Having previously blogged about the untrodden path to enable caching on API Gateway request parameters in the Serverless framework 0.5.X, it’s a little disappointing that it’s still not officially fixed in the 1.X versions… The Problem The problem is two-fold: there’s currently no way to specify caching should be enabled for path & query string …

part 1: overview part 2: testing and CI/CD part 3: ops part 4: building a scalable notification system <- you’re here part 5: building a better recommendation system Just before Yubl’s untimely demise we did an interesting piece of work to redesign the system for sending targeted push notifications to our users to improve retention. The …

Following on from the last post where we discussed 3 useful tips for working effectively with Lambda and Kinesis, let’s look at how you can use Lambda to help you auto scale Kinesis streams. Auto-scaling for DynamoDB and Kinesis are two of the most frequently requested features for AWS, as I write this post I’m sure the folks …
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 …
