African traffic growth and predictions for the future
Looking back at our historical data, we realized how much the Internet and Cloudflare grew. With more than 150 datacenters, 10 percent of web-based applications, customers everywhere around the world, from the tiny islands in the Pacific to the big metropolises, we have an Internet landscape of almost every country and continent.
Cloudflare’s mission is to help build a better Internet. To do that we operate datacenters across the globe. By having datacenters close to end user we provide a fast, secure experience for everyone. Today I’d like to talk about our datacenters in Africa and our plans to serve a population of 1.2 billion people over 58 countries.
Internet penetration in developed countries skyrocketed since the 2000s, Internet usage is growing rapidly across Africa. We are seeing a 4% to 7% increase in traffic month on month. As of July 2018, we have 8 datacenters on the African Continent:

rbenv is a utility for installing multiple ruby versions on a host machine. Using rbenv allows you to install ruby in a path you have ownership over so you can install gems without having to have sudo or root privileges. rbenv also allows you to target the exact ruby version in development...Apstra Hires Former VeloCloud Exec, Tells Cisco to Bring It

6 Recommendations for a Future-Proof Hybrid Cloud Strategy
Hybrid cloud computing for high performance computing is quickly becoming commonplace, but there are certain challenges that CIOs must overcome in order to reap all the benefits.
New to the INE Course Library – Implementing Inter-VLAN Routing
This course covers the basics of implementing inter-VLAN routing by explaining the theory behind two common methodologies, as well as their implementation on Cisco routers and switches. By the end of this course students will be able to explain the differences between “Router-On-A-Stick” and “Switched Virtual Interfaces,” as well as how to implement inter-VLAN routing using either of these techniques.
Why You Should Watch:
Virtually all organizations that implement VLANs into their switched networking topologies also need to know how to route IP traffic between those VLANs. Knowing the techniques available to accomplish this kind of routing is essential whether you are managing a network, or simply pursuing a networking certification (like the Cisco CCNA).
Many learners are confused about the differences between VLANs and SVIs (Switched Virtual Interfaces) as well as their inter-relationship. This course is meant to clarify any confusion you may have between those differences, and teach you both the theory and implementation (utilizing Cisco IOS software) of Inter-VLAN Routing.
Who Should Watch:
This course is intended for anyone wanting to learn about inter-VLAN routing with an emphasis on the techniques to do so using Cisco routers and switches. A basic familiarity with the Cisco IOS command Continue reading
IXP Graphs are an Eyesore
Too many IXPs (and networkers in general) are using horrible outdated methods of graphing data. These are an ugly eyesore, and should be updated to something from this century. Big IXPs in particular have no excuse: they have the resources to do better.
IXPs: Invest, Spend, Drop Prices?
Two years ago Dave Temkin from Netflix presented at NANOG 67, talking about The Real Cost of Public IXPs (warning: PDF).
This caused a bit of a stir. As El Reg put it:
[According to Dave Temkin] The internet exchange industry is ripping customers off, charging too much for features people don’t need, and spending millions on staff salaries, unnecessary marketing and social events.
You can argue amongst yourselves as to how much IXPs should invest, how closely their port prices should track transit costs, etc. Or maybe you just like all the free drinks, dammit.
I think that if they’re going to spend money rather than reduce prices, they should spend it on something I care about: Data visualization. Most IXPs traffic graphs are an eyesore, they’re outdated, and it’s time they were fixed.
Ugly Eyesores
Here’s some typical traffic graphs from some of the biggest IXPs in the world:

[Sponsored] Short Take – Forward Networks
In this sponsored Network Collective Short Take, Brandon Heller, Co-Founder and CTO of Forward Networks, joins Network Collective to talk about how network verification and modeling are empowering network operators to increase efficiency, reduce mistakes, and shorten the mean-time-to-resolution when troubleshooting network issues.
Forward Networks does this through a complete and accurate mathematical model of the way your network operates, allowing you to quickly assess traffic flows and operational issues in your network without needing to query multiple devices manually.
Having an accurate model of your network also empowers you to validate changes before ever touching your production environment, giving you confidence that the change you are implementing will achieve the desired outcome.
For more technical details, short demo videos, and a chance to try Forward on your network to gain greater insight, head on over to http://forwardnetworks.com/collective.
