There is always polarizing discourse in the cloud vs bare-metal server debate. Sometimes, bandwidth alone costs more than an entire fleet of servers. Is the price for cloud’s flexibility worth it? If you run high-traffic websites or big data applications, here’s how to choose a side:
What’s the Difference Between Cloud and Bare Metal Servers?
Cloud servers are virtual machines running on shared hardware. Going with cloud servers means renting physical hardware with other users. You only pay for what you use. A bare-metal server is the entire physical machine. Your team runs it solo. Here’s a quick breakdown:
| Cloud server | Bare metal server | |
| Tenancy | Shared hardware | Single tenant |
| Performance | Can vary with neighbors | Consistent |
| Scaling | Minutes | Hours |
| Billing | Hourly, plus bandwidth | Monthly, bandwidth is often included |
| Best for | Spiky or short-lived workloads | Steady, heavy workloads |
Why Bare Metal Wins for Demanding Workloads
The table above shows the trade-off on paper. In practice, the teams making the switch to bare-metal from cloud points to three reasons:
Performance Doesn’t Depend On Neighbors
Cloud servers are shared. Performance throttles when neighbors get busy. Bare-metal servers give you sole access to the CPU, RAM, and disk. If you’re running 55 CPU-heavy game bots, you want consistent uptime, something bare metal servers are known for.
More Work From Fewer Machines
Stack Overflow handles nearly 2 billion monthly requests on just nine web servers. The best part is they’re only running at 5-10% capacity. But it’s not like their team never considered running cloud servers. They just said it “was never worth it.”
Full Control Over Hardware and Isolation
With bare metal, you choose the exact CPU, memory, NVMe drives, and network ports, and you can tune the operating system down to the kernel. That matters when a database needs fast local disks or a game server needs high clock speeds.
Saber Interactive, the studio behind Warhammer 40,000: Space Marine 2, fits about 100 game sessions on each bare metal machine. That would’ve cost a fortune on cloud servers.
What Each Option Really Costs to Run
If you need servers for workloads that run 24/7, cloud billing will run up costs. Imagine paying $2,000 per month for Google Cloud. Now imagine paying only $150 for a bare metal server from Hype Proxies.
According to AccelByte reports, studios are already saving up to 40% on compute costs by switching. Take this with a grain of salt. Let’s say you run a small team of five with no sysadmin experience. Cloud servers would be the best choice in this case.
There’s also an argument for hardware issues. But you don’t have to buy and rack servers. Bare metal server plans exist. You rent a dedicated physical server on a monthly basis. The provider handles the hardware, power, and part swaps in its data center.
When are Cloud Servers the Better Choice?
Bare metal servers aren’t the be-all and end-all for all compute needs. Cloud servers are a good fit for early-stage products, especially when demand is still unknown. It’s also a good choice for teams with short-lived, spiky workloads and teams leaning on managed services.
An app server could just be as easy on bare metal. However, high-availability database failover can be easier on AWS. There is always room for the middle ground. A Barclays survey found that 86% of CIOs plan to move workloads off the cloud, but IDC puts full exits at just 8-9%.
Most teams go hybrid. Saber, for example, keeps its baseline on bare metal and turns to the cloud for launch spikes. What’s important is an understanding of your needs.
Key Takeaways
Cloud keeps you flexible. Bare metal offers consistent performance at more predictable costs. The best option for your team depends on your workload, how much data it sends out, and how much your team wants to manage. To recap, here’s a quick checklist to help you decide:
- Pick bare metal for steady, heavy workloads.
- Watch your bandwidth. Bare metal wins for workloads that send a ton of data out.
- Keep the cloud for unpredictable demand, scaling in minutes, and managed databases.
- Bare metal service plans provide the hardware. Your team manages remotely.
- Hybrid is the norm. Most run their baseline on bare metal and use the cloud for spikes.
