What is AWS Lambda?
AWS Lambda lets you run code without provisioning or managing servers. You can upload your code and set it to automatically trigger from other AWS services, or call it directly from any web or mobile app. You can build serverless backends using AWS Lambda to handle web, mobile, Internet of Things (IoT), and 3rd party API requests.
How does AWS Lambda work?
You can use AWS Lambda to execute code in response to triggers such as changes in data, shifts in system state, or actions by users.
Orbita has a Lambda node that can call the AWS Lambda function, which acts as a connector between Orbita systems and the client’s systems.
Consider a use case where you create a flow in Orbita’s Experience designer that sends emails to the users, but the client does not want to expose its user information through APIs. In this case, the client can consider writing a code in AWS Lambda that interacts with client systems and fetches the requested details to Orbita.
