    Cloud VPS Instances - Free Traffic with Private Networks

    Please create a private network and use private IPs for free traffic between Cloud instances. Traffic between instances using private IPs within the same datacenter does not count toward your bandwidth allocation.

    How to Set Up Private Networks

    1. 1Log into the Cloud Control Panel
    2. 2Navigate to Networks section
    3. 3Create a new private network
    4. 4Attach your instances to the network
    5. 5Configure your services to use the private IPs

    Legacy SolusVM VPS

    Same Datacenter

    For legacy OpenVZ VPS instances on the same node or within the same datacenter, traffic between VPSs using their public IPs generally does NOT count toward bandwidth limits in most configurations. However, this is not guaranteed and can vary.

    Different Datacenters

    Traffic between VPSs in different datacenters (e.g., New York to Atlanta) DOES count toward your bandwidth allocation, as it traverses the public internet.

    Best Practices

    For Cloud Instances

    • Always use private networks for inter-instance communication
    • Keep instances that need to communicate in the same region
    • Use private IPs for database connections
    • Use private IPs for caching servers (Redis, Memcached)
    • Configure backups to use private network connections

    For Legacy VPS

    • Keep related services in the same datacenter
    • Use localhost or 127.0.0.1 when services are on the same VPS
    • Monitor bandwidth usage if transferring large amounts of data
    • Consider upgrading to Cloud VPS for private networking features

    Monitoring Bandwidth Usage

    You can monitor your bandwidth consumption through:

    • Cloud Control Panel - Real-time bandwidth graphs
    • SolusVM Control Panel - Current usage statistics
    • Client Area - Detailed bandwidth history

    Optimizing Bandwidth

    To reduce bandwidth usage between servers:

    • Compress data before transfer
    • Use rsync with compression (-z flag)
    • Implement caching to reduce repeated transfers
    • Schedule large transfers during off-peak hours
    • Use CDN for static content delivery

    Recommendation

    For the best performance and to ensure free inter-instance traffic, we strongly recommend using Cloud VPS with private networks. This gives you complete control over which traffic is metered and which is free.
