Infrastructure as Code

Infrastructure as Code (IaC)

A method of managing and provisioning infrastructure using configuration files instead of manual hardware configuration.

IaC Purpose

Allows automated, consistent, and repeatable deployment of network infrastructure.

IaC Deployment

Administrators create definition files that describe the infrastructure to be built.

Definition Files

Configuration files that specify how infrastructure such as servers, routers, and firewalls should be deployed.

Automation in Networking

The process of automatically configuring and managing infrastructure using scripts or configuration files.

IaC Consistency

Ensures identical infrastructure can be deployed across different environments.

Configuration Drift

A situation where systems become inconsistent due to manual configuration changes over time.

Configuration Drift Prevention

IaC prevents drift by rebuilding infrastructure from standardized configuration files.

Infrastructure Replication

IaC allows administrators to duplicate environments such as development, testing, and production.

Cloud Infrastructure Automation

Cloud platforms can automatically build resources based on IaC definition files.

Playbook

A predefined set of automated steps used to respond to events or perform configuration tasks.

Automation Playbooks

Scripts that define responses to issues such as security incidents or system failures.

SOAR (Security Orchestration, Automation, and Response)

A platform that automates security operations and incident response.

SOAR Purpose

Coordinates automated responses to security threats using playbooks and workflows.

Source Control

A system used to track and manage changes to configuration files over time.

Version Control

The process of managing file revisions and maintaining a history of changes.

Git

A popular version control system used to manage infrastructure configuration files.

Change Tracking

Source control systems allow administrators to track modifications made to infrastructure definitions.

Configuration Collaboration

Multiple administrators can work together on configuration files using version control systems.

Infrastructure Scalability

IaC enables rapid scaling of infrastructure by automatically deploying additional resources.
