In today’s digitally driven world, many small to medium Scale Enterprises (SMEs) find it difficult to manage or scale businesses due impediments in procuring and managing digital and software services. Many SMEs are unable to purchase the off-the-shelf software, as they are not tailor-made for their specific business use-cases and at times may not even fulfill the requirements. Creating custom software applications is an expensive undertaking and is difficult to maintain and scale. Further, the cost of deployment of these applications and ensuring availability either on premises or on cloud becomes a major hurdle. To overcome these hindrances, in this paper we propose the use of function-as-a-service technology in comparison to other options like micro-services and Service Oriented Architecture (SOA) and have highlighted the benefits in terms of ease of development and managing further we have put forth some economic benefits they have. FaaS can prove to be a major game changer service as it follows the model of pay-as-you-use and at idle time it can even scale to zero usage. This paper mainly discusses the option of using FaaS to help SMEs scale their application while cutting down on initial cost as well as economic impact in long run as compared to the other more traditional digital software service delivery models such as SaaS, ERP and custom application development.
