Hi Isaiah > Are there guidelines with minimum server specification for setting up a > local instance of dhis2. Not really. The actual requirements are very much dependent on the context of use - number of users, number of orgunits, tracker vs aggregate etc. If you are talking about something that will just run on your laptop, then I think the very minimum you might get away with is about 2G RAM but that would only do for a very small database.

Re: [Dhis2-users] server specification
My goodness this seems to have pressed so many buttons for the cloud fetshists. Would you ever just answer the question. There can be any number of good reasons why someone might be buying hardware. Nami, if you are buying/renting a virtual server I'd try out pretty small and see what you can get away with. So something like 4G RAM and 2 cpus might well handle the load. (Having 50 users is one thing but its also pretty variable depending on what those users are actually doing). If you find yourself struggling you are going to need to increase but that is generally painless enough. Thats a real benefit of cloud provisioning. If you are investing in physical hardware then do be sure to think a lot about some of Jason's points. You need to think beyond a single machine and think about the environment, redundancy, off site backups etc. All of which are perfectly possible to think about and manage Generally you will take the opposite approach from above and budget for more than you need to take into account growth etc, and just that you really don't want to be left short on what might be a long and arduous procurement process. A possible sensible approach many organisations take is to invest big in hardware and then virtualize within it. After all that, a thumbsuck for a 50 user system . Quad core cpu with 32G RAM and 1TB of storage of which maybe 100G ssd. Backup server with a big disk (and not much else). Depending a lot really on where you are, maybe a tape drive for archive.

To my knowledge. the vast majority of production DHIS2 instances are using some type of virtual hosting arrangement, but there are others who insist on purchasing hardware.
