Backend Our backend is hosted on Amazon Web Services, a market leader in Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) (AWS). Our backend services are implemented utilizing AWS Lambda in a serverless manner. This allows us to provide essentially limitless scalability while yet keeping a cost-effective solution. Our major persistence method is DynamoDB, which enables us to deliver an atomic, consistent, isolated, durable, and highly available solution via the use of transactional features. We employ the whole suite of AWS monitoring and security services, including CloudWatch, GuardDuty, Inspector, Detective, and Security Hub, on the back end.
