Hmm, I don't know. It occupies a strange spot in the demand curve, doesn't it? Below C1M, you use commodity hardware. Above C100M, you're forced to use distributed systems, since no single machine can possibly handle the load. But if you're in a startup, like many HN users, you have to fulfill Investor Storytime. In this consensual hallucination, everyone pretends the company can hockey stick at any minute. In this environment, you can't have hard limits. If the investors ask "What if traffic goes up by 1,000x?" you can't say "We die", because then you become unemployed. So this thing is purely for companies with predictable loads... stable, established companies. Enterprises! Resume poison! Nobody in this economy would be so foolish as to admit experience with enterprise software, IBM z series(!), lest ye be cursed forevermore with its taint. Throw salt over your left shoulder, spit three times... A good HN user only uses cloud autoscaling, serverless, Lambda, anything to stay out of bank IT shops, where you're paid $70k a year and get outsourced at the drop of a hat. I now understand why OP died with a mere 22 votes. Better I should forget the acronym "SSI" entirely, lest it contaminate me, become fallen... I clear my mind, think of web scale, BigTable...
