I&#x27;m not in the US (though I&#x27;ve looked at the HIPAA guidelines anyway in the course of my research), I&#x27;m in the UK and will only be storing UK data (at least initially, I suspect there is strong demand for the idea but I&#x27;m a) not planning on making huge amounts of money b) supporting other countries since the laws on medical data are so varied), I spoke to friends in local government who put me in touch with the people who deal with storing medical data for them, as long as I follow best practices, make sure that users are aware of the license terms of using the system and behave ethically that (appears) to be all that is required except for of course obeying the rules on DPA&#x2F;PII (Data Protection Act, Personally Identifiable Information), as I&#x27;m not a public organisation their rules don&#x27;t apply (though I&#x27;m still going to follow <i>all</i> their guidelines anyway).<p>I&#x27;m still going to speak to the company solicitor though just for belts and braces.<p>Oh and on the hosting, I won&#x27;t be using any cloud services, Physical server out of a a state of the art DC a few miles up the road that is certified to my UK Gov standards as a provider, they pretty much tick every box I&#x27;d ask for though not cheap I can get an insanely powerful machine and they have a <i>superb</i> reputation, looking at approx 75 quid ($110) per month for a dual core i3-4160&#x2F;8GB RAM w&#x2F;1TB RAID or £145 ($210) a month for a Xeon 1231 with 32GB RAM and 2TB of RAID storage (that one has dual power supply, n&#x2F;c) which if it&#x27;s <i>used</i> isn&#x27;t that expensive at all.
