Background
DigitalOcean is a new and upcoming cloud hosting provider, similar to Rackspace Cloud, SoftLayer, and Linode. DigitalOcean came out of the TechStars cloud incubator, mentored by Jason Seats a SliceHost cofounder.
DigitalOcean offers traditional virtual machines with full root access. What makes them stand out from the competition is all their storage is SSD backed, their community of guides and projects is arguably one of the best, and their prices are super affordable. Full discloser, Commando.io is sponsored by DigitalOcean. Anyway, let’s get right to the server setup.
The Setup
SoftLayer
- 2 CPU’s
- 1024 MB RAM
- 100 GB Disk
- 1 TB Bandwidth
- CentOS 5.3 x64
- $106.00/Mo
DigitalOcean
- 1 CPU
- 1024 MB RAM
- 30 GB SSD Disk
- 2 TB Bandwidth
- CentOS 5.3 x64
- $10.00/Mo
Unix Bench Results
We used a standard benchmarking utility called Unix Bench, which runs through a gauntlet of tests. Since it would not be equivalent to benchmark using multiple CPU’s (DigitalOcean only has a single core) we ran the benchmark using a single thread so the results are accurate.

Takeaway & Conclusion
Not only is DigitalOcean 91% less expensive than SoftLayer, it is 3.25X faster according to Unix Bench. One difference is the SoftLayer virtual machine has 2 CPU’s for better parallelization and 100GB of storage instead of DigitalOcean’s 30 GB of SSD. However, for just $80/Mo or $70 more per month you can get a server with 4 CPU’s, 8 GB of RAM, and 80 GB of SSD storage from DigitalOcean which will absolutely crush the performance of SoftLayer and is still $26/Mo cheaper.
