Deepak Nanuru Yagamurthy, Rekha Sivakolundhu

Abstract: This paper deep dives into the multifaceted analysis faced by engineering organizations when choosing between self-hosting vendor software and embracing Software-as-a-Service (SaaS) cloud solutions. Beyond security and audit analysis, we explore the intricate interplay of factors that influence this choice, including cost, control, scalability, customization, vendor support, and alignment with organizational goals. Through a comprehensive comparative analysis, we examine the strengths and weaknesses of each model, providing a holistic view to guide informed decision-making. Our research highlights the importance of considering a diverse range of factors beyond security, emphasizing the need for a tailored approach that aligns with an organization's unique needs and priorities.
