Azure Managed Instance for Apache Cassandra: Apache Cassandra Datacenters
In the present competitive business environment, consistent and enhanced analysis and management of large volumes of data are one of the crucial functions to be executed by an organization. Over the past decades, certain types of data management architectures have evolved that have some unique potentials of their own. The Apache Cassandra architecture is an example of this development in the market. Designed to provide high scalability and extreme reliability in terms of storing huge volumes of data, the service provides a distributed system of data storage. In simple words, the distributed system can be deployed in a single machine or even in a docker container.
A single instance of the Apache Cassandra is termed as a ‘node’. Each of these nodes can perform all the database operations of the user organization even without requiring a master node. To enhance the productivity of the features provided by the Apache Cassandra architecture, Microsoft designed the Azure Managed Instance for Apache Cassandra which is currently in public preview.

An explanation of the features:
The features under the Azure Managed Instance for Apache Cassandra pricing range are currently available in the public preview format. This implies that not all the features are completely available in the present form. The basic aim behind developing this service was to provide the user companies, the ability to manage the native clusters of the Apache Cassandra in the cloud platform through the use of certain analytics tools that can initiate automated deployment to the cloud from the on-premises infrastructure.
In addition to this, the service also helps the user to scale operations in mixed reality or hybrid scenarios and also consistently reduces the management cost. In the present competitive business environment, while moving to the cloud platform is a quite challenging experience, it is also equally inevitable. This implies the need for adapting to the changing norms that are associated with running a platform as a service solution. At times the user companies may also need to use certain features of Apache Cassandra that are not suited in the Cassandra API of Azure Cosmos DB as well as the cloud-native environment.
But, with the use of Azure Managed Instance for Apache Cassandra, the user organization can easily provision hosted data and back up the center of the Apache Cassandra, to the Azure cloud along with complete features compatibility.
Certain additional capabilities can also be considered as additional features that are also included within the service. These include the following:-
- Hybrid data services which include connectivity with a certain existing on-premises or a cloud cluster.
- The existing Apache Cassandra deployments can be moved to the Managed Instance with zero downtime.
- The Apache Cassandra nodes can be scaled up and down in the Azure Data centre.
- The previous data centre can be safely deleted.
- A repair action can be started on a keyspace.
- The configurations of the backup centre can be changed.
- The service performs automated periodic backups.
- The advanced security features of the service provide the organizational data they required security at the app level.
- The service also performs seamless replication to Azure Cosmos DB Cassandra API.
Database Management through Azure Managed Instance for Apache Cassandra:
The Database Management feature of the Azure Managed Instance for Apache Cassandra is one of the important benefits of the service. In a situation where the user organization considers using Cassandra as a bridge to Azure Cosmos DB, the Azure clusters have to be configured as a hybrid cluster. But, even before creating a Cassandra cluster, the user company needs to deploy it, name it and later connect it to the Azure Virtual Network.
To manage the data in a hassle-free manner, the Cassandra has to be configured for performing node-to-node encryption. This feature has to be enabled even if the service is not using Cassandra for the on-premise installation. Later, the encryption certificate has to be installed in an Azure-hosted cluster using the Azure CLI which allows the two sites to communicate through an encrypted gossip connection. In addition to this, the Azure CLI has to be used to send the details of the node and for creating a new data center in the azure managed cluster.
In addition to simplifying data management within the service, the Azure Managed Instance for Apache Cassandra also has the potential to support certain other Azure applications including the Azure Databricks, Azure Apache Spark Analytics, and other analytics tools. The service is designed by Microsoft which has been consistently depicting its commitment to cloud operations in a hybrid environment through the manipulation of data.
The Managed route to running Cassandra in the Azure Cloud helps in creating a bridge of NoSQL data between the on-premise tools and the cloud platform. Finally, the proprietary replication protocol of Cassandra ensures the data replication and the Azure cloud ensures that the data is up to date and secure.
Benefits of the instance-based pricing:
There appears to be not much difference between running Apache in the Azure cloud or other open-source databases. Within the Azure cloud, the user company needs to login to the Azure Portal, search for a Managed Instance for Apache Cassandra, and subsequently create clusters. But, to add an Azure Service to the subscription, the user needs to follow certain steps including the filling up of the resource group option and choosing a location. In addition to this, a name and VM type also have to be selected.
The current preview format is limited to DS14_v2 servers that are attached to 4 P30 disks. The user company should expect to pay atheists $2.11 per hour per server, which is dependent on where the service is provisioned. But, the instance-based pricing model is beneficial for the fact that the user pays for only the storage capacity used, and even the first two backup copies of the data are provided free of cost. This refers to successful cost management by the user company while using the Azure Managed Instance for Apache Cassandra.
Storage limitations of Azure Managed Instance for Apache Cassandra:
The storage and throughput limits of the service are dependent on the Virtual Machine SKUs chosen by the user organization.
