Google Offers Cheap Cloud Computing For Low-Priority Tasks 59

Posted by Soulskill from the guaranteed-7-7s-of-uptime dept.
jfruh writes: Much of the history of computing products and services involves getting people desperate for better performance and faster results to pay a premium to get what they want. But Google has a new beta service that's going in the other direction — offering cheap cloud computing services for customers who don't mind waiting. Jobs like data analytics, genomics, and simulation and modeling can require lots of computational power, but they can run periodically, can be interrupted, and can even keep going if one or more nodes they're using goes offline.

    Preemptible VMs are the same as regular instances except for one key difference - they may be shut down at any time.

      Yup, it's their version. Forbes compares them. [forbes.com] The fixed price is nice on the Google side, but there's no 2-minute warning before termination on Google like you get on AWS, and AWS launched a new Spot Fleet [amazon.com] product the same day Google announced.

      Either way, you need to be doing the kind of work where you can lose VMs on short notice and keep going, but it's a very nice discount if you can.

        They do give you 30 seconds of warning: https://cloud.google.com/compu... [google.com]

        Compute Engine performs the following steps to preempt an instance:

        Compute Engine sends a preemption notice to the instance in the form of an ACPI G2 Soft Off signal.
        If the instance does not stop after 30 seconds, Compute Engine sends an ACPI G3 Mechanical Off signal to the operating system.
        Compute Engine transitions the instance to a TERMINATED state.

        So if you're able to persist your state in less than 30 seconds, just watch for SIGTERM and you should be golden. Otherwise, checkpoint frequently.

        • It goes without saying (although I am reminding people) that frequent checkpointing should be done as standard operating procedure.

        The only problem is availability... Short of maybe database and legacy software... You shouldn't be writing distributed system that can't handle individual node failure..
        So the only thing holding this back is the fact that they don't promise availability and that they can take down all your nodes at once.

        I would argument one ought to run a percentage of ones servers as spot nodes... or preeamable VMs.

    In a way the cloud was big way back when. I remember in the late 70's my high school had a matrix dumb terminal tied to a couple college servers. It seems we are going back to that way of thinking. Use minimal hardware and let the power of the processing be handled elsewhere.

      It is not about the processing power, it is about the control. However controls the data owns the data, regardless of law.

      Cloud computing is far more than just that. What happens when the school wanted more pupils than they had computer power for? Could they magically spin up a new computer out of thin air for the new users to use? Cloud computing is the combination of having your own mainframes/servers, and being able to add to their number/reduce them as close to instantly as physically possible. This lets small players have the same computing power at their fingertips as large companies, which is not the case with the s

      We'll need more information to determine how long you have been programming, since you could have started moments before your post based on that criteria. VIM is still one of the best IDEs available (people mistakenly refer to it as an editor; that's like calling a car a windsheild; yes VIM has an editor, but it is much more than that.)

  • Small comment on that last point:

    Any large-scale computing implementation must be able to deal with nodes going offline. For example, if typically you have one hour of downtime per machine per year, and are running a process on 10,000 nodes, then at any given time you have about a 64% chance of having at least one node down. If you have to restart the process on all 10,000 nodes, that's going to be a huge amount of wasted computing power.

    Back in the day, you could set your priority on a Cray XMP to 0.01 so that you got 100x the minutes you were allocated but that your code only ran when the machine was otherwise idle.

    • Indeed, load balancing and shifting is not new. It is, however, important and Google needs it to get maximum profitability out of their servers. To do so people need to know that it exists.

      Google did not claim there had not been other systems with similar load balancing. They simply explained what it was and how to use it. You know, the data you need to know if it is applicable to you.

    This is a really good idea from a resource utilization standpoint. Reminds me a lot of the power grid - you have to have enough hardware to handle the peak load, but idle capacity just costs you money.

  • Amazon's spot instances are better in every way. Not only are they usually cheaper than Google's fixed prices, but you can run them for way more than 24 hours. I have a Spot Instance running for 4 months at about 1/25th the price of the on-demand instance, and way cheaper than Google's preemptible instance too.

    The limit of 24 hours seems to be designed to prevent people who want to run long-running tasks from using up the spare compute power on something like a VPN. That's fine with me; Amazon can have my b
