In this webinar, we cover a few different options for Cassandra as a service in the cloud. We introduce DataStax Astra, Amazon Keyspaces, and Microsoft Azure Cosmos DB. We also have a live demo where we take a deeper look at each of them to see how easy it is to spin up a database on each of the platforms, while also checking out some cool features that each service provides directly on the platform such as CQL terminals, notebooks, and monitoring.

3. Cassandra as a Service in the Cloud
● DataStax Astra
● Amazon Keyspaces
● Microsoft Azure Cosmos DB
● Other Notables
○ Instaclustr
■ Instaclustr provides a fully managed and SOC 2 certified hosted & managed service for Apache Cassandra® on AWS, Azure, GCP,
and IBM Cloud.
○ Aiven
■ Aiven for Apache Cassandra is a managed and hosted distributed NoSQL database providing scalability, high availability, and
excellent fault tolerance. Cassandra as a Service is available on Google Cloud Platform, Amazon Web Services, Microsoft Azure,

4. DataStax Astra
● https://github.com/Anant/cassandra.api
● 10 Gig Free Tier
● Eliminate the overhead to install, operate, and scale
Cassandra
● Out-of-the-box REST and GraphQL endpoints and
browser CQL shell
● Powered by DataStax’s open-source Kubernetes
Operator for Cassandra
● Deploy on AWS or GCP and keep compatibility with
open-source Cassandra
● Put your data where you need it without compromising
performance, availability or accessibility
● Move your apps to Astra with the Cassandra Migration
Tool.

5. Amazon Keyspaces
● Scalable, highly available, and managed Apache Cassandra–compatible database service
● Enables you to use the Cassandra Query Language (CQL) API code, Cassandra drivers,
and developer tools that you already use. Updating applications to use Amazon Keyspaces
is as easy as changing the Cassandra hostname to the Amazon Keyspaces service
endpoint.
● Serverless, so you pay for only the resources you use and the service can automatically
scale tables up and down in response to application traffic
● Consistent, single-digit-millisecond response times at any scale. Build applications with
virtually unlimited throughput and storage that can serve thousands of requests per
second without the need for capacity planning.
● Offers a 99.99% availability SLA within an AWS Region. Tables are encrypted by default
and replicated three times in multiple AWS Availability Zones for high availability.
● Create continuous table backups with hundreds of terabytes of data with no performance
impact to your application, and recover to any point in time in the preceding 35 days.

6. Microsoft Azure Cosmos DB
● Fully managed NoSQL database service
● Fast, flexible app development with SDKs for popular languages,
APIs for SQL, MongoDB, Cassandra, and Gremlin, and no-ETL
(extract, transform, load) analytics
● Fully managed and cost-effective serverless database with
instant, automatic scaling that responds to application needs
● Ready for mission-critical applications with guaranteed business
continuity, 99.999-percent availability, and enterprise-level
security
● Guaranteed speed at any scale even through bursts-with instant,
limitless elasticity, fast reads and multi-master writes, anywhere
in the world
