Azure Managed Instance for Apache Cassandra

Azure Managed Instance for Apache Cassandra is a fully managed, highly available, and scalable Apache Cassandra solution that can be deployed into an Azure Virtual Network. It provides the flexibility of open-source Cassandra while eliminating the operational burden of managing infrastructure.

Note: This service is designed for users who need to run Apache Cassandra on Azure without the complexities of self-hosting. It offers enterprise-grade features and integration with other Azure services.

Key Features

Fully Managed: Microsoft handles patching, backups, monitoring, and availability.
High Availability: Built-in replication and fault tolerance ensure your data is always accessible.
Scalability: Easily scale your Cassandra clusters up or down based on demand.
Azure Integration: Seamlessly integrate with Azure Active Directory, Azure Monitor, and other Azure services.
VNet Native: Deploy directly into your Azure Virtual Network for secure and isolated access.
Cost-Effective: Pay only for the resources you consume, with predictable pricing.

Use Cases

Azure Managed Instance for Apache Cassandra is ideal for a wide range of workloads, including:

Internet of Things (IoT) data ingestion
Real-time analytics
Time-series data storage
Large-scale personalization and recommendation engines
Gaming leaderboards

Architecture Overview

The service abstracts away the underlying infrastructure. Each Cassandra cluster consists of multiple nodes organized into rings, providing high availability and fault tolerance. Data is distributed across these nodes using a consistent hashing algorithm.

Tip: Understand the Cassandra data modeling best practices to optimize performance and scalability for your specific use case.

Pricing

Pricing is based on the number of vCores, memory, and storage per node, as well as the duration of operation. You can estimate your costs using the Azure Pricing Calculator.

Example: Connecting with a Driver

Here's a simplified example of how you might connect to your Managed Instance using the DataStax C# Driver:

                
using Cassandra;
using System;
using System.Collections.Generic;

// ...

var options = new Cassandra.Policies.LoadBalancingPolicyOptions(
    default(string),
    default(string),
    default(int),
    default(int),
    default(int),
    default(int),
    default(int),
    default(int),
    default(int),
    default(int),
    default(int),
    default(string),
    default(string),
    default(string),
    default(string)
);
var lbPolicy = new Cassandra.LoadBalancing.DCAwareRoundRobinPolicy(region); // Replace 'region' with your data center name
var clientOptions = new Cassandra.Cluster.Builder()
    .AddContactPoint("your_managed_instance_ip_address") // Replace with your instance's contact point
    .WithPort(9042) // Default Cassandra port
    .WithAuthProvider(new Cassandra.PlainTextAuthProvider("your_username", "your_password")) // Use appropriate authentication
    .WithLoadBalancingPolicy(lbPolicy)
    .Build();

try
{
    using (var session = clientOptions.Connect())
    {
        Console.WriteLine("Connected successfully!");
        // Execute your Cassandra queries here
    }
}
catch (Exception ex)
{
    Console.WriteLine($"Connection failed: {ex.Message}");
}
