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.

And when we find that, we’ll want to see interface errors, DNS response times, TCP retransmissions from container resources, and so on, all in a time series to identify what is causing that latency. Just seeing more data points won’t help maintain a reliable network, but understanding how those data points relate to each other will.

TCP/IP is one of the fundamental networking protocols and the basis for common protocols like HTTP. IP address abstraction and failover capabilities with DNS Domain Name System (DNS) is a system for mapping domain names to IP addresses. This is another facet of network resilience.

For more complex networking, this might be an IP address associated with a given network interface on a machine. which means listening on all interfaces. For these comms, we need to use the internal IP of the EC2 machine (or hostname, if DNS is configured). docker run -t --network kafka-listeners_default.

Figure 1: Different network protocols for OS identification based on the OSI model Starting from the bottom of the stack, at the data link layer, exists the medium access control (MAC) protocol. Over this protocol, a unique physical identifier, called the MAC address, is allocated to the network interface card (NIC) of each network device.

I'm learning kernel-bypass networking techniques using DPDK, and I have an AWS Amazon Linux 2023 VM with installed DPDK on it, running the DPDK skeleton basic forwarding sample application. I have my primary AWS ENA network interface for ssh access, and a secondary AWS ENA interface hooked to DPDK using the igb_uio kernel module.
