Scalable micro-service based approach to FHIR server with golang and No-SQL

Fast Health Interoperability Resource (FHIR) for Electronic Health Record (EHR) not only opens a new era for health-care systems to exchange data between themselves but also allows other various systems following the same framework to communicate between them. FHIR is engaging and evolving rapidly and it is creating the need of massive data storage, retrieval and transfer requirements. For a server that implements this framework, has to be agile to cope with the growing and massive data handling. E-health-care data also seem to grow proportional to time. So, an ideal FHIR Server has to be scalable to fit this demand over time. Several different tools could help store, anonymize, analyze and extract data because there are no single tools to get all those things done. In this work, we propose a scalable, agile, and reliable Micro-service based Architecture for FHIR server that is highly available with the help of Document Oriented Database and helps to store health-care data. The proposed architecture is fast responsive. It gives our system the flexibility to use different tools that implement FHIR Framework interface in such way that the whole system could be made vertically scalable and the system can perform better in terms of time complexity compared to a Monolithic based implementation of the framework. Experimental results show that the proposed model can be highly used as an alternative to currently available FHIR system implementation.
