Architectural Design and Scalability: A Hybrid Approach with Kotlin, Mongodb And PostgreSQL

Abstract This research paper has been based on the topic: Architecture Design and Scalability - A hybrid approach with Kotlin, MongoDB, and PostgreSQL, for a modern web service. This research paper has discussed the importance of architectural design and scalability, and how it builds up a system and helps it stay reliable and is able to grow. This maintains its costs and the speed of the system. There has been an analysis of three very important components or approaches: Kotlin, MongoDB and PostgreSQL that are often used in developing software. They act as some of the best tools for resolving any commonly occurring challenges in the development of modern applications.
