Rakuten Mobile CTO: Telco Software ‘Absolutely Flawed’

Rakuten Mobile CTO Tareq Amin claims none of the operator’s infrastructure is underperforming, but telco cloud software is thus far failing to meet the moment industry wide.
“Despite so much hype around virtualization, the underlying architecture of the software platforms that are used, whether it is IMS [IP multimedia subsystem] core, policy functions, OCS [online charging system] function, there is not a single vendor in the world that supports elasticity,” he said during a group chat with analysts and press.
“It is not good enough to move the software architecture from monolithic architecture that was built on proprietary hardware and say I’m going to shift to a virtual machine. To achieve the dream and the benefits of cloudification, the software architecture must evolve to support elasticity,” Amin said.
Moving a telco workload to the cloud does not enable elasticity, he explained. “There is no magic that an Amazon Web Services, Google, and Microsoft could enable because the underlying software architecture is absolutely flawed. It needs to evolve,” he said.
“I don’t think the industry as a whole has forced the vendors to advance the software architecture in the same way enterprise and over-the-top players have advanced. Auto elasticity does not exist. Orchestration in a way that you want it holistically across the network doesn’t exist,” Amin said.
No telco software is meeting “Rakuten’s objective for auto elasticity as a network function across multiple geographies with auto-healing enabled,” he said, adding that the operator is pushing vendors to “think like an enterprise IT company, not necessarily a legacy IT software provider.”
Rakuten’s telco workloads are performing as expected, but Amin said he isn’t happy that those workloads still don’t meet his definition of cloud-native architecture. “We still have a lot of work to do with the industry and ecosystem to push this modernization of the software stack to move into the right destination for auto elasticity, auto healing, resiliency, and so on, into the fabric of the cloud networks.”
