Oracle Cloud Infrastructure FastConnect provides an easy way to create a dedicated, private connection between your data center and Oracle Cloud Infrastructure. FastConnect provides higher-bandwidth options, and a more reliable and consistent networking experience compared to internet-based connections.
Uses for FastConnect
With FastConnect, you can choose to use private peering, public peering, or both.
- Private peering: To extend your existing infrastructure into a virtual cloud network (VCN) in Oracle Cloud Infrastructure (for example, to implement a hybrid cloud, or a lift and shift scenario). Communication across the connection is with IPv4 private addresses (typically RFC 1918).
- Public peering: To access public services in Oracle Cloud Infrastructure without using the internet. For example, Object Storage, the Oracle Cloud Infrastructure Console and APIs, or public load balancers in your VCN. Communication across the connection is with IPv4 public IP addresses. Without FastConnect, the traffic destined for public IP addresses would be routed over the internet. With FastConnect, that traffic goes over your private physical connection. For a list of the services available with public peering, see FastConnect Supported Cloud Services. For a list of the public IP address ranges (routes) that Oracle advertises, see FastConnect Public Peering Advertised Routes.
In general it's assumed you'll use private peering, and you might also use public peering. Most of this documentation is relevant to both, with specific details called out for private versus public.
If you choose to have multiple paths from your on-premises network to Oracle, see Routing Details for Connections to Your On-Premises Network.
IPv6 addressing is currently supported only in the US Government Cloud. For more information, see IPv6 Addresses.
How and Where to Connect
With FastConnect, there are different connectivity models to choose from.
Colocation with Oracle in an Oracle Cloud Infrastructure FastConnect Location
The following table summarizes several important requirements for each connectivity model.
Here are some important concepts to understand (also see the following diagrams):
- The general concept of a connection between your existing network and Oracle Cloud Infrastructure over a private physical network instead of the internet.
- FastConnect location
- A specific Oracle data center where you can connect to Oracle Cloud Infrastructure.
- metro area
- A geographical area (for example, Ashburn) with multiple FastConnect locations. All locations in a metro area connect to the same set of availability domains for resiliency in case of failure in a single location.
- Oracle provider
- A network service provider that has integrated with Oracle in a FastConnect location. See the list of the Oracle providers in How and Where to Connect. If your provider is in the list, see FastConnect: With an Oracle Provider.
- third-party provider
- A network service provider that is NOT on the list of Oracle providers in How and Where to Connect. If you have a third-party provider and want to use FastConnect, see FastConnect: With a Third-Party Provider.
- The situation where your equipment is deployed into a FastConnect location. If your network service provider is not on the list of Oracle providers in How and Where to Connect, you must colocate.
- In a colocation or third-party provider scenario, this is the physical cable connecting your existing network to Oracle in the FastConnect location.
- cross-connect group
- In a colocation or third-party provider scenario, this is a link aggregation group (LAG) that contains at least one cross-connect. You can add additional cross-connects to a cross-connect group as your bandwidth needs increase. This is applicable only for colocation.
- virtual cloud network (vcn)
- Your virtual network in Oracle Cloud Infrastructure. You can use a VCN to extend your infrastructure into the cloud. For more information, see VCNs and Subnets.
- dynamic routing gateway (drg)
- A virtual edge router attached to your VCN. Necessary for private peering. The DRG is a single point of entry for private traffic coming in to your VCN, whether it's over FastConnect or an IPSec VPN. After creating the DRG, you must attach it to your VCN and add a route for the DRG in the VCN's route table to enable traffic flow. Instructions for everything are included in the sections that follow.
- virtual circuit
- An isolated network path that runs over one or more physical network connections to provide a single, logical connection between the edge of your existing network and Oracle Cloud Infrastructure. Private virtual circuits support private peering, and public virtual circuits support public peering (see Uses for FastConnect). Each virtual circuit is made up of information shared between you and Oracle, as well as a provider (if you're connecting through an Oracle provider). You could have multiple private virtual circuits, for example, to isolate traffic from different parts of your organization (one virtual circuit for 10.0.1.0/24; another for 172.16.0.0/16), or to provide redundancy.
Basic Network Diagrams
The diagrams in this section introduce the basic logical and physical connections involved in FastConnect. Details specific to private versus public peering are called out.
General Concept of FastConnect
The following diagram illustrates the two ways to connect to Oracle with FastConnect: either through colocation with Oracle in the FastConnect location, or through an Oracle provider. In both cases, the connection goes between the edge of your existing network and Oracle.
The next two diagrams give more detail about the physical connections. They also show the metro area that contains the FastConnect location, and a VCN within an Oracle Cloud Infrastructure region.
The first diagram shows the colocation scenario, with your physical connection to Oracle within the FastConnect location.
The next diagram shows a scenario with either an Oracle provider or third-party provider. It shows your physical connection to the provider, and the provider's physical connection to Oracle within the FastConnect location.
Logical Connection: Private Virtual Circuit
The next two diagrams show a private virtual circuit, which is a single, logical connection between your edge and Oracle Cloud Infrastructure by way of your DRG. Traffic is destined for private IP addresses in your VCN.
The first diagram shows the colocation scenario.
The next diagram shows the scenario with either an Oracle provider or third-party provider.
Logical Connection: Public Virtual Circuit
A public virtual circuit gives your existing network access to Oracle services in Oracle Cloud Infrastructure. For example, Object Storage, the Oracle Cloud Infrastructure Console and APIs, and public load balancers in your VCN. All communication across a public virtual circuit uses public IP addresses. For a list of services available with FastConnect public peering, see FastConnect Supported Cloud Services. For a list of the public IP address ranges (routes) that Oracle advertises, see FastConnect Public Peering Advertised Routes.
The first diagram shows the colocation scenario with both a private virtual circuit and a public virtual circuit. Notice that the DRG is not involved with the public virtual circuit, only the private virtual circuit.
The next diagram shows the scenario with either an Oracle provider or third-party provider.
Here are a few basics to know about public virtual circuits:
- You choose which of your organization's public IP prefixes you want to use with the virtual circuit. All prefix sizes are allowed. Oracle verifies your organization's ownership of each prefix before sending any traffic for it across the connection. Oracle's verification for a given prefix can take up to three business days. You can get the status of the verification of each prefix in the Oracle Console or API. Oracle begins advertising the Oracle Cloud Infrastructure public IP addresses across the connection only after successfully verifying at least one of your public prefixes.
- You must configure your firewall rules to allow the desired traffic coming from the Oracle public IP addresses.
Your existing network can receive advertisements for Oracle's public IP addresses through multiple paths (for example: FastConnect and your internet service provider). Make sure to give higher preference to FastConnect over your ISP. You must configure your edge appropriately so that traffic uses your desired path and you receive the benefits of FastConnect. This is particularly important if you decide to also set up your existing network with private access to Oracle services. For important information about path preferences, see Routing Details for Connections to Your On-Premises Network.
- You can add or remove public IP prefixes at any time by editing the virtual circuit. If you add a new prefix, Oracle first verifies your company's ownership before advertising it across the connection. If you remove a prefix, Oracle stops advertising the prefix within a few minutes of your editing the virtual circuit.
Oracle Provider Scenario: BGP Session to Either Oracle or the Oracle Provider
This section is applicable if you're using FastConnect through an Oracle provider. A Border Gateway Protocol (BGP) session is established from your edge, but where it goes to depends on which Oracle provider you use.
For simplicity, the following diagrams show only a private virtual circuit. However, the location of the BGP session is the same for a public virtual circuit.
To Oracle: With some of the Oracle providers, the BGP session goes from your edge to Oracle, as shown in the following diagram. When setting up the virtual circuit with Oracle, you are asked to provide basic BGP peering information (see General Requirements).
To the Oracle provider: With other Oracle providers, your BGP session goes from your edge to the provider's, as shown in the following diagram. When setting up the virtual circuit with Oracle, you are NOT asked for any BGP session information. Instead, you share BGP information with your Oracle provider. Notice that there's a separate BGP session that the provider establishes with Oracle.
FastConnect with Access to Multiple VCNs
You can use a single FastConnect to access multiple VCNs. There are different network scenarios available depending on your needs and which FastConnect connectivity model you use. For more information, see these topics:
