QuantiSA: Quantified Service Architecture
Anand Shankar, Mangala Prasad Mishra · 2025
Microservices architecture has acquired significant popularity in modern application development because of its emphasis on independence, scalability, robustness, agility, and faster deployment cycles. This architectural style contrasts with the traditional monolithic architecture, where applications were built as single, indivisible units. The monolithic approach simplifies development and deployment, but at the same time, they become cumbersome when planning to scale. Deployment of new changes and technology integrations are also very challenging. Microservices addressed these limitations by way of designing the applications in such a way that applications are loosely coupled to each other and deployable independently to serve specific business needs. This approach enhances scalability, maintainability, and development speed. However, Microservices also introduced its own set of challenges. This paper explores the fundamental principles, advantages, and challenges of both monolithic and microservices architectures. Further, it proposes a novel architecture named as QuantiSA (Quantified Service Architecture), which aims to combine the strengths of both monolithic and Microservices architectures. QuantiSA is designed to meet the needs of large-scale enterprise applications, and will be discussed and compared in context of its performance, cost of development, delivery, infrastructure, maintenance, scalability, and security implementation.
