👉 The Fluid attribute in AWS describes the scalability and flexibility of an Amazon Resource Name (ARN) in response to changing workloads, particularly in the context of AWS Lambda and other serverless services. It measures how quickly an ARN can scale up or down to accommodate varying demand without manual intervention, ensuring efficient resource utilization. Fluid ARNs can handle sudden spikes in traffic or processing needs by rapidly increasing capacity, and conversely, they can scale down during periods of low demand to minimize costs. This attribute is crucial for maintaining optimal performance and cost-efficiency in serverless architectures, allowing developers to focus on writing code rather than managing infrastructure.
