What Is Direct Cloud Connect?
Direct Cloud Connect generally refers to a private network connection between an organization's infrastructure and a cloud provider. It allows systems to exchange traffic through a private or dedicated network path instead of relying primarily on the public internet.
In simple terms, Direct Cloud Connect provides a controlled network path between dedicated infrastructure and cloud services for workloads that require predictable connectivity, latency, or bandwidth.
The exact implementation depends on the cloud provider and network architecture. Major providers use their own product names, such as AWS Direct Connect and Google Cloud Interconnect, while network providers may offer managed private cloud connectivity services.
At XLC, Direct Cloud Connect provides private connectivity from XLC infrastructure to AWS, Microsoft Azure, Google Cloud, Alibaba Cloud, and Oracle Cloud.
How Does Direct Cloud Connect Work?
A private cloud connection establishes a network path between the customer’s infrastructure and the cloud provider.
A typical deployment involves:
- Choose the cloud provider and region – Select the cloud environment and location that need to be connected.
- Define connectivity requirements – Determine bandwidth, traffic patterns, latency requirements, and redundancy needs.
- Provision the connection – Establish the physical or logical interconnection between the networks.
- Configure the cloud-side interface – Set up the required virtual interface, VLAN attachment, routing, and access configuration.
- Exchange traffic privately – Applications and systems communicate through the private connection rather than relying on normal public-internet routing.
The exact process varies between providers. For example, AWS Direct Connect supports dedicated and hosted connections, while Google Cloud offers Dedicated and Partner Interconnect options.
For XLC’s service, engineers provision a dedicated physical cross-connect from the server rack directly to the cloud provider’s network fabric within the facility, then provide the connection details needed to configure the cloud-side interface.
Direct Cloud Connect vs Public Internet
Both approaches can connect infrastructure to cloud services, but they use different network paths.
| Characteristic | Direct Cloud Connect | Public Internet |
|---|---|---|
| Network path | Private or dedicated interconnection | Shared public network |
| Routing control | Greater control over the connection | Depends on internet routing |
| Latency consistency | Generally more predictable | Can vary with routing and congestion |
| Network exposure | Traffic can avoid public network paths | Traffic traverses public networks |
| Capacity | Provisioned according to the connection | Depends on available internet connectivity |
| Best suited for | Steady, high-volume, or latency-sensitive traffic | General-purpose connectivity |
A private connection does not automatically make an application secure. Access controls, encryption, network segmentation, and correct configuration are still required.
Direct Cloud Connect vs VPN
A VPN can also connect infrastructure to a cloud environment, but it typically establishes an encrypted tunnel over the public internet.
Direct Cloud Connect uses a private or dedicated network path instead of relying on the public internet as the underlying transport.
| Characteristic | Direct Cloud Connect | VPN |
|---|---|---|
| Underlying path | Private or dedicated interconnection | Usually public internet |
| Encryption | Depends on architecture | Typically encrypted |
| Routing variability | Generally lower | Can inherit internet variability |
| Bandwidth | Depends on provisioned connection | Depends on internet and VPN infrastructure |
| Typical use | High-volume or latency-sensitive traffic | Secure site-to-site or remote connectivity |
VPNs can be an effective solution for many use cases. Private interconnects become more relevant when organizations need higher throughput, predictable network behavior, or a controlled connection between infrastructure and cloud environments. Google Cloud, for example, positions Cloud Interconnect for higher-throughput connectivity and Cloud VPN for lower-bandwidth or migration scenarios.
What Are the Benefits of Direct Cloud Connect?
More Predictable Network Performance
A private connection can reduce dependence on unpredictable public-internet routing and congestion. This can make network behavior more consistent for applications that continuously exchange data with cloud services.
Private Network Path
Traffic can remain off the public internet between the connected infrastructure and cloud environment. This reduces exposure to public network paths, although additional security controls may still be required.
High-Bandwidth Connectivity
Private interconnections can provide substantial provisioned capacity for workloads that transfer large amounts of data between infrastructure and cloud platforms. The available capacity depends on the provider and connection type.
Hybrid Cloud Support
Direct Cloud Connect allows organizations to combine dedicated physical infrastructure with cloud services rather than moving every workload into the same environment.
Potentially Lower Transfer Costs
Depending on the cloud provider, region, traffic direction, and connection model, private connectivity may help reduce or better control cloud data-transfer costs. Pricing should always be evaluated against the provider’s current rates.
XLC specifically positions its Direct Cloud Connect service around latency consistency, predictable throughput, and potential cloud data-transfer savings.
How Is Routing Managed?
Private cloud connections commonly use routing protocols such as BGP to exchange reachability information between connected networks.
BGP allows the networks to advertise routes and determine how traffic should be exchanged between the infrastructure and cloud environment.
For example, Google Cloud uses Cloud Router and BGP with Cloud Interconnect to exchange routes between a VPC network and a connected external network.
For more information about the routing protocol itself, see the BGP glossary entry.
What Is Direct Cloud Connect Used For?
Direct Cloud Connect is most useful when an organization needs regular, high-volume, or latency-sensitive communication between dedicated infrastructure and cloud services.
Hybrid Cloud Infrastructure
Organizations can keep compute-intensive or always-on workloads on dedicated physical servers while using cloud-native services for databases, analytics, storage, application services, or other functions.
XLC specifically supports this model by connecting its dedicated infrastructure to major cloud platforms through private connectivity.
Large-Scale Data Transfer
Organizations moving large datasets between physical infrastructure and cloud storage or processing environments can use private connectivity instead of relying entirely on public-internet paths.
AI and Machine Learning
AI workloads may combine dedicated GPU or compute infrastructure with cloud services for storage, orchestration, analytics, or other parts of the workflow.
Database and Application Connectivity
Applications running on dedicated infrastructure may need to communicate continuously with databases, APIs, or other services hosted in the cloud. A private connection provides a more controlled path for this traffic.
Multi-Cloud Architectures
Organizations using several cloud platforms can use private connectivity to integrate dedicated infrastructure with different cloud environments as part of a broader hybrid or multi-cloud architecture.
Direct Cloud Connect vs Cloud Network
A cloud network is a broader networking environment used to connect cloud resources, infrastructure, users, and other networks.
Direct Cloud Connect is a specific connectivity mechanism within that broader architecture.
For example, an organization may use a cloud network to manage connectivity between its infrastructure and cloud environments, while Direct Cloud Connect provides a private connection to a particular cloud platform or region.
Direct Cloud Connect vs Peering
Peering is a network arrangement in which two networks exchange traffic directly, usually through an internet exchange or another interconnection point.
Direct Cloud Connect is more specifically focused on private connectivity between customer infrastructure and a cloud provider.
The two can complement each other. Peering can improve routing between networks, while Direct Cloud Connect provides a dedicated path for specific infrastructure-to-cloud traffic.
What Should You Consider When Choosing Direct Cloud Connect?
The right private connectivity solution depends on the workload and network architecture.
Consider:
- Cloud provider – Confirm that the required cloud platform and region are supported.
- Location – Check whether the infrastructure and cloud interconnection point are available in suitable facilities.
- Bandwidth – Estimate both steady-state and peak traffic requirements.
- Latency – Consider physical distance and the network path between infrastructure and cloud resources.
- Traffic direction – Analyze inbound and outbound traffic because cloud data-transfer pricing can differ by direction.
- Routing – Determine how routes will be exchanged and managed between environments.
- Redundancy – Consider multiple connections or paths for critical workloads.
- Security – Review segmentation, access controls, encryption requirements, and monitoring.
- Pricing – Compare connection, cross-connect, cloud-provider, and data-transfer costs.
For XLC infrastructure, the broader network infrastructure includes private cloud interconnects alongside BGP routing, Tier 1 transit, and other connectivity capabilities.
XLC’s commercial Direct Cloud Connect service currently supports private connectivity from XLC dedicated servers to AWS, Microsoft Azure, Google Cloud, Alibaba Cloud, and Oracle Cloud.
