Cloud Architecture for 99.99% Uptime Delivery

This technical report outlines the architectural framework of Beyond Identity's cloud service, which is designed to achieve a 99.99% uptime Service Level Objective (SLO). The document details how the service is built on the principles of Reliability, Availability, and Scalability (RAS) and is entirely cloud-native, utilizing Amazon Web Services (AWS) infrastructure. The architecture is characterized by a globally distributed, multi-tiered, and auto-scaling setup that minimizes network latencies and ensures redundancy through isolated Amazon Availability Zones. Each critical component operates independently, allowing for seamless failover and high reliability. The report also describes the operational monitoring processes in place, detailing the role of the Site Reliability and Engineering (SRE) team in maintaining service performance. Additionally, it lists specific AWS services employed to meet RAS goals, such as Amazon Route 53 and Amazon Aurora Global Database, which contribute to minimizing latency and ensuring application availability.
