Heavy Networking 507: Build And Run A Multi-Cloud Network Architecture With Aviatrix (Sponsored)

Cloud networking is a challenge, to say the least. And when you've got deployments running in different public clouds, your challenges multiply. On today's Heavy Networking, sponsor Aviatrix joins us to discuss their cloud networking architecture, which provides a consistent operational environment on top of cloud-native constructs. Our guests are Hammad Alam and Shahzad Ali, both Principal Cloud Solutions Architects at Aviatrix.

Fast Friday Thoughts on Where We Are

It’s been a crazy week. I know the curse is “May you live in interesting times,” but I’m more than ready for things to be less interesting for a while. It’s going to take some time to adjust to things. From a networking perspective, I have a few things that have sprung up.

  • Video conferencing is now a big thing. Strangely, Cisco couldn’t make video the new phone. But when people are stuck at home now we need to do video again? I get that people have a need to see each other face-to-face. But having worked from home for almost seven years at this point I can tell you video isn’t a necessity. It’s a nice option, but you can get a lot accomplished with video calls and regular emails.
  • Along side this is the fact that the push to put more video out there is causing applications to reach their breaking points. Zoom, which is fairing the best out of all of them so far, had some issues on Thursday morning. Tripling the amount of traffic that’s going out and making it very sensitive to delay and jitter is going expose a lot of flaws in the system.

Technology Short Take 125

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.)

BGP+SPF for Hyperscale/Massively Scale Datacenter Deployment

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

Remote Work Isn’t Just Video Conferencing: How We Built CloudflareTV

Remote Work Isn’t Just Video Conferencing: How We Built CloudflareTV
Remote Work Isn’t Just Video Conferencing: How We Built CloudflareTV

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:

  1. It encourages asynchronous communication within the organization
  2. It extends the life time value of the shared knowledge

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:

  • Security: make sure the videos are access controlled and not publicly accessible
  • Authentication: ensure the application can only be accessed by Cloudflare employees
  • Tagging: allow the videos to be categorized so they can Continue reading

Serverless in the wild: characterizing and optimising the serverless workload at a large cloud provider

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

Istio 1.5 Brings a Binary Installer, WASM-Based Extensibility for Envoy

The newest version of the open source version 1.5, comes with a fresh installer to simplify the deployment process, along with a new extension model, based on WebAssembly (WASM), to help proxy servers better filter traffic. The development team behind Istio mark the Envoy‘s, the data plane most frequently used with Istio. “WASM will give developers the ability to safely distribute and execute code in the Envoy proxy — to integrate with telemetry systems, policy systems, control routing and even transform the body of a message,” a web page Linkerd and HashiCorp’s istioctl configuration tool.
