The company is working with VMware on the new Amazon Outposts initiative. Considering VMware’s sister company Dell EMC makes hardware, this could have some interesting implications.
To succeed in SD-WAN, service providers will need to transform their organization and improve their selling skills. Can they do it?
Christoph Jaggi asked me a few questions about using VXLAN with EVPN to build data center fabrics and data center interconnects (including active/active data centers). The German version was published on Inside-IT, here’s the English version.
He started with an obvious one:
What is an active-active data center and why would I want to use an active-active data center?
Numerous organizations have multiple data centers for load sharing or disaster recovery purposes. They could use one of their data centers and have the other(s) as warm or cold standby (active/backup setup) or use all data centers at the same time (active/active).

As TLS 1.3 was ratified earlier this year, I was recollecting how we got started with it here at Cloudflare. We made the decision to be early adopters of TLS 1.3 a little over two years ago. It was a very important decision, and we took it very seriously.
It is no secret that Cloudflare uses nginx to handle user traffic. A little less known fact, is that we have several instances of nginx running. I won’t go into detail, but there is one instance whose job is to accept connections on port 443, and proxy them to another instance of nginx that actually handles the requests. It has pretty limited functionality otherwise. We fondly call it nginx-ssl.
Back then we were using OpenSSL for TLS and Crypto in nginx, but OpenSSL (and BoringSSL) had yet to announce a timeline for TLS 1.3 support, therefore we had to implement our own TLS 1.3 stack. Obviously we wanted an implementation that would not affect any customer or client that would not enable TLS 1.3. We also needed something that we could iterate on quickly, because the spec was very fluid back then, and also something Continue reading
I am a huge believer in “knowledge is key”. Yeah… I know… just reading that statement you are probably saying “well yeah… duh”.
Of course knowledge is key… duh, Fish! We know that! We love knowledge. We are knowledge seekers and we love to learn! I mean… if we didn’t love learning and knowledge why would we be reading this? Okay… got it. You love knowledge. You want to grow your knowledge. I hear you. You are basically saying… bring on the knowledge… max the setting! Got it.
So you most likely extend that desire for knowledge to most of the areas in your life.
For example….
Let’s Continue reading
In order to plan the transition to virtualizing their business, enterprises must consider the required functionality, as well as complexity, cost, and performance.
Part of its database build-out includes a new blockchain managed service.
Efficient packet dropping is a key part of Cloudflare’s distributed denial of service (DDoS) attack mitigations. In this post, we introduce a new tool in our packet dropping arsenal: L4Drop.
We've written about our DDoS mitigation pipeline extensively in the past, covering:
xt_bpf
module, and drops it.Both iptables and Floodgate send samples of received traffic to Gatebot for analysis, and filter incoming packets using rules generated by bpftools. This ends up looking something like this:
This pipeline has served us well, but a lot has changed since we implemented Floodgate. Our new Gen9 and ARM servers use different network Continue reading
Today on the Datanauts we examine why people stretch clusters, the problems this can cause, and alternative design strategies. Our guest is Erik Ableson, owner of the consultancy Infrageeks.
The post Datanauts 152: No More Stretched Clusters! appeared first on Packet Pushers.
Mobile service providers stand to benefit from the growing promise of network slicing, but many are not taking full advantage of the opportunity.
I'm about to embark on a new adventure.
The service mesh proxy was initially developed by Lyft and breezed through the CNCF incubation process a year faster than its fellow graduates.
“Our dominance in the core is why VMware avoids doing PoCs in accounts when we are in a head-to-head fight,” said CEO Dheeraj Pandey.
The company is building a corporate campus in Sunnyvale, California, to provide a home for its more than 1,000 employees in the Valley.
