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, …
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 …

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 …

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.
