A clear advantage: open source opens up the possibilities of the cloud

Giving businesses choice when it comes to the cloud by using open-source software can help them become more flexible and allow them to use the applications they wish to use to deliver services to their customers.


When it comes to cloud computing, OpenStack and Linux are key strategic imperatives for companies because of the flexibility in solution choice they both provide. While cloud computing is on the agendas of business and IT leaders for its ability to increase business agility, a one-size-fits-all solution doesn’t exist. Regardless of the approach taken by companies, the starting point is the choice of public cloud, private cloud, or both.

Brian Green, managing director at SUSE UK & Ireland, says: “Enterprises today want as much choice as possible and Linux helps them achieve that in the public cloud. By embracing Linux, companies can reduce vendor lock-in and achieve the freedom to run workloads on their preferred public cloud.”

The public cloud provides companies with pay-as-you-go pricing and on-demand usage by renting and deploying solutions by the hour on third-party infrastructure. This model of computing not only provides near-instant access to required resources and solutions, but also lowers overall costs by shifting server procurement from a capital to an operational expense.

However, the public cloud is not without negatives.  Many IT leaders fear losing control over their businesses’ data and are worried about potential security and compliance risk associated with deploying critical workloads in the public cloud.

Pete Chadwick, senior product manager, cloud solutions at SUSE, stated: “Companies can easily take advantage of the public cloud for use cases that are not core to the business – where compliance and control over data is less important.”

Conversely, private clouds enable organisations to keep data behind the corporate firewall and use traditional enterprise security and compliance methods. Although IT organisations continue to manage the infrastructure, the automation and self-service capabilities of a private cloud enable them to improve business agility while lowering costs through improved resource use.

Chadwick says: “What is driving enterprise interest in private cloud solutions is that customers can take advantage of a lot of the same benefits provided by the public cloud model, without the loss of IT control.”

With open-source cloud software such as OpenStack, which has a vendor ecosystem over 400 strong, companies can reduce vendor lock-in and maximise their options for building a private cloud. With SUSE Cloud this is especially true. SUSE Cloud is an enterprise OpenStack distribution that supports mixed KVM, Xen, Microsoft Hyper-V, and VMware vSphere environments. This enables customers to expand their hypervisor choices and allow them to optimise workload performance, while minimizing licensing costs. Additionally, SUSE works with the OpenStack ecosystem to support and integrate its solutions with SUSE Cloud through standard open APIs. This modular approach helps ease installation and management of complete enterprise-ready private cloud solutions today, while providing IT organisations with future flexibility.

Said Green: “SUSE’s open-source solutions make it easy to adopt cloud. Whether running SUSE Linux Enterprise Server on Amazon EC2, deploying an OpenStack-based SUSE Cloud private cloud, or using a combination of SUSE and partner solutions to build a hybrid cloud, our customers can deliver the right solution to address their business objectives.”
