Ansible
Simple IT Automation
About Ansible
Simplify work. Break down silos. Speed transformation.
Ansible is a universal language, unraveling the mystery of how work gets done. Turn tough tasks into repeatable playbooks. Roll out enterprise-wide protocols with the push of a button. Give your team the tools to automate, solve, and share.
- Automate
- Accelerate
- Collaborate
- Integrate
Ansible Topics
The following are the things covered under Ansible.
PROVISIONING
Ansible can provision the latest cloud platforms, virtualized hosts and hypervisors, network devices and bare-metal servers.
CONFIGURATION MANAGEMENT
Virtualization and cloud technology have increased the complexity and the number of systems to manage is only growing.
APPLICATION DEPLOYMENT
Ansible is the simplest way to deploy your applications. It gives you the power to deploy multi-tier applications reliably and consistently, all from one common framework.
CONTINUOUS DELIVERY
automation is key - but so is simplicity. Your team needs the tools that enable quick turnaround, requiring human intervention only when necessary. That's what Ansible does with one of the easiest paths to continuous delivery in the industry.
SECURITY & COMPLIANCE
In today’s complex IT environments, security is paramount - security of your systems, security of your data, security of your customer’s data.
ORCHESTRATION
Deploying a single service on a single machine can be fairly simple and you have lots of solutions to choose from. You can bake all your configuration into a virtual image, or you can run a configuration management tool
