1TRANSFORMATION FROM MONOLITHIC TO MICROSERVICES
Executive Summary
The monolithic systems of the business processes incorporates imminent challenges while
developing codes or rebuilding new versions of the system. Hence, a new technological
innovation of microservices architecture is facilitating the organizations to segregate their
business activities into individual, self-sufficient software modules that will function on their
own, yet communicate with other systems to enhance smart business decisions.
Microservices architecture has various beneficial aspects such as optimality in services, easier
issue-handling features and so on; however, there are disadvantageous issues with ethical
situations, security hackings and legal issues too. This report will cover all aspects of
microservices architecture such that the CTO of the Whiteboard Company can adhere to it
before implementing the microservices architectural design in their educational management
system.

Introduction
The architecture of microservices refers to the breakdown of the distinct systems in a
business process to ensure that each system works independently in spite of being connected
through simplest API’s for communicational purpose. Each of the systems are responsible of
carrying out different services and hence are developed individualistically, after which they
are integrated through API such that they can interact with each other and thereby build up an
integrated module of the business (Cerny, Donahoo & Trnka, 2018). The success behind
some high-profile organizations such as Netflix, Uber and many similar infrastructures is
their decision to shift from monolithic services to microservices such that they can pace up
their business processes with self-functioning modules, while maintaining a cohesive
approach amongst the modules operating in the business.
One of the most advantageous features of microservices architecture is that, since the
modules operate independently, hence they are built on different platforms and the coding of
the distinct systems are not integrated with each other. This allows the developers of each
individual system to attend issues separately for the system having the issue without
disturbing the other systems of the business (Granchelli et al., 2017). Modifying the codes of
one system or upgrading them for user-friendly features will not affect the functionalities of
the other system and bring the process to a halt. Apart from this, microservices architecture,
unlike monolithic services, incorporates the usage of the different programming languages or
databases that will be suitable for the systems to operate, with only one condition to fulfil that
they are compatible with the API versions (Nadareishvili et al., 2016). Thus, this paper will
highlight different aspects of microservices architecture and the elaborate the reason behind
its popularity in the current business companies.
