High speed low latency networks now allow us to add these nodes anywhere in a cloud infrastructure and configure them under existing load balancers. Once federated storage solutions other than the Prometheus time series database may be used to record metrics over longer periods of time. This enables the Kubernetes autoscaling.

If you’d like to play around with Cumulus Linux but don’t have a compatible hardware switch, Cumulus VX is the answer. This article listing 20 Linux server hardening tips contains some basic tips but is nevertheless a very good resource for someone looking for Linux security recommendations.

Russell Bryant has a couple great articles on OVN— how to test OVN’s “EZ Bake” release with DevStack as well as an article on implementing OpenStack security groups using OVN ACLs (which in turn leverage the integration between Open vSwitch and the Linux kernel’s conntrack module).

For example, if you are on a team selling AWS services or solutions, you should have a general understanding of what the cloud is, what AWS is specifically, and it’s limitations, without in-depth ability to use it. Key services on the AWS platform and their common use cases (for example, compute and analytics). Storage in AWS.

Examples of SDN/NFV workloads include wireless BTS, CRAN, MME, DSLAM, BRAS, and core routers. Workloads are scheduled across these server/linecards using Valiant Load Balancing (VLB). Of course, there are issues with packet-level load balancing and flow-level load balancing, so tradeoffs must be made one way or another.

The “gotcha” is that these software stacks haven’t been written yet, so the idea of repurposing hardware from switch to firewall to load balancer is still a bit of a unicorn. First, here’s a workaround to the fact that vCA doesn’t (yet) do cloud-init, which makes injecting SSH keys into Linux instances a bit difficult.

While the example I’m going to provide here is fairly simple, it should serve as a reasonable basis upon which to build later. OS X provides an SSH agent by default, but on Linux systems you will probably have to manually run an SSH agent and add the appropriate SSH key: eval `ssh-agent -s` ssh-add ~/.ssh/keyfile.pem.
