Hystrix: it's the genus name for "Old World" porcupines, and it's also the latest release from Netflix. But you won't see it in their catalog of movie and TV titles, and you can't add it to your queue, because it's not content--it's how Netflix makes sure its content is highly available. Now, Netflix has made Hystrix open source, for anyone using Amazon Web Services (AWS) to implement in their own cloud applications. Read on for details on this "resilience engineering" code library.
At first, the phrase "my API is my Product" seems misleading. An API is a way to deliver a product, rather than the product itself, right? The term designates a "set of programming instructions designed to access an app." Period. We're talking about a means, rather than an end. That's why there are so many different products relying on APIs: Twilio for phone, Mailjet for email, Google Maps for maps, etc.
