Koha Cloud Enterprise on AWS

99.99% Availability Design

Multi-Availability Zone (Multi-AZ) deployment across multiple independent AWS data centers. Your library stays online even if an entire data center fails.

• Automatic failover in seconds
• Geographic redundancy across data centers
• Continuous health monitoring & auto-recovery
• Zero-downtime maintenance windows

Intelligent Auto-Scaling

System automatically adjusts compute capacity based on real-time demand, ensuring consistent performance during peak periods like course registration.

• Scales up during high traffic (auto-adds servers)
• Handles thousands of concurrent users
• Scales down during quiet periods (cost optimization)
• Application Load Balancer (ALB) distributes traffic

Amazon Aurora Database Performance

Amazon Aurora delivers up to 5× faster performance than standard MySQL databases for your catalog and circulation data.

• High-performance managed database
• Continuous automated backups
• Point-in-time recovery (1-35 days)
• MySQL-compatible

Dual-Layer Backup Protection

Two independent backup systems work together to protect your library data with flexible retention policies.

• Aurora continuous backups
• Scheduled Amazon S3 (Simple Storage Service) backups (hourly to weekly)
• Encrypted backup storage
• Customizable retention (30 days to years)

Enterprise Security

Bank-level security with encryption at rest and in transit, plus automatic security patching.

• Data encrypted in storage & transmission
• Automatic security updates
• Secure HTTPS connections
• Isolated network architecture

Shared File Storage (Amazon EFS)

Amazon Elastic File System (EFS) automatically synchronizes book covers, uploads, and reports across all servers in real-time.

• Real-time file synchronization
• Accessible from all servers
• Automatic scaling
• High durability storage

Zero-Downtime Upgrades

Update to new Koha versions without taking your library offline. Simply update the AMI ID in CloudFormation.

• Rolling deployment strategy
• New instances launch automatically
• Traffic shifts gradually to new version
• Not available in Standard tier

Application Load Balancer (ALB)

Automatically distributes traffic across multiple servers with automatic failover to healthy instances

Multi-AZ Auto Scaling

Automatically adds or removes servers based on traffic. Servers span multiple Availability Zones (data centers)

Amazon Aurora Database

Managed MySQL-compatible database with automatic backups, replication, and point-in-time recovery

Amazon EFS (Shared Storage)

Distributed file system shared across all servers for cover images, uploads, and reports

CloudWatch Monitoring

Real-time metrics, automated alarms, and system health dashboards
