HP CloudSystem  HP CloudSystem is a cloud infrastructure from Hewlett Packard Enterprise (HPE) that combines storage, servers, networking and software. HP CloudSystem is now branded HP Helion CloudSystem and is an integral component of the HPE Helion portfolio. HP CloudSystem was first launched in January 2011. Many of its components are based on earlier HP products. HP CloudSystem is based on HP BladeSystem Matrix technology, which was originally launched in 2009. BladeSystem Matrix is a combination of HP Systems Insight Manager, HP BladeSystem c-Class blade chassis and HP StorageWorks EVA Fibre Channel Storage framework, along with Microsoft Active Directory and virtualization Hypervisors from Microsoft and VMware. HP Insight Orchestration provides the orchestration functionality. Previous versions of HP CloudSystem combined HP Matrix Operating Environment, which manages, monitors and provisions servers for physical and virtual resources and HP Cloud Service Automation Software, a set of system management tools used to provide and manage the lifecycle of IT services. BladeSystem Matrix supports HP ProLiant x64 blades running Microsoft Windows and Linux, and HP Integrity blades running HP-UX. HP CloudSystem is now branded HP Helion CloudSystem and is an integral component of the HP Helion portfolio. The migration of traditional IT, in which IT directly controls IT purchasing, deployment, management, and use, to a cloud computing model holds a number of challenges. A paper titled "Cloud Migration: A Case Study of Migrating an Enterprise IT System to IaaS," by researchers at the Cloud Computing Co-laboratory, School of Computer Science, University of St Andrews, raises several socio-technical issues related to the migration of IT services to the cloud. The researchers state that in-house IT personnel are at risk of becoming dependent upon the cloud service vendor, of which the user organization has no control over. The researchers also note that the user organization could also require more resources to carry out migration to the cloud and overcome the issues that could crop up after migration, such as a lack of in-house knowledge of cloud operations. The researchers also note that the user organization's customer representatives could take longer to resolve customer problems, as their questions may require input from the external cloud services provider. Furthermore, migrating to cloud computing could reduce job satisfaction among IT staffers, whose jobs change from a hands-on technical role to managing external service providers. User organizations must also learn to cope with a new way of managing IT as they are no longer in charge of software support contracts or hardware maintenance issues.
