Yes — you keep ownership of your server and pay the hosting provider directly. I just manage it. This keeps things simple: you're never locked in, and your infrastructure stays yours.
Any provider that gives you SSH access — DigitalOcean, Vultr, Hetzner, Linode, AWS EC2, GCP Compute, and others. I can also recommend the best option for your use case and budget.
Via SSH with a dedicated key. You grant access and can revoke it at any time. I document every change made to your server so you always have full visibility.
Starter plan: best effort within 12 hours. Professional: within 4 hours. Custom plans can include an SLA with defined response times. I'm in UTC+7 (Vietnam) but actively monitor alerts.
Yes, month-to-month with no lock-in. Cancel before your next billing cycle and I'll provide a full handoff document so you or another engineer can take over smoothly.
Tell me about your setup. I'll reply within 24 hours with a free audit and proposal.
