Trends indicate that the number of apps that rely on HTTP based APIs has been growing. Many players routinely serve several billion requests a day to apps that use HTTP APIs as a back-end. Though it is not trivial to scale up the servers, it is time to take a look at the client side which has just two needs - how to make sense of data from multiple APIs, and how to optimize the traffic to minimize latency, reduce bandwidth use, and
improve resiliency. In this talk, we will take a consuming app's perspective, and dive into how to bridge interoperability and address performance goals. We will use ql.io, an open-source node.js based HTTP gateway, as a way to demonstrate potential approaches.
