---

✅ With this updated plan, all 3 VMs stay online for 12 months, OS disks assigned properly (2 free SSDs + 1 minimal HDD), and CDN offloading keeps egress charges near zero.

Using Cloudflare Tunnel we can avoid $45 per year charged due to Public IP.

(When Site is in ready state).

Further to avoid $2/mo //$24/year, choose anyone VM from B2pts-v2(powr-vm) {ARM based} or B1s (sprt-vm) {intel x64 based} according to your need.
