Introduction
Infrastructure Provisioning for the TAMV Online system encompasses the automated setup and management of the underlying hardware and software resources required to run the application. This process ensures that environments are consistent, scalable, and reproducible across development, testing, and production stages.
The system utilizes a combination of Infrastructure as Code (IaC) tools and container orchestration to manage its complex ecosystem. This approach allows for the management of the "most ambitious system created by a single human mind" with high precision and minimal manual intervention.

Cloud Resource Management
The project employs Terraform to define and manage cloud infrastructure. This ensures that the virtual private clouds (VPC), compute instances, and storage buckets are provisioned according to strict specifications.
Terraform Configuration
The core infrastructure is defined in main.tf, which specifies the provider and the resources to be created. Variables are used to allow for environment-specific configurations.
The diagram above illustrates the workflow of provisioning cloud resources using Terraform.

Key Infrastructure Components
| Component | Technology | Description |
|---|---|---|
| Compute | AWS EC2 / DigitalOcean Droplets | Host for the application containers |
| Networking | VPC / Subnets | Isolated network environment for system security |
| Storage | S3 / Block Storage | Persistent storage for system logs and user data |
Sources: infrastructure/terraform/main.tf
Container Orchestration and Deployment
Once the base infrastructure is provisioned, the application services are deployed using Docker Compose. This layer manages the lifecycle of individual service containers.
Service Stack
The docker-compose.yml file defines the multi-container application, including the web frontend, backend API, and database services. It handles networking between containers and volume mapping for persistence.
This diagram shows the relationship and communication flow between the containerized services managed by Docker Compose.

Environment Initialization
The setup_env.sh script automates the initial configuration of the host machine. This includes installing dependencies, configuring environment variables, and preparing the file system for the application.
Initialization Steps
- System Update: Ensures all host packages are current.
- Dependency Installation: Installs Docker, Docker Compose, and Terraform.
- Environment Configuration: Generates
.envfiles from templates. - Permission Management: Sets appropriate directory permissions for log and data volumes.

Conclusion
The infrastructure provisioning system of TAMV Online provides a robust foundation for the application. By leveraging Terraform for cloud resources and Docker Compose for service orchestration, the project achieves a high degree of automation and reliability, supporting its ambitious goals.
