The philosophy behind this series is start small and build. With that in mind, I'm going to start with just two EVPN peers, supporting a couple of customer VLANs.
In principle, L2VNI is very similar to the static VXLAN we saw in post 1 of this series. It consists of a Layer 2 segment that can be stretched Continue reading
Before we dive into my experience interning at Cloudflare, let me quickly introduce myself. I am currently a master’s student at the National University of Singapore (NUS) studying Computer Science. I am passionate about building software that improves people’s lives and making the Internet a better place for everyone. Back in December 2021, I joined Cloudflare as a Software Development Intern on the Partnerships team to help improve the experience that Partners have when using the platform. I was extremely excited about this opportunity and jumped at the prospect of working on serverless technology to build viable tools for our partners and customers. In this blog post, I detail my experience working at Cloudflare and the many highlights of my internship.
The process began for me back when I was taking a software engineering module at NUS where one of my classmates had shared a job post for an internship at Cloudflare. I had known about Cloudflare’s DNS service prior and was really excited to learn more about the internship opportunity because I really resonated with the company's mission to help build a better Internet.
I knew right away that this would be a great opportunity and submitted Continue reading
Even though Gartner declared SDN obsolete before plateau in their 2021 Networking Hype Cycle, most vendor marketers never got the memo. Anything that interacts with network devices in any way1 is called an SDN controller. Let’s try to throw some minimal amount of taxonomy into that mess based on how these controllers interact with network elements (physical or virtual).

We’re excited to announce the availability of Network Analytics Logs. Magic Transit, Magic Firewall, Magic WAN, and Spectrum customers on the Enterprise plan can feed packet samples directly into storage services, network monitoring tools such as Kentik, or their Security Information Event Management (SIEM) systems such as Splunk to gain near real-time visibility into network traffic and DDoS attacks.
By creating a Network Analytics Logs job, Cloudflare will continuously push logs of packet samples directly to the HTTP endpoint of your choice, including Websockets. The logs arrive in JSON format which makes them easy to parse, transform, and aggregate. The logs include packet samples of traffic dropped and passed by the following systems:
Note that not all mitigation systems are applicable to all Cloudflare services. Below is a table describing which mitigation service is applicable to which Cloudflare service:
Mitigation System |
Cloudflare Service | ||
|---|---|---|---|
| Magic Transit | Magic WAN | Spectrum | |
| Network-layer DDoS Protection Ruleset | ✅ | ❌ | ✅ |
| Advanced TCP Protection | ✅ | ❌ | ❌ |
| Magic Firewall | Continue reading | ||
