Introducing Cache Analytics

Today, I’m delighted to announce Cache Analytics: a new tool that gives deeper exploration capabilities into what Cloudflare’s caching and content delivery services are doing for your web presence.

Caching is the most effective way to improve the performance and economics of serving your website to the world. Unsurprisingly, customers consistently ask us how they can optimize their cache performance to get the most out of Cloudflare.

With Cache Analytics, it’s easier than ever to learn how to speed up your website, and reduce traffic sent to your origin. Some of my favorite capabilities include:

• See what resources are missing from cache, expired, or never eligible for cache in the first place
• Slice and dice your data as you see fit: filter by hostnames, or see a list of top URLs that miss cache
• Switch between views of requests and data Transfer to understand both performance and cost

Cache Analytics is available today for all customers on our Pro, Business, and Enterprise plans.

In this blog post, I’ll explain why we built Cache Analytics and how you can get the most out of it.

Why do we need analytics focused on caching?

How to Develop Inside a Container Using Visual Studio Code Remote Containers

This is a guest post from Jochen Zehnder. Jochen is a Docker Community Leader and working as a Site Reliability Engineer for 56K.Cloud. He started his career as a Software Developer, where he learned the ins and outs of creating software. He is not only focused on development but also on the automation to bridge the gap to the operations side. At 56K.Cloud he helps companies to adapt technologies and concepts like Cloud, Containers, and DevOps. 56K.Cloud is a Technology company from Switzerland focusing on Automation, IoT, Containerization, and DevOps.

Jochen Zehnder joined 56K.Cloud in February, after working as a software developer for several years. He always tries to make the lives easier for everybody involved in the development process. One VS Code feature that excels at this is the Visual Studio Code Remote – Containers extension. It is one of many extensions of the Visual Studio Remote Development feature.

This post is based on the work Jochen did for the 56K.Cloud internal handbook. It uses Jekyll to generate a static website out of markdown files. This is a perfect example of how to make lives easier for everybody. Nobody should know how to install, Continue reading

On the ‘net: One Size Never Fits All

You might have seen, in the recent pandemic, advertisements for masks where “one size fits all.” You might see the same sort of thing for gloves, or maybe even flip-flops—but what you will rarely find, in the networking world, is anything that fits all. It is, in fact, challenging to explain the plethora of protocols designed and deployed by the networking community to solve any possible problem.

Cumulus Networks’ President and Chief Product Officer, Partho Mishra, on the NVIDIA-Cumulus acquisition.

With the acquisition of Cumulus Networks and Mellanox by NVIDIA, there have been a lot of questions regarding the strategic focus of the new networking business unit at NVIDIA and the future of the open networking approach that Cumulus Networks pioneered.

The open networking journey continues

Mellanox and Cumulus are absolutely committed to open networking and allowing our customers to pick best-of-breed solutions. Cumulus will continue to support all of the hardware platforms on our Hardware Compatibility List (HCL) and to add new hardware platforms from multiple hardware partners to the HCL. Mellanox already offers multiple Network-Operating-Systems — ONYX, SONIC, Cumulus Linux – to customers and this continues unchanged. In terms of total code commits to open source projects, such as FRR, SONIC and the Linux networking kernel, Cumulus+Mellanox have contributed very heavily in the past and will continue to do so in the future. This is an integral part of our DNA.

Check out the latest episode of Kernel of Truth to hear me and Amit Katz discuss more about the future of open networking including how SONIC and Cumulus Linux will work together, what happens to open “campus” networking and the next generation of in-band telemetry.

Using kubectl via an SSH Tunnel

In this post, I’d like to share one way (not the only way!) to use kubectl to access your Kubernetes cluster via an SSH tunnel. In the future, I may explore some other ways (hit me on Twitter if you’re interested). I’m sharing this information because I suspect it is not uncommon for folks deploying Kubernetes on the public cloud to want to deploy them in a way that does not expose them to the Internet. Given that the use of SSH bastion hosts is not uncommon, it seemed reasonable to show how one could use an SSH tunnel to reach a Kubernetes cluster behind an SSH bastion host.

If you’re unfamiliar with SSH bastion hosts, see this post for an overview.

To use kubectl via an SSH tunnel through a bastion host to a Kubernetes cluster, there are two steps required:

1. The Kubernetes API server needs an appropriate Subject Alternative Name (SAN) on its certificate.
2. The Kubeconfig file needs to be updated to reflect the tunnel details.

Ensuring an Appropriate SAN for the API Server

As is the case with just about any TLS-secured connection, if the destination to which you’re connecting with kubectl doesn’t match any of Continue reading

Internet Society and Alliance for Affordable Internet Partner to Promote Community Networks and Expand Access for All

The Internet Society and the Alliance for Affordable Internet (A4AI), an initiative of the World Wide Web Foundation, have entered into a Memorandum of Understanding (MoU) to further their existing partnership to collaborate on promoting community networks to expand meaningful connectivity, and other areas of joint interest.

A4AI is a global coalition working to drive down the cost of Internet access in low- and middle-income countries through policy and regulatory reform. The Internet Society is a member of A4AI, and the two organizations share a vision of an open, globally connected, secure, and trustworthy Internet for everyone.

Both organizations have emphasized the importance of solid research, capacity building, and advocacy to develop the policies needed to reduce the cost to connect and enable everyone, everywhere to access Internet connectivity. A4AI and ISOC believe community networks provide a sustainable solution to address connectivity gaps that exist in underserved urban, remote, and rural areas around the world.

This MoU formalizes a longstanding relationship between the two organizations. In the past, we’ve worked together to collaborate on common policy and regulatory objectives across numerous UN and international fora to promote and advocate for the expansion of public access solutions through community networks, Continue reading

EVPN: The Great Unifying Theory of VPN Control Planes?

I claimed that “EVPN is the control plane for layer-2 and layer-3 VPNs” in the Using VXLAN and EVPN to Build Active-Active Data Centers interview a long long while ago and got this response from one of the readers:

To me, that doesn’t compute. For layer-3 VPNs I couldn’t care less about EVPN, they have their own control planes.

Apart from EVPN, there’s a single standardized scalable control plane for layer-3 VPNs: BGP VPNv4 address family using MPLS labels. Maybe EVPN could be a better solution (opinions differ, see EVPN Technical Deep Dive webinar for more details).

COVID-19 fallout: Q1 enterprise data center sales dip, but public cloud grows

This should come as no surprise, but spending on data-center hardware and software dipped in Q1 and cloud sales grew, but neither as much as you would think.Q1 figures from Synergy Research Group show that spending on enterprise software and hardware shrank globally by a modest 2% year on year to $35.8 billion, with the biggest non-cloud players, such as Microsoft, Dell, HPE, Cisco and VMware, down 4%.[Get regularly scheduled insights by signing up for Network World newsletters.] When it comes to public cloud infrastructure, sales rose 3% to $9.66 billion year on year.
