Facebook Engineers Crash Data Centers In Real-World Stress Test (ieee.org) 52

An anonymous reader writes: In a report via IEEE Spectrum, Facebook's VP of Engineering Jay Parikh described the company's "Project Storm" -- regular takedowns of Facebook's data center intended to stress test the company's disaster recovery efforts. The first few didn't go so well, he reports. (Perhaps doing a test during a World Cup final was not such a good idea). Months and months of planning went into the initial effort, though up until the actual moment, other Facebook leaders didn't think he'd actually take out an active data center. "In 2014, Parikh decided Project Storm was ready for a real-world test: The team would take down an actual data center during a normal working day and see if they could orchestrate the traffic shift smoothly," reports IEEE Spectrum. Parikh recalls: "I was having coffee with a colleague just before the first drill. He said, 'You're not going to go through with it; you've done all the prep work, so you're done, right?' I told him, 'There's only one way to find out'" if it works. (Parikh made the remarks at this week's @Scale conference in San Jose.) Parikh says there never seemed to be a good time to perform the live takedowns. "Something always ended up happening in the world or the company. One was during the World Cup final, another during a major product launch." The report adds, "The live takedowns continue today, with the Project Storm team members coming up with crazier and crazier ambitions for just what to take offline, Parikh says.

    This is totally worth it. What would happen if there was a REAL disaster (like a nuclear strike) and people couldn't check their facebook feed and post "thoughts and prayers" messages? Too terrible to think about.

        News DISTRIBUTION service. It's not like they provide any original content like AP, Reuters, etc.

          In that AP and Reuters are just distribution services, Facebook is arguably a larger source of original news distribution than those two.

          And kudos to their engineering team for not just paying lip service to reliability.

            AP and Reuters both have reporters in their employ. FB does not, AFAIK. I'd guess FB also technically could probably be accused of copyright violations regarding reposting AP/Reuters stories. FB nothing more than a massive "look at me" and gossip site.

            And kudos to their engineering team for not just paying lip service to reliability.

            I would agree with this. Running real world tests is the only way to be sure.

      • I'm not sure you really know what "news service" means ...
      • News Service for Morons. Kinds like G+ users.

        There you go. Fixed that for you.

      Or maybe given Facebook's system of being able to announce on your feed to your friends and family that you are in fact okay thus reducing panic situations, it's much more important than your prejudices make it out to be.

      • You are right. "Lolz guys..TOTALLY not incinerated in the nuclear strike today...", check out this cool cat video.
      • I think that what Mr. 110010001000 is pointing out is:
        People think it's easier to get an internet connection (and assume that others have an internet connection) and view/post about being ok than it is to simply pick up a phone and call your loved ones, or even stranger, leaving the house and actually checking on them.
        • In disasters where internet connections are major issues, so are typically phone calls. But this isn't the scenario I was talking about. In every disaster there are a higher portion of people not affected than are affected. Getting a message out casually on social media can help reduce the stress on the phone network which is better served for the actual emergencies going on at the time.

          • I don't think I understand. Do you mean that if a nuclear strike or earthquake hits California, and it destroys a lot, as far out as Nevada, then the folks in Utah should still be able to say "I'm ok" to the folks in New York, via facebook? Because what I got out of what 110010001000 said was that the folks in Utah should be scrambling to help those in Nevada and California, rather than browsing facebook, and cat videos. I may be reading to much into it though.
            • Yes that's exactly what I was saying, and not everyone is in position in every case to help someone. The idea that an entire city of people will suddenly flock to another to "scramble to help" is simply absurd. The world will keep turning and no one can do 100% all the time so critising people for being on facebook is not really thinking ahead.

              Now on the flip side Italy had an earthquake the other day. My sister was in Italy, I don't know where she was, just that she was travelling through. My first reactio

              • I like your reply, really I do. You have a great point, and using the real-world example from Italy helps. However I'd like to point out that...

                The idea that an entire city of people will suddenly flock to another to "scramble to help" is simply absurd.

                ...is simply absurd. Not sure where you live, but I'm very near to Mississippi (a place where we used to get multiple hurricanes every year). When Hurricane Katrina hit, it was not possible to reach anyone there without traveling to the area (southern-most parts of Louisiana to Mississippi). The only government help in place was positioned at the Walmart(s) to

      Back in the 70s (Before I was in the field professionally, but knew 'enough') I was brought by my dad to Bunker Remo, who did all the stock market data. (My dad worked on their HVAC)
      At the one site, they had TWO mainframes (yes, this was pre IBM PC era) with DRUM memory (Yes, I've seen operational drum memory!! - an I have one word of memory from the computer - discrete transistors!!!)
      Anyway, it was a cluster! One computer could take over for the other. Guy said "Oh, that's nothing, there are 2 more in Midt

    Good for him! Most DR exercises I've seen are planned weeks, if not months in advance. They are more of a scheduled fail-over to a redundant site and not an actual disaster recovery test.

    In the event of an actual disaster, there would be no recovery.

    I'm heartened to see SOMEONE does it right.

    • Most large banks I have worked with do full DR exercises, and have since the 90's at least. Smaller banks will simulate typically, but one bank I know of actually shifted mainframes to their DR warehouse and brought things up from there.

      Now with hot-hot sites, the activity is much more trivial, but it is obviously not a universal thing across all organizations.

  • Thats how you should do it. Disasters dont wait around untill your not busy doing something else, they hit when they want to. Thats why i think live testing is important to see if recovery plan works or needs iteration of improvement... Best test is usually when disaster strikes right when you have hands full of something else... No time to dig up manuals, etc...

    So Netflix has been doing this for years now... it's called the Chaos Monkey and part of their "Simian Army" that performs this kind of function but *all the time* with no schedule. This is not something FB came up with but this post seems to give them credit for this innovation. More interesting than the lack of credit to Netflix though is this adoption of a method that heavily favors a Microservice Architecture. Seeing more and more of this flexible, scalable, and highly resilient architecture and methodology being put out in industry is certainly encouraging.

      Actually, this is one of the better story summaries I've seen here.

      I knew what it was talking about (no unexplained mayfly buzzwords), I knew who the protagonists were, and I knew what was at stake. The only implied innovation was one of personal chutzpah, against the backdrop of an organization notorious for taking all things in collective stride (these being very, very short strides).

    Pity.

  • Just when you thought your privacy could be restored by the massive failure of a data center, a new center rises up from the ashes of the other to take the helm of stealing every personal detail about your life and the life of people you love.
  • It would be very useful for Facebook to stop announcing ASN 32934 for a few centuries as an experiment just to see what would happen.

    Or permanently remove authority records for facebook.com.

    You know just to see what would happen.

  • Months and months of planning went into the initial effort, ...

    Into the take down or recovery? 'Cause the former just requires pulling a cable of some sort. :-) TFS says the team would take down a site and try to migrate the traffic, but wouldn't it be better if the disaster group and the recovery group were different teams for a "real world" stress test?

  • There it's called "DiRT" (stands for "Disaster Recovery Test").

  • Reminds me of "Chaos Monkey" from the netflix simian army.

  • This reminds me of when Pee-wee Herman fell off his bike and then got up and said: "I meant to do that"

"Virtual" means never knowing where your next byte is coming from.
