Do you love event-driven programming? Let's take a look at triggering AWS Lambda functions from AWS SNS messages.
In situations where a Lambda function’s executions are higher than the number of Provisioned Concurrency, this metric will show the number of executions above Provisioned Concurrency. Ideally, it should be zero, therefore it’s recommended to trigger an alarm when this value is > 0. Enable ...

AWS Lambda Retry policy Synchronous events(such as API Gateway): will not trigger any auto-retry policy. It’s the application’s responsibility to implement the fallback system. Async Events(such as SQS and SNS): will trigger two retries (by default). If all retries have failed, it’s ...
Well, we do know for sure that Lambda powers your code on some form of container technology which explains how AWS is able to get it to spin up so quickly as compared to running your code on standard EC2 instances. These containers are spun up on underlying EC2 instances that are all ...
Amazon SNS can be integrated with a wide range of AWS services, including Lambda, CloudWatch, and more. In this section, we’ll look at some of the key ways to integrate Amazon SNS with AWS services. Integration with AWS Lambda AWS Lambda is a serverless computing service that enables devel...
All CloudWatch alarms have the option to trigger an SNS notification. But once CloudWatch sends a notification to SNS, you have a number of options, such as calling an HTTP/HTTPS endpoint (useful for 3rd party tools such as PagerDuty or VictorOps), invoking a Lambda function, sending a mess...
