This document discusses automating IT infrastructure using Ansible. It provides an overview of Ansible and how it can be used to manage devices programmatically through infrastructure as code. Specific examples are given of how Ansible can be used to automate tasks like server deployment, configuration changes, backups and application deployments. The benefits of automation through tools like Ansible are reducing repetitive manual tasks and enabling infrastructure to self-heal through integration with monitoring systems.

2. About Me
https://www.linkedin.com/in/dio-pratama/
IT Infrastructure by the day especially in enterprise networking, sysadmin and data center.
Passionate in programming and automation, business driven and lifelong learner. I believe
that the future of work is all about automation. By leveraging automation, organizations
will move faster and people can contribute more ideas, innovations and deliver more
valuable and excellent masterpiece.

3. Infrastructure as Code : Manage IT Devices Programmatically
Because of hardware is less flexible, it's time for traditional IT Infrastructure to
transform their obsolate operating model to Infrastructure as a Code

8. Ansible Architecture
Host inventory file determines the target
machines where these plays will be executed
Configuration file can be customized to reflect
the settings in your environment
Playbooks consist of one or more tasks that are
expressed either with core modules that
come with Ansible or custom modules that you
can write for specific situations
Modules (also referred to as “task plugins” or
“library plugins”) are discrete units of code that
can be used from the command line or in a
playbook task.

9. Ansible Types
• Free - Open Source
• CLI
• Licensed - 10k USD / Per 100 Nodes
• GUI
• Many features
• Free - Open Source
• GUI
• Same features as Tower

18. IT Infra Automation Architecture
- Create Instances
- Server Provisioning
- Push OS/Image
- Changing Configuration
- Backup & Restore Configuration
- Deploy Application
- Etc
Everything that we can do manually by
SSH and Powershell (windows) console,
It can be done automatically by Ansible

19. Tested For Those Kind of Devices

20. Automate Web Server Deployment (Windows IIS)

21. Automate NAT Configuration (MX-Juniper)

22. Automate VM Deployment & Management (vmware)
RESTful API
- Create new server
- Deploy server from
template
- Upgrade vm resources
- etc
Ansible vmware Modules

23. IT Infrastructure Self Healing
Example Solarwind –Telegram API ConnectionAnsible
Example :
There is an intermittent interface, solarwind detect high CRC and it triggered action
To ansible to shutdown the interface.

26. One important idea in Site Reliability
Engineering is that in order to have a
reliable system, you need to make it out of
interchangeable and replaceable parts that
can fail at any time.
Configuration has two components:
• Configuration syntax that is specific to
vendor or platform.
• Data variables, that are consistent
regardless of the syntax (e.g. SNMP
configuration, NTP server etc.)
or unique for every device e.g.
hostname, IP address etc.
