Anthos – Build and manage modern hybrid applications
Anthos puts all your IT resources into a consistent development, management, and control framework, automating away low-value and insecure tasks across your on-premises and Google Cloud infrastructure. Within the context of GCP, the term hybrid cloud describes a setup in which common or interconnected services are deployed across multiple computing environments, one based in the public cloud, and at least one being on-premises. A hybrid cloud strategy lets you extend the capacity and capabilities of your IT, without up-front capital expense investments by using the public cloud, as well as preserve your existing investments by adding one or more cloud deployments to your existing infrastructure.
