海外TECH	DEV Community	Use AWS App Runner, DynamoDB and CDK to deploy and run a Cloud native Go app	https://dev.to/abhirockzz/use-aws-app-runner-dynamodb-and-cdk-to-deploy-and-run-a-cloud-native-go-app-3705	Use AWS App Runner DynamoDB and CDK to deploy and run a Cloud native Go appEarlier I wrote about a Serverless URL shortener application on AWS using DynamoDB AWS Lambda and API Gateway Build a Serverless URL shortener with Go Abhishek Gupta for AWS・Aug ・ min read serverless tutorial go database In this blog post we will deploy that as a REST API on AWS App Runner and continue to use DynamoDB as the database AWS App Runner is a compute service that makes it easy to deploy applications from a container image or source code manage their scalability deployment pipelines and more With the help of a practical example presented in this blog you will Learn about AWS App Runner how to integrate it with DynamoDBRun simple benchmarks to explore the scalability characteristics of your App Runner service as well as DynamoDBApply Infrastructure as Code with AWS CDK Go and deploy the entire stack including the database application and other AWS resources Also see the DynamoDB Go SDK v in action and some of the basic operations such as PutItem GetItem Let s start by deploying the URL shortener applicationBefore you begin make sure you have the Go programming language v or higher and AWS CDK installed Clone the project and change to the right directory git clone cd cdkTo start the deployment Run cdk deploy and provide your confirmation to proceed The subsequent sections will provide a walk through of the CDK code for you to better understand what s going on cdk deployThis will start creating the AWS resources required for our application If you want to see the AWS CloudFormation template which will be used behind the scenes run cdk synth and check the cdk out folderYou can keep track of the progress in the terminal or navigate to AWS console CloudFormation gt Stacks gt DynamoDBAppRunnerStackOnce all the resources are created you should have the DynamoDB table the App Runner Service along with the related IAM roles etc URL shortener service on App RunnerYou should see the landing page of the App Runner service that was just deployed Also look at the Service Settings under Configuration which shows the environment variables configured at runtime by CDK as well as the compute resources VCPU and GB that we specified Our URL shortener is ready The application is relatively simple and exposes two endpoints To create a short link for a URLAccess the original URL via the short linkTo try out the application you need to get the endpoint URL provider by the App Runner service It s available in the stack output in the terminal or the Outputs tab in the AWS CloudFormation console for your Stack First export the App Runner service endpoint as an environment variable export APP URL lt enter App Runner service URL gt exampleexport APP URL Invoke it with a URL that you want to access via a short link curl i X POST d APP URL outputHTTP OKDate Thu Jul GMTContent Length Content Type text plain charset utf ShortCode aeea You should get a JSON response with a short code and see an item in the DynamoDB table as well You can continue to test the application with a few other URLs To access the URL associated with the short code enter the following in your browser http lt enter APP URL gt lt shortcode gt For example when you enter you will be re directed to the original URL You can also use curl Here is an example export APP URL curl i APP URL aeea outputHTTP FoundLocation Date Thu Jul GMTContent Length Auto scaling in actionBoth App Runner and DynamoDB are capable of scaling up and down according to workload AWS App RunnerAWS App Runner automatically scales up the number of instances in response to an increase in traffic and scales them back when the traffic decreases This is based on AutoScalingConfiguration which is driven by the following user defined properties Max concurrency Max size and Min size For details refer to Managing App Runner automatic scalingHere is the auto scale configuration for the URL shortener App Runner Service DynamoDBIn case of On demand mode DynamoDB instantly accommodates your workloads as they ramp up or down to any previously reached traffic level Provisioned mode requires us to specify the number of reads and writes per second that you require for your application but you can use auto scaling to adjust your table s provisioned capacity automatically in response to traffic changes Lets run some testsWe can run a simple benchmarks and witness how our service reacts I will be using a load testing tool called hey but you can also do use Apache Bench etc Here is what we ll do Start off with a simple test and examine the response Ramp up the load such that it breaches the provisioned capacity for the DynamoDB table Update the DynamoDB table capacity and repeat Install hey and execute a basic test requests with workers concurrently as per default settings hey APP URL lt enter the short code gt examplehey This should be well within the capacity of our stack Let s bump it to concurrent workers to execute requests for a sustained period of minutes hey c z m APP URL lt enter the short code gt examplehey c z m How is DynamoDB doing In DynamoDB console under Table capacity metrics check Read usage average units second More importantly check Read throttled events count Since our table was in Provisioned capacity mode with RCU and WCU the requests got throttled and some of them failed Edit the table to change its mode to On demand re run the load test You should not see throttling errors now since DynamoDB will auto scale in response to the load What about App Runner In the Metrics seton in App Runner console check the Active Instances count You can also track the other metrics and experiment with various load capacitiesAlright now that you ve actually seen what the application does and examined the basic scalability characteristics of the stack let s move on to the how But before that Don t forget to delete resourcesOnce you re done to delete all the services simply use cdk destroy AWS CDK code walk through We will go through the keys parts of the NewDynamoDBAppRunnerStack function which defines the entire stack required by the URL shortener application I ve omitted some code for brevity You can refer to the complete code on GitHubWe start by defining a DynamoDB table with shorturl as the Partition key Range Sort key is not required for our case Note that the BillingMode attribute decides the table capacity mode which is Provisioned in this case with RCU and WCU As demonstrated in the previous section this was chosen on purpose func NewDynamoDBAppRunnerStack scope constructs Construct id string props DynamoDBAppRunnerStackProps

RemovalPolicy DESTROY Then we use awsiam NewRole to define a new IAM role and also add a policy that allows App Runner to execute actions in DynamoDB In this case we provide granular permissions

stack jsii String app image amp awsecrassets DockerImageAssetProps Directory jsii String appDirectory Once all the pieces ready we define the App Runner Service Notice how it references the information required by the application The name of the DynamoDB table defined previously is seeded as TABLE NAME env var required by the application The Docker image that we defined is directly used by the Asset attributeThe IAM role that we defined is attached to the App Runner service as Instance RoleThe instance role is an optional role that App Runner uses to provide permissions to AWS service actions that your service s compute instances need Note that that an alpha version at the time of writing of the L App Runner CDK construct has been used and this is much simple compared to the CloudFormation based L construct It offers a convenient NewService function with which you can define the App Runner Service including the source locally available in this case the IAM roles

RemovalPolicy DESTROY Wrap upThis brings us to the end of this blog post You explored a URL shortener application that exposed REST APIs used DynamoDB as its persistent store and deployed it to AWS App Runner Then we looked at how the individual services scaled elastically in response to the workload Finally we also explored the AWS CDK code that made is possible to define the application and its infrastructure as Go code Happy building	2022-08-17 03:06:00
