The main idea is to provide the ability for clients to integrate with our API and integrate with theirs. More than 7 micro-services, each dedicated to do its job. One service - External API was used to expose to the outside world our API that uses all the latest standards. The service had its ACL that gave us the ability to provide flexible access to any specific resources for any client on our side. Feed Manager was loading data from our database based on different criteria, converting data into a client's specific format and pushing either to our S3 bucket or to client's FTP. Another service - Supply Manager was used to integrate with clients' API and import their data into our database (ETL).
