The leading provider of green cloud solutions brings users flexibility, customization, and productivity with Apache CloudStack

Founded in 2010, GreenQloud began their journey with the founders of by building a prototype platform for a public cloud. GreenQloud chose to build their platform on top of CloudStack because they found many benefits from a fully open source stack to which they could also contribute. GreenQloud was one of the earliest contributors, and is responsible for CloudStack's Amazon EC2™ compatibility.

Today, GreenQloud offers a full cloud infrastructure software stack for private, public and hybrid IaaS compute and storage all the while leading the path to green IT and sustainability. GreenQloud is a cloud solutions company offering standalone private cloud, hybrid cloud and Truly Green™ public cloud computing virtual servers and data storage (IaaS) powered by renewable energy. GreenQloud's cloud services, feature an easy-to-use, self-service web console and advanced, compatible API controls for full automation of IT services.

With the addition of its newest product, QStack, the company now offers cloud solutions for the full market, accelerating the market adoption of cleaner cloud technology, by addressing the needs and concerns of companies who have not yet adopted public cloud computing due to regulatory compliance or investment commitments.

The global provider of swiss-based cloud services brings users automation, platform, and much needed services by integrating with Apache CloudStack

Exoscale is a global provider of swiss-based cloud services. Exoscale offers local or international companies real technological and financial benefits while preserving top-level customer relationship. Its service catalog proposes IaaS products from compute to storage. Exoscale combines cloud computing advantages with the know-how and experience of Veltigroup, a major and local ICT player in Switzerland. This combination between Cloud agility and proximity of a trusted service provider makes Exoscale unique on the market. Today, two datacenters physically hosts Exoscale's products. The datacenters are located in the Geneva area and separated by 10km. Due to the intuitive web based management console, provisioning of cloud servers is only a few clicks away. There is one console for all DC zones and it allows the user to access and deploy their servers from any DC zone available in Exoscale. Exoscale's services are strictly located in Switzerland and operated solely from there.

The Challenge: Offering Turn-Key IaaS Cloud Services with a Simple Cloud Interface for Developers

As the leading Swiss cloud provider, Exoscale decided to expand its services using CloudStack by creating their own UI and integrating it with a ticketing, monitoring and billing system that they developed. Exoscale required an IaaS cloud computing platform with a rich API to allow for easy integration of software to automate the management of their cloud. The UI as mentioned is custom made, built with angular.js and bootstrap and aimed for developers. It allowed Exoscale to tighten the access to the various CloudStack functionalities and integrate with their ticketing and billing system. As a result, there was no need to log into multiple systems for billing or support. Developers are directed to a simple one-step instance creation form with a straightforward way of adding a new instance. They can get a direct high-level view of instances, credits, on-going tickets and instances are displayed directly on the console dashboard for a quick and easy access to actions.

Solution: Delivering IaaS Cloud Services through an Apache CloudStack Powered Cloud

With Apache CloudStack as the base orchestrator, Exoscale is able to integrate an advanced monitoring infrastructure. CloudStack logs from the management server and all the hypervisors are sent to a redis based publish-subscribe queue and fed into an elasticsearch cluster with Kibana serving as the UI frontend to mine the logs. This gives Exoscale engineers a clean web interface to all events in their cloud and easy access to logs. In addition they used JMX metrics for java processes on the entire infrastructure, coupled with the graphite monitoring system. CloudStack's maturity, ease of implementation, open APIs and ability to seamlessly integrate with existing systems allowed Exoscale to deliver value-added services to their users giving them control and flexibility that they needed.

The Benefit: Ease of Implementation, Flexibility and Maturity

"CloudStack maturity and ease of use allowed us to focus on the ecosystem around it. As an open source group, we easily integrated software like logstash, kibana, puppet to automate the management of our cloud, this saved us a lot of time and allowed us to focus on the value add that we want to bring to our users: automation, platform, services on top of the core IaaS functionality," says Antoine Coetsier, Director Open Cloud, Exoscale. The open source nature of Apache CloudStack also means that a company like Exoscale can invest development time to enhance the platform with the features that it needs. The open source group set a great example by investing their time to integrate software with CloudStack enabling much-needed services for their users.

Technical Situation

Exoscale's cloud consists of two data centers in Geneva and Vernier, with hardware hosted by Equinix. They run Apache CloudStack 4.0.2 and use KVM hypervisors on Ubuntu based servers. One customization that was performed is that they patched CloudStack to output logs using logstash and use Kibana for visualization. Exoscale offers Debian 7.2, CentOS 6.5 and Ubuntu 12.04/13.10 64 bit templates with instance types from 512MB with 1 core to 32 GB with 8 cores. Fully licensed Windows instances are also available. All their nodes -management server and hypervisors- are setup with a puppet infrastructure. The development and operations team is relatively small for such an offering but they are backed by the Veltigroup a leading IT provider in Switzerland, which gives them a 20 person team for support. The developers are seasoned IT infrastructure enthusiasts who participate in the DevOps, openBSD, Clojure and Pallet community. The CTO, Pierre-Yves Ritschard, formerly with, recently participated in DevOps Days Paris and has contributed a Clojure client to CloudStack: clostack. Exoscale is embracing open source, not only by using it, but also by contributing to the various communities that make up the foundation of Cloud services.

The world’s leading in-car navigation provider accelerates development cycles, increases business agility and simplifies IT with Apache CloudStack.

“CloudStack adds tremendous business value because it means we can do things faster and be more flexible. If developers have a great idea that they want to test, we can more quickly give them the environments they need, including all the required interdependencies, which can be quite complex. Previously, that might have taken months; now we can deploy entire platforms in a few days.”

ISWest is a regional ISP based out of Agoura Hills, CA (approximately 30 miles north of Los Angeles). Started originally as a dial-up ISP, ISWest moved into the standard suite of ISP services including various forms of connectivity (DSL, T1, DS3, OC-x, Ethernet, etc) as well as ancillary services such as shared web and email hosting. Early growth was accomplished with a focus on small and medium sized businesses in the southern California area through strategic partnerships with outsourced IT organizations and customer referrals.

Business situation: To Stay Competitive by Offering an IaaS Cloud Service

With the benefit of owning and operating their own datacenters ISWest had a considerable amount of experience with the underlying infrastructure such as HVAC, UPS, Generators, structured cabling and other physical aspects related to datacenters.  The ISP side of the business gave ISWest experience with designing and implementing highly redundant, high performance networks, as well as the servers associated with various essential internet services such as DNS, email, and hosting.  Offering an IaaS cloud service was the next logical business step to stay competitive.

The business goal was to target existing clients either through the existing partner network of outsourced IT consultants or direct contact to prospects (typically colocation customers with old hardware).  The requirement for these customers was different than “traditional” cloud which was largely based around public-facing e-commerce or other consumer driven websites.  In contrast most customers were looking for a way to re-create network environments they were currently using which were primarily private (NAT) with only a limited number of public IP addresses used.  At the time this type of configuration was either not possible with the popular cloud providers (AWS, Rackspace, GoGrid, etc), or was exceedingly complex to configure.

Given the predictable usage of the target customer, a system that provided hourly billing data was not required, but it would be good to have available should it be required in the future.  An integrated billing system was also not required, as long as the usage data could be exported in a standard and structured format such as XML, JSON, or CSV.

Technical situation

The ultimate goal was to provide each client with their own private network, or in some cases multiple private networks, VPN access to those networks, and use VLANs to segregate customer networks from each other. ISWest evaluated a range different IaaS CMPs including Eucalyptus, Enomaly, and OpenNebula. At the time OpenStack was in its infancy and there were concerns as to its stability and/or production readiness, what direction(s) the project was moving in, and what type of support would be available if commercial support was needed.

PCextreme Achieves Business Agility with Apache CloudStack

PCextreme is one of the leading Internet Service Providers in Netherlands. The company offers a wide range of ready-to-use services including web hosting, colocation, dedicated servers, domain names and managed services. As a pioneer in the affordable hosting market, PCextreme operates with a level of scale and efficiency that allows them to combine reliability with competitive prices. What started out as a hobby for Wido den Hollander, CTO of PCextreme, quickly grew to become one of the leading hosting services providers in the Netherlands, serving over 40,000 customers and hosting 100,000 websites in two datacenters. PCextreme has deployed 120 racks of Supermicro server in those two datacenters.

The challenge: Increase business agility to enhance competitiveness

To sustain rapid growth and maintain leadership in the affordable hosting market, PCextreme had to constantly innovate and expand their services to meet new demands. Key challenges included responding to the desire of customers to control their infrastructure without always having to use managed services, as well as achieving the flexibility to scale PCextreme services up and down based on customers’ needs. Given rising energy prices in Europe, power consumption was another primary concern.

Adapting to these requirements called for a cloud solution that could easily integrate with PCextreme’s existing environment, allow them to manage their infrastructure more efficiently and reduce energy costs—all while providing customers the control and flexibility that they demanded.
