Why customers choose Oracle Cloud Networking and Connectivity

Lowest network pricing

OCI offers low networking prices that enables enterprises to move significant volumes of data—such as live video streaming, video conferencing, and gaming—at very low costs. Inbound data transfer is free, and OCI offers 10 TB of outbound data transfer at no cost.

Oracle Cloud economics

Flexible load balancing

OCI Load Balancing enables enterprises to distribute web requests across a fleet of servers or automatically route traffic across fault domains, availability domains, or regions. This yields high availability and fault tolerance for any application or data source. OCI’s Flexible Load Balancing provides instant readiness and dynamic scalability for your workloads.

Introducing global connectivity and enhanced cloud networking with the dynamic routing gateway

Dusko Vukmanovic, Sr. Principal Product Manager, Cloud Native Services, Oracle

"OCI Service Mesh is a free managed service that provides security, observability, and network traffic management for your cloud native applications without requiring any changes to the applications. The fully managed service makes implementing these capabilities simple for any organization, regardless of size.

Cloud native applications are commonly comprised of several interconnected microservices that, in tandem, deliver the application experience. Therefore, the reliability of each service is critical, and organizations must manage security, observability, and connections across all microservices."
