One of the key players in serverless architecture is AWS with its AWS-Lambda offering: a simple way to execute a small portion of stateless code, on demand, without the need to provide any servers. AWS Lambda is often combined with AWS API gateway to provide the front end and execution layer of a REST API. Cassandra is one of the most popular solutions for back-end storage of large-scale applications. It’s always on, scalable and provides very low latency.
In this presentation, we walk through a POC that combines AWS Lambda, API Gateway and Instaclustr Apache Cassandra Managed Service, to power a simple REST API. We also cover the technical challenges, tips learned along the way and discuss the pros and cons of this approach.
