Oracle Virtual Cloud Network

Oracle virtual cloud networks (VCNs) provide customizable and private cloud networks in Oracle Cloud Infrastructure (OCI). Just like a traditional data center network, the VCN provides customers with complete control over their cloud networking environment. This includes assigning private IP address spaces, creating subnets and route tables, and configuring stateful firewalls.

Virtual Cloud Network features

Customizable virtual networks

Flexible IP assignments

Customers define VCNs according to specific workload IP address requirements, and can divide a VCN into smaller ranges using private or public subnets or assign multiple IP addresses to a single VCN.

Extend existing networks

Extend existing on-premises networks and interconnects using virtual routers and gateways. Customers use peering gateways to connect different VCNs within a tenancy, or to connect securely to other tenancies.

Site-to-site connectivity

Expand your on-premises network to your Oracle Cloud VCN with a redundant VPN gateway (VPN Connect).

“Bring your own” public IP addresses

Bring whitelisted IP addresses or IP addresses that rely on reputation to Oracle VCNs to avoid disruptions or having to change IP addresses while migrating to Oracle Cloud.

Flat cost, high-speed connectivity

FastConnect allows customers to connect directly to their OCI virtual cloud network via dedicated, private, high-bandwidth connections. Then, based on the amount of data, customers simply chose an appropriate port speed and pay a consistent, low price each month. Other providers charge for the amount of data moved, which can be expensive and unpredictable.

End-to-end network security

Isolated network virtualization

Prevent attacks on customer tenancies with isolated network virtualization. A foundational element of OCI’s security-first architecture, the design stops malware with a custom-designed SmartNIC to isolate and virtualize the network.

Maximum security zones

With Oracle Maximum Security Zones, Oracle becomes the first public cloud provider to activate security policy enforcement of best practices automatically from day one, so customers can prevent misconfiguration errors and deploy workloads securely.

Oracle Cloud Guard

For day-to-day operations, Oracle Cloud Guard continuously monitors configurations and activities to identify threats and automatically acts to remediate them across all Oracle Cloud global regions. Oracle is the only cloud service provider to offer a cloud security posture management dashboard at no additional cost, with numerous pre-built tools that automate response to reduce customer risk quickly and efficiently.

Service gateways

Customers extend their VCN with private access to a complete range of OCI and platform services over service gateways, without traversing the public internet.

Low-latency networking yields high performance

High bandwidth, low-latency environment

Oracle’s cluster networking provides remote direct memory access (RDMA) over converged Ethernet (RoCE) v2 and a 100 Gbps network to create high performance computing clusters with microsecond latencies—ideal for the most demanding workloads.

Flat network

Oracle’s highly scalable, flat network design limits the number of network hops between compute and storage to a maximum of two. Oracle does not oversubscribe network resources, so customers experience a low-latency network, with predictable performance.

Performance SLA

Oracle is the only large cloud service provider to offer a performance SLA for networking. We guarantee consistent network performance for customers so they can rely on predictable network responses to their application workloads.

Protecting critical workloads

Disaster protection and hybrid connectivity

Customers implement offsite disaster recovery (DR) plans by extending workloads from an on-premises data center to Oracle Cloud, using a VPN or a dedicated FastConnect connection. Alternatively, customers can deploy VCNs in multiple regions using peering gateways to provide geographic workload redundancy.

Oracle web application firewall

Protect applications from malicious and unwanted internet traffic with a cloud-based, PCI-compliant, global web application firewall (WAF) service. By combining threat intelligence with consistent rule enforcement, the service strengthens defenses and protects internet-facing application servers.

Multi-cloud interoperability

Customers utilize a fast, secure, reliable connection directly between Oracle Cloud Infrastructure and Microsoft Azure. Available in US East (Ashburn) to Azure US East, Canada Southeast (Toronto) to Azure Canada Central, UK South (London) to Azure UK South, Netherlands Northwest (Amsterdam) and Azure West Europe, and Japan East (Tokyo).

Multiple-Region Peering and Latency Testing on Oracle Cloud Infrastructure in Europe

Alexander Koenig, Principal Product Manager, Oracle

This blog addresses multiple regional architectures. Many customers raised questions on latency expectations in Europe and the ability to deploy a database in one region while running the application in another. In this blog post, we use Oracle Autonomous Data Warehouse in Frankfurt and a business intelligence application in Amsterdam.
