Azure function using Azure Active Directory managed identity to authenticate with Azure SQLServer in Azure and working transparently locally. Using Dapper as ORM.

"Your account control strategy should rely on identity systems for controlling access rather than relying on network controls or direct use of cryptographic keys" - Microsoft Well Architected framework Security pillar

Context and steps

  1. Create Azure SQLServer and database, only allow AAD auth
  2. Set AAD admin, preferably a group account and add whoever needs admin access
  3. Set firewall rules
  4. Test connection with e.g. SSMS using AAD - universal with mfa login
  5. Create a table ('test' is used here)
  6. Create function app, http triggered VS 2022, copy code from here

{ accessTokenFactory: () => "aJwtToken" })
.build();

Serverless, FaaS

Azure Functions (release 2, beta)

PROS

  • the only "big" provider supporting node.js LTS 8 (aws and gcp still on 6.x)
  • automated deploy using git (tested w bitbucket), use different function apps per env (dev, stage, prod etc) and map against branches
  • local dev environment

CONS

  • cli deploy very unstable
  • "function host not running" errors

https via Cloudflare with github pages on custom domain with redirect to www
  1. assuming you already have your domain, will use domain.com as example and you have your github pages, will use username.github.io as example
  2. register for cloudflare account
  3. get cloudflare nameservers for your domain, e.g xxx.ns.cloudflare.com and yyy.ns.cloudflare.com
  4. update dns settings for your domain with the cloudflare nameservers and check status (might take a while)
  5. cloudflare dns settings -> add 2 A records; name: domain.com, value 192.30.252.153 and value 192.30.252.154 as per github pages instructions
  6. cloudflare dns settings -> add cname record; name www, value (is an alias of) username.github.io
  7. cloudflare page rules -> domain.com/* forwarding URL https://www.domain.com/$1 301 permanent redirect
  8. cloudflare page rules -> http://www.domain.com/* Always use https
  9. settings on your github pages repo -> custom domain 'www.domain.com'
