Azure Virtual Machines vs DigitalOcean
Azure Virtual Machines is a huge menu of Linux, Windows, Arm and GPU machines in 77 regions, with quotas, reservations and Spot. DigitalOcean Droplets are simpler Linux servers with a fixed hourly price and a monthly cap, but a new team can only run 3 at once.
The companies and products
Azure Virtual Machines
Azure Virtual Machines is Microsoft's general-purpose cloud VM service: you rent Linux or Windows machines by the minute in Azure regions worldwide.
It is a hyperscaler IaaS product, not a sandbox API. Each VM runs on Microsoft's Hyper-V hypervisor with its own kernel, root and SSH, and you pick from hundreds of sizes, including Arm, burstable and GPU families. Networking, disks, images, firewalls and any agent tooling are separate pieces you set up yourself, so it suits teams that already run on Azure and want full control.
DigitalOcean
DigitalOcean is a general-purpose cloud, and Droplets are its Linux virtual machines.
A Droplet is a Linux VM you rent by size, with root, a public IP, local SSD and a monthly transfer allowance. You pick an image, then install and run your own software on it, next to DigitalOcean products like Kubernetes, managed databases, load balancers and cloud firewalls. It is a server host, not an agent sandbox, so this page compares the two where they overlap: giving an agent its own Linux machine. DigitalOcean also sells two separate products in preview, Harness Runtime for agents and MicroVMs, which are not Droplets.
Which use cases each one fits
For each use case, Battleships prices every sandbox provider on the same workload and sorts them from the cheapest monthly bill up. “3rd cheapest of 364” means 2 of the other 363 providers run that workload, with every feature it needs, for less. “With limits” means the provider runs it but misses something, so it is listed after every full match. Open a use case for its whole ranking and what each provider misses.
| Use case and its workload | Azure Virtual Machines: price rank | DigitalOcean: price rank | bochka: price rank |
|---|---|---|---|
| Software factory 100 at once · 4 vCPU / 8 GB · 2,200 sessions of 8 h a month Both give a full Linux VM with root and Docker that you set up yourself; bochka ships agents, snapshots, HTTPS URLs and free stops on every machine. | 83rd of 367, with limits $730 a month | 134th of 367, with limits $1,187 a month | 3rd cheapest of 367 $634 a month |
| Always-on AI employees 50 machines 24/7 · 2 vCPU / 4 GB A Droplet is the simpler always-on server and Azure is cheapest only on a 3-year reservation; bochka runs it month to month with snapshots and a desktop. | 113th of 366, with limits $644 a month | 35th of 366, with limits $1,429 a month | 5th cheapest of 366 $657 a month |
| Code interpreter bursts 100 at once · 1 vCPU / 2 GB · 200,000 sessions of 1 min a month DigitalOcean bills per second with a 60 second minimum and Azure per full minute, so both suit short runs better than bochka, whose start limits make big bursts a compromise. | 114th of 345, with limits $222 a month | 63rd of 345, with limits $60 a month | 186th of 345, with limits $2,000 a month |
| Sandboxes for your users 300 at once · 2 vCPU / 4 GB · 30,000 sessions of 23 min a month A new DigitalOcean team can run 3 Droplets at once, and Azure caps vCPUs per region and family; bochka allows 100 to 2,000 sandboxes by plan. | 63rd of 361, with limits $500 a month | 54th of 361, with limits $421 a month | Cheapest of 361 $209 a month |
| RL rollouts 1,000 at once · 2 vCPU / 4 GB · 1,000,000 sessions of 3 min a month Azure Spot VMs make big RL fleets cheap if rollouts survive eviction with 30 seconds of notice; DigitalOcean sells spot only for GPU Droplets. | 19th of 360, with limits $1,039 a month | 31st of 360, with limits $1,786 a month | 34th of 360, with limits $2,000 a month |
| Agent evals 250 at once · 4 vCPU / 8 GB · 15,000 sessions of 20 min a month Azure fits eval batches well with per-minute billing and many sizes; on DigitalOcean the 3 Droplet limit of a new team gets in the way first. | 3rd cheapest of 364 $173 a month | 106th of 364, with limits $357 a month | 10th cheapest of 364 $200 a month |
| CI runners 40 at once · 8 vCPU / 16 GB · 6,000 sessions of 12 min a month | 35th cheapest of 377 $335 a month | 146th of 377, with limits $171 a month | 4th cheapest of 377 $86 a month |
| 24/7 dev boxes 1 machine 24/7 · 4 vCPU / 8 GB All three fit a 24/7 dev box: a Droplet or an Azure VM is a classic always-on server, and a bochka machine keeps its disk with snapshots every minute. | 72nd cheapest of 368 $94 a month | 39th cheapest of 368 $48 a month | 18th cheapest of 368 $26 a month |
| Computer-use agents 50 at once · 4 vCPU / 8 GB · 20,000 sessions of 15 min a month Neither Azure nor DigitalOcean has a desktop stream built in, so you install a desktop and VNC yourself; bochka streams a 60fps desktop with Chromium. | 100th of 369, with limits $192 a month | 117th of 369, with limits $263 a month | 6th cheapest of 369 $200 a month |

Performance
There is no comparable measurement for Azure Virtual Machines or DigitalOcean: neither was in the public StarSling benchmark run. bochka did 26.69 Node.js build-and-test runs per second at 4 vCPU / 8 GB in that run of 2026-09-29. On both clouds, speed depends on the plan: Azure has many CPU families and burstable sizes, and DigitalOcean's Basic plans share hyper-threads with other Droplets.
Node.js build-and-test loop at 4 vCPU / 8 GB, higher is better. Measured with the open hpc-sandbox-benchmarks suite. Azure Virtual Machines and DigitalOcean have no published run in this suite yet, so there is no like-for-like number to compare.
Pricing in five scenarios
Each bill is priced from the providers' public price lists by the open Battleships engine, with the cheapest plan that runs the scenario.
| Scenario | Azure Virtual Machines, a month | DigitalOcean, a month | bochka, a month |
|---|---|---|---|
| One coding agent, workdays 4 vCPU / 8 GB, 50 GB disk, 8 hours a day, 22 days a month, files kept between days | $26 · Pay-as-you-go subscription (no plan fee) | $13 · Pay as you go | $20 · $20/mo |
| One agent that never stops 4 vCPU / 8 GB, 50 GB disk, running 24/7 all month | $48 · Pay-as-you-go subscription (no plan fee) · with limits | $48 · Pay as you go | $26 · $20/mo |
| 50 agents in parallel 50 machines of 4 vCPU / 8 GB at once, 8-hour sessions, 1,100 sessions a month, Docker inside | $1,168 · Pay-as-you-go subscription (no plan fee) | $629 · Pay as you go · with limits | $317 · $20/mo × 3 seats |
| Sandboxes for your users 2 vCPU / 4 GB, 30,000 sessions of 10 minutes a month, up to 300 at once | $225 · Pay-as-you-go subscription (no plan fee) | $179 · Pay as you go · with limits | $200 · $100/mo × 2 seats |
| 1,000 short jobs at once 2 vCPU / 4 GB, 1,000 at once, 3 minutes each, 200,000 jobs a month | $483 · Pay-as-you-go subscription (no plan fee) · with limits | $357 · Pay as you go · with limits | $2,000 · $2000/mo · with limits |
Azure Virtual Machines: Azure bills each VM per full minute while it runs, with no plan fee; disks, public IPv4 and egress are billed on top, and disks keep billing while the VM is deallocated. The cheapest machine that never stops needs a 3-year reservation, billed whether it runs or not.
DigitalOcean: Each Droplet size has a fixed hourly price, billed per second with a 60 second minimum and capped at 672 hours a month. Billing runs from create to destroy, including while powered off, and snapshots and backups cost extra.
DigitalOcean: You pick a monthly plan from $20, and all of it becomes usage credit spent per second on running sandboxes. A stopped sandbox costs nothing and keeps its disk.
Limits in those scenarios
A new DigitalOcean team is on Tier 1: 3 Droplets at once, Basic shared plans only, so 50 agents in parallel and sandboxes for your users do not fit until you reach a higher tier. Azure fits both, within vCPU quotas per region and per family that start low and rise by request. Azure's $48 a month for one agent that never stops needs a 3-year commitment, while DigitalOcean's $48 is month to month. For 1,000 short jobs at once nothing fits: Azure's burstable VMs throttle above 30% of each vCPU, DigitalOcean caps at 3 Droplets, and bochka queues starts above its per-minute and per-day limits.
| Scenario | Azure Virtual Machines | DigitalOcean | bochka |
|---|---|---|---|
| One coding agent, workdays | None that bite | None that bite | None that bite |
| One agent that never stops |
| None that bite | None that bite |
| 50 agents in parallel | None that bite |
| None that bite |
| Sandboxes for your users | None that bite |

Which one should you use?
Use Azure Virtual Machines when
you need Windows, Arm, hibernation, Spot pricing or a region in almost any country, or your company already runs on Azure.
- Windows, Arm and many sizes. Useful if agents need Windows or Arm machines, or a very specific size: Azure rents all of these, DigitalOcean is Linux on x86.
- Regions almost everywhere. Useful if data must stay in a given country: Azure lists 77 regions worldwide against DigitalOcean's 13.
- Hibernation, Spot and reservations. Useful if a VM must resume with its memory, or big batches can survive eviction or commit for years to pay less.
Use DigitalOcean when
you want simple Linux servers with one predictable price, free firewalls and GPUs, and you only need a few machines at first.
- One simple price per Droplet. Useful if you want a bill you can predict: a fixed hourly price, billed per second and capped at 672 hours a month.
- Free firewalls and a small cloud around it. Useful if a server must sit next to managed databases and Kubernetes, behind free firewalls with outbound rules.
- Nvidia and AMD GPUs. Useful if agents train or serve models: DigitalOcean rents Nvidia and AMD GPU Droplets, including AMD MI300X and newer cards.
Where bochka fits
Azure and DigitalOcean both rent plain servers you build on. If what you are really running is agents, bochka gives each one a full VM that already has Docker, /dev/kvm, a desktop, HTTPS URLs, forks and coding agents you drive by API. It is a sandbox product, not a cloud, so GPUs, Windows and regions outside the EU stay with Azure or DigitalOcean.
Idle agents stop billing, files stay
A powered-off Droplet bills in full, and a deallocated Azure VM still bills its disks and counts against your vCPU quota. bochka saves the disk every minute and on stop, and a stopped sandbox costs nothing.
Fork a running machine in one call
On Azure a copy means stopping the VM, capturing an image and booting new VMs cold. On DigitalOcean you snapshot, then create Droplets one by one, and a new team can only run 3.
Agents, desktop and HTTPS built in
On both clouds you install the agents, a desktop and VNC, then run TLS or a load balancer for every preview link, and keys land inside the machine. bochka ships these with a credentials proxy that keeps keys out.
Use bochka when the machines are for agents: full VMs with Docker and /dev/kvm, forks of running sandboxes, snapshots every minute, free stops, a desktop, HTTPS URLs and coding agents you drive by API. Compare it one to one: bochka vs Azure Virtual Machines and bochka vs DigitalOcean.
Questions people ask
Is Azure cheaper than DigitalOcean?
Usually not in our scenarios. One coding agent on workdays is $13 a month on DigitalOcean against $26 on Azure, and one agent that never stops is $48 on both, but Azure needs a 3-year commitment for that price. bochka comes to $20 and $26 for the same two.
Which can run 50 agents at once?
Azure fits 50 agents in parallel at $1,168 a month, within your vCPU quota. DigitalOcean would cost $629 but a new team can only run 3 Droplets, so you need a higher tier first. bochka fits it at $317 a month.
Which is faster?
Neither Azure nor DigitalOcean has a comparable measurement in the benchmark we use. bochka did 26.69 Node.js build-and-test runs per second at 4 vCPU / 8 GB. On both clouds the speed depends on the CPU family or plan you pick.
Can Azure VMs and Droplets run Docker and nested VMs?
Both run Docker with root. Azure documents nested virtualization on Intel and AMD D and F sizes, not on Arm or B-series; DigitalOcean only mentions nested VMs in its live migration docs. bochka documents Docker, systemd and /dev/kvm on every machine.
Do I pay for a stopped machine?
On DigitalOcean, yes: a powered-off Droplet is billed in full until you destroy it. On Azure, a deallocated VM stops compute billing but its disks and static IPs keep billing. A stopped bochka sandbox costs nothing and keeps its disk.
Which has Windows, GPUs and more regions?
Azure has Windows, Arm and Nvidia GPUs in 77 regions. DigitalOcean is Linux only, with Nvidia and AMD GPU Droplets in 13 regions. bochka runs Linux only in the EU, with no GPUs.
