Challenge: Services and APIs for a scable user interface
(lively music) - [Instructor] In this challenge, we're going to look at how we actually get data into our database. Now, the health monitoring app will be sending geolocation data at regular intervals. Let's say every minute. Now, some things we want to consider are the size of the payload. In this case, it'll be about one to two kilobytes. And there may be tens of thousands of app instances actually running and sending data at any point in time. Also, keep in mind that data may arrive out of order. So now that challenge is to describe an architecture for an ingestion system that will scale and get this data into a relational database.
