Amazon Serverless Application Repository FAQs

Page topics

General

Open all

Serverless applications eliminate the need to provision, deploy, or manage servers or other infrastructure. They come with built-in high availability and they scale continuously and automatically. You can use one of the many fully managed  Amazon Web Services services to build and run serverless applications, including Amazon Lambda for compute, Amazon API Gateway for APIs, and Amazon DynamoDB for databases.

The Amazon Serverless Application Repository offers a growing collection of serverless applications published by  Amazon Web Services and other  Amazon Web Services partners and developers. The Serverless Application Repository makes it easy to deploy applications for common use cases like web and mobile back-ends, stream processing, machine learning, and more, so you can quickly get started with the  Amazon Web Services Serverless platform.

It is currently available in the following regions:  Amazon Web Services China (Beijing) region, operated by Sinnet,  Amazon Web Services China (Ningxia) region, operated by NWCD, Asia Pacific (Mumbai, Singapore, Sydney, Tokyo, Hong Kong), Canada (Central), EU (Frankfurt, Ireland, London, Paris), South America (São Paulo), US West (N. California, Oregon), US East (N. Virginia, Ohio), Middle East (Bahrain), and  Amazon Web Services GovCloud regions.

The Amazon Serverless Application Repository includes applications for Alexa Skills, chatbots, data processing, IoT, real time stream processing, web and mobile back-ends, social media trend analysis, image resizing, and more from publishers on  Amazon Web Services.

There is no charge to browse applications, deploy applications, or publish applications in the  Amazon Serverless Application Repository. Standard  Amazon Web Services charges apply to the resources used by the applications you deploy.

Applications provided by Amazon Web Services are available under the MIT open source license, while applications publicly provided by others can be made available under one or more open source license(s) approved by the Open Source Initiative (OSI). You can find licensing details by navigating to the licensing tab of an application on the  Amazon Web Services website.

All applications published by  Amazon Web Services are vetted for license adherence and code quality. Applications published by third parties are validated for correct use of permissions to ensure that consumers know which resources can be modified or accessed by an application. You can review those details, along with the number of times an application has been deployed by  Amazon Web Services customers, prior to using an application.

Yes. The  Amazon Serverless Application Repository enables developers to publish serverless applications developed in a GitHub repository. Using Amazon CodePipeline (this is only available in global regions) to link a GitHub source with the Amazon Serverless Application Repository can make the publishing process even easier, and the process can be set up in minutes.

Deploying applications

Open all

Serverless applications are deployed as Amazon CloudFormation stacks, which make it easy for you to manage an application as a single unit. Each resource is tagged with the application’s uniquely identifiable Amazon Resource Name (ARN), which helps you locate the resources using the  Amazon Web Services Tag Editor console. You can also use existing  Amazon Web Services and third-party tools to manage each resource separately.

Publishing applications

Open all

To publish a serverless application, describe the application using the Amazon Serverless Application Model (SAM) format, package it using the Amazon CLI, and publish it using the  Amazon Web Services Management Console, Amazon CLI, or Amazon SDKs. You must have a valid  Amazon Web Services account, and you will be required to provide a name, description, source code link, and a LICENSE.txt for your application. Read more here .

Publishers control who can find and deploy their applications in the Repository. You can limit access to your team (a group under the same  Amazon Web Services account), share an application with other accounts, or make it publicly available to any  Amazon Web Services customer. To learn more about the permissions and visibility of applications you publish, review our Resource-Based Policies documentation .

If you would like to charge a fee for the use of a serverless application, you can integrate Amazon Lambda behind Amazon API Gateway, and then sell the API as a SaaS product through the Amazon Web Services Marketplace. To learn more, review the steps to list on  Amazon Web Services Marketplace and how to monetize your API using API Gateway.

Nested applications

Open all

A nested serverless application is a component that is deployed as part of another serverless application. As serverless architectures grow, common patterns emerge in which the same components are defined in multiple application templates. You can now separate out common patterns as dedicated applications and then nest them as part of new or existing application templates.

Nested applications are deployed as Amazon CloudFormation nested stacks.

Use the AWS:Serverless:Application resource type to add applications that you have developed locally or that have been shared with you via the Serverless Application Repository. You can define inputs for the nested application or reference outputs using simple  Amazon Web Services SAM syntax. For more details, see our documentation .

Specify a unique name for each nested application in your SAM template. Resources created by the nested application will be scoped to the application's unique name.

Use the SAM CLI sam package command to package your nested application. Publish your packaged application to the Serverless Application Repository using APIs or the Amazon SDK. You can use the SAM CLI sam deploy command to deploy your application immediately.

Yes. The SAM CLI sam package command will recursively package a hierarchy of nested applications. You can have a maximum of 199 applications nested in a single top-level application template.

Consuming nested applications

Open all

Serverless applications are deployed as Amazon CloudFormation stacks, which make it easy for you to manage an application as a single unit. Each resource is tagged with the application’s uniquely identifiable Amazon Resource Name (ARN), which helps you locate the resources using the  Amazon Web Services Tag Editor console. You can also use existing  Amazon Web Services and third-party tools to manage each resource separately.

Configure the AWS:Serverless:Application SAM resource with the application ARN and any necessary input parameters required by the application. For more details, see our documentation .

Nested applications from the Serverless Application Repository are already packaged and ready for you to use. You can use the existing SAM CLI sam package command to ensure that nested applications are still available to you before you deploy the application in your account.

Applications that you nest which get deleted or that you no longer have access to will have no impact on the existing deployments of your application. You will be required to update your application if you attempt to deploy it with dependencies that no longer exist.

Applications that contain one or more nested applications use CAPABILITY_AUTO_EXPAND.

Yes. You can publish nested applications to the Serverless Application Repository just like you publish stand-alone applications today. Use the  Amazon Web Services management console, Amazon CLI, SAM CLI, or Serverless Application Repository APIs to publish nested applications.

Serverless applications follow the same model used by Lambda functions today. Access to serverless applications in the Serverless Application Repository can be controlled using Amazon IAM resource-based policies. You can use policies to keep your application private, grant cross-account access, or make it publicly available.

With a hierarchy of nested applications, each nested application has to be made available to the  Amazon Web Services account with whom you are sharing the top-level application.
