The physical boundary
VPS shares a host. Dedicated gives you all CPU, RAM and disk. Noisy neighbors, custom RAID or certain Windows licensing often push you to dedicated.
Upgrade signals
- Sustained 80%+ CPU/RAM
- Disk IO wait spikes
- Compliance needing physical isolation
- Try VPS/cloud resize first
- If still short, plan dedicated
- Or hybrid: app on VPS/cloud, DB on dedicated
Because KuzeyDC runs dedicated and cloud/VPS in one facility, upgrades avoid latency penalties.
