This research aims to design and develop a Software-as-a-Service (SaaS) queueing backend capable of handling massive surges in web demand. Many current websites lack the capability to manage significant spikes in demand, often leading to system failures. Therefore, an effective solution is needed to manage user surges and ensure that the system remains stable and responsive. In this study, two backend designs were developed based on business capabilities and domain-driven patterns. Both approaches use a microservice architecture that allows each service to be scaled and updated independently, thus enhancing the system’s ability to withstand high loads. The implementation process includes design, development, and performance and security testing to ensure that the system meets the expected requirements. Testing results show that the SaaS queueing backend application designed with a domain-driven pattern is more effective in handling demand surges compared to the business capabilities pattern. This system not only successfully prevents system failures by accommodating and channeling requests according to capacity but also enhances security against cyber threats. Thus, this research demonstrates that implementing microservice architecture with a domain-driven approach is an optimal solution for managing demand surges in SaaS queueing systems, making it a reliable choice for developing web applications that require high scalability and resilience.
