In this session, we will discuss how the AWS Serverless Application Repository makes it easy to discover and deploy serverless applications published by fellow developers and companies like Datadog, Here, Splunk, and many others. We will cover how you can use the repository to find applications for a variety of use cases and then deploy them to your AWS account. In addition, we will discuss how you can publish your own applications to the repository. You will also hear from two contributors, Datadog and Here, who will describe their approach to building the serverless applications that they have published to the Serverless Application Repository.

CUSTOMER LEARNINGS – BLUERPINTS
• AWS only. Not open to third parties.
• Functions only. No other resources.
• Limited selection, limited language choice.
• Not linked to GitHub or AWS CodeCommit. No easy update.

CUSTOMER LEARNING
Many serverless examples are shared on GitHub.
Limitations of GitHub:
• Discovery: How to find the right “serverless” apps.
• Provenance. Can developers be sure of the source?
• Bring your own build (BYOB): Developers have to recreate
the build environment, adding friction.
• Not connected to the authoring workflow for Lambda
functions.

To package your application, create an Amazon S3 bucket that the package
command will use to upload your ZIP deployment package.
aws s3 mb s3://bucket-name --region region
aws cloudformation package
--template-file example.yaml
--output-template-file serverless-output.yaml
--s3-bucket s3-bucket-name
The package command returns an AWS SAM template. This template
represents your serverless application that you can submit.

WE LOVE AWS LAMBDA, BUT…
It is cumbersome for customers to copy and paste code
and set up Lambda permission policies.
It is a challenge to update Lambda functions.

ENTER THE AWS SERVERLESS REPOSITORY
Setting up these functions is as easy as downloading an
app.
Updates to the functions will be seamless and enable
customers to have the newest functionality.
