Redis In-Memory Database and Cache | Support by cloudimg

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

Deploy a fully configured, security-hardened Redis node that accepts connections within minutes of instance launch. Built for backend developers, platform engineers, and DevOps teams who need an unambiguously open-source Redis under the BSD licence - with no licensing compliance risk for SaaS products or commercial deployments.

Unlike Redis AMIs that ship with shared default credentials or require manual hardening steps after launch, this image enforces password authentication from the moment Redis starts. A unique, strong password is generated per instance on first boot - eliminating the credential-sharing risk that leads to unauthorized access. The final open-source release line under the BSD licence means no vendor lock-in and no licence ambiguity following Redis Ltd.'s move to dual SSPL/RSALv2 licensing.

• Redis server and redis-cli installed from the official Redis package repository
• Auto-starting service listening on port 6379, ready for client connections immediately after boot
• Static identification page on port 80 confirming the image is alive and directing administrators to the credentials file
• RDB snapshot persistence enabled by default; append-only file (AOF) persistence documented in the user guide

1. Launch your EC2 instance with this AMI
2. A one-shot systemd service generates a cryptographically strong password for the default Redis user
3. The password is applied to the running server via a configuration drop-in (not stored in the main redis.conf)
4. Credentials are written to a file readable only by root
5. Anonymous connections are refused - authentication is enforced immediately

No shared or default Redis credential ever ships in the image.

This Redis AMI runs on Amazon EC2 instances of any supported type. Pair it with:

• Amazon VPC for network isolation and security group rules controlling access to ports 6379, 80, and 22
• Amazon CloudWatch for instance-level monitoring of CPU, memory, and network metrics
• Amazon EBS for durable storage backing RDB snapshots and AOF files
• AWS Systems Manager for patch management and remote session access without opening SSH to the internet

Popular client frameworks including Node.js (ioredis), Python (redis-py), Java (Jedis/Lettuce), and Spring Boot connect without modification.

• Security groups: Allow inbound TCP on port 6379 (Redis clients), port 80 (status page), and port 22 (SSH administration)
• Instance sizing: Minimum t3.small for development; m5 or r5 family recommended for production workloads requiring larger memory allocations
• Storage: General Purpose SSD (gp3) EBS volume; size according to your dataset plus snapshot overhead

A development team running a web application behind an Auto Scaling group deploys this AMI as a centralized session store. Each application server connects to the Redis instance on port 6379 using the per-instance password. Sessions persist across application server scaling events, and the RDB snapshot ensures session data survives instance reboots. The BSD licence allows embedding in commercial SaaS products without licence review overhead.

• Application caches reducing database load
• Real-time leaderboards and counters
• Rate limiting and feature flags
• Pub/Sub messaging and lightweight streaming
• Job queues for background workers
