Introduction to Red Hat Ansible Automation
Today I am going to talk about Red Hat Ansible. Many of you guys know about Ansible as a configuration management and application deployment tool. It is an open source project and is widely deployed in many of the enterprise networks. Ansible models Enterprise IT infrastructure by outlining how all of your systems inter-relate, rather than just managing one system at a time.
Ansible an open source project works by linking to network nodes and pushing out small programs, called "Ansible modules" to them. These programs are transcribed to be resource models of the desired state of the system. Ansible then executes these modules and removes them when finished.
Let’s talk about what can be automated with the help of Red Hat Ansible. We can automate the infrastructure, Applications, Networks of course, containers, Security and compliance and the cloud infrastructure.

Infrastructure
Ansible is simple and commanding, permitting clients to simply achieve numerous physical devices which comprising the provisioning of bare metal servers, network devices or even storage devices.Ansible supports all virtualization platforms such as VMware, Libvirt, XenServer, Vagrant and RHEV.
With Ansible, we can simply provision, abolish, take record, and achieve your virtual environments. Ansible’s wide-ranging provision permits us to then install and orchestrate across all of your virtual environments once we provisioned them.
Ansible supports different operating systems like Linux, Unix, OS X, Windows, Ubuntu, CentOS, Fedora and many more. Ansible modules exist for handling the installation of software, updates, system configuration, and the handling of system features. And if we have got more specific requirements, Ansible will wrap native commands on any of these platforms, allowing you to automate anything you can imagine.
Applications
Ansible is the easiest method to implement our applications. It provides the power to implement multi-tier applications reliably and steadily, all from one common framework. You can configure wanted services as well as push application objects from one common system.
Networks
Ansible’s simple automation framework means that formerly remote network supervisors can finally speak the same language of automation as the rest of the IT organization, covering the abilities of Ansible to comprise native support for both legacy and open network infrastructure devices. Network devices and systems can now be comprised in an organization's overall automation strategy for a holistic tactic to application workload management.
Containers
Containers as a fundamental part of DevOps workflows since of their flexibility and portability. With containers, developers can construct an application once, and know it will be run in the same way across every environment along the application lifecycle from a developer workstation to QA, to staging, and eventually into production.
Ansible achieves not only the containers themselves, but the circumstances around the containers too. Docker instances still need to run on hosts, and those hosts need to be launched, configured, networked, and coordinated.
Cloud Infrastructure
Clouds are the cluster of the servers with the storage capability. Irrespective if application infrastructure consists of servers, specific OS configurations, virtual private networks, subnets, and even load balancers. Ansible will guarantee the infrastructure meets every need of your application each and every time.
Positioning your clouds with Ansible takes out the presumption from the process. We don’t have to waste time educating complete crews on how to work with each cloud vendor in your environment, and you can belief that every deployment meets all of your policy each and every time.
