Course Details
Ansible is a powerful, agentless automation tool that simplifies the management of IT infrastructure. It offers a flexible, simple, and scalable solution to automate repetitive tasks such as configuration management, application deployment, and orchestration. With its ease of use, extensibility, and active community, Ansible is a leading choice for IT automation, and it is widely used in enterprises and by DevOps teams around the world.
Ansible
Ansible is a configuration management and automation tool that automates IT infrastructure management tasks. It allows system administrators to define the desired state of their infrastructure and applications, and then automatically brings systems into that state. Ansible was created by Michael DeHaan in 2012 and is now maintained by Red Hat.

Key Features of Ansible
Agentless Architecture: Unlike other tools like Chef or Puppet, Ansible doesn't require any software to be installed on the target machines.
Declarative Language (YAML): Ansible playbooks, which define automation tasks, are written in YAML (Yet Another Markup Language).
Modules: Ansible comes with a wide range of built-in modules that handle common tasks like package installation, user management, service control, file management, and more.
Use Cases for Ansible
Configuration Management:Ansible excels in managing system configurations.
Application Deployment: Developers use Ansible to automate the deployment of applications.
Cloud Infrastructure Management: Ansible is widely used to automate the provisioning and management of cloud infrastructure .
How Ansible Works
Control Node: The machine that runs Ansible commands and playbooks is called the control node. It can be any system (usually a Linux machine), and from this node, you manage the target nodes (managed nodes).
Managed Nodes:Managed nodes are the target systems that Ansible will manage. These systems do not require any agent to be installed, as Ansible communicates via SSH (for Linux) or WinRM (for Windows).
Ansible Architecture
Control Node: The control node is the machine where Ansible is installed and from where you run your playbooks or ad-hoc commands.
Inventory: The inventory defines the list of managed nodes (servers or devices) and their grouping. It can be a simple static file or dynamic .
Playbooks: Playbooks are the heart of Ansible automation. They define the set of tasks and instructions that Ansible will execute on the target systems.
Advantages of Ansible
Simple and Easy to Use: Ansible uses YAML, a simple language, making it easy to write and understand playbooks.
No Agents Required: Since Ansible is agentless, there is no need to install additional software on managed nodes. This reduces overhead and complexity.
Scalability: Ansible can manage hundreds or even thousands of nodes, allowing for automation across large infrastructures.
