Amazon Keyspaces is a scalable, highly available, and managed Apache Cassandra–compatible database service. This service offered by Amazon is serverless, so the user does not have to worry about maintaining the server, it also has the advantage of auto-scaling so it can deal with heavy workloads and you only pay for what you use.
In the traditional model a user is in charge of monitoring and troubleshooting the cluster of Cassandra’s of nodes, the management of the cluster could also be problematic, especially if it is in production, if the problems could not be solved in an acceptable time frame.
Using Amazon Keyspaces offers high availability by storing copies of the data in three Availability Zones, so if for any reason the service fails in one, the information would be available for use, it also solves the problem of having to buy new equipment for scalability by using auto-scaling.
Amazon Keyspaces also encrypts data at rest and with other services like AWS Identity and Access Management (IAM), and virtual private cloud (VPC) endpoints, the user gets a layer of security of its data and connections.
