Congratulations and many thanks, it’s great to see this expansion in the range of hosting options available to national governments, NGOs, etc.
I suspect, however, that you may want to reconsider the word “sovereign” in the title of your offering. It looks like you’re using AWS servers, which do not meet the definition of digital sovereignty on two counts:
- For most countries, national AWS hosting options won’t be available - they would have their servers hosted on regional AWS servers (ie the data will physically sit in another country).
- Because Amazon is a US-based company, it’s subject to US laws, and this overrides national laws - for example, the US government could order the servers switched off as part of a package of sanctions, or could even order Amazon to provide it with access to those servers.
Please forgive me if I’ve misunderstood your setup (eg if you’re in fact planning on hosting servers in each country?), but if not, then it might be prudent to remove the word “sovereign” from your offering.
Having said all of this, it’s important to note that all other DHIS2 cloud-hosting services experience the same “sovereignty” limitations, so this does not in any way detract from your offering. On the contrary, it’s great to see how simple and easy-to-use your platform is, and that you’re using a modern, best-practice server management architecture. 
I wish you every success with this initiative. 
Regards, Sam.
