I'm sorry I'm not aware of the person, but would be interested in reading/seeing it. A quick google search yielded https://blog.pivotal.io/pivotal-perspectives/features/revisi... - Is this the one you referred? Btw - the list is not an invention worth copying. All items in that are not novel or unique, they are general practices that every good engineer would have their own version of. I'd like to see the talk and t…

HN discussionPersistent volumes are on the horizon[1], now that Diego has landed. But you'd be surprised how many apps can be ported to some semblance of cloud nativeness. Most of the stuff that Absolutely Must Be Stateful can usually adapted to something else. Sticky sessions go to Redis or Memcache, local files can often be relocated into a shared filesystem/blobstore like Riak CS etc. The big thing about PaaSes is not that th…

HN discussionI'm not sure how much I can help because I didn't setup the RMQ cluster so I don't know the configuration details but I know it is fairly powerful (its also partly why I can't entirely be critical of Auth0 because ZMQ is probably far less expensive infrastructure wise). I do know we use multiple queues and even exchanges (and I did not know about the one core to queue). A simple googling shows though folks have achi…

HN discussionCF user here. While I agree tag support would be cool, complaining about CF buildpack incompatibility is a bit disingenuous, no? I mean, you generally can use a Heroku build pack on CF, but if you have unique requirements, that's why there are CF-only buildpacks. The general reason is that some CF deploys don't have internet access and therefore need a completely offline cache of the binaries. Secondly, > they're mi…

HN discussionLattice[1] "cheats" by turning the bin packing problem into an auction. Execution agents perform a simple local calculation and send in their bids. Then jobs are placed according to those bids. This is because while you can try to produce an optimal distribution, it's a fool's errand in a distributed system. A perfect solver, given imperfect data, produces nonsense. GIGO, as they used to say. Amit Gupta wrote some n…

The workers are run using Houdini, which is a container management daemon that, er doesn't use containers: https://github.com/vito/houdini There's a blog post by someone else at Pivotal, although the details are probably a bit out of date by now: https://blog.pivotal.io/l…

HN discussion> And we'd love to have build in support (or at least a common standard or best practices) for orchestration. Look into BOSH[0][1]. It's a IaaS orchestrator that works for multiple cloud backends -- AWS, openstack, warden and vsphere out of the box. I use it in my day job. It's already been applied to working with Docker containers.[2] [0] https://github.com/cloudfoundry/bosh [1] http://docs.cloudfoundry.org/bosh/ […

HN discussionFeedback? How about just not making wild claims about byzantine fantasy designs that you never tested under any kind of load. There has been a lot of research in messaging architectures, some of the best message brokers are free. As it happens, none of them have any resemblance to your proposed design. RabbitMQ has been benchmarked[1] to 1 million messages/sec on 30 servers and works very well for many people. Why n…

HN discussionOh, we're full of beans. And teaching client developers how we work is literally what Pivotal Labs aims to do. It's probably the first place I've worked that has a high rate of reverse-churn: people leaving to work at startups for the glamour or equity, then deciding they miss Labs and coming back. As for Diego, start with Onsi Fakhouri's keynote at the Cloud Foundry Summit this year[1], then read Amit Gupta's blog…

HN discussionThis is awesome. What I also found really cool is that this inadvertently lets you "hear the sound" of chrome/firefox throttling the `setTimeout` calls when the tab is inactive [1]. Run one of the sorting algorithms in chrome or firefox and then switch to a new tab. You'll notice it slows down. Switch back and forth between the tabs and it's almost like you are conducting of the algorithm :) [1] http://blog.pivotal.…
