Architecture.
Oracle's public and government cloud is offered through a global network of Oracle-managed data centers, connected by an Oracle-managed backbone network. Oracle's Exadata Cloud at Customer leverages this network for control plane services. Oracle deploys their cloud in Regions, typically with two geographically distributed regions in each country for disaster resiliency with data sovereignty. Inside each Region are at least one fault-independent Availability Domain and three fault-tolerant Fault Domains per Availability Domain. Each Availability Domains contains an independent data center with power, thermal, and network isolation.
Oracle Cloud hosts customer-accessible cloud infrastructure and platform services, as well as end-user accessible software as a service from these cloud regions.
Developer community.
Oracle Developers is a forum responsible for engaging with the developer community that provides information, documentation, and discussion that is authored both by Oracle and by the community members at large.
