Evolution of Software Architecture over Decades

Through this paper, an attempt is made to portray the evolution of Software Architecture (SA) over a significant period of time with a perception of how Software Architecture revamped itself to meet the changing trends in IT Industry. Vital research activities are highlighted along with examples and streamlined addressing the architectural capabilities relevant to the industry 4.0 generation systems. The current generation software systems are getting rich in features and exhibit complex behavior. Representing these scenarios poses several challenges at the architectural level. To address these challenges, dynamic design decisions are recommended for creating SA.
