Arth - Task 11.2
Ansible works by connecting to your nodes and pushing out small programs, called Ansible modules to them. … Ansible then executes these modules (over SSH by default), and removes them when finished. Your library of modules can reside on any machine, and there are no servers, daemons, or databases required.
Simple Human readable automation, No special coding skills needed, Tasks executed in order, Get productive quickly Powerful ,App deployment, Configuration management, Workflow orchestration, Orchestrate the app lifecycle, Agentless architecture, Uses OpenSSH and WinRM, No agents to exploit or update, Predictable, reliable and secure, Reasons for learning Ansible
Lets see how NASA is solving challenges using Ansible
NASA needed to move roughly 65 applications from a traditional hardware based data center to a cloud-based environment for better agility and cost savings.
The rapid timeline resulted in many applications being migrated to a cloud environment.This created an environment spanning multiple virtual private clouds (VPCs) and AWS accounts that could not be easily managed.
Even simple things, like ensuring every system administrator had access to every server, or simple patching, were extremely burdensome.
Leverage Ansible Tower was implemented to manage and schedule the cloud environment .
As a result of implementing Ansible Tower, NASA is better equipped to manage its AWS environment. Tower allowed NASA to provide better operations and security to its clients. It has also increased efficiency as a team.
✔Updating nasa.gov went from over 1 hour to under 5 minutes
✔ Patching updates went from a multi-day process to 45 minutes
✔ Achieving near real-time RAM and disk monitoring (accomplished without agents)
✔ Provisioning OS Accounts across entire environment in under 10 minutes
✔ Baselining standard AMIs went from 1 hour of manual configuration to becoming an invisible and seamless background process
✔ Application stack set up from 1–2 hours to under 10 minutes per stack
