Lambda<\/a>\u00a0is an Amazon Web Services (AWS) masterpiece which helps in leveraging compute services for a duration of seconds to minutes and hence reduces the infrastructure costs manifolds and its maintenance.<\/p>\n

The Cron expressions are created, evaluated and triggered using Cloudwatch Management Console. The possible cron expressions for AWS Lambda are discussed in this<\/a> link. In this blog, you can see that Lambda is triggered, based on Cron expressions.<\/p>\n

There are two ways to create Cron expressions triggers, demonstrated below.<\/p>\n

First<\/strong>, go to Cloudwatch Management Console\u00a0> Rules > Schedule. Specify the desired Cron expressions and Add target to a pre-created Lambda Function.<\/p>\n

\"CloudWatch<\/p>\n

Second<\/strong>, visit Lambda Management Console > Create a Lambda function > Select Blueprint (Choose the Blueprint you want) > Configure triggers (Choose CloudWatch Events – Schedule) as following:<\/p>\n

\"Lambda<\/p>\n

Enter the Rule Name, Description, Schedule expression and then enable the trigger:<\/p>\n

\"Enable-trigger\"<\/p>\n

In the next stage, enter the desired Lambda Function which you need to perform. The cron expression can be validated in CloudWatch Console > Rules.<\/p>\n

\"cron-cw\"<\/p>\n

It will serve as a centralized place for keeping and monitoring of all the cron expressions used in the infrastructure.<\/p>\n
