Ressy is real time capacity management platform for services business. It allows merchants (restaurant owners) to push on demand discount deals to the users in real time and users can avail with their smart phones Choosing the technology stack was crucial for us, specifically considering the domain of the app. Food tech is the hottest industry in India, and user adoption is quite rapid for these kinds of apps. Having minimum lags, fastest content delivery, ~100% uptime were the important facets of the backend technology. Golang being the most popular inside Betacraft, we thought, Golang based API server is going to be apt for this domain. We were right, we wrote the entire backend for User Application + Merchant Apps and a basic dashboard APIs in a month. We have attached the HTTP response time graph for Ressy API server, measured on NewRelic. The max mean API response time is 170 ms . This is using a micro instance on AWS (which costs $0.02 per Hour for on demand instance).
