Cloud computing, end-user mobility technologies, and new delivery models have all directly impacted the modern data center infrastructure. In fact, enterprise IT departments are under constant pressure to meet user and application demands, aware that cloud deployments offer an easier and faster alternative but often pinned down by legacy deployment models. The problem stems from the inability of those legacy models to adapt to meet expectations for rapid provisioning, continuous delivery, and consistent performance across multiple environments.
Current data center platforms now span many logical nodes where resources, data, and users are shared between infrastructures. When it comes to delivering applications, the challenges of performance, security, and reliability have not changed. What have changed are the environments and conditions under which those challenges must be addressed…
In particular, the extension of the data center into cloud environments poses significant obstacles to IT operations trying to maintain consistent policies between data center infrastructure services and those in the cloud. Without architectural parity between the environments, applications may execute without consistent policies for security, performance, and availability. The results include increased risk, unpredictable performance, and loss of control over user satisfaction…
