# Security and Scalability

Silencio is built on a highly secure and scalable infrastructure using Amazon Web Services (AWS) to support backend operations. The following key features ensure robust performance and data protection:

* Load Balancer: AWS Application Load Balancer (ALB) efficiently distributes incoming traffic across multiple backend instances. By dynamically adjusting resources, this ensures consistent performance, high availability, and redundancy during traffic surges.
* Auto-Scaling Strategy: The platform employs an auto-scaling strategy that automatically provisions additional computing resources based on real-time demand. As user activity increases, the infrastructure scales up to maintain performance. During low-traffic periods, it scales down to optimize cost efficiency.
* Managed SQL Cloud Database: AWS RDS Database ensures reliable data handling with features such as automatic backups, updates, and scaling to meet database load. This minimizes downtime and maintains data integrity as user demand grows.
* Strong Network Strategy: Bastion Host manages access to internal resources, restricting direct access to backend services from the public internet and thereby reducing the risk of unauthorized intrusion.
* Observability and Alerts: Silencio has advanced monitoring and automated alerting systems to ensure real-time visibility into operations, enabling prompt responses to anomalies and the maintenance of optimal performance.
* Testing: Unit and integration tests are a priority. We aim to have a standard industry coverage of > 80% for the backend.
* CI/CD: We implement solid delivery pipelines and Secret Managers on AWS to ensure proper access to the credentials.
* Infrastructure as Code: Infrastructure as Code (IaC) helps us maintain better versioning of cloud resources and easily replicate environments.

These components ensure that Silencioʼs backend can handle increasing demand while safeguarding data and maintaining operational stability.
