But these SBCs will also need to scale on both private and public networks. Gone are the days you can just bring in “big iron” based on your premise to solve a scalability problem. The virtual SBC itself needs to scale within the cloud. You may have specific high end performance requirements regarding the number of sessions the SBC needs to support on a regular basis, or you may have performance spikes that the cloud-SBC would need to be able to meet. Either way, the SBC in the cloud needs to perform at a high level.

And that means the SBC vendor would need to spend significant effort on this front. It doesn’t just happen “automatically”. Whether the environment is AWS, or OpenStack, or something else, each has specific architectural requirements that must be understood and built into the product.
