Access management can be a bit of a nightmare, especially when we realize that we rely on a number of different, independent services that power our organizations.

Mention concurrency and you’re bound to get two kinds of unsolicited advice: first that it’s a nightmarish problem which will melt your brain, and second that there’s a magical programming language or niche paradigm which will make all your problems disappear.

JavaScript promises have always been a major win for the language — they’ve led to a revolution of asynchronous coding that has vastly improved performance on the web.

It happens less frequently these days but there are times when we need to accommodate for a HTTP request timing out.

Maybe it was just a network glitch and it will work just fine when you try to call it again. Introducing retries is a relatively simple step that can improve the stability of your service. But before adding retries check if you’ll not…
