Icelandic cloud provider GreenQloud, which boasts operations running on renewable energy, has released its QStack hybrid cloud software built on Apache CloudStack.

GreenQloud operates out of the Advania and Verne Global data centers in Iceland and Digital Fortress in the US. It was founded in 2010 and has been helped to grow by funding from the Icelandic Centre for Research.

The company said the software will enable enterprises and organizations to build private clouds as well as scale and migrate workloads to GreenQloud’s renewable energy-powered public cloud.

The company said it is augmenting its existing service offerings in the public cloud with hybrid and private cloud solutions that focus on its easy-to-implement and easy-to-use software.

QStack will enable users to utilize GreenQloud’s public cloud software on their private infrastructure and will allow for burstability into GreenQloud’s renewable energy-powered public cloud.

The hybrid solution aims to allow for a more conservative investment into IT infrastructure, solve the problem of scalability in the face of changing demands and encourage the adoption of sustainable cloud practices.

It said the software is built on Apache CloudStack with open source components like the KVM hypervisor and (optionally) third-party commercially supported software such as VMWare and Scality object storage.

The company said QStack features a customizable dashboard with built-in white labelling and theme support, industry standard API support (EC2, S3 and Apache CloudStack 4X compatible), built in usage metering  including reporting and billing.

It said QStack’s security features include team and project support, single sign on authentication, user controlled load balancers and firewalls.
