Earlier this week, I read an interesting whitepaper from AWS about how public cloud providers are moving to 5G and optimizing their services to gain more market share. AWS in this whitepaper covers OpenRAN as one of these technologies, providing useful hints about new services around 5G SA networks. This whitepaper is a technical guide that describes the architecture and best practices for deploying OpenRAN solutions on the AWS cloud. The paper begins by providing an overview of OpenRAN and its key components, including the vRAN (virtual RAN) and CU (central unit), as well as the O-RAN (OpenRAN) Alliance and its goals.

The whitepaper then goes on to discuss the benefits of running OpenRAN on AWS, including the ability to take advantage of the elastic and flexible nature of the cloud to provide cellular services with low latency and high reliability, as well as the ability to reduce the total cost of ownership and accelerate time-to-market.
The paper also provides a detailed architectural overview of a sample OpenRAN deployment on AWS, including the various AWS services that can be used to deploy and operate OpenRAN solutions, such as Amazon Elastic Compute Cloud (EC2), Amazon Simple Storage Service (S3), and Amazon Virtual Private Cloud (VPC). It also covers the different network topologies and deployment options available on AWS.
Finally, it includes best practices for designing and operating OpenRAN solutions on AWS, covering topics such as security, scaling, and monitoring.
Overall, this document provides a comprehensive overview of how to deploy OpenRAN solutions on the AWS cloud and provides valuable information for network operators who are looking to take advantage of the benefits of OpenRAN and the AWS cloud.
