Concurrency is the number of in-flight requests that your AWS Lambda function is handling at the same time. For each concurrent request, Lambda provisions a separate instance of your execution environment. As y
Ensure the IAM user that performs this task in the console has admin permissions for the Lambda service -- i.e., Create, Update, Delete, Get and Invoke operations -- andiam:PassRole. This specifies the execution IAM role users assign to their Lambda function. Step 1. Create function To c...

securityGroupIds(list of SecurityGroup IDs):用于每个 Lambda 函数的 VPC 配置的安全组列表(可选)。请注意,您的 VPC 应配置为允许公共互联网访问(通过 NAT 网关)或包括 VPC 端点到 Lambda 服务。 subnetIds(list of Subnet IDs):用于每个 Lambda 函数的 VPC 配置的子网列表(可选)。请注意,...
这样的需求使用自带的budgets就很难满足了,所以我决定使用Lambda自行开发一个这样的函数 原理是: 首先使用EventBridge设置一个Cron定时触发器,来触发lambda函数 然后使用lambda函数调用CostExplorer的SDK获取我们想要的数据并展示出来 最终效果如图二, 二 在lambda导入外部依赖的时候,发现无法导入,查看了文档后发现可以将外部...
ability to filter messages before the invocationof a Lambda function. Filtering is supported for the following event sources:Amazon Kinesis Data Streams,Amazon DynamoDB Streams, andAmazon SQS. This helps reduce requests made to your Lambda functions, may simplify code, and can reduce overall cost....
The graph helps you understand the impact of the power configuration on cost and performance for your specific AWS Lambda function. For example, this is what the results look like for two CPU-intensive functions, which become cheaper AND faster with more power: ...
A sample authentication service implemented with a server-less architecture, using AWS Lambda to host and execute the code and Amazon DynamoDB as persistent storage. This provides a cost-efficient solution that is scalable and highly available and can be

首先Lambda本身是个无状态的逻辑单元,既不能直接接受API request,也不能持久化任何的状态。这一特性决定了Lambda往往会和API Gateway和类似DynamoDB、Kinesis这样的数据服务一起使用。在衡量是使用EC2,container还是Lambda的时候,这两部分的连带费用需要一起考虑。另外比较复杂的状态机系统可能还会用到step function作为...
