DNS Engineering Topology 
Cloudera Blog
FEBRUARY 12, 2024
In Cloudera deployments on public cloud, one of the key configuration elements is the DNS. If the DNS is set up less ideal than it could be, connectivity and performance issues may arise. In this blog, we’ll take you through our tried and tested best practices for setting up your DNS for use with Cloudera on Azure.

Why do we need to create site-to-site VPNs or some sort of modern SD-WAN topology connecting all our branches when almost all traffic goes to the public internet and the cloud? So what does this mean for today’s enterprise network engineer? This also means that today’s enterprise WAN poses new challenges for a network engineer.

We decided to seek potential solutions that could provide a more complete and unified picture of our networking topology. For example, our DNS probe has an event with just the network namespace id (netns), process id (pid), and the raw packet data. Our compute team has used DNS data to better understand large spikes in DNS traffic.

More than anything, reliability becomes the principal challenge for network engineers working in and with the cloud. Even the most detailed reliability engineering can be easily undermined in an insecure network. While there is much to be said about cloud costs and performance , I want to focus this article primarily on reliability.

The cost increase prompted our engineering team to investigate alternative ways to provide the same level of service more efficiently. Custom multi-cluster service discovery: Our custom service discovery solution, DoorDash data center Service Discovery, or DDSD, provides a custom DNS domain to support multi-cluster communication.

Cyberthreat strategies have evolved in step with modern cloud networks, often using cheap, virtualized cloud resources to exploit the threat surface topology I briefly described above. The attacker can spoof IP addresses, DNS, HTTPS headers, and more to deceive users into interacting with compromised applications.

An engineer standing in front of a console today stares at the traffic moving from their on-prem data center up and out to a CASB, receiving DNS responses from a cloud-provided DNS service, and then on through an ephemeral microservices architecture in a public cloud. Today, it’s up and out.
