AWS Lamda

3 minute readExtensibilityDeveloper productivity

AWS Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume.

With Lambda, you can run code for virtually any type of application or backend service - all with zero administration. Just upload your code and Lambda takes care of everything required to run and scale your code with high availability. You can set up your code to automatically trigger from other AWS services or call it directly from any web or mobile app.

Plugin Version 1.3.3.2020102201 Revised on December 19, 2018

Setting up the plugin configuration

Plugin configurations are sets of parameters that apply across some or all of the plugin procedures. They reduce repetition of common values, create predefined sets of parameters for end users, and store credentials securely. Each configuration has a unique name that is automatically entered in designated parameters in the procedures.

  2. Find the EC-AWS-Lambda row.

  3. Click Configure to open the AWS Lambda Configurations page.
