AWS Lambda is a serverless compute service that abstracts away the need to manage infrastructure, operating systems, logging, and other tasks, freeing up developers to focus on their application code. By utilizing AWS Lambda, developers can scale their applications without needing to worry about complex frameworks like Kubernetes. This makes it an ideal choice for time-series applications that process high volumes of data, as Lambda can seamlessly scale up or down depending on the incoming data volume. Additionally, when no data is being received, Lambda can even scale to zero, eliminating unnecessary server costs. The integration with Timescale Cloud allows developers to leverage a powerful open-source relational database designed specifically for time-series and analytics use cases.
