Our network is full layer 3 Clos Leaf/Spine. We'd much prefer something with network advertisements (OSPF/BGP) or SDN. Layer 2 stuff is OK for labs, but I don't know anyone building out layer 2 networks any more.

We were running with shorter TTL's on service records, and upstream apps threw rashes of errors when queries timed out.

We're running Kubernetes for minor amounts of traffic in production, but we're still not in a great place due to a few limitations in running Kubernetes on your own gear. I know that people like to talk about cost savings and stuf

+1 for "regular" Ceph. Don't bother with that rook stuff. Just setup a regular Ceph cluster and go. Kubernetes handles its stuff and a (much more reliable and stable) Ceph cluster handles blocks and files.

We've been using CoreDNS for a bit now, and it's much better than KubeDNS. We found that KubeDNS would time out and drop requests from time to time. No such issues with CoreDNS. Would recommend (at least from a reliability standpo

This guidance is beyond suspect. It falls into the category of "drink 8 glasses of water a day." Doctors parrot it, but they have no foundation for saying this and no one knows when/why they started saying it. But they all sa

Lowers the cost? While not paramount in a non-burner scenario, lower cost is generally preferable.

Addiction is a possible effect of willingly taking drugs (as the person before you was stating). I'm not saying that people don't have demons and everyone has their own way of coping, but you need to take drugs to be addicted. Tha

Heroin is basically legal in San Francisco. Public injection is 100% tolerated by police (not by most citizens though). Police won't arrest you for buying heroin. DA certainly won't prosecute even if you are arrested. Hell, you ca

Still trying to understand the ToR case. They're pretty basic with enough ports, BGP, and mgmt agents to do just what you need. That said, these things are _stupid_ cheap now. The Quanta switches that AWS used/use couldn't ha

Google (corporate? maybe not Cloud) and Facebook still buy a lot of vendor gear, though it's mostly Arista. Google and FB have investments in running their own whitebox gear, but they use their own purchasing size as a carrot with comp

Google offered all free IPv6 peering to all major transit carriers. Cogent turned them down and said, no, you need to pay Cogent for this. They were the only carrier to do this. So Cogent uses other transit carriers to reach Google. If you&

Well, they tried to do their own thing outside of the app store. You'll need someone working on reachability, deployments, performance, security, monitoring, etc. Or just use the Appstore.

That's a shame. They should have picked up someone for this around employee number 8-10.

Eh, I was never impressed with Level3. Their network was huge, and they generally had zero clue what was happening on it. Big networks aren't always better. Level3 got to be huge by running up massive amounts of debt and pricing servic

They are, but even the larger players get into peering disputes with eyeball networks. Level3 and Comcast had a huge peering spat a few years ago (via Netflix). Everyone's ports run hot with China Telecom and China Unicom. It's al

Also lol at "support ticket with your ISP." We're talking about major tier 1 carriers here.

Fair enough, I guess visibility, in the one thing everyone's looking at in a crisis, is good.

Snark or not, the traffic is filtered upstream before your handoff. If you pick your carriers well, there's not a problem. Many carriers have turned upstream filters into a product. NTT's DPS Lite springs to mind. This just comes

Meh, or just block UDP to your networks that have no reason to run UDP. Every carrier will do upstream ACL's these days. 5 years ago that wasn't the case. These days, they all do. Some free, some charge. re: chat ops vs a web page

They lease in carrier hotels from people like Equinix, Interxion, and Coresite for edge connections and peering. They also buy on the wholesale market taking over entire buildings and campuses. DFT had a great business model. Leasing out en

No, yeah. Dupont said that 15% of their revenues came from Facebook. It was listed as a risk in their annual report. FB and et al do still build their own DC's. Especially where municipalities drop their pants and offer huge tax breaks

It adds 20 and 30 year lease stability to DRT's portfolio. DFT still operates under the DFT name for now. Just like telx which was also a DRT acquisition.

by scurvy 9y ago
Google, Facebook, Apple, Salesforce are listed as customers of large wholesalers like DFT. Like you mentioned, it's easier to get someone else to build and run the building (to your specs). Plus there is some anonymity too.

Technically, almost no one builds their own datacenters at this point. The new stuff is built by wholesalers like Dupont Fabros, and companies like Apple sign 20 year leases to be the sole tenant. Same goes for Facebook. The tenant dictates

There should be! Any serious consumer of cloud storage has an abstraction layer that let's you store new data in arbitrary locations on site or across public clouds. Companies frequently write their own middleware connectors.

Nah it's all fairly off the shelf at this point. You can run Ceph on top of server designs from Quanta and already be at near parity with S3 under your own roof. You just have to want to do it; something I bet Apple doesn't care a

Indeed. There are also right ways to setup anycasting and wrong ways. Right way: 1-2 major Tier1 carriers across all of your PoPs with local peering for regional eyeball networks. Wrong way: Using a different set of transit carriers at each
