Managed Databases

Deploy, scale, and manage high-performance PostgreSQL, MySQL, Redis, and MongoDB instances with zero operational overhead. Includes automatic backups, point-in-time recovery, and read replicas.

Overview

CloudNexus Managed Databases provide fully managed relational and NoSQL databases deployed on isolated, high-performance infrastructure. Each instance includes automatic failover, continuous backups, and encryption at rest and in transit.

ℹ️ New in v3.2

Auto-scaling read replicas are now available for PostgreSQL and MySQL clusters. See the Scaling section for details.

Supported Engines & Versions

Engine	Supported Versions	Default Port	SSL/TLS
PostgreSQL	14, 15, 16	5432	Required
MySQL	8.0, 8.4	3306	Required
Redis	7.2, 7.4	6379	Supported
MongoDB	6.0, 7.0	27017	Required

Connection Strings & Environment Variables

Upon creation, CloudNexus automatically generates secure connection strings and injects them into your cloud environment variables if deployed on our platform.

env

# PostgreSQL
DATABASE_URL=postgres://user:password@primary.db.cloudnexus.io:5432/mydb?sslmode=require

# MySQL
MYSQL_URL=mysql://user:password@primary.db.cloudnexus.io:3306/mydb?tls=true

# Redis
REDIS_URL=rediss://user:password@cache.db.cloudnexus.io:6379

# MongoDB
MONGODB_URI=mongodb+srv://user:password@cluster.db.cloudnexus.io/mydb?ssl=true&replicaSet=rs0
                

⚠️ Security Notice

Never commit connection strings containing plaintext credentials to version control. Use our CLI or Terraform provider to manage secrets securely.

Scaling & Resource Management

CloudNexus databases automatically scale IOPS and network throughput based on workload patterns. You can manually adjust CPU and memory tiers via the dashboard, CLI, or API.

Read Replicas

Deploy read replicas in any of our 50+ global regions to reduce latency for geographically distributed applications. Replicas replicate synchronously to ensure zero data loss.

bash

$ cnx db replica create --name "mydb-eu-west" --region "eu-west-1" --source "mydb-primary"
✓ Replica provisioning complete in 14s
✓ Connection endpoint: replica-eu-west.db.cloudnexus.io
                

Vertical Scaling

Scale up CPU and memory with zero downtime. CloudNexus handles the live migration automatically during the next maintenance window or on-demand.

Backups & Point-in-Time Recovery

All managed databases include continuous automated backups. Retention policies default to 7 days for Standard tier and 30 days for Business/Enterprise.

bash

# Restore to specific point in time
$ cnx db restore --db "mydb" --to "2025-03-15T14:30:00Z" --target "mydb-restored"

# List available backups
$ cnx db backups list --db "mydb"
                

CLI & API Usage

Automate your database lifecycle using the CloudNexus CLI or REST API. The CLI uses OAuth2 authentication and supports Terraform state integration.

bash

# Initialize CLI
$ cnx auth login
✓ Authenticated as user@company.com

# Create database
$ cnx db create --engine postgres --version 16 --tier business --name "production-db"
✓ Database created. ID: db_8x9k2m4p
                

Troubleshooting

Common issues and solutions:

Connection refused / Timeout: Verify your project's firewall rules and IP allowlists. Databases are private by default.
Too many connections: Enable connection pooling or scale up the tier. Default limits are 500 (Standard) and 2000 (Business).
SSL handshake failed: Ensure your client trusts the CloudNexus CA certificate. Download it here.
