Many people consider Apache Cassandra® and DynamoDB as potential datastore technologies when looking to build high-scale, high-reliability services in the cloud. Both technologies are popular and well-proven to deliver at scale. However, choosing the technology most appropriate for your use case can have a significant impact on the cost of building, maintaining, and running your application.
This whitepaper considers a real-world use case, analyzes the costs of running on Instaclustr Managed Apache Cassandra vs DynamoDB, and discusses how the features and cost models of the two technologies could impact the architecture of your solution. The use case we are considering is at the heart of Instaclustr’s monitoring system, Instametrics.
