Cloud Computing: Deploying Open-Source Cloud Systems: 5 Pros and 5 Cons
Open-source cloud frameworks have made a major splash in recent months with big players such as Rackspace/NASA, Hewlett-Packard, VMware and Citrix backing major open-source cloud initiatives like OpenStack and CloudStack. As these major vendors continue to build out their public cloud infrastructure to battle with the incumbent services leader, Amazon Web Services, there are some underlying questions about whether the same technologies are ready for the enterprise. After all, open-source cloud system deployments are only a few years old, without a lot of use cases in production at this time. Although a number of first-mover-type enterprisessuch as telecoms, financial services providers, scientific laboratories and media companiesare already comfortable with the alternative open-source cloud systems, not many smaller and midrange companies know much about them. In an effort to bring our readers a balanced view of this topic, eWEEK has assembled this slide show based on information from Floyd Strimling, technical evangelist at Austin, Texas-based Zenossa provider of unified IT operations software for physical, virtual and cloud-based IT infrastructure, to examine the pros and cons of deploying an open-source cloud for an enterprise of any size.
Pro No. 1: Flexibility
By definition, open-source clouds offer a higher degree of flexibility than their proprietary rivals. Rather than simply reading manuals or attending training sessions, customers can read and modify the code itself and participate in various projects by contributing software code, starting a related open-source project, providing documentation or holding free seminars.Â Interacting and learning from the broader community provides customers more flexibility in their cloud designs and provides innovative internal or external offerings.
