whole. Out of complexity and chaos, Ansible brings order.

* 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. * 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. * 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. * Distributed - Jenkins can easily distribute work across multiple machines, helping drive builds, tests and deployments across multiple platforms faster.
