## Apache Cassandra AMI by cloudimg - Production-Ready on AWS

Deploy Apache Cassandra on AWS with confidence using this pre-configured AMI backed by 24/7 cloudimg support. This AMI eliminates hours of manual setup by delivering an EC2-optimized Cassandra installation with JVM tuning, monitoring agents, enhanced networking drivers, and security hardening - so your team can focus on building applications rather than configuring infrastructure.

## What This AMI Delivers Beyond Stock Cassandra

This is not a bare Cassandra install. Every AMI includes:

• JVM tuning optimized for EC2 - Garbage collection and heap settings configured for AWS instance memory profiles
• CloudWatch Agent pre-installed - Monitor Cassandra metrics directly in your AWS console without additional setup
• Systems Manager Agent - Manage instances at scale using AWS Systems Manager
• ENA drivers for enhanced networking - Take full advantage of AWS network performance
• NVMe drivers for optimal I/O - Configured for high-throughput storage on NVMe-backed instances
• Data and commit log directories configured - Proper separation for production workloads
• Optimized garbage collection - Reduced GC pauses for consistent latency
• Security hardening applied - Reduced attack surface for production deployment
• Multiple Cassandra versions available spanning multiple OS variants

## Solve Real Problems at Scale

IoT Time-Series Ingestion: Cassandra excels at high-velocity write workloads. Ingest millions of sensor readings per second across a multi-node cluster, with TTL-based auto-expiration managing data retention automatically. The masterless architecture means no single point of failure as your IoT fleet scales, and multi-datacenter replication keeps data available even during regional outages.

## Core Cassandra Capabilities

• Masterless distributed architecture - all nodes are equal, no single point of failure
• Linear scalability - add nodes without downtime, double nodes for double throughput
• Multi-datacenter replication with tunable consistency (strong to eventual)
• CQL query language familiar to SQL users (SELECT, INSERT, UPDATE, DELETE)
• Zero Copy Streaming for faster node rebuilds
• Wide row and column family data model
• Secondary indexes, materialized views, and lightweight transactions
• TTL for automatic data expiration
• Multiple compaction strategies for storage optimization

## High Availability and Resilience

• No single point of failure in the cluster
• Multi-datacenter replication for disaster recovery
• Automatic failover with hinted handoff
• Zero downtime during maintenance and scaling
• Self-healing gossip protocol
• Read repair and anti-entropy mechanisms
• Withstands full datacenter outages
• Incremental backups and point-in-time recovery

## Clustering on AWS

• Horizontal scaling with virtual nodes for balanced data distribution
• Rack and datacenter awareness maps to AWS Availability Zones
• Gossip protocol for automatic node discovery
• Dynamic cluster expansion without downtime
• Compatible with EC2 instances, EBS volumes, and instance storage
• Recommended instances: r5/r6i (memory-intensive), i3/i4i (high I/O), m5/m6i (balanced), minimum r5.large

## Getting Started

1. Launch the AMI on your chosen EC2 instance type (minimum r5.large recommended)

2. Configure seed nodes in cassandra.yaml for multi-node clusters

3. Start the Cassandra service

4. Nodes auto-discover each other via the gossip protocol

5. Connect using CQL and begin creating your keyspaces

For multi-region deployments, configure the snitch and replication strategy to span AWS regions for disaster recovery and low-latency global access.

## Use Cases

• Time-series data for IoT and sensor networks
• Real-time analytics and streaming pipelines
• User activity tracking and personalization
• Product catalogs and inventory management
• Social media feeds and messaging platforms
• Financial transactions and fraud detection
• Media streaming and content delivery
• Gaming leaderboards and player state
• Recommendation engines
• Multi-region distributed applications

## 24/7 Support Included

Every subscription includes 24/7 cloudimg support with a guaranteed 24-hour response SLA and average one-hour response for critical issues. Support covers architecture guidance, cluster design and optimization, CQL query tuning, data modeling, replication strategy recommendations, performance troubleshooting, backup and recovery, and multi-datacenter deployment planning.
