Waiting Room ajoute la prise en charge d'hôtes et de chemins d'accès multiples, offrant une protection plus étendue et des configurations multilingues

Cloudflare Waiting Room protège les sites contre les surcharges liées aux pics de trafic en transférant l'excédent de visiteurs vers une salle d'attente virtuelle, entièrement personnalisable, dans laquelle les visiteurs sont admis dynamiquement, au fur et à mesure que des places se libèrent. Au lieu d'afficher des pages d'erreur ou de proposer une expérience insatisfaisante de l'affichage des pages du site, Waiting Room permet aux clients de prendre le contrôle de l'expérience de leurs utilisateurs finaux pendant les pics de trafic ingérables.

L'une des principales décisions que prennent les clients lors de la configuration d'une salle d'attente consiste à sélectionner les pages que protégera celle-ci. Jusqu'à présent, les clients pouvaient sélectionner un nom d'hôte et un chemin d'accès lors de la désignation des pages protégées par une instance de Waiting Room. Aujourd'hui, nous sommes ravis d'annoncer que Waiting Room propose désormais la prise en charge de combinaisons de noms d'hôtes et de chemins d'accès multiples pour une salle d'attente unique, offrant ainsi aux clients davantage de flexibilité et une prise en charge plus étendue des sites, sans interruption des flux des utilisateurs finaux.Cette nouvelle fonctionnalité est accessible à tous les clients Enterprise ayant préacheté Waiting Room.

Seeding Ansible Automation Platform Content At Installation Time

In a previous blog, I announced the tech preview of containerized Red Hat Ansible Automation Platform. With that we introduced a new feature to enable you to pre-seed configuration and content at installation time. This blog will take you through how that works.

At Red Hat, we are very lucky to have some super talented people. Some of these great folks have worked tirelessly on producing Ansible Content Collections for managing configuration within the platform. Using this as the foundation, we have wrapped enablement around that to provide a fully automated way of doing this, in a seamless fashion.

 

The Benefits

Many people today already use a configuration-as-code (CaC) approach to managing the platform and laying down standards for their users. If that’s your case, then this simply extends and simplifies this capability.

If this is a new concept to you, then these examples may be of interest:

• Standardize your user’s out of the box (OOTB) experience, in one go, at installation time.
  • Are there platform artifacts that you always need to apply to each and every installation? Define those as code and simply point the installation at that code and it will pre-configure the platform

• The ability Continue reading

2023년 10월 4일 1.1.1.1 조회 실패

2023년 10월 4일, Cloudflare에서는 DNS 확인 문제를 겪었으며, 이 문제는 UTC 07:00에 시작하여 UTC 11:00에 끝났습니다. 1.1.1.1 또는 Warp, Zero Trust 등의 제품 또는 1.1.1.1을 사용하는 타사 DNS 확인자를 사용하는 사람 중 일부는 유효한 쿼리에 대해 SERVFAIL DNS 응답을 받았을 수도 있습니다. 이번에 서비스가 중단되어 정말 죄송합니다. 이번 서비스 중단은 공격이 아니라 내부 소프트웨어 오류로 발생했습니다. 이 블로그에서는 어떤 장애였는지, 장애가 왜 발생했는지, 이런 일이 다시 발생하지 않도록 우리가 무엇을 하고 있는지 설명하겠습니다.

배경

도메인 네임 시스템(DNS)에서 모든 도메인 네임은 DNS 영역 내에 존재합니다. 이 영역은 함께 제어되는 도메인 이름과 호스트 이름의 모음입니다. 예를 들어, Cloudflare에서는 도메인 이름 cloudflare.com을 관리하며, 우리는 이를 "cloudflare.com" 영역이라고 부릅니다. .com의 최상위 도메인(TLD)은 타사 소유이며 "com" 영역에 있습니다. TLD는 cloudflare.com에 접속하는 방법에 대한 지침을 제공합니다. 모든 TLD 위에는 루트 영역이 있으며, 이 영역은 TLD에 도달하는 방법에 대한 지침을 제공합니다 . 즉, 루트 영역은 다른 모든 도메인 이름을 확인할 수 있는 중요한 영역입니다. DNS의 다른 중요한 부분과 마찬가지로 루트 영역은 DNSSEC로 서명되며, 이는 루트 영역 자체에 암호화 서명이 포함되어 있음을 의미합니다.

루트 영역은 루트 서버에 게시되지만, 루트 서버에 연결할 수 없는 경우에도 루트 영역의 정보를 계속 사용할 수 있도록 DNS 운영자가 루트 영역의 Continue reading

Migration Coordinator – Selecting the migration mode

Migration Coordinator is a fully supported free tool, that is built into NSX Data Center, that is designed to help customers migrating from NSX for vSphere to NSX (aka NSX-T).  NSX-T 2.4, was the first release, about three years back, to introduce Migration Coordinator with couple of modes to enable migrations. Today, migration coordinator supports over 10 different ways to migrate from NSX for vSphere to NSX.

The last three blogs in this series covered the various modes available along with the pros and cons of each mode.

1. Migration Coordinator: Approaches and Modes
2. Migration Coordinator – In Place Migration Modes
3. Migration Coordinator – Lift and Shift Migration Modes

This blog will focus on selecting the migration mode based on your requirements.

Terms, Tools and Modes

Before digging into how to go about selecting the right mode for the migration, let’s take a quick look at some of the terms, tools and high-level view of the modes available for migration, when leveraging Migration Coordaintor.

The following table summarizes some of the key terms used in regard to migrations:

Terms	Description
In-place	Migrate using the same hardware
Lift and Shift	Migrate to either new or repurposed hardware.

BrandPost: Selecting Cybersecurity Solutions for Hybrid and Hyperscale Data Centers

Hybrid and hyperscale data centers need cybersecurity solutions that won’t hinder an organization from doing its business. However, there are far too many data center environments that still rely on outdated traditional firewalls. Because these legacy firewalls underperform and underserve, IT teams are being pushed into making perilous trade-offs between security and performance. Since there is much at stake—and so little expert guidance available—choosing the right solutions can be extremely difficult for organizations. Below are eight key factors for IT leadership to consider when securing their modern data center infrastructure:To read this article in full, please click here

Data centers aren’t ready for AI, Schneider warns

Schneider Electric is warning the demands of power and cooling for AI are beyond what standard data center designs can handle and says new designs are necessary.That may be expected from a company like Schneider, which makes power and cooling systems used in data centers. But it doesn’t mean Schneider isn't correct. AI is a different kind of workload than standard server-side applications, such as databases, and the old ways just don’t cut it anymore.Schneider's white paper notes that AI needs ample supply of three things: power, cooling, and bandwidth. GPUs are the most popular AI processors and the most power intensive. Whereas CPUs from Intel and AMD draw about 300 to 400 watts, Nvidia’s newest GPUs draw 700 watts per processor and they are often delivered in clusters of eight at a time.To read this article in full, please click here

Announcing General Availability for the Magic WAN Connector: the easiest way to jumpstart SASE transformation for your network

Today, we’re announcing the general availability of the Magic WAN Connector, a key component of our SASE platform, Cloudflare One. Magic WAN Connector is the glue between your existing network hardware and Cloudflare’s network — it provides a super simplified software solution that comes pre-installed on Cloudflare-certified hardware, and is entirely managed from the Cloudflare One dashboard.

It takes only a few minutes from unboxing to seeing your network traffic automatically routed to the closest Cloudflare location, where it flows through a full stack of Zero Trust security controls before taking an accelerated path to its destination, whether that’s another location on your private network, a SaaS app, or any application on the open Internet.

Since we announced our beta earlier this year, organizations around the world have deployed the Magic WAN Connector to connect and secure their network locations. We’re excited for the general availability of the Magic WAN Connector to accelerate SASE transformation at scale.

When customers tell us about their journey to embrace SASE, one of the most common stories we hear is:

We started with our remote workforce, deploying modern solutions to secure access to internal apps and Internet resources. But now, we’re looking at Continue reading
