Network Engineer Certification
I prepare for being certified as Network Engineer. This means you have to digest a lot of complicated topics... or you make it fun by using analogies. I bet I will teach you BGP , Interconnects and VPN in the next 10 minutes so that you won't forget it or you get your money back. Let's start like this: Imagine the internet is the highway network connecting towns (datacenters). Then, the cars are network packets driving over it. If highways are the internet, network packets are cars The cars deliver pizza. There are routes where you can drive fast and there are slow routes. Some have four lanes, others are just narrow alleys. That's latency and bandwidth aka throughput . Now I tell you, if I want a pizza, I want it in 10 minutes. Having 5 pizzas after 50 minutes just isn't the same experience although throughput would be the same. Next time you wait for a pizza - think of this blog and agree: nothing beats latency ;) Do you know Lombard street? That's the curviest...
