Hi Nami,
Generally, we would probably advise you not to buy hardware, unless you have very specific reasons to do so. There are many providers who can provide such services such as Linode, DigitalOcean, Amazon Web Services among many others. 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. However. it is not only the hardware which is the problem. You must have backup devices, UPS, air conditioning and of course, sufficient bandwidth to support an Internet facing server. Basically, everything you would already expect to find in a data center. So, it is not only the server, and in the end, the total cost of ownership will be likely orders of magnitudes higher, than putting your DHIS2 instance with a cloud provider.

Best regards,
Jason

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.

Sorry Paulo and Jason.

I misinterpreted your response thinking you were ignoring Nami's
question in order to ask your own. Don't mind me,
