Announcing SSH Access through Cloudflare

Announcing SSH Access through Cloudflare

We held our annual Cloudflare Retreat last week. Over 750 team members from nearly a dozen offices spent three days learning, bonding and some of them got to smash a VPN piñata on stage with a baseball bat. Yes, you read that right.

The latest feature added to Cloudflare Access let us celebrate the replacement of our clunky VPN with a faster, safer way to reach our internal applications. You can now place applications that require SSH connections, like your source control repository, behind Cloudflare Access. We’re excited to release that same feature so that your team can also destroy your own VPN (piñata not included).

Announcing SSH Access through Cloudflare

How we smashed our VPN

We built Access to replace our corporate VPN. We started with browser-based applications, moved to CLI operations, and then began adding a growing list of single sign-on integrations. Our teammates added single sign-on support to the Cloudflare dashboard by combining Access and our serverless product, Workers. We improved the daily workflow of every team member each time we moved another application behind Access. However, SSH connections held us back. Whenever we needed to push code or review a pull request, we had to fall back to our Continue reading

Network operations: A new role for AI and ML

Artificial intelligence (AI) and machine learning (ML) are still viewed with skepticism by many in IT, despite a decades-long long history, continuing advances within academia and industry, and numerous successful applications. But it’s not hard to understand why: The very concept of an algorithm running on a digital computer being able to duplicate and even improve upon the knowledge and judgement of a highly-experienced professional – and, via machine learning, improve these results over time – still sounds at the very least a bit off in the future. And yet, thanks to advances in AI/ML algorithms and significant gains in processor and storage performance and especially the price/performance of solutions available today, AI and ML are already hard at work in network operations, as we’ll explore below.To read this article in full, please click here(Insider Story)

Segment Routing and MPLS VPN

MPLS VPN and Segment Routing. Many people have been asking what are the differences between MPLS VPN and Segment Routing.       In fact, this is a wrong question, because Segment Routing provides transport, MPLS VPN provides Service.   They are not mutually exclusive but they are complementary. In order to create end to …

Don’t Let the Automation Snowflakes Stop You

You know that time of year when snowflakes mean more than description of uniqueness of your networking infrastructure? Some people love to complain about that season and how the weather hinders them, others put on sturdy winter boots and down jackets, change tires on their car, and have tons of fun.

Network automation is no different. Sometimes you can persuade your peers that it makes sense to simplify and standardize the infrastructure to make it easier to abstract and automate (consider that an equivalent of going to a tropic island with shiny beaches and everlasting summer), other times you have to take out your winter boots and make the best out of what you got.

Overload control for scaling WeChat microservices

Overload control for scaling WeChat microservices Zhou et al., SoCC’18

There are two reasons to love this paper. First off, we get some insights into the backend that powers WeChat; and secondly the authors share the design of the battle hardened overload control system DAGOR that has been in production at WeChat for five years. This system has been specifically designed to take into account the peculiarities of microservice architectures. If you’re looking to put a strategy in place for your own microservices, you could do a lot worse than start here.

WeChat

The WeChat backend at this point consists of over 3000 mobile services, including instant messaging, social networking, mobile payment, and third-party authorization. The platform sees between 10^{10} - 10^{11} external requests per day. Each such request can triggers many more internal microservice requests, such that the WeChat backend as a whole needs to handle hundreds of millions of requests per second.

WeChat’s microservice system accommodates more than 3000 services running on over 20,000 machines in the WeChat business system, and these numbers keep increasing as WeChat is becoming immensely popular… As WeChat is ever actively evolving, its microservice system has been undergoing fast iteration of service updates. For instance, Continue reading

Spectrum shake-up to deliver more Wi-Fi, connections

The United States' Federal Communications Commission (FCC) wants to expand available spectrum in order to increase bandwidth for connected devices, such as IoT and broadband data, including those communicating via Wi-Fi. One reason is because ISPs want to get into wireless, and they are putting pressure on. The expansion, however, will be good for all Internet of Things (IoT), too.A number of significant unlicensed bandwidth blocks are, or will be, available, including at 6GHz, 5.9GHz, and 3.5GHz. Potential stumbles include that interference mitigation needs to be resolved in a couple instances.[ Also read: Wi-Fi 6 is coming to a router near you. | Get regularly scheduled insights: Sign up for Network World newsletters. ] 6GHz In the first block, the FCC is proposing making available a large 1200 megahertz of spectrum in the 6GHz band for devices, including IoT sensors, and Wi-Fi, which predominantly uses 2.4GHz and 5.8GHz now.To read this article in full, please click here

China Navigating The Homegrown Waters For Exascale

A major part of China’s several initiatives to build an exascale-class supercomputers has been the country’s determination to rely mostly on homegrown technologies – from processors and accelerators to interconnects and software – rather than turn to vendors outside of its borders, particularly those from the United States. …

Bandwidth Alliance Partners - Exciting Choices

We are tremendously excited about the value our Bandwidth Alliance partner ecosystem adds to our customers. We’re on a mission to help make the internet a better place; and ensuring everyone can access cloud resources at zero-egress rates supports that mission in many ways. It’s an easy way for our clients to build modern, cloud-centric applications without the design constraint and financial burden of egress fees.

The cloudflare bandwidth alliance partner landscape continues to grow, and incorporate a diverse group of partners, with today’s second wave announcement.  With over a dozen different partners, the range of choices can quickly become overwhelming. And, while these are all high-quality platforms which we are happy to recommend to our clients - their important differences will help determine the best fit for you, the customer.

In this post, I’ll lay out some of Cloudflare’s approach to this solution design question through the lens of a large client we recently worked with. We apply this approach across our full range of products and services, including many use cases far different from the Storage need we’ll dig into in this post. I hope that this can help all of our clients, or anyone else interested, mirror Continue reading
