The startup raised $6 million in its Series A round, bringing its total funding to $7.8 million. Axonize’s IoT orchestration platform is based on Microsoft Azure and is built for IoT service providers.
Last month, Docker turned five! In celebration of this milestone, we turned the spotlight on our amazing global community of customers, users, Community Leaders, Captains, mentors, partners and sponsors, and asked them to reflect on their Docker learning journey. Everyone came together to celebrate how far they had come, think about where they would like to go and take that next step towards reaching their goal.
We had a lot of fun during the #dockerbday with the Quebec #Docker community! Thanks to @ingeno for sponsoring the event, @tnazare for the cake and for being an awesome mentor! #dockerselfie #DockerQC pic.twitter.com/YZZNkWfWjq

There was an important development this month with the launch of Cloudflare’s new 1.1.1.1 DNS resolver service. This is a significant development for several reasons, but in particular it supports the new DNS-over-TLS and DNS-over-HTTPS protocols that allow for confidential DNS querying and response.
Why 1.1.1.1?
Before we get to that though, Cloudflare joins Google’s Public DNS that uses 8.8.8.8 and Quad9 DNS that uses 9.9.9.9, by implementing 1.1.1.1 as a memorable IP address for accessing its new DNS service. IP addresses are generally not as memorable as domain names, but you need access to a DNS server before you can resolve domain names to IP addresses, so configuring numbers is a necessity. And whilst a memorable IP address might be cool, it’s also proved important recently when DNS resolvers have been blocked or taken down, requiring devices to be pointed elsewhere.
The 1.1.1.1 address is part of the 1.1.1.0 – 1.1.1.255 public IP address range actually allocated to APNIC, one of the five Regional Internet Registries, but it has been randomly used as an address for Continue reading
Supercomputers keep getting faster, but they are keep getting more expensive. This is a problem, and it is one that is going to eventually affect every kind of computer until we get a new technology that is not based on CMOS chips.
The general budget and some of the feeds and speeds are out thanks to the requests for proposal for the “Frontier” and “El Capitan” supercomputers that will eventually be built for Oak Ridge National Laboratory and Lawrence Livermore National Laboratory. So now is a good time to take a look at not just the historical performance of capability …

Today we are introducing Spectrum, which brings Cloudflare’s security and acceleration to the whole spectrum of TCP ports and protocols for our Enterprise customers. It’s DDoS protection for any box, container or VM that connects to the internet; whether it runs email, file transfer or a custom protocol, it can now get the full benefits of Cloudflare. If you want to skip ahead and see it in action, you can scroll to the video demo at the bottom.
The core functionality of Spectrum is its ability to block large DDoS attacks. Spectrum benefits from Cloudflare’s existing DDoS mitigation (which this week blocked a 900 Gbps flood). Spectrum’s DDoS protection has already been battle tested. Just soon as we opened up Spectrum for beta, Spectrum received its first SYN flood.
One of Spectrum's earliest deployments was in front of Hypixel’s infrastructure. Hypixel runs the largest minecraft server, and because gamers can be - uh, passionate - they were one of the earliest targets of the terabit-per-second Mirai botnet. “Hypixel was one of the first subjects of the Mirai botnet DDoS attacks and frequently receives large attacks. Before Spectrum, we had to rely on unstable services & techniques Continue reading

Today we are introducing Spectrum: a new Cloudflare feature that brings DDoS protection, load balancing, and content acceleration to any TCP-based protocol.

Soon after we started building Spectrum, we hit a major technical obstacle: Spectrum requires us to accept connections on any valid TCP port, from 1 to 65535. On our Linux edge servers it's impossible to "accept inbound connections on any port number". This is not a Linux-specific limitation: it's a characteristic of the BSD sockets API, the basis for network applications on most operating systems. Under the hood there are two overlapping problems that we needed to solve in order to deliver Spectrum:
Cloudflare’s edge servers have an almost identical configuration. In our early days, we used to assign specific /32 (and /128) IP addresses to the loopback network interface[1]. This worked well when we had dozens of IP Continue reading

얼마전 우리는 Spectrum을 발표하였습니다: 어떤 TCP 기반의 프로토콜이라도 DDoS 방어, 로드밸런싱 그리고 컨텐츠 가속을 할 수 있는 새로운 Cloudflare의 기능입니다.

Spectrum을 만들기 시작하고 얼마 되지 않아서 중요한 기술적 난관에 부딛히게 되었습니다: Spectrum은 1부터 65535 사이의 어떤 유효한 TCP 포트라도 접속을 허용해야 합니다. 우리의 리눅스 엣지 서버에서는 "임의의 포트 번호에 인바운드 연결을 허용"은 불가능합니다. 이것은 리눅스만의 제한은 아닙니다: 이것은 대부분 운영 체제의 네트워크 어플리케이션의 기반인 BSD 소켓 API의 특성입니다. 내부적으로 Spectrum을 완성하기 위해서 풀어야 하는 서로 겹치는 문제가 둘 있었습니다:
Cloudflare의 엣지 서버는 거의 동일한 구성을 갖고 있습니다. 초창기에는 루프백 네트워크 인터페이스에 특정한 /32 (그리고 /128) IP 주소를 할당하였습니다[1]. 이것은 수십개의 IP주소만 갖고 있었을 때에는 잘 동작 하였지만 더 성장함에 따라 확대 적용하는 것에는 실패하였습니다.
그때 "AnyIP" 트릭이 등장하였습니다. AnyIP는 단일 주소가 아니라 전체 IP 프리픽스 (서브넷)을 루프백 인터페이스에 할당하도록 해 줍니다. 사실 AnyIP를 많이 사용하고 있습니다: 여러분 컴퓨터에는 루브백 인터페이스에 Continue reading
