Serverless Battleground - DynamoDB vs Firestore vs MongoDB vs Cassandra vs Redis vs FaunaDB

We built a sample application which compares the performance of leading serverless databases using a common web use case and serverless functions. The databases are DynamoDB, MongoDB (Atlas), Firestore, Cassandra (Datastax Astra), FaunaDB and Redis (Upstash)

Stateful AWS Lambda with Redis REST

AWS Lambda pioneered serverless space. Many developers think that serverless is the future of development. It gives you the true pay-per-use model, relieves you from the maintenance and scaling of the backend infrastructure. But it also comes with challenges. One of those is its statelessness. You need to keep the state in an external data store. Unfortunately most of the popular data stores are connection based. But as we explained in this post, managing connections can become painful in serverless. That’s why, we have developed a high performance REST API on top of Upstash Redis. In this blog post, I will implement a very basic stateful api (page counter) on AWS Lambda and Upstash Redis using the REST API.
