* Ansible seamlessly unites workflow orchestration with configuration management, provisioning, and application deployment in one easy-to-use and deploy platform. * Regardless of where you start with Ansible, you’ll find our simple, powerful and agentless automation platform has the capabilities to solve your most challenging problems. * 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. Ansible Playbooks keep your applications properly deployed (and managed) throughout their entire lifecycle. * 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. * COMMUNITY-POWERED - Ansible is the most popular open source automation tool on GitHub today. With over 2,000 contributors submitting new modules all the time, rest assured that what you are automating is covered in Ansible already, or will be very soon. * ENTERPRISE READY - Ansible Tower by Red Hat builds on the underlying Ansible automation engine by adding control, security, and delegation capabilities. With Ansible and Tower, your team can automate –and your business can innovate.

* Frontend - Run thousands of Jasmin unit tests with PhantomJS. Run Cucumber specs against your Rails app with Chrome Driver with 20 different strongly-isolated server / client pairs in parallel. Ruby, Python, Java, Node, Go, and more. CircleCI is flexible to work in your environment. * Backend - Whether you have a Rails monolith or a network of Node.js microservices, CircleCI can handle any backed platform that runs Linux. We also support dependencies from Postgres to Docker or anything else you care to sudo apt-get install. Oh and did we mention we run everything really fast? * Mobile - Android or iOS, hybrid or native, you can build and test your mobile app on CircleCI. Got some backend services for your mobile app? Let us build, test and deploy those for you. * Docker - CircleCI has been built on Linux containers from the start so when Docker took off, we were excited for a chance to put our container skills to work for our customers. Anyway, we think we’ve built the best solution to taking your app from Docker files to production. * Source - CircleCI builds start right away with a hook from GitHub. No plugins to worry about, and no polling. Granular checkout key options support pulling from multiple projects and our source caches ensures that checkouts are lightning-fast. * Resolve Dependencies - CircleCI automatically uses language-specific tools like rvm and virtualenv to ensure dependencies are installed into an isolated environment. After the first build, the CircleCI dependency cache saves all your dependencies so they can be re-installed in no time from the next build moving forward. * Build - Not every language requires a compilation step, but if yours does, we're standing by with all of your favorite build tools. We have compilers for Java (many versions), Scala, Haskell, CoffeeScript, Less, and more ready to go. We also support your favorite build tools, like Gradle, Maven, Leiningen, and Cabal. Perhaps you're writing Smalltalk or OCaml, well those might not be preinstalled, but you can always sudo apt-get to suit your build environment. * Test - It goes without saying that CircleCI should be really smart about running your tests. We think we do it better than anyone else with our automatic test parallelization and detailed test failure reporting. CircleCI has first-class support for a pile of test runners, from RSpec to Nose, but we can handle anything that returns an exit code.
