Building Scalable Web Applications: Best Practices for Backend Architecture

Bangar Raju Cherukuri

Abstract: Suppose only large-scale web applications are to be developed. In that case, the architecture of the back end has to be scalable to support heavier volumes of users, data requests, and performance expected on the web. This paper will discuss how to create and deploy highly available backends with the help of microservices architecture, which allows split services to become more independent and efficient. This is done through the use of APIs for the interaction between services, which makes the entire system modulable and quite flexible, allowing for growth within web applications to be accommodated. In addition, the various measures used in database management, such as indexing, caching, and horizontal scaling, are important in ensuring that the database is capable of processing a large number of transactions. Altogether, the architectural approaches to building web applications facilitate application growth while making the process immune to overcrowding if considered as a single whole.
