Classic database: Connect via a VPC

By creating a virtual private cloud (VPC), you can connect your VPC resources and DataStax Astra DB databases. VPC peering allows you to communicate across the VPCs.

VPC peering is available on only Classic C- and D-tier Astra DB databases.

VPC peering is available for all cloud providers available on Astra DB.

AWS VPC peering

By creating a virtual private cloud (VPC), you can connect your AWS resources and DataStax Astra DB databases. VPC peering allows you to communicate across the VPCs.

For more about VPC peering on Astra DB databases hosted on AWS, see What is VPC peering?.

VPC peering is available on only Classic C- and D-tier Astra DB databases.

Prerequisites

Create a VPC in your AWS account. See Create the VPC.
Create your Astra DB database. See Creating your Astra DB database.

Adding the peering connection

From your database Overview, select Add Peering Connection.
In Add Peering Connection, enter your Account ID from My Account within your AWS Console without any dashes.
Enter the VPC ID you want to use from your list of VPCs in your AWS VPC dashboard.
Enter the VPC CIDR (classless inter-domain routing) block for your AWS VPC. If desired, whitelist the CIDR block by selecting the option.

The CIDR block cannot overlap your Astra DB VPC CIDR block.
Select the receiving Application VPC Region.

To reduce latency, DataStax recommends selecting a geographically close region for the Astra DB database and your AWS VPC.
Select Initiate.

Accepting the peering request

Accept the peering connection:

aws ec2 accept-vpc-peering-connection --vpc-peering-connection-id ASTRA_CONNECTION_ID --region AWS_REGION

See Accepting a VPC peering connection.

Get the REQUESTER_VPC_CIDR_BLOCK:

aws ec2 describe-vpc-peering-connections --vpc-peering-connection-ids "$PEERING_CONNECTION_ID" --region "$REGION" | jq -r ".VpcPeeringConnections[].RequesterVpcInfo.CidrBlock"

Add the route in route table with sender’s CIDR and peering connection ID:

aws ec2 create-route --route-table-id AWS_ROUTE_TABLE_ID --destination-cidr-block REQUESTER_VPC_CIDR_BLOCK --vpc-peering-connection-id CONNECTION_ID --region AWS_VPC_REGION

See Updating your Route tables for a VPC peering connection. . Once you’ve created a VPC peering connection, download the secure connect bundle for internal VPC network to connect to your database.

Google Cloud VPC peering

By creating a virtual private cloud (VPC), you can connect your Google Cloud resources and DataStax Astra DB databases. VPC peering allows you to communicate across the VPCs.

For more about VPC peering on Astra DB databases hosted on Google Cloud, see VPC Network Peering overview.

VPC peering is available on only Classic C- and D-tier Astra DB databases.

Prerequisites

Create a VPC in your Google Cloud account.
Create your Astra DB database.

See Creating your Astra DB database.

Procedure

The procedure is a two-step process using Astra Portal and the Google Cloud Console.

Astra DB

From your database Overview, select Add Peering Connection.
In Add Peering Connection, enter the Google Cloud project name in the Project ID.
Enter the VPC Network Name from the list of VPCs in the VPC dashboard of your Google Cloud account. For example, default.
Select Initiate.

Google Cloud Console

Open your Google Cloud project.
In the left sidebar, navigate to VPC Network.
Open VPC network peering.

On the Create peering connection dialog, enter:
- A name for the connection you’re creating
- Your VPN network You may select default from the list.
- Under Peered VPC Network, enable In another project and enter:
- Astra DB Project ID: Found on your database page in Network Peering. For example, esmrahul3x7as3xbcj2grtexarskq.
- VPC network name: Found on your database page in Network Peering. For example, dse-4240ebe6-72e1-4ea1-ac25-cc728d9fa9ff.
