Isolated Instance Traffic, Included Free
RamNode private networking gives every instance in your project a dedicated, isolated network for secure internal communication. It is included at no extra cost with every Virtual Private Cloud.
What Is Private Networking?
Private networking creates a dedicated layer-2 network inside your RamNode Virtual Private Cloud. Each instance gets an internal IP address that is reachable only by other instances attached to the same private network, keeping internal traffic off the public internet.
The private network keeps your instances' internal traffic separate from the public internet, so you can build secure multi-tier architectures, replicate databases, run backend services, and orchestrate containers without exposing internal endpoints. All instances on the same private network can communicate directly and at full host speeds.
What Can You Use Private Networking For?
Any architecture that has internal traffic between instances can benefit from an isolated private network.
Database Replication
Replicate MySQL, PostgreSQL, MongoDB, or other databases between nodes over a secure internal link, avoiding public exposure of database ports.
Multi-Tier Applications
Separate web, application, and database tiers onto different instances while letting them communicate privately inside the same VPC.
Internal Services
Run caches, message queues, search indexes, and APIs on private IPs so they are reachable only by your application servers.
Reduced Attack Surface
Keep sensitive traffic off the public internet. Internal ports and management interfaces do not need public IP addresses or firewalls.
High-Speed Internal Traffic
Traffic between instances on the same private network stays on the host fabric, delivering low latency and full bandwidth without egress metering.
Cluster Communication
Connect Kubernetes nodes, Docker Swarm hosts, or distributed storage clusters over a reliable internal network with stable addressing.
Why Use RamNode Private Networking?
Included at no extra cost. Private networking is built into every RamNode Virtual Private Cloud. There are no per-network fees, no bandwidth charges for internal traffic, and no limit on the number of instances you can attach.
Private traffic isolation. Internal traffic stays on the private network, separated from the public internet and other customer traffic.
Works with security groups. Layer private network rules on top of your existing security groups for defense in depth.
API and CLI control. Create networks, attach subnets, and assign ports through the cloud control panel, OpenStack CLI, or infrastructure-as-code tools.
Complements public IPs. Instances can keep a public IP for inbound traffic while using private IPs for internal communication.
