AWS Lambda – build yourself a URL shortener in 2 hours

API Gateway, AWS, DynamoDB, Lambda, Programming, Serverless

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 …

AWS Lambda – comparing platform performances

AWS, Lambda, Programming

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 …

AWS Lambda – janitor-lambda function to clean up old deployment packages

AWS, Lambda, Node.js, Programming, Serverless

When working with AWS Lambda, one of the things to keep in mind is that there’s a per region limit of 75GB total size for all deployment packages. Whilst that sounds a lot at first glance, our small team of server engineers managed to rack up nearly 20GB of deployment packages in just over 3 months! Whilst …
