# Backend

The backend infrastructure of Illuvium is hosted on Amazon Web Services (AWS), a leading Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) provider. The core backend services are built using a serverless model, utilising AWS Lambda for its scalability and cost-effectiveness. To ensure data integrity and availability, the primary persistence mechanism is DynamoDB, leveraging its transactional features for atomic, consistent, isolated, durable, and highly available storage solutions. Additionally, Illuvium incorporates a comprehensive suite of AWS monitoring and security services, including CloudWatch, GuardDuty, Inspector, Detective, and Security Hub, to maintain a secure and well-monitored backend environment.
