Softswitch on AWS now available

Moving your Softswitch to the Cloud is easier and more important than ever

For many years, communications service providers (CSPs) have been installing, hosting, and operating VoIP Softswitches on bare metal servers. Even when Amazon AWS cloud got popular, yet many communication service providers could not benefit from what the cloud has to offer due to the nature of Voice Over IP (VoIP) traffic. Here is an example of the 7 best benefits that AWS Cloud provides its users that telcos not hosted on AWS are missing today.

From my experience, one of the obvious issues for soft switches and RTP software playing not so well with AWS Cloud out of the box is the Elastic IP Architecture. An Elastic IP address is a reserved public IP address that you can assign to any EC2 instance in a particular region until you choose to release it.

Still, with some hacking around you could get open source Softswitch components to work on AWS, yet it was still not that appealing or worth the effort since AWS has a higher cost than what CSPs are already paying for bare-metal and too risky for experimenting with large production traffic plus all the privacy and regulation concerns.

We did not see any real-world evidence that any serious operator is making the move to the cloud for their core components like a Softswitch.

In 2020-2021 as AWS cloud got a lot better and unicorns like Twilio has proven that AWS is a great choice for auto-scaling communications services and most importantly, it works! We see real evidence that some of the largest operators in the world taking the decision to move their core network components like voice, SMS to the cloud (AWS, Azure, Oracle, Google Cloud).

To me, this translates to that in a couple of years some of the world’s largest telecom operators will be closer to each other than ever, if my predictions are right, due to security, network quality, and other factors it makes sense that operators will make it a standard and give a preference to do business with CSPs hosted on the same cloud vs in traditional networks.
