Why customers choose Oracle Cloud Networking and Connectivity
Lowest network pricing
We offer low networking prices that let customers move significant volumes of data—such as live video streaming, video conferencing, and gaming—at very low costs, saving customers up to 80% versus other clouds. Inbound data transfer is free, and we offer 10 TB of outbound data transfer at no cost, whereas AWS only offers 1 GB and Azure just 5 GB.
Oracle Cloud economicsRDMA cluster networking for HPC
Oracle’s cluster networking provides access to RDMA over converged Ethernet (RoCE) v2 and a 100 Gbps network to create HPC clusters with microsecond latencies—ideal for the highest throughput, lowest latency, and most demanding HPC workloads.

On-premises–level control in the cloud
Oracle virtual cloud networks (VCNs) provide a customizable and private network in Oracle Cloud Infrastructure. Just like a traditional data center network, the VCN provides you with complete control over your network environment. This includes assigning your own private IP address space, creating subnets and route tables, and configuring stateful firewalls.
Key features
- Fully configurable IP addresses
- 10 VCNs per region
- Up to 300 subnets per region
- 300 route tables per VCN
- Up to 100 rules per route table
- Bring your own IP Address (BYOIP)
Run HPC workloads with minimal latency
Oracle’s cluster networking provides RDMA (remote direct memory access) over converged Ethernet (RoCE) v2 and a 100 Gbps network to create HPC clusters with microsecond latencies—ideal for the most demanding HPC workloads.
HPC use cases
- Computational fluid dynamics
- Molecular modeling
- Automobile collision emulation
- 3D video rendering and animation
- Weather forecast modeling
- Financial risk simulations
- Contextual search
- Deep learning, AI, and machine learning
Private, dedicated connection into Oracle Cloud
Oracle FastConnect allows customers to connect directly to their Oracle Cloud Infrastructure virtual cloud network via dedicated, private, high-bandwidth connections. Move data over the dedicated line at a low, flat monthly rate based on the port speed chosen, not the amount of data transferred.
Key features
- Predictable connectivity via deterministic paths
- More than 50 FastConnect partners
- Colocation cross-connects available
- No charge for inbound or outbound data
Connect securely with Oracle Cloud VPN
Site-to-Site VPN allows you to establish an encrypted IPSec connection (with two IPsec tunnels) from your on-premises data center to Oracle Cloud Infrastructure, keeping your data secure while using your existing internet connections.
Key features
- Static routing
- BGP dynamic routing
- Preshared keys
- IKEv1 and IKEv2
- Diffie-Hellman groups 1, 2, 5, 14, 19, 20
- AES 256
- SHA-2 256 and SHA-2 384
- HMAC-SHA-196 and HMAC-SHA-256-128
Increasing application availability
Oracle Cloud Infrastructure (OCI) Flexible Load Balancing enables customers to distribute requests across a fleet of servers or automatically route traffic across availability domains, yielding highly available and fault-tolerant applications. The portfolio consists of two services—Oracle Cloud Infrastructure Flexible Load Balancer (OCI Load Balancer) and Oracle Cloud Infrastructure Flexible Network Load Balancer (OCI Network Load Balancer).
Key Flexible Load Balancer features
- Layer 4 (TCP) and layer 7 (HTTP) proxy load balancer
- Guaranteed and flexible bandwidth (bursting)
- SSL offload/termination
- Cookie-based session persistence
- Supports TLS 1.2
Key Flexible Network Load Balancer features
- Layer 3 and Layer 4 (TCP/UDP/ICMP) pass-through load balancer
- Low latency
- Optimized for long-lived connections
- Source and destination IP preservation
Ensure optimal website and web application performance
Public DNS provides high availability and global traffic shaping for your applications no matter where they run, ensuring optimal website and web application performance.
Key features
- Active failover
- Ratio load balancing
- Geolocation steering
- ASN and IP prefix steering
- Secondary DNS redundancy
Service Gateway
Oracle Cloud Service Gateway provides a customer’s on-premises network with private access to Oracle Cloud services. Once connected to your VCN, Service Gateway allows secure, private connectivity to Oracle Cloud services like compute instances, cloud storage, containers, and databases.
Key features
- Private access to Oracle Cloud
- Network traffic avoids public internet
- End-to-end network security
- Connect with VPN or FastConnect
- Easy to configure
- Works with 50+ Oracle Cloud Infrastructure (OCI) services
- Adapts to network changes
- Gateway support for NAT, DRG, LPG

How to Launch a Virtual Cloud Network Using the Networking Quickstart Wizard and Connect to Your Autonomous Database
Can Tuzla, Senior Product ManagerA virtual cloud network (VCN) is a virtual, private network you set up in Oracle data centers. It is very similar to a traditional network with firewall rules and various gateways. When you work with Oracle Cloud Infrastructure (OCI), setting up a VCN for your cloud resources is usually one of the first things that you might be doing.
