You can use a FinSpace virtual private cloud (VPC) connection to allow the compute resources running in your FinSpace environment infrastructure account to access resources in your internal network. For example, a FinSpace analyst can connect their FinSpace managed Spark cluster to an internal code repository or internal application REST service. Using this feature, you can also connect to databases on your corporate network and access data, which you could then combine with data in FinSpace.
How a FinSpace VPC connection works
You create a FinSpace VPC connection by connecting your FinSpace infrastructure account to an existing transit gateway in your organization. You can configure the transit gateway to route traffic to other portions of your network. The following diagram shows how a FinSpace VPC connection works.
The diagram describes a high-level setup of a FinSpace VPC connection:
-
Each FinSpace environment contains a dedicated, service-managed AWS account called an environment infrastructure account.
-
In this account, there is a VPC. This VPC contains non-routable subnets that host FinSpace managed compute resources. The VPC also contains routable subnets that host a private NAT gateway. The private NAT gateway is connected to a customer managed transit gateway through a transit gateway attachment.
-
As shown in the diagram, you can connect the transit gateway that you manage to additional parts of your network, including your VPCs and on-premises networks. You can also configure a network path from this transit gateway to the internet if you want to.
-
The non-routable subnets that are in the VPC in the FinSpace infrastructure account use ranges within a Classless Inter-Domain Routing (CIDR) block of 192.168.0.0/16. The routable subnets use CIDR ranges that you provide. This diagram shows an example of using a 100.64.0.0/26 CIDR range, which you provide for use in two Availability Zones (AZs).
-
In the VPC of the environment infrastructure account, a Route 53 outbound resolver forwards custom DNS queries to a custom DNS server that you specify.
-
FinSpace creates multiple AZs in a Region and private NAT gateways in every AZ.
DNS resolution
The VPC in the environment infrastructure account contains a Route 53 resolver that is used by the hosts for DNS lookups. By default, after you configure a VPC connection, this resolver resolves AWS service names, but not other hosts on your network or the internet.
When you set up your FinSpace VPC connection, you can optionally configure this resolver so that it forwards queries to a resolver that you specify. This allows hosts that are running in the FinSpace infrastructure account to be able to resolve hostnames from this resolver.
