Using AWS Gateway + AWS Lambda allows to easily deploy and scale APIs. There are no servers to SSH into, install security updates or scale.
Pros:
- SSL termination is taken care by the AWS Gateway
- Supports multiple environments
- Supports versioning and rollbacks
- Operation cost is low
Cons:
- Cold starts can make the API slow (during scaling)
- 30 seconds HTTP request limit
- Cost may be larger when scaling up
We use The Serverless Framework
Build applications comprised of microservices that run in response to events, auto-scale for you, and only charge you when they run. This lowers the total cost of maintaining your apps, enabling you to build more logic, faster.
The serverless.yml file includes all the infrastructure definitions to create a full API server as a single Lambda function and creates an API Gateway that routes requests to it.
Everything happens on our AWS account and our CI tool uses it to deploy the API server on each successful commit to master.
