Networking Options for Dedicated Region Deployments

In Dedicated Regions, we deploy the Mission Control Agent and event broker services in a region controlled by Solace. If you require private Messaging Connectivity between the event broker services in your Dedicated Region and the virtual private cloud (VPC) where your client applications reside, we offer several networking options supported by your chosen cloud provider.

When deciding on the networking options for your Messaging Connectivity, consider the requirements of your entire estate, including:

• whether you need bidirectional or unidirectional network connectivity

• the amount of event broker services you want, or may require in the future

• bandwidth limitations

• support for multiple regions

• support for transitive routing

The tables below show the networking options supported by each of the cloud providers available for Dedicated Regions. They also provide information about the benefits and limitations of each option and links to any related documentation. Each table provides information about a specific cloud provider:

• Virtual Private Cloud (VPC) and Virtual Network (VNet) Peering

• Managed Hub-and-Spoke Networking

• Unidirectional Endpoints

• Site-to-Site Virtual Private Network (VPN)

You can see an overview of each networking option, including architectural diagrams, in Overview of Supported Networking Options for Dedicated Regions.

See Supported Networking Options for Dedicated Regions by Cloud Providers Supported by Solace for tables showing the Messaging Connectivity options supported by Solace for each cloud provider.

Overview of Supported Networking Options for Dedicated Regions

The sections below provide an overview and diagram of each of the networking options supported by Solace for Messaging Connectivity for Dedicated Regions.

• Virtual Private Cloud (VPC) and Virtual Network (VNet) Peering

• Managed Hub-and-Spoke Networking

• Unidirectional Endpoints

• Site-to-Site Virtual Private Network (VPN)

Virtual Private Cloud (VPC) and Virtual Network (VNet) Peering

With virtual private cloud (VPC) or virtual network (VNet) peering, Solace connects your Dedicated Region region with another Dedicated Region in the same cloud provider, or with your network. Multiple Dedicated Region regions and networks can be connected together this way.

The diagram below provides examples of VPC/VNet peering between two Dedicated Regions and VPC/VNet peering between a Dedicated Region and a customer network.

 

VPC/VNet peering is available for every cloud provider Solace deploys Dedicated Regions to:

• Azure VNET Peering

• Amazon VPC peering

• Google VPC peering

Benefits

• VPC/VNet peering is the simplest network solution for Messaging Connectivity.

Security Considerations

• Traffic can flow in both directions between the peered Dedicated Region and your network if your routing rules allow it. This can be useful if you want to enable certain features, like REST Delivery Points for your event broker services, which require both outbound and inbound connections.

Drawbacks

• The CIDR ranges of your Dedicated Regions and networks must be unique. They cannot overlap or match.

• Transitive peering is only available for Dedicated Regions deployed to Azure Kubernetes Service (AKS). 

Managed Hub-and-Spoke Networking

With managed hub-and-spoke networking, Solace connects your Dedicated Region region to your network transit hub, which connects to other Dedicated Regions, or your virtual private clouds and networks.

The diagram below provides an example of managed hub-and-spoke networking between a Dedicated Region and customer networks through a customer-owned hub.

 

The following managed hub-and-spoke networking options are supported by Solace:

• Azure Virtual WAN

• AWS Transit Gateway

Benefits

• Connectivity between the networks hosting your event broker services are simplified. You only have to worry about a single connection for each datacenter.

Security Considerations

• Traffic can flow in both directions between the peered Dedicated Region and your network if your routing rules allow it. This can be useful if you want to enable certain features, like REST Delivery Points for your event broker services, which require both outbound and inbound connections.

Drawbacks

• Solace recommends using unique CIDR ranges for your Dedicated Region and your networks when using managed hub-and-spoke for Messaging Connectivity.

Unidirectional Endpoints

With unidirectional endpoints, Solace connects the Dedicated Region region to your network by exposing an event broker service endpoint in your network. Traffic flows through the private endpoint, to and from the event broker service.

The following diagram provides an example of unidirectional endpoints, with private endpoints connecting customer networks to the event broker service in your Dedicated Region.

 

The following unidirectional endpoints options are available for connecting your Dedicated Region to your networks:

• Azure Private Link

• GKE Private Service Connect

Benefits

• It doesn't matter if the CIDR range of your network and your Dedicated Region match, or overlap.

• Network peering between the Dedicated Region and your network is not possible.

Drawbacks

• Communication is unidirectional. This means that features like RDP and Kafka Bridge won't work unless the destinations are accessible via the public internet.

• Setup is done with event broker service creation instead of when the Dedicated Region is created, which complicates manual configuration.

• Source IPs cannot be preserved, so broker ACLs can’t filter on source and debugging client connections can be complicated

 

Site-to-Site Virtual Private Network (VPN)

With site-to-site virtual private networking (VPN), Solace connects the Dedicated Region with another Dedicated Region, or with your network. Multiple Dedicated Regions and networks can be connected together this way.

Using site-to-site VPN for the Messaging Connectivity for your Dedicated Region is an additional add-on purchase. Contact Solace for information.

This diagram below provides examples of site-to-site VPN network between two Dedicated Regions deployed to different cloud providers, and site-to-site VPN between a Dedicated Region and a customer network.

 

Site-to-site VPN is available for every cloud provider Solace deploys Dedicated Regions to:

• Azure site-to-site VPN

• Amazon site-to-site VPN

• Google site-to-site VPN

Benefits

• Site-to-site VPN is the only option if your VPC or network is partially or completely on-premises, or if you want to connect multiple Dedicated Regions in different cloud providers (multi-cloud).

Drawbacks

• Site-to-site VPN is an add-on purchase, and is not included by default for Dedicated Region deployments.
