Calculating Your Cloud ROI
Like the cloud itself, determining your return on investment requires a different way of looking at goals and factoring in the value of opportunity and competitive advantage.Brocade Q3 Buoyed by Routers and Service Providers

Layer-3-Only Data Center Networks with Cumulus Linux on Software Gone Wild
With the advent of layer-3 leaf-and-spine data center fabrics, it became (almost) possible to build pure layer-3-only data center networks… if only the networking vendors would do the very last step and make every server-to-ToR interface a layer-3 interface. Cumulus decided to do just that.

Docker for NetOps
I have been spending this week in Silicon Valley at Network Field Day 10. One of the announcements struck a chord with me, as this year has marked some significant career changes for me: specifically an uptake in involvement with containers and software development. My good friend Brent Salisbury once wrote about the idea of using Golang for Network Operations tooling. While I’ve continued (and will continue) to build my Python skillset, I’ve also been getting more and more experience with Golang and with some of the great software projects created by it, such as Docker, and Kubernetes.Docker for NetOps

Brent has also more recently written about using Docker to build network tools, and I’d like to use this post to say I agree with this sentiment. Network Operations can really do more with container technology to accelerate what has traditionally been a pretty stagnant silo.
Fundamentally, the concept of application of containers is not that new, and admittedly, network engineers have not been required to think of them. I mean network operations is only now getting accustomed to delivering network services in form factors like virtual machines. It’s important to remember that solutions like Docker have provided application developers with Continue reading
Big Switch Improves Day to Day Network Operations
Big Switch recently launched major updates to their products Big Cloud Fabric (BCF) and Big Monitoring Fabric (BMF), formerly Big Tap. This post isn’t going to cover the updates or the products from an architectural standpoint, but rather two specific features that are meant to help general day to day network operations.
Command & API History
The first feature is simple – it shows command history, but also API history across the entire Big Cloud Fabric (BCF). The feature is accessed through the central UI of the BCF controller and you can simply look at the last N commands or APIs that were executed on the system. The great thing is that you don’t need a separate AAA system to capture the commands being made and should you want to see the API calls being generated from the CLI commands (because remember the CLI is just an API client), you can also view them. If the CLI isn’t being used, you can also still see each API call that has been recently made on the fabric. It’s my understanding that there is a certain amount of storage dedicated to this function so when the space does fill up, the history Continue reading

I mean network operations is only now getting accustomed to delivering network services in form factors like virtual machines. It’s important to remember that solutions like Docker have provided application developers with an consistent format for packaging what they produce. In network operations, we can take advantage of this same tooling - instead of asking our network vendors to make sure Python is installed on our switches, we need them only to support Docker.

A lesson in BitTorrent
Hackers have now posted a second dump of Ashley-Madison, this time 20-gigabytes worth of data. Many, mostly journalists, are eagerly downloading this next dump. However, at the time of this writing, nobody has finished downloading it yet. None of the journalists have a complete copy, so you aren't seeing any new stories about the contents. It promises the full email spool of the CEO in the file name, but no journalist has yet looked into that mail spool and reported a story. Currently, the most any journalist has is 85% of the dump, slowly downloading the rest at 37-kilobytes/second.Why is that? Is AshMad doing some sort of counter-attack to stop the downloaded (like Sony did)? Or is it overloaded because too many people are trying to download?
No, it's because it hasn't finished seeding.
BitTorrent is p2p (peer-to-peer). You download chunks from the peers, aka. the swarm, not the original source (the tracker). Instead of slowing down as more people join the swarm to download the file(s), BitTorrent downloads become faster -- the more people you can download from, the faster it goes.
But 9 women can't make a baby in 1 month. The same goes for BitTorrent. Continue reading
