Here’s a quick look at using Envoy as a load balancer in Kubernetes. Via Alex Mitelman’s Systems Design Weekly 015 , I was pointed to this AWS article on multi-site active-active architectures. It’s a good starting point for thinking about operating your own active-active architecture.

From the operator’s point of view, network virtualization allows each tenant (or customer) to see a single network switch that is specific to that tenant or customer. Some of these services naturally should run on the top-of-rack (ToR) switch, like load balancing or security services. So how does this work?

Normally the hardware space is pretty boring (in fact, I’ve been considering removing it from the Technology Short Take series), but HPE decided to shake things up recently with its Synergy servers and “composable architecture”. Operating Systems/Applications. Want to run Docker Swarm on Azure? Virtualization. Good write-up.

David Holder walks through removing unused load balancer IP allocations in NSX-T when used with PKS. Operating Systems/Applications. Systango has this high-level overview of serverless application architecture along with some pros/cons, use cases, etc. I’m looking forward to seeing how NaaS evolves.

I might have mentioned this before, but Ken Pepple’s OpenStack Folsom architecture post is just awesome. Operating Systems/Applications. I found this article on imperative vs. declarative system configuration is quite helpful in understanding Puppet’s declarative model. Cloud Computing/Cloud Management.

This is an awesome overview of the OpenStack Folsom architecture , courtesy of Ken Pepple. Operating Systems/Applications. In any case, this article by Frank Denneman on Storage DRS load balancing frequency might be useful to you. Cloud Computing/Cloud Management. Definitely worth reading, in my view.
