Google has announced the launch of an open-source automated risk analysis tool in partnership with Netflix named Kayenta.
Kayenta is an adaptation of Netflix’s existing internal canary system that the companies have evolved to be a completely open, extensible and more advanced tool.
Kayenta is able to detect any major issues that developers may experience in rolling out an update or alteration to IT infrastructure, allowing businesses to reduce the risks associated with rolling out such deployments.
“Automated canary analysis is an essential part of the production deployment process at Netflix and we are excited to release Kayenta,” said Greg Burrell, Senior Reliability Engineer at Netflix.
“Our partnership with Google on Kayenta has yielded a flexible architecture that helps perform automated canary analysis on a wide range of deployment scenarios such as application, configuration and data changes.”
Netflix has worked in partnership with open-source cloud delivery platform Spinnaker in the development of Kayenta, allowing a greater ease of access to Kayenta.
“Kayenta allows teams to stay close to their pipelines and deployments without having to jump into a different tool for canary analysis,” Burrell continued. “Spinnaker and Kayenta are fast, reliable and easy-to-use tools that minimize deployment risk, while allowing high velocity at scale.”
Fastly's CDN Reportedly to Blame for Global Internet Outage
A huge outage has brought down a number of major websites around the world. Among those affected are gov.uk, Hulu, PayPal, Vimeo, and news outlets such as CNN, The Guardian, The New York Times, BBC, and Financial Times.
It is thought a glitch at Fastly ─ a popular CDN provider ─ is causing the worldwide issue. Fastly has confirmed it’s facing an outage on its status website but fails to specify a reason for the fault ─ only that the problem isn’t limited to a single data centre and, instead, is a “global CDN disruption” that is potentially affecting the company’s global network.
“We’re currently investigating potential impact to performance with our CDN services,” the firm said.
What is Fastly?
Fastly is a content delivery network (CDN) company that helps users view digital content more quickly. The company also provides security, video delivery, and so-called edge computing services. They use strategically distributed, highly performant POPs to help move data and applications closer to users and deliver up-to-date content quickly.
The firm has been proving increasingly popular among leading media websites. After going public on the New York Stock Exchange in 2019, shares rose exponentially in price, but after today’s outages, Fastly’s value has taken a sharp 5.21% fall and are currently trading at US$48.06.
What are CDNs?
Content delivery networks (CDNs) are a web of small computers, or servers, that link together to collaborate as a single computer. CDNs improve the performance of internet-connected devices by placing these servers as close as possible to the people using those devices in different locations, creating hundreds of points of presence, otherwise known as POPs.
They help minimise delays in loading web page content by reducing the physical distance between the server and the user. This helps users around the world view the same high-quality content without slow loading times.
Without a CDN, content origin servers must respond to every single end-user request. This results in significant traffic to the origin and subsequent load, thereby increasing the chances for origin failure if the traffic spikes are exceedingly high or if the load is persistent.
The Risk of CDNs
Over time, developers have attempted to protect users from the dangers of overreliance through the implementation of load balancing, DDoS (Denial of Service) protection, web application firewalls, and a myriad of other security features.
Clearly, by the state of today’s major website outage, these measures aren’t enough. Evidently, CDNs present a risk factor that is widely underestimated ─ which needs to be rectified with haste. Content delivery networks have become a key part of the global infrastructure, and so it’s imperative that organisations start to figure out risk mitigation strategies to protect companies reliant on the interconnected service from further disruption and disarray.
