Eucalyptus “EucaNUC” compared to public cloud

In an earlier article (, I provided details of how to build a low-cost private cloud alternative to a “public cloud” that is small enough to sit on your desk, called EucaNUC.

Why EucaNUC? Having your own “private cloud” is complementary (think hybrid) to “public cloud“, Eucalyptus is API compatible with Amazon AWS core services (see below). For instance, you could develop on EucaNUC and move (think burst) into Amazon AWS for production. Same tools, same scripts, no changes.

Let’s compare the one-time cost of $1650 for EucaNUC to monthly public cloud usage.

$1,650 buys you a month or two on a “Public Cloud” or a lifetime of private cloud on your desk.

Cost of EucaNUC (Amazon pricing as of Aug 12, 2013):


Editor note: I know this is not a direct apples-to-apples comparison, but for simple cloud usage, it’s close enough.

If Eucalyptus VMTypes are configured similar to Amazon AWS m1.small (1 ECU, 1.7 GB Ram) you could run 18 instances on EucaNUC simultaneously.

Not only does EucaNUC look cool on your desk, it runs cool and quietly too. To expand capacity of EucaNUC, you simply add another Intel NUC node controller to the cloud.

Amazon AWS Feature Compatibility:

  • Amazon Elastic Compute (EC2)
  • Amazon Elastic Block Storage (EBS)
  • Amazon Machine Image (AMI)
  •  Amazon Simple Storage Service (S3)
  • Identity and Access Management (IAM)
  • Auto Scaling
  • Elastic Load Balancing
  • Amazon CloudWatch
  • Resource Tagging
  • Web Based User GUI

Eucalyptus is complementary to Amazon AWS, sometimes you need a “private cloud”, sometimes you need “public cloud”, sometimes “both” and how cool would it be to have a Amazon AWS API compatible private cloud that sits on your desk! EucaNUC delivers this!
