Deploying AWS SAM Applications to API Gateway
Snowpal Podcast: Deploying an API gateway requires careful management of usage reporting. CloudFront may reject certificates that are otherwise valid.
In this conversation, Krish Palaniappan discusses the intricacies of deploying an API gateway on AWS, focusing on the management of API usage, reporting, and the challenges faced with certificate management. He elaborates on the deployment strategies across different environments, the debugging process for certificate issues, and the importance of understanding endpoint types and SSL certificates. The conversation also highlights the resolution of certificate chain issues and the necessary code adjustments to ensure smooth operation. In this conversation, Krish Palaniappan discusses the intricacies of optimizing AWS Lambda layers, the transition from AWS SDK version 2 to version 3, and the importance of efficient deployment strategies. He emphasizes the need for local development and testing using Express to enhance productivity and streamline the onboarding process for customers, including API key management and usage plans.
Takeaways
Deploying an API gateway requires careful management of usage reporting.
AWS requires timely reporting of API usage for payment processing.
Different environments (dev, staging, production) must be managed separately.
Template management is crucial for successful deployments.
Debugging certificate issues can be complex and time-consuming.
Certificates must be valid and recognized by AWS services.
CloudFront may reject certificates that are otherwise valid.
The certificate chain is essential for certain AWS services.
A reproducible test case is vital for debugging.
Code adjustments may be necessary when AWS updates SDKs. We have layers for each of our lambdas and sometimes multiple layers.
If the zip file is over a certain size, you're expected to put that on S3.
With SDK version 3, you do not import the entire AWS SDK.
We added a facade, a node and express app that we can call without deploying.
We generate the API key and include the product code for subscriptions.
The API key is validated by AWS when requests are made.
Onboarding the customer is crucial for API key generation.
API keys across environments show up in one place, which can be cumbersome.
Usage plans are created dynamically for new subscribers.
A fair summary includes all pieces for deploying apps on AWS.
