“Even simple serverless applications have complex architecture diagrams”, so what?

Let me tell you why this misses the point.

How to sample AppSync resolver logs
AppSync has built-in logging integration with CloudWatch Logs (see here for more details on the logging options). You can set the Field resolver log level to NONE, ERROR or ALL. When the field resolver log level is set to NONE or ERROR, you don’t get a lot of value from the AppSync logs. For example, …
How to set up custom domain names for AppSync
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 …

Choreography vs Orchestration in the land of serverless
Choreography and Orchestration are two modes of interaction in a microservices architecture. In orchestration, there is a controller (the ‘orchestrator’) that controls the interaction between services. It dictates the control flow of the business logic and is responsible for making sure that everything happens on cue. This follows the request-response paradigm. In choreography, every service …

How I scaled an AppSync project to 200+ resolvers
I have been working on a large AppSync project for a client these past few months. The initial version of the app was built in just a few weeks, but the client has commissioned additional features and the project has kept growing. At the time of writing, this project has over 200 AppSync resolvers and …

AppSync: how to inject table names into DynamoDB batch & transact operations
When working with CloudFormation, AWS recommends not to give explicit names to resources and let CloudFormation name them for you. This has several advantages: It’s harder for attackers to guess resource names such as S3 buckets or DynamoDB tables. You can deploy the same stack multiple times to the same account. This is useful when …
