Having taught thousands of students to build serverless applications via my online courses and workshops, I felt it was time to kick-start an affiliate program to boost sales. Affiliates would receive 50% of the revenue and get a 15% discount code for their audience. It feels like a good deal but I would need a …

I previously wrote about five reasons you should consider AppSync over API Gateway. One thing that API Gateway supports but you can’t do with AppSync out-of-the-box yet is custom domain names. Your shiny new AppSync API is available at XYZ.appsync-api.us-east-1.amazonaws.com/graphql, but you really want people to use your own domain instead because dev.example.com/graphql is much …
Update 21/06/2020: following lots of feedback and questions on Twitter, I have updated the post to include a few more options. Quite a few clients have asked me “Hey Yan, what API Gateway auth method should I use for this REST API?” so I thought I’d share my answer with everyone here. This is the …
So you have built a serverless application, that, amongst other things, lets you upload images and files to S3. The setup is very simple: API Gateway, Lambda and S3. It took you no time to implement and it works like a dream. You pat yourself on the back for another job well done. One day, …

Disclaimer: this is a long list, you don’t need to tick every box to go-live. Think of them as a ladder, the more critical a system the higher you should try and climb. Observability Enable detailed monitoring to get per-method metrics (e.g. latency for GET /index). Without this, CloudWatch only reports aggregated metrics for all …

When you deploy an API to API Gateway, throttling is enabled by default in the stage configurations. By default, every method inherits its throttling settings from the stage. Having built-in throttling enabled by default is great. However, the default method limits – 10k req/s with a burst of 5000 concurrent requests – matches your account …

Last week, someone asked me at the AWS User Group in The Hague “Is caching still relevant for serverless applications?” The assumption here is that Lambda auto-scales by traffic, so do we still need to worry about caching? And if so, where and how do we implement caching? So let’s break it down. Caching is …

Update 17/09/2019: based on feedback, I added a few more alternatives that do not require you to deploy additional Lambda functions to the e2e-test stage. Scroll to the end to find out more. Being event-driven is a key characteristic of a serverless architecture. Often our Lambda functions would publish events to SNS topics or Kinesis …

At DAZN (where I no longer work), the teams work with a number of third-party providers. They often have to synchronize data between different AWS accounts. SNS to SQS is the primary mechanism for these cross-account deliveries because: it was an established pattern within the organization DAZN engineers and third-party engineers are both familiar with …

If you haven’t been paying close attention you might have missed the API Gateway announcement for resource policies. It later played a key role in supporting API Gateway private endpoints – a way to put your API inside a private VPC. To configure resource policies with the Serverless framework, you need to upgrade to v1.28.0 or …
