To www or not to www – Should you use www or not in your domain?
Cookies set from a hostname, will also be sent to all subdomains ... There is a limitation in DNS which says that the origin, must be an A type record, which means it has to point to a fixed IP address ... But there are important matters that says you should use the full hostname with the www: Perfomance-wise, security-wise and in terms of flexibility.

Meet Slingshot: An Innovative Interconnect for the Next Generation of Supercomputers | Cray Blog
Slingshot has a crop of new features aimed at data-centric HPC and AI workloads. It starts with extremely high bandwidth: 12.8 Tb/s/dir per switch, from 64 200 Gbps ports. All those ports allow us to build very large networks with very low diameter. Slingshot implements the dragonfly topology, which Cray invented back in 2008. We can create networks with over a quarter million endpoints, with a diameter of just three network hops. And only one of those hops needs to use an (expensive) optical cable. This reduces latency, but also reduces cost; the Shasta network requires half—or for larger systems, one quarter—the number of optical cables as a fat-tree to provide the same level of global bandwidth.

Kubernetes NodePort vs LoadBalancer vs Ingress? When should I use what?
Recently, someone asked me what the difference between NodePorts, LoadBalancers, and Ingress were. They are all different ways to get external traffic into your cluster, and they all do it in…
