I don't see how this addresses the reliability claim. There's a big difference between explaining that the data is stored in a Google cloud with certified 11-nines reliability, versus stored on a N number of machines in multiple clouds with unknown specs.
How do I communicate the reliability of a distributed cloud that is essentially a collection of random servers? Is there a way that each of these server's reliability is accounted for by the high-level service?
- capableweb 6y agoYou'd say something like "This content is hosted by 100 providers, with each having individual average uptime of 99.9%"
- SavantIdiot 6y agoI see. But how do I verify that 99.9%? Aren't the distributed services anonymous?
- wmf 6y agoIf you're willing to assume that each invididual server has some level of reliability (e.g. "one nine") and you assume failures are uncorrelated you can build a more reliable system using erasure coding and reason mathematically about the resulting reliability. http://www.suaybarslan.com/Reliability_Systems_14.pdf http://www.suaybarslan.com/Reliability_Systems_14.pdf
