In the next series of posts and videos we will take a look at the journey of one our community members. He started with a single machine running Eucalyptus 4.0, then added a few canned images. From there he started to build his own images using Packer.io from ISO and then customized these images with additional software packages. With the usage increasing of the single Cloud-in-a-Box (CiaB) machine, it was time to increase the capacity by adding more compute power or Node Controllers (NC)....

I frequently check out Dustin Kirkland’s blog to get ideas about how to secure instances running on various cloud infrastructures.  Recently, I stumbled across one of his blog entries, where he discussed a package called ‘overlayroot‘, which is part of the cloud-initramfs-tools package for Ubuntu.  The really interesting feature I liked about this package is the ability to encrypt – using dmcrypt –  the root filesystem of the instance.  What this means that if the Node Controller...

The cloud computing market includes so many players and technologies that measuring its actual size can be difficult. This year alone, there was a Skyhigh Networks report estimating that shadow IT was 10 times the size of known cloud usage. And although Google Trends has shown a leveling-off of searches for the term "cloud computing," this is likely a sign of growing familiarity with the benefits of cloud computing rather than declining interest.

So how big is cloud computing? Some...

At Eucalyptus, we’ve leveraged the existing compute infrastructure to deploy some new services. For example, ELB and our imaging service user workers that run as instances. This is useful because the cloud administrator won’t need to configure new machines to handle these tasks. The workers can be dynamically provisioned on top of existing infrastructure and that’s what cloud is all about! The management console can be deployed on top of Eucalyptus as well. In fact, using ELB and Autoscaling...

There's really no straightforward answer to "private or public cloud?," since no two organizations have the same requirements for security, control and application performance. In many instances, the best path forward is hybrid infrastructure, which provides all the benefits of cloud computing - elasticity, self-service and the like - with added mechanisms for controlling when and where workloads run.

Gartner vice president Milind Govekar recently outlined why the hybrid cloud - i.e...
