In our initial discussion, we explored fundamental design patterns for achieving substantial scalability in serverless applications. In this follow-up, we delve into the various methods for invoking Lambda functions and highlight essential considerations for each invocation model.
Synchronous Invocations
Synchronous invocations represent the most straightforward approach to triggering your Lambda functions. This method allows for immediate response and is typically used when the calling service requires a quick answer. However, it’s important to note that this type of invocation can lead to throttling if requests exceed the function’s concurrency limits.
Asynchronous Invocations
Asynchronous invocations, on the other hand, enable functions to be triggered without waiting for a response. This model is beneficial for processes that do not require immediate feedback, allowing for greater flexibility and efficiency. For instance, if you’re interested in exploring a role in e-commerce management, check out this job listing for an Ecommerce Fulfillment Manager at Rifle Paper Co.
Event Source Mappings
Event source mappings facilitate automatic invocation of Lambda functions in response to specific events. They are especially useful in scenarios where you want to trigger actions based on changes in data, such as updates in databases or file uploads to storage services.
Direct Invocations
Direct invocations can be performed through API Gateway or other AWS services, allowing for seamless integration of Lambda with different applications. This method is particularly effective for building serverless RESTful APIs.
It’s essential to understand the implications and use cases for each invocation method to optimize your serverless architecture. For authoritative guidance on job descriptions related to financial roles, you can visit SHRM’s resource on job descriptions for Treasurer and Controller.
