The AWS Serverless URL is the API Gateway URL where the Lambda function is exposed. Navigate to AWS CloudFormation and select the stack name you just deployed. If not, you can manually do this from the AWS Explorer (that is part of the AWS Toolkit), available from View → AWS Explorer. Once complete, it automatically opens the CloudFormation Stack view within Visual Studio. It also requires the Stack Name as a parameter, to which all the resources are deployed. The CloudFormation settings take this as a parameter. In real-life projects, I set up a build deploy pipeline to automate this, which we will see in a different post.ĬloudFormation first uploads the package to deploy and the template to an S3 bucket and then deploys the application resources from there. It prompts up a dialog to choose the AWS profile, region, and CloudFormation settings. The easiest way to publish the AWS Lambda function to AWS infrastructure is to right-click on the project and select the ‘Publish To AWS Lambda…’ option.

To add another Lambda function, we need to create a new function endpoint in the code and add another resource in the serverless.template file. The function takes in an APIGatewayProxyResponse and returns APIGatewayProxyResponse since API Gateway triggers it. The Transform element in the template file indicates this file to contain AWS SAM syntax, which will be transformed into AWS CloudFormation compliant format. It can contain different sections of which Transform and Resources sections are required. The serverless.template file is used to define the Serverless Application. You manage resources by basically managing stacks. It has a well-defined structure and schema defined.Ī group of related resources forms a single unit called a Stack. Templates are YAML or JSON files that act as blueprints for building AWS resources. When using CloudFormation, you normally work with Templates and Stacks. AWS CloudFormationĪWS CloudFormation simplifies Infrastructure management, quickly replicate infrastructure and easily control and track infrastructure changes.ĪWS CloudFormation is a service that helps you model and set up your Amazon Web Services resources so that you can spend less time managing those resources and more time focusing on your applications that run in AWS.

Select the ’ Empty Serverless Application’ blueprint to create a Serverless application with just one function.Īs shown below, it contains the same set of files as we saw in the previous post on getting started with AWS Lambda with the addition of one new file serverless.template which is the AWS SAM template file. To create a new application, choose the ’ AWS Serverless Application (.NET Core - C#)’ option from the template list when creating a new project. The AWS Toolkit for Visual Studio comes with a built-in template to create a Serverless Application. We will see how we can deploy one or more Lambda functions using the AWS SAM and also use it to deploy a Lambda-driven API Gateway application backed by a DynamoDB database.
