This is part 2 of a multipart series that explores ideas on how we could apply the principles of chaos engineering to serverless architectures built around Lambda functions. part 1: how can we apply principles of chaos engineering to Lambda? part 2: latency injection for APIs <- you’re here part 3: fault injection for Lambda …

AWS announced binary support for API Gateway in late 2016, which opened up the door for you to use more efficient binary formats such as Google’s Protocol Buffers and Apache Thrift. Why? Compared to JSON – which is the bread and butter for APIs built with API Gateway and Lambda – these binary formats can produce significantly smaller payloads. At scale, …

Serverless architectures are microservices by default, you need correlation IDs to help debug issues that spans across multiple functions, and possibly different event source types – asynchronous, synchronous and streams. This is the last of a 3-part mini series on managing your AWS Lambda logs. If you haven’t read part 1 yet, please give it a read now. …

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 …

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 …

Since I started working at Yubl less than 2 weeks ago, I have been doing a lot of work with Amazon API Gateway & Lambda with the help of the Serverless framework. So far that experience has been really great. One little caveat I ran into was that, it wasn’t clear on how to enable caching …
