In Cloudera deployments on public cloud, one of the key configuration elements is the DNS. Get it wrong and your deployment may become wholly unusable with users unable to access and use the Cloudera data services. If the DNS is set up less ideal than it could be, connectivity and performance issues may arise.

How it used to be When I started my career in networking, servers were down the hall or in the campus data center. Most resources were local, accessed remotely over some sort of leased line, or at worst, over a site-to-site back to the organization’s private data center. Yes, of course, I’m oversimplifying here.

What is my performance to specific endpoints, between data centers or from on-prem to cloud? Configuration data. Questions you can answer with configuration data alone: Did I make an obvious mistake with a configuration change? In addition, DNS telemetry can be helpful to put traffic and other telemetry types in context.

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. And this, of course, is just to reach the front end.

Network reliability engineers (NREs) The scale, transient nature of resources and topology, and extensive network boundaries make delivering on network reliability a complex and specialized task. Additionally, monitoring becomes critical for network optimizations by identifying areas where resources are under or overutilized.

Employees constantly complain about performance While traditional hub-and-spoke networking topology comes with its advantages, when users backhaul to the data center they clog the network with bandwidth-heavy applications like VOIP and file transfer.
