Cloud computing is now a central piece of enterprise IT estates. According to IDC the share of cloud environments in overall IT infrastructure spend is fast approaching the 50% mark. As IT estates grow and become more complex, CAPEX and OPEX can increase substantially, serving as a catalyst for an ongoing challenge organisations face – to economise infrastructure expenditure.
One strategy enterprises can adopt in order to reduce infrastructure costs is to move away from expensive proprietary technologies to open source platforms. This allows organisations to not only rein in costs, but also to gain more control over their infrastructure.
This paper explores migrating to an open source cloud computing platform – OpenStack – and comparing it with vRealize – the proprietary virtualisation platform from VMware. Moreover, this paper provides an analysis of an organisation with a medium-sized estate of VMs and physical machines, detailing how migrating from VMware to OpenStack can result in up to 92% cost savings.
