Introduction
Setting up and managing your cloud environment in an automated way is one of the key concepts for DevOps. In this lesson, you'll learn how to automate the setup and management of your SAP BTP landscape by using the Terraform Provider for SAP BTP.
Infrastructure as Code
Infrastructure as Code (IaC) enables you to automate infrastructure provisioning and management using code instead of manual actions. It helps ensure consistency, scalability, versioning, collaboration, and documentation of your infrastructure.
IaC uses a declarative approach. You define the desired state of the system, including what resources you need and any properties they should have. The IaC tool will take this target configuration and execute the necessary steps to match it.
Idempotency is another key concept. Rerunning a script should always result in the same configuration.
Key benefits of IaC:
- Automation: IaC lays the foundation to automate the provisioning and management of your infrastructure. Infrastructure can be created, modified, and destroyed programmatically, reducing the need for manual intervention and minimizing human error.
- Consistency: Using IaC, you can ensure that your infrastructure is consistently provisioned and configured across different environments, such as development, test, and production. This reduces configuration drift and improves reliability.
- Scalability: IaC allows you to roll out infrastructure in a scalable way. By defining infrastructure configurations in code, you can easily replicate and deploy infrastructure resources in a consistent and repeatable manner.
- Versioning and collaboration: IaC configurations should be stored in version control systems, allowing you to track changes over time and roll back to previous versions if needed. It also enables collaboration among team members, as multiple people can work on the same infrastructure codebase simultaneously.
- Documentation: IaC serves as a form of documentation, providing a clear and concise representation of the desired infrastructure state. It helps in understanding the infrastructure architecture and facilitates knowledge sharing within the team.
