The pains and gains of microservices: A Systematic grey literature review

The design, development, and operation of microservices are picking up more and more momentum in the IT industry. At the same time, academic work on the topic is at an early stage, and still on the way to distilling the actual Pains & Gains of microservices as an architectural style. Having witnessed this gap, we set forth to systematically analyze the industrial grey literature on microservices, to identify the technical/operational pains and gains of the microservice-based architectural style. We conclude by discussing research directions stemming out from our analysis. (C) 2018 Elsevier Inc. All rights reserved.
