Linode 开始免费提供 DDoS 防护服务

近日，Linode 官方宣布，在全球范围11个数据中心提供免费 DDoS 防护服务，减轻 DDoS 攻击对客户造成的影响。

不断升级的 DDoS 攻击，每年造成上千亿美金的经济损失，Linode 为了应对这些攻击，花了大资金研发出减轻 DDoS 攻击的办法，成为行业内最先进的网络防护办法之一。

Linode 先进的 DDoS 防护能力能够承受比以往任何时候都大的攻击，并且不会增加网络延迟，也不会通过算法将客户流量路由到第三方。 当检测到威胁时，Linode 会在攻击到达了客户的基础架构前进行过滤，然后将增加的流量分配到其全球光纤主干网中。这项新功能能解决多种 DDoS 攻击方式，包括 UDP，SYN，HTTP floods 等。

Linode 提供的免费 DDoS 防护服务，变相降价（Vultr DDoS 防护需要 $10 美金/月）。

Linode 官方公告中也提到，他们将会上线 Cloud Firewall，网络防火墙，目前 Vultr 和 DigitalOcean 都已经有这个功能。

官方原文：Linode Launches Free Advanced DDoS Protection Across Its Global Network

Powerful combination of automated threat technology and expansive mitigation capacity can block or defer large scale DDoS attacks

PHILADELPHIA, January 24, 2020 — Linode, the world’s largest independent cloud provider, today announced advanced protection across its global network of 11 data centers to mitigate the impact of pervasive and costly distributed denial of service (DDoS) attacks. Like it has done with other critical services, Linode is making this additional layer of protection free for every one of its customers, no matter how big or small.

Increasing levels of DDoS attacks at every layer of the Internet have made DDoS protection a mandatory first line of defense for businesses running workloads in the cloud. These attacks have caused hundreds of billions of dollars in economic loss globally and remain a significant challenge for many cloud providers and their customers. Linode has been responding to these ongoing threats by investing heavily in building out advanced DDoS mitigation capabilities that today represent one of the most advanced network protection measures in the industry.

“DDoS attacks are a clear and present danger for anyone doing business in the cloud today,” said Dan Spataro, Director of Infrastructure at Linode. “We’ve invested heavily in the capacity to mitigate these attacks across our global network and built the predictive technologies necessary to automatically detect and neutralize threats at our network edge before they can impact service. Coupled with our soon to be released Cloud Firewall solution, we’re giving customers the enhancements they need to scale with confidence.”

Volumetric attacks are the most common type of DDoS attack, the virtual equivalent to intentionally causing a traffic-jam by flooding a highway with more cars than it can handle. Linode’s advanced DDoS protection has the capacity to withstand attacks larger than any seen in the industry to date, with no increased latency and no routing of a customer’s traffic to a third party, by applying real-time behavioral algorithms that detect and block volumetric traffic before it reaches a customer’s infrastructure. When a threat is detected, Linode blocks the attack inline, then distributes the increased traffic across its global fiber backbone. The new capability was designed to further minimize any impact to a customer’s services by addressing a broad range of DDoS attack methods, including UDP, SYN, HTTP floods, and more.

The addition of advanced DDoS mitigation sets Linode apart from other alternative cloud providers that charge for or do not offer this level of protection.

“Linode has been known for the quality and performance of the network it has built over the past 16 years,” said Liam Eagle, research vice president at 451 Research. “Continuing to add capabilities like DDoS protection is how smaller, customer focused cloud providers are giving developers and the companies they work for viable alternatives to the large public cloud providers.”
