Understanding Merge Point in MPLS Traffic Engineering will help you to understand the MPLS TE – Fast Reroute MP (Merge Point) is the term is used in the context of Fast Reroute. I briefly mentioned from Merge Point in the MPLS Traffic Engineering Fast Reroute Link Protection post earlier and in this […]

I work at a company whose job it is to be attacked. As I’m writing this, an automatic mitigation is fighting two ongoing DDoS attacks. Any machine that’s publicly routable on the internet today can be a vector for attack, and that’s a problem.
Today we want to turn the tables and give you a new way of exposing services to the internet without having them be directly, publicly routable. Meet Cloudflare Warp.

Cloudflare internally runs about 4,000 containers that make up about 1.5K services and applications. Some of these containers need to network with other local containers, and others need to accept connections over the wire.
Every devops engineer knows that bad things happen to good machines, and so our platform operations team tries to hide servers altogether from the internet. There are several ways to do this:
These can be complicated or time consuming, yet none of them are Continue reading

In the real world, tunnels are often carved out from the mass of something bigger - a hill, the ground, but also man-made structures.

In an abstract sense Cloudflare Warp is similar; its connection strategy punches a hole through firewalls and NAT, and provides easy and secure passage for HTTP traffic to your origin. But the technical reality is a bit more interesting than this strained metaphor invoked by the name of similar predecessor technologies like GRE tunnels.
Generic Routing Encapsulation or GRE is a well-supported standard, commonly used to join two networks together over the public Internet, and by some CDNs to shield an origin from DDoS attacks. It forms the basis of the legacy VPN protocol PPTP.
Establishing a GRE tunnel requires configuring both ends of the tunnel to accept the other end’s packets and deciding which IP ranges should be routed through the tunnel. With this in place, an IP packet destined for any address in the configured range will be encapsulated within a GRE packet. The GRE packet is delivered directly to the other end of the tunnel, which removes the encapsulation and forwards the original Continue reading

Long-time readers/followers know that my wife, Crystal, runs a program called Spousetivities. This program organizes events for spouses/partners/significant others at IT industry conferences. This fall is a particularly busy season for Crystal and Spousetivities, as she’ll be organizing events at DockerCon EU, the fall OpenStack Summit, and AWS re:Invent! Here are some details on these upcoming events.
For the first time, Spousetivities will be present at DockerCon EU, taking place this year in Copenhagen, Denmark. There’s a great set of activities planned:
More information is available on the Spousetivities web site; if you’d like to register for any of the events, tickets are available right now.
Spousetivities returns to the fall OpenStack Summit, held this year in beautiful Sydney, Australia. Spousetivities is no stranger to the OpenStack Summits, having supported the OpenStack community for several years now.
Once again, Crystal has arranged a great set of activities in and around Sydney:

A while ago a large airline had a bad-hair day claiming it was caused by a faulty power supply. Not surprisingly, I got a question along the lines of “is that feasible?”
Short answer: Yes. However, someone should be really worried if that wasn’t made up.

Nvidia launched its “Volta” Tesla V100 GPU accelerators back in May, meeting and in some important ways exceeding most of its performance goals, and has been shipping devices, both in PCI-Express and SXM2 form factors, for a few months. Now, the ramp of this complex processor and its packaging of stacked High Bandwidth Memory – HMB2 from Samsung, to be specific – is progressing and the server OEMs and ODMs of the …
