Micro services-Based Architectures: A Pathway to Achieving Fault Tolerance in Distributed Systems

Abstract

Driven by the demand for scalable, robust, and decentralized systems, this article explores novel trends in micro 
service development, highlighting the shift from monolithic architectures to micro services. It examines how 
developments in cloud computing and containerization have enabled the shift from Service-Oriented 
Architecture (SOA) to micro services. The paper examines important patterns that improve data integrity, 
scalability, and communication in micro services, including the Saga pattern, event-driven architecture, and 
service mesh. Small, independent services that communicate via well-defined APIs form MSA, which has many 
benefits over conventional monolithic designs, including increased scalability, maintainability, and agility. In 
addition to highlighting how industry titans like Amazon and Netflix have embraced MSA, the paper charts the 
development of MSA from Service-Oriented Architecture (SOA).
