Cloud platforms are excellent for experiments and for workloads that swing wildly. Once something runs steadily around the clock, the bill often climbs past what the same capacity costs as a dedicated server. This guide covers how to tell whether you are at that point and how to move without drama.
Signs the cloud is costing you too much
- Instances run 24/7. Hourly pricing is a premium you pay for flexibility you are not using.
- Egress is a big line item. Per-GB outbound charges add up fast for media, downloads, game traffic and backups. Dedicated servers usually include unmetered ports or large allowances.
- You pay for disk performance. Provisioned IOPS and premium volumes cost extra in the cloud; local SSD or NVMe on a dedicated server is included.
- You run many small VMs. One large server with Proxmox can host them for less.
When to stay in the cloud
Keep workloads where they are if they scale to zero for long stretches, depend heavily on managed services such as serverless functions or proprietary databases, or need capacity in a region we do not cover. Many teams end up hybrid: steady base load on bare metal, burst and managed services in the cloud.
Sizing the replacement
Cloud vCPUs are usually hyper-threads, not whole cores, and they often share hardware. As a rough rule, two cloud vCPUs equal about one physical core on a dedicated server, and the dedicated core does not slow down when a neighbor gets busy.
- Pull a month of CPU, memory, disk and network graphs from your cloud console.
- Size for the 95th percentile, not the average, and add headroom.
- Add up memory across all instances you plan to consolidate, plus about 10 percent.
- Match storage type: if you pay for provisioned IOPS today, choose SSD or NVMe.
- Pick a city close to your current cloud region so latency to your users stays the same.
A low-risk migration plan
- Order the server and build it the same way. Use the same OS version and your existing configuration management or install scripts.
- Lower DNS TTLs to a few minutes a day or two before the move.
- Copy data and start replication. Database replicas, rsync for files, object storage sync for buckets.
- Test against the new server using a hosts-file entry or a staging hostname.
- Cut over during a quiet hour: stop writes, let replication catch up, switch DNS, watch logs.
- Keep the cloud copy for a week as a rollback, then shut it down.
What changes after the move
You trade some convenience for control. Snapshots become your backup routine, scaling means ordering another server rather than clicking a slider, and operating system updates are yours to schedule. In return, your bill stops changing every month and your performance stops depending on someone else’s workload.
