{: #interconnectivity}
Given that VPCs are regional constructs, the following questions quickly arise:
- How can I interconnect my VPCs with my on-premises network?
- How can I interconnect my VPCs?
{: #interconnectivity-onprem}
IBM has the following offerings that can interconnect a VPC with an on-premises network:
-
{{site.data.keyword.dl_full_notm}} Dedicated provides low-latency, high-throughput connections between {{site.data.keyword.cloud_notm}} VPC networks directly to a service provider-managed WAN, or a client-managed cloud backbone. Optimize egress traffic from your VPC network and reduce your egress costs. If you can’t connect at an {{site.data.keyword.cloud_notm}} data center, or don’t need more than 5 Gbps of bandwidth on a Virtual Network Connection, you can use {{site.data.keyword.dl_full_notm}} Connect to connect to {{site.data.keyword.cloud_notm}} through a supported service provider.
With {{site.data.keyword.dl_full_notm}} Global Routing capabilities, you get connectivity to all IBM Cloud regions worldwide from a single {{site.data.keyword.dl_full_notm}} connection. You can also take advantage of {{site.data.keyword.dl_full_notm}} service provider partners to establish more secure hybrid connections for your workloads across the globe. Easily provision multiple connections as more capacity is needed.
-
{{site.data.keyword.dl_full_notm}} Connect provides connectivity between your on-premises and {{site.data.keyword.cloud_notm}} VPC networks through a supported service provider. A service provider connection is useful if your data center is in a physical location that can't reach a dedicated colocation facility, or if your data needs don't warrant a 5 Gbps+ connection. Connect service providers are often used to facilitate multicloud connectivity (public clouds from multiple vendors) via their network. Connect service providers offer Layer-2 connectivity, Layer-3 connectivity, or both. Work with your service provider to understand their offerings and requirements.
-
VPN for VPC can securely connect your virtual private cloud to another private network. You can use VPN to set up an IPsec site-to-site tunnel between your VPC and your on-premises private network or another VPC. See Connecting to your on-premises network using a VPN gateway for details.
{: #interconnecting-vpcs}
{{site.data.keyword.tg_full_notm}} provisions and defines connections between resources on the {{site.data.keyword.cloud_notm}} network, providing private interconnectivity between {{site.data.keyword.cloud_notm}} data centers worldwide. {{site.data.keyword.tg_full_notm}} provides a central hub for connectivity, making it easier to provision and manage your networks. With {{site.data.keyword.tg_full_notm}}, you can create a single transit gateway or multiple transit gateways to connect {{site.data.keyword.cloud_notm}} VPCs. You can also connect your {{site.data.keyword.cloud_notm}} classic infrastructure to a transit gateway to provide seamless communication with classic infrastructure resources. Any new resource that you connect to a transit gateway is automatically made available to every other resource connected to it. All data remains within the private {{site.data.keyword.cloud_notm}} backbone and is optimized for performance.
{: #interconnectivity-benefits}
Benefits of these interconnectivity offerings include:
- Traffic between your on-premises network and your VPC network doesn't traverse the public internet. Traffic traverses a dedicated connection, or through a service provider with a dedicated connection.
- By bypassing the public internet, your traffic takes fewer hops, so there are fewer points of failure where your traffic might get dropped or disrupted.
- Move data to and from your on-premises data centers into the {{site.data.keyword.cloud_notm}} with uninterrupted, consistent network performance while protecting sensitive, business-critical data.
- Save on data transfer to and from servers in every {{site.data.keyword.cloud_notm}} data center across our private network, avoiding bandwidth fees.
