I asked the question earlier how does NSX bring value to the enterprise. You can save money if you consolidate your Windows & Linux workloads to fewer servers. The Second are is the higher level layers such as load balancing. Cloud Computing Network Virtualization NSX SDN VMWare vmworld'

Vincent Bernat has a really in-depth article on IPv4 route lookup on Linux (and one on IPv6 route lookup as well). Cloud Computing/Cloud Management. A few interesting things jumped out at me from the report; one of them was regarding an increase in “siloism” as organizations embraced multiple clouds.

I think this three-part series on new network models for cloud computing ( part 1 , part 2 , and part 3 ), while almost a year old, is quite good. Cloud Computing/Cloud Management. Only a true geek would be interested in this, but here’s some information on running OpenBSD in KVM on Linux. That’s pretty handy.

The current GSA applications look like stovepipes that often implement replicated services using different technologies and solutions (different RDMS solutions, different load balancers, duplicate identity/access management solutions). This solution uses tools like Consul, Jenkins, Docker & Docker Swarm, HAProxy, Chef, and AWS.

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.

Another good resource is Dan Hersey’s guide to building an SDN-based private cloud in an hour. Cloud Computing/Cloud Management. If any enterprise Puppet experts want to give it a go, I’d be happy to publish a guest blog post for you with full details on how it’s done. Ben Armstrong shows how here.

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. Metadata can be assigned either via cloud-config parameters passed when the instance is spawned, or via modifications to the fleet config files.

Golub gives a “shout out” to the technologies underpinning modern Linux containers (namespaces, cgroups, etc., He then spends the next several minutes talking about various metrics—pull requests, containers pulled, Docker-ized apps, extent of usage among enterprises, etc.—all By “challenges,” they mean that the platform was crashing.
