Cloud Architecture Overview

[michaelbontyes]

Assuming:

• CD-CI coming from Github Actions (configurations, binaries, Ozone execution)
• Database using MariaDB from Azure OR Docker images depending on costs/added value
• Using K3s or K8s if avoiding using a full VM is possible
• Nightly backups of patient data and files
• Uptime and performance monitoring
• Enabling HTTPS

Thanks @michaelbontyes for starting this. My Suggestion will begin from front to back
Frontend

1. Setup Azure Application Gateway as a single entry point for the entire stack .

• Involves configuring TLS termination with a domain of choice e.g (https://uvl-emr.org )
• Uploading certificates for the domain to Key vault. from a 3rd party vendor of choice (i'd recommend namecheap), because it's simple to use / setup and cheap
• Enabling cross-communication between Keyvault and Gateway

2. Create github actions / azure pipelines manifests for CI / CD into test / prod servers
3. Add / modify existing docker configuration for uvl-emr to suit the azure Infra
4. Setup Container registry with to pick up latest images after azure-pipelines CI/CD builds
5. Setup Azure Kubernetes Service (AKS) to run / manage all the containerised services in uvl-emr
6. Create K8s manifest describing deployment and ingress structure

Thank you very much @tendomart. Can you also share an estimate of the monthly cost to run such an infrastructure? Also, which part would you feel confortable to take care of if we move forward?

[tendomart]

Thanks alot @michaelbontyes This is an approximate breakdown of total costs based on Azure official documentation
Using the Azure pricing Calculator

1. Azure application gateway $0.0098 per capacity unit-hour (https://azure.microsoft.com/en-us/pricing/details/application-gateway/#pricing)

2. AKS cluster a basic plan goes for $85.41 per month (compared to a VM which goes for around $137.24 per month)

3. Storage accounts, for storing secrets $20.80 per month

4. Mysql Database $124.83 USD / month

5. Postgres $129.94 / month

6. Container Registry $5.00 / month

7. Key Vault $0.00 / month
   

I'd be comfortable to handle the AKS cluster if we moved on, though I can handle any part of the Infra implementation

Therefore the Approximate Monthly cost for the entire Infrastructure is approximately $368.17

Thank you @tendomart, today a Standard B2s VM cost < $50$ per month.

Ooh ok then we can use the cheaper option, those where just approximate estimates for running that kind of infra. @michaelbontyes above. Oh yea actually seen the B2s 2 Core costs $36.21 . Anyways with all that, it's your final decision then we can see what to implement

One more thing, since Mysql and Postgres are implemented as volumes in the current UVI-EMR there may not be need to destructure and rather go with volumes instead.
