I am Monika Machado, the Director of Border and Backbone Engineering on the Oracle Cloud Infrastructure Backbone team, and this is the first in a series of blog posts about the Oracle Cloud network backbone.
Oracle Cloud Infrastructure regions rely on a state-of-the-art network technology and design. Each region is composed of availability domains that are interconnected by a metro-area network, and the regions are interconnected by a dedicated, custom-built network, the Oracle Cloud Infrastructure backbone.
This post provides a high-level overview of the backbone, the use cases that it serves, and how it can enable your enterprise workloads in Oracle Cloud Infrastructure. Future articles will focus on specific use cases and offer additional insights into the technologies used to realize our high-performance backbone.
The OCI backbone was designed to enable customer workloads by providing a high performance, reliable and scalable transport. The backbone is a dedicated, secure network for interconnecting Oracle Cloud Infrastructure regions in diverse geographic locations. The backbone network provides privately routed inter-region connectivity with consistent inter-region performance for bandwidth, latency, and jitter when compared to the public Internet. This enables enterprise workloads that typically don't work well over the internet, including disaster recovery, real-time replication, clustering, and other scenarios.
We designed and built a modern and smart backbone from the ground up to enable the enterprise use cases that our customers demand. The backbone interconnects all Oracle Cloud Infrastructure data centers and provides high-performance and reliable connectivity between data centers.
As of May 1 2018, all the Oracle Cloud Infrastructure regions are connected to the backbone, and you can utilize it for your applications needs.
All the communications traversing the backbone are secured by industry-standard encryption protocol, which ensures confidentiality for all transactions between the Oracle data centers. With this level of encryption, you can be assured that your data is protected while in transit on the backbone.
Because any physical infrastructure is subject to some type of failure, the backbone is designed to route around failures to maintain the availability of the connections between the data centers. In case of failure, all your applications that use the backbone will be rerouted to new paths without being disrupted.
Our engineering teams put a lot of effort in making sure automation was ready for all the aspects of building the backbone, this includes automation on the planning for the fiber routes, device deployment and maintenance and operations. We are making every effort to remove human failures from the engineering perspective.
The Oracle backbone enables you to create solutions that span multiple regions such as multi-region VCN peering, high-availability applications, and seamless replication for your data. The backbone also provides transit between a backbone point-of-presence (POP) location and the rest of the Oracle Cloud Infrastructure data centers to extend the connectivity for Oracle Cloud Infrastructure FastConnect service customers.
My team and I look forward to continuing the dialogue on the next post in the series.
