In fünf Schritten zu einer Virtual Private Cloud [30.07.2014]

Richtig konzipiert, lassen sich Cloud-Technologien nahtlos und transparent in bestehende Infrastrukturen integrieren. Dies kann etwa beim Aufsetzen einer Backup-Website, in Testumgebungen oder für Big Data-Anwendungen äußerst hilfreich sein. Was also, wenn die Cloud wie ein eigenes neues Rechenzentrum wäre? Die Schaffung einer Virtual Private Cloud erlaubt es, verschiedene technologische Dienste zu nutzen, die in herkömmlichen Rechenzentren nicht verfügbar sind. Der Fachartikel erläutert, wie Sie in fünf Schritten und kaum fünf Minuten ein neues Cloud-RZ erstellen. [mehr]
