What is Azure Managed Instance for Apache Cassandra? 

The simplest way to get an Apache Cassandra datacenter up and running in Azure and connected to your existing cluster. What is Azure Managed Instance for Apache Cassandra? Off-the-shelf Apache Cassandra with most of the control you have with self-hosting, but less of the maintenance chores. A gateway to cloud- native with Azure Cosmos DB Cassandra API.

Here’s what you have to do without Managed Instance…. 

Nodetool repairs, decommissions, bootstrap etc. Capacity Management Installing, Upgrading Cassandra Provisioned for the peak 

Managed Instance for Apache Cassandra will manage… Deployment We manage the entire process of VM provisioning, Cassandra and auxiliary services startup, and ring configuration. Scale For scale up, as with deployment, we provision the new machines and modify the ring. For scale down, we handle the removal process in safe way to avoid availability/data loss Maintenance OS patching, Cassandra patching, VM health, Cassandra service health, anti-virus, supply chain security, and the compliance coverage of the Azure cloud 

Migration/Hybrid Cassandra Cluster If you want Azure to act as an additional data center in your existing on-premises cluster… Azure Managed Instance enhances this capability, by reducing deployment and maintenance friction for new datacenters.
