Step 1: Create a Lambda function to iterate a count By using a Lambda function you can track the number of iterations of a loop in your state machine. The following Lambda function receives input values forcount,index, andstep. It returns these values with an updatedindexand a Boolean value...
Step函数是一种在云计算中用于构建和管理工作流的服务。它允许开发人员以可视化的方式定义和组织多个任务或步骤,并在这些步骤之间进行条件判断和控制流程。 可重用状态定义是Step函数中的一个重要概念,...
Step Functions (以下简称SF)是AWS提供的一项无服务器编排服务,您可以将AWS Lambda 函数和其他 AWS 服务组合在一起,以构建关键型业务应用。通过 SF的图形控制台,您可以使用基于Json的ASL(Amazon Sate Language)快速构建可视化的应用程序工作流,并以图形界面方式监控每个工作流的运行状态。
今天,我们为您提供了通过 Step Function 状态机使用另外八项 AWS 服务的功能。以下是新操作: DynamoDB– 从Amazon DynamoDB表中获取现有项目;将一个新项目放入 DynamoDB 表中。 AWS Batch– 提交AWS Batch作业并等待其完成。 Amazon ECS– 使用任务定义运行Amazon ECS或AWS Fargate任...
