be served as a fluid, elastic resource. ‘In recent years, we are starting to see the same disruptive transformation in the rest of the infrastructure stack,’ he explained. ‘Architects of modern cloud data centres are embracing a new approach to infrastructure characterised by scale-out resources that use commodity hardware and rich policy-based automation. Tis emerging architecture is called the soſtware-defined data centre.’ He added that open cloud platforms such as OpenStack are democratising cloud-building efforts, and that companies are using these platforms to deploy both private and public clouds rapidly using infrastructure from a variety of vendors without getting locked in. Tis rapid deployment is a particularly


attractive aspect for any industry that has dynamic workloads as the need for

additional infrastructure can be satisfied within the hour, rather than aſter a lengthy procurement process and subsequent deployment. ‘Cloud customers want to be able to consume resources quickly and easily as and when required. In order to deliver this level of agility and elasticity, cloud builders need infrastructure that offers scale-out


architecture and rich automation capabilities,’ Kress commented.


‘Administrators need


to be able to scale storage capacity and performance in multi-tenant environments for a wide range of workloads, without creating silos that are difficult to manage. Tis in turn requires end-to-end visibility across compute, network, and storage layers to enable troubleshooting and service-level agreement (SLA) remediation.’ He continued by saying that to deliver


one-click cloud services, storage management needs to move to policy-based automation integrated with the control plane across the entire compute, network, and storage stack. ‘Legacy storage architectures, which are rooted in rigid mainframe-era designs, are ill suited to meet the demands of the dynamic, shared modern data centre,’ he added.
