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. …

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
At Cloudflare, our mission is to help build a better Internet. That means making the Internet faster, smarter, safer, but also more cost efficient with the help of our partners. We are always on the lookout for ways to help save customers money. With that goal we announced the Bandwidth Alliance with our founding partners during our Birthday week.
The key concept of the Bandwidth Alliance is to help reduce and in many cases waive data transfer charges, sometimes known as "bandwidth” or “egress” charges, for our mutual customers. We achieve this in partnership with the founding partners through strongly interconnected networks over peered connections. These connections typically occur within the same facility with no middleman. So, neither Cloudflare nor the cloud provider bears incremental costs. Further, we will also use our smart routing system (read details in this technical blog post) to ensure that all our customers’ traffic on participating cloud providers, once their systems are set up, qualify for this offer.
We are proud to announce the following cloud providers and hosting companies have joined the Bandwidth Alliance in committing to zero data transfer fees for Continue reading
Google recently faced a major outage in many parts of the world thanks to a BGP leak. This incident that was caused by a Nigerian ISP – Mainone – occurred on 12 November 2018 between 21.10 and 22.35 UTC, and was identified in tweets from the BGP monitoring service BGPMon, as well as the network monitoring provider Thousand Eyes.
Google also announced the problem through their status page:
We’ve received a report of an issue with Google Cloud Networking as of Monday, 2018-11-12 14:16 US/Pacific. We have reports of Google Cloud IP addresses being erroneously advertised by internet service providers other than Google. We will provide more information by Monday, 2018-11-12 15:00 US/Pacific.
In order to understand this issue, MainOne Inc (AS37282) is peering at IXPN (Internet Exchange Point of Nigeria) in Lagos where Google (AS151169) and China Telecom (AS4809) are also members.
Google (AS15169) advertise their prefixes (more than 500) through the IXPN Route Server, where PCH (Packet Clearing House) collects a daily snapshot of BGP announcements of IXPN. Unfortunately, 212 prefixes (aggregates of those 500+ announcements) from Google were leaked, which was recorded by BGPMon and RIPEstat.
Looking at the RIPE stats it is evident Continue reading
The latest update uses an in-house developed open source version of OpenStack that provides for more agility and a smaller footprint to support edge computing environments.
Last Monday evening — 12 November 2018 — Google and a number of other services experienced a 74 minute outage. It’s not the first time this has happened; and while there might be a temptation to assume that bad actors are at work, incidents like this only serve to demonstrate just how much frailty is involved in how packets get from one point on the Internet to another.
Our logs show that at 21:12 UTC on Monday, a Nigerian ISP, MainOne, accidentally misconfigured part of their network causing a "route leak". This resulted in Google and a number of other networks being routed over unusual network paths. Incidents like this actually happen quite frequently, but in this case, the traffic flows generated by Google users were so great that they overwhelmed the intermediary networks — resulting in numerous services (but predominantly Google) unreachable.
You might be surprised to learn that an error by an ISP somewhere in the world could result in Google and other services going offline. This blog post explains how that can happen and what the Internet community is doing to try to fix this fragility.
Companies are rebranding their SDN products as SD-WAN, dynamic networking, agile networking, or cloud-native network to avoid being part of the SDN hype.
Dell Technologies raised its offer to buy back the stock that tracks Dell’s controlling stake in VMware. Dell previously offered $109 per share. Today the company said it will pay $14 billion, or $120 per share. If shareholders approve this deal, Dell would again become a publicly traded company...
The analyst firm also predicts that by 2023 more than 90 percent of WAN edge infrastructure initiatives will be based on SD-WAN.

Access to the Internet can change people’s lives for the better. This is particularly true when communities take ownership of that access and take full advantage of it to improve their quality of life. This has been the case in the community of Azacualpa, a village in Intibucá in Honduras.
In Azacualpa, the members of the community took on the task of developing and implementing the project “Smart Communities” in order to reduce the digital divide – and preserve their collective memory. The project, which is part of the Internet Society’s Beyond the Net program, finds its origin in “Radio Azacualpa – The Voice of Women,” a community radio station that started in 2017.
By 2018, Smart Communities expanded its reach by impacting the nearly 400 families that inhabit the Azacualpa Valley. To achieve its objectives, the team divided the tasks into three main groups: administrative aspects, project governance, and technical aspects. The three working groups were accompanied by the Honduras Chapter of the Internet Society and the organization Sustainable Development Network Honduras (RDS-HN).
The participation of the community was fundamental. In addition to promoting a consultation with the community, the project facilitators promoted training in communications so that community Continue reading
A convergence of forces in SaaS, IoT, cloud, and mobile have placed unprecedented requirements on businesses to accelerate innovation to meet those rapidly changing preferences. The big don’t eat the small, the fast eat the slow.
The industry has offered several solutions to this acceleration problem – from working harder to outsourcing and devops, but none of those solutions have really offered the levels of acceleration needed. The reason: there is too much friction slowing the art of the possible.
Docker and MuleSoft remove friction in the innovation process, from ideation all the way to deployment. MuleSoft provides a tops down architectural approach, with API-first design and implementation. The Docker approach is bottoms up from the perspective of the application workload with containerization, to both modernize traditional applications and create of new applications.
Marrying those two approaches combined with the platform, tools and methodology, enable both organizations to help your business accelerate faster than ever before. Docker and MuleSoft bridge the chasm between infrastructure and services in a way never before achieved in the industry.
Together, Docker and MuleSoft accelerate legacy application modernization and new application delivery while reducing IT complexity and costs.
