At Yubl, we arrived at a non-trivial serverless architecture where Lambda and Kinesis became a prominent feature of this architecture. Whilst our experience using Lambda with Kinesis was great in general, there was a couple of lessons that we had to learn along the way. Here are 3 useful tips to help you avoid some …

An interesting requirement came up at work this week where we discussed potentially having to run our own URL Shortener because the Universal Links mechanism (in iOS 9 and above) requires a JSON manifest at https://domain.com/apple-app-site-association Since the OS doesn’t follow redirects this manifest has to be hosted on the URL shortener’s root domain. Owing to a limitation on AppsFlyer it’s …

Hello, just a quick note to say thanks to everyone who attended the AWS user group meetup last night, was a pleasure to talk to many of you afterwards. As promised, here are the slides for my talk from last night. AWS Lambda from the trenches from Yan Cui
As Lambda adds nodejs 6.10 to its supported platforms I wondered if there’s any performance differences between the platforms. Thankfully the templates in the Serverless framework make it a relative breeze to test it out with a simple HelloWorld function. The Test see the test code here. I created a simple Lambda function for each platform that will …
part 1: overview part 2: testing and CI/CD part 3: ops <- you’re here part 4: building a scalable notification system part 5: building a better recommendation system A couple of folks asked me about our strategy for monitoring, logging, etc. after part 2, and having watched Chris Swan talk about “Serverless Operations is not a …
part 1: overview part 2: testing and CI/CD <- you’re here part 3: ops part 4: building a scalable notification system part 5: building a better recommendation system Having spoken to quite a few people about using AWS Lambda in production, testing and CI/CD are always high up the list of questions, so I’d like to use …

Read the whole series: Part 1 — type inference Part 2 — traits Part 3 — case class/object (ADTs) Part 4 — apply & unapply functions <- you’re here Part 5 — implicits Last time around we looked at Scala’s Case Class in depth and how it compares to F#’s Discriminated Unions. F# also has Active Patterns, which is a very powerful language …
