Microservices architecture for an e-commerce platform

Boris Stoyanov-Brignoli
After a few years of working on technical issues related to e-commerce, I suggest here to explore what I believe to be a list of services that can make up an e-com platform. I deliberately chose to remain concise and to focus on UX. What impact for the customer? Normally, if you implement these various components, your business should run smoothly ;)
