to a facility that hosts servers. In the DOR scenario, Titanium Cloud was tested using a 50-node system. Myriad race conditions were simulated, such as powering off all the nodes at the same time and turning them back on at the same time; or deliberately overloading specific parts of the system to find weak points. Tests prove that OpenStack can withstand start-up storms or DORs and come back on, fully restored, without time-consuming manual intervention. Solution 5: Secure OpenStack over the Internet. The simplest, and most elegant, solution to securing OpenStack over the public Internet was to not use the public Internet. That is, in a vCPE deployment, distribute the OpenStack control and compute nodes together so that they do not have to communicate over the Internet. In Titanium Cloud, the security issue with OpenStack is eliminated because the server is designed to distribute compute and control out to the edge of the network at the customer's premises. Titanium Cloud's design ensures that the control and compute nodes do not need to communicate over the public Internet because they are both in a secure location at the customer premises. The NFV infrastructure still needs to communicate with the orchestration layer, however, and that is handled by leveraging standard IT security techniques, such as VPNs and firewalls, which are likely to be already in place at the customer premises. Rather than have centralized control and distributed compute, Titanium Cloud has centralized orchestration and low-cost distributed control and compute, which creates security and high reliability in a small footprint solution for vCPE deployments. Solution 6: Enable hitless upgrades to ensure compatibility between OpenStack versions. Network operators can keep their clouds and vCPE services up and running even when upgrading to new versions of OpenStack. But they won't find these capabilities in vanilla, off-the-shelf OpenStack. Achieving efficient, carrier- grade reliability in OpenStack upgrades requires optimization and expertise. Titanium Cloud features a comprehensive upgrade solution that includes hitless upgrades, live migrations, and hot patching. In a hitless upgrade, the NFV infrastructure does not have to be taken down and rebooted to complete an upgrade to a new version of OpenStack or a new version of Titanium Cloud. The vCPE services and VNFs remain live during the upgrade so that there is no impact to the business customer's services. Since the VMs are migrated live, there is no service downtime. Titanium Cloud also supports hot patching for minor updates, which can be deployed onto a running system and automatically loaded onto all of the nodes in the system. CONCLUSION OpenStack was not originally designed for telecom networks, but with StarlingX it is evolving quickly to meet all of the requirements for resiliency and reliability that operators demand, particularly at the network edge. Wind River Titanium Cloud, a solution based on open standards and open source software, including StarlingX, meets carriers' needs for interoperability and avoiding vendor lock-in while also delivering the flexibility, performance, and reliability they require. Titanium Cloud is also supported by a strong ecosystem of leading technology providers that enable multiple use cases from the edge up into the core of the network. With Titanium Cloud, the OpenStack obstacles for the edge have been removed, creating a path to deploying open solutions throughout the network that can be put into use today.
