The adoption of microservices architecture has brought significant advancements in building scalable and flexible software systems. However, comprehending the performance impact of this architectural style is paramount for achieving high-performing applications. This study aims to investigate and assess how the microservices architecture affects the performance, with a particular emphasis on vital elements like inter-service communication, service discovery, data management, fault tolerance and scalability. This paper explores the variables driving performance and provides practical insights to improve performance in microservices-based systems through an exhaustive assessment of the literature and industry best practices. The findings contribute to a comprehensive understanding of performance considerations in microservices, empowering architects and developers with practical recommendations to optimize the performance of their applications.
