Resolution evaluate

The next diagram illustrates the answer structure.

The go with the flow of the answer is as follows:

1. The DNS question in your MSK endpoint is routed to a in the neighborhood configured on-premises DNS server.
2. The on-premises DNS as configured plays conditional forwarding for kafka-serverless.REPLACE-MSK-SERVERLESS-REGION.amazonaws.com to an Amazon Path 53 inbound resolver endpoint IP deal with.
3. The inbound resolver endpoint plays DNS solution by way of forwarding the question to the non-public hosted zone that was once created at the side of the MSK Serverless cluster.
4. The IP addresses returned by way of the DNS question are the non-public IP addresses of the interface VPC endpoint, which enable your on-premises host to determine non-public connectivity over AWS VPN or AWS Direct Attach.
5. The interface endpoint is a choice of a number of elastic community interfaces with a non-public IP deal with to your account that serves as an access level for site visitors destined to a MSK Serverless provider.

Notice that right now, this answer works just for MSK Serverless clusters with a unmarried VPC.

Necessities

On this phase, we speak about the prerequisite steps to finish with a purpose to put into effect this answer.

This guarantees that your on-premises community can be in contact with MSK Serverless at the specified port.

Configure a Path 53 inbound resolver endpoint

MSK Serverless supplies a DNS endpoint that serves as the start line for an Apache Kafka shopper to connect with the cluster. Alternatively, this endpoint isn’t publicly discoverable and will simplest be accessed from inside the configured VPC. To get to the bottom of the serverless DNS endpoint out of doors of your VPC, you’ll be able to arrange a Path 53 resolver endpoint. This lets you get admission to the endpoint securely by way of making a hybrid cloud setup over VPN or Direct Attach.

To configure the Path 53 resolver the use of the console, entire the next steps:

1. At the Path 53 console, underneath Resolver within the navigation pane, make a choice Inbound endpoints.
2. Select Create inbound endpoint.

3. For Endpoint title, input the endpoint title.
4. For VPC within the Area, make a choice the VPC the place you configured MSK Serverless.
5. For Safety crew for this endpoint, make a choice the safety crew that you just created as a prerequisite for inbound TCP/UDP connections.

The protection crew of the inbound resolver endpoint must permit site visitors from the on-premises DNS Server IP deal with on TCP/UDP port 53.

In your next step, you upload your IP addresses, making sure that the selection of IP addresses fits the selection of subnets to your MSK cluster.

6. Select the Availability Zones and subnets which might be the similar as your MSK Serverless community configuration.
7. Choose Use an IP deal with this is decided on mechanically.

8. Select Create inbound endpoint.

9. Replica the inbound endpoint IP addresses.

Configure the on-premises DNS server

On this instance, we use a Microsoft DNS server. To configure a conditional forwarder, entire the next steps:

1. Open DNS Supervisor.
2. Run the next command within the Run command window:

3. Select (right-click) Conditional Forwarders underneath the server of your opting for, then make a choice New Conditional Forwarder.

In your next step, you input kafka-serverless.REPLACE-MSK-SERVERLESS-REGION.amazonaws.com, the use of the IP deal with of Path 53 inbound resolver endpoints that you just created previous. You’ll be able to in finding the MSK endpoint knowledge by way of having access to the cluster’s shopper knowledge. To be informed extra about getting shopper knowledge, check with
In your next step, you input kafka-serverless.REPLACE-MSK-SERVERLESS-REGION.amazonaws.com, the use of the IP deal with of Path 53 inbound resolver endpoints that you just created previous. You’ll be able to in finding the MSK endpoint knowledge by way of having access to the cluster’s shopper knowledge.
