The document discusses the benefits and functionalities of AWS Lambda and Amazon API Gateway in a serverless architecture, emphasizing their rapid deployment capabilities and event-driven nature. It covers AWS Lambda's support for various programming languages, API Gateway's features for building and managing APIs, and integration options with other AWS services. Additionally, it mentions the use of Amazon S3 and CloudFront for hosting and delivering static websites.

can upload your code and it
runs the it on your behalf using
AWS infrastructure.

and endpoint using Amazon
API Gateway
HTTPS only

Languages

14. AWS
Lambda
Console for simple implementations
with no external dependencies.
or
Zip file with your code and
dependencies. Upload directly or use
S3
Deployment package

15. AWS
Lambda
Only local state, and is limited to the
current Lambda execution
Stateless

16. Amazon
API Gateway
A scalable, fully-managed
service to publish, maintain,
monitor, and secure APIs.

17. Amazon
API Gateway
Each resource within a REST API can
support one or more of the
standard HTTP methods
Define verbs supported for each
resource (GET, POST, PUT, PATCH,
DELETE, HEAD, OPTIONS) and their
implementations
RESTful

18. Amazon
API Gateway
Built in staging
multiple stages (e.g. dev, test, deploy)
Built-in versioning
multiple versions simultaneously
Staging & versioning

19. Amazon
API Gateway
Works with Lambda or your own
publicly accessible endpoints
Lambda- or custom-backed

20. Amazon
API Gateway
Custom authorisers, e.g. JWT, OAuth
Cognito integration
Authorisation & Authentication

21. Amazon
API Gateway
Allows resources on a web page to be
requested from another domain outside the
domain from which the resource originated,
e.g. calls to API Gateway endpoints
CORS support

22. Amazon
API Gateway
Android, iOS, or JavaScript boilerplate
SDK code generation

23. GET https://romanapi.com/v1/numeral/MCMLXIX
{
