#ScalibilitySherpa.com ##How to create a GO Microservice in 7 days
##Problem Scalabilitysherpa.com is expanding its footprint and they need a robust infrastructure. Currently the website is serving videos using a tightly coupled MERN stack. The company would like a more modern approach to persist data.
-
Users- The website needs to track each individual users progress throughout the website, if they are paid or free content only.
-
Videos - Videos should contain a title, location of links , number of views.
-
Operational restrictions: The database needs to be secure, backups need to be provided as part of this service infrastructure change.
-
Login should be handled by a third party oath
##Current Infrastructure Tightly coupled react framework with MYSQL backend.
