Welcome to Technology Short Take #125, where I have a collection of articles about various data center and cloud technologies collected from around the Internet. I hope I have managed to find a few useful things for you! (If not, contact me on Twitter and tell me how I can make this more helpful for you.)
Nothing this time around. I’ll try hard to find something useful for the next Technology Short Take.
The post BGP – the right tool for so many jobs appeared first on Noction.

BGP+SPF Imagine we replace BGP best path selection decision with SPF. BGP+SPF exactly does that. In this post, I will explain why we are looking for alternative protocols for Massively Scale Datacenter.
Although there is no exact answer how many devices should be in the datacenter so datacenter can be considered Massively Scale, but we know 10.000 Racks are not uncommon in these type of datacenter and each rack, when BGP is used as a transport, gets it’s own unique AS number.
Before I explain BGP+SPF, let’s understand why traditional , very well know, OSPF or IS-IS are not used in these type of datacenter.
Answer is scalability. OSPF and IS-IS are chatty protocols and flooding aspect of these protocols are just not suited to very densely meshed connectivities. Yes, these datacenter run on CLOS topology and CLOS is densely meshed topology.
Also, we want to have wide ECMP in these type of datacenter, meaning, between the TOR, Leaf and Spine devices, there are so many equal cost path and we want to utilize them all. OSPF and IS-IS will be limited to number of ways of ECMP.
BGP is very well suited protocol which provides very wide ECMP Continue reading
At Cloudflare, we produce all types of video content, ranging from recordings of our Weekly All-Hands to product demos. Being able to stream video on demand has two major advantages when compared to live video:
Historically, we haven’t had a central, secure repository of all video content that could be easily accessed from the browser. Various teams choose their own platform to share the content. If I wanted to find a recording of a product demo, for example, I’d need to search Google Drive, Gmail and Google Chat with creative keywords. Very often, I would need to reach out to individual teams to finally locate the content.
So we decided we wanted to build CloudflareTV, an internal Netflix-like application that can only be accessed by Cloudflare employees and has all of our videos neatly organized and immediately watchable from the browser.
We wanted to achieve the following when building CloudflareTV:
The tension between iteration and guarantees.

Serverless in the wild: characterizing and optimising the serverless workload at a large cloud provider, Shahrad et al., arXiv 2020
This is a fresh-from-the-arXivs paper that Jonathan Mace (@mpi_jcmace) drew my attention to on Twitter last week, thank you Jonathan!
It’s a classic trade-off: the quality of service offered (better service presumably driving more volume at the same cost point), vs the cost to provide that service. It’s a trade-off at least, so long as a classic assumption holds, that a higher quality product costs more to produce/provide. This assumption seems to be deeply ingrained in many of us – explaining for example why higher cost goods are often implicitly associated with higher quality. Every once in a while though a point in the design space can be discovered where we don’t have to trade-off quality and cost, where we can have both a higher quality product and a lower unit cost.
Today’s paper analyses serverless workloads on Azure (the characterisation of those workloads is interesting in its own right), where users want fast function start times (avoiding cold starts), and the cloud provider wants to minimise resources consumed (costs). With fine-grained, usage based billing, resources used to Continue reading

I’ll admit right up front that this post is more “science experiment” than practical, everyday use case. It all started when I was trying some Cluster API-related stuff that leveraged KinD (Kubernetes in Docker). Obviously, given the name, KinD relies on Docker, and when running Docker on macOS you generally would use Docker Desktop. At the time, though, I was using Docker Machine, and as it turns out KinD doesn’t like Docker Machine. In this post, I’ll show you how to make KinD work with Docker Machine.
By the way, it’s worth noting that, per the KinD maintainers, this isn’t a tested configuration. Proceed at your own risk, and know that while this may work for some use cases it won’t necessarily work for all use cases.
These instructions assume you’ve already installed both KinD and Docker Machine, along with an associated virtualization solution. I’ll be using VirtualBox, but this should be largely the same for VMware Fusion or Parallels (or even HyperKit, if you somehow manage to get that working). I’m also assuming that you have jq installed; if not, get it here.

In these uncertain times we know the Internet is so much more than a tool. It’s a way for people to stay connected, informed, and educated. It shortens distances, spurs innovation, and fosters social and economic development. It empowers us and frees us.
It is a lifeline.
Yet, nearly 50% of the world still remains unconnected – and globally the Internet faces threats, each with the power to undermine the core of its existence. Now more than ever we must ensure the Internet remains open, globally connected, and secure.
The world is counting on it.
As we looked back at our work in 2019, an inspiring theme emerged: a global society driven by the idea that the Internet should be a resource for all, and persevering against odds to make this vision a reality. This society recognizes the Internet’s power as a way to stay in touch, to empower, to enable, and to create. Collectively, we are not just helping to bridge the digital divide, we are taking action to ensure the Internet remains resilient and trusted – a force for good.
