Microservices and Big Data are renowned hot topics in computer science that have gained a lot of hype. While the use of microservices is an approach that is used in modern software development to increase flexibility, Big Data allows organizations to turn today’s information deluge into valuable insights. Many of those Big Data architectures have rather monolithic elements. However, a new trend arises in which monolithic architectures are replaced with more modularized ones, such as microservices. This transformation provides the benefits from microservices such as modularity, evolutionary design and extensibility while maintaining the old monolithic product’s functionality. This is also valid for Big Data architectures. To facilitate the success of this transformation, there are certain beneficial factors. In this paper, those aspects will be presented and the transformation of an exemplary Big Data architecture with somewhat monolithic elements into a microservice favoured one is outlined.

The objective of this study is to analyse the perception and awareness of the Expatriates and start-up businesses of the presence and value proposition of FinTech Services such as Payment/Banking, Lending and Crowdfunding in UAE. Data was collected using a survey-based questionnaire and respondents were chosen using convenient sampling method. Research design is a Cross-Sectional design. Data was collected between February to April 2020. The target audiences were Expats between the ages of 20-40 who have been living in UAE for at least 3 years. The level of awareness of most respondents in the FinTech services such a P2P lending; Robo Advising and Insurtech were fairly limited. The results discovered reflect a positive sign regarding the acceptance of these new FinTech services in UAE. From the findings, we can also notice that majority of the respondents are hoping for FinTech to be able to act as a secondary financing source apart from normal financing methods. And moreover, FinTech development in the UAE market could further increase business activities all throughout. Not many in depth studies on FinTech have been done across the world. In the context of UAE there were even lesser. This paper is one of its kinds in the region, which allows us to understand the awareness and perception of consumers towards technology and the financial industry using a broad spectrum of variables.

Due to the ever increasing amount of data that is produced and captured in today's world, the concept of big data has risen to prominence. However, implementing the respective applications is still a challenging task. This holds especially true, since a high degree of flexibility is desirable. One potential approach is the utilization of novel decentralized technologies, as in the case of microservices to construct such big data analytics solutions. To obtain an overview of the current situation regarding the corresponding research, using the scientific database Scopus and its provided tools for search and analytics, this bibliometric review provides an analysis of the literature and subsequently discusses avenues for future research.
