Die Innovationskraft von Entwicklungsteams steigt, da mit Open Source-Technologie mühelos branchenführende Lösungen von zahlreichen Anbietern miteinander verbunden und aufeinander abgestimmt werden können. Das Ziel besteht darin, neue Netzfunktionen, Features und Technologien einzubinden. Außerdem werden durch Open Source-Support für Container und Methoden wie Agile, DevOps und CI/CD Deployment und Lifecycle-Management-Intervalle erheblich verkürzt. </span></p><p dir="ltr"><a href="/de/topics/containers/what-is-kubernetes-vb"><span>Kubernetes</span></a><span> ist die vorherrschende Technologie für die Orchestrierung von Container-Infrastrukturen mit </span><a href="/de/technologies/cloud-computing/openshift"><span>Red Hat® OpenShift®</span></a><span> als einer führenden kommerzieller Kubernetes-Lösung. Red Hat OpenShift bietet Verwaltungsfunktionen für cloudnative Netzwerkfunktionen wie SD-WAN. Die Integration zwischen Red Hat OpenShift und SD-WAN-Lösungen des Partnernetzwerks von Red Hat vereinfacht die Konnektivität zwischen Kundenniederlassungsinstallationen mit Private- und Multi-Cloud-Infrastruktur.
