“With Virtual RAN (vRAN), network functions are virtualized, breaking down silos and minimizing CAPEX and OPEX.” — Anil Bhandari, Vice President of Product Management, Altiostar

For Communications Service Providers (CSPs), there’s a lot of momentum around virtual and open radio access networks (vRAN/Open RAN), but it’s important to first understand the concept. Traditional RAN architectures are proprietary and closed solutions, and this hinders the innovation necessary to rapidly offer new mobile services or scale them as user demands change over time and location.

With open and virtualized RAN, proprietary and expensive hardware are replaced, and you disaggregate the RAN architecture, now providing open interfaces and an ecosystem in which many vendors and solution providers can innovate. 

Virtual radio access networks (vRAN) apply the principles of network function virtualization (NFV), whereby the RAN network functions are now virtualized and deployed on cloud platforms. It brings the benefits of cloud and the ability to take a platform-centric approach by deploying RAN network functions on an agile, scalable and hybrid platform. This breaks down silos and minimizes CAPEX and OPEX.

Another important benefit of a vRAN is that network functions can be flexibly deployed as needed, more dynamically. This is key — especially in the context of 5G — to support higher cell and device density and a wide variety of use cases not limited to physical network functions.

In the above video featuring Altiostar and IBM, you’ll gain additional insights and find answers to these questions

  • Why is vRAN important to 5G and network transformation?
  • How do you address integration, performance and scalability?
  • What role do AI and automation play in relation to vRAN?

Serverless vs. microservices: Which architecture is best for your business?

7 min read - When enterprises need to build an application, one of the most important decisions their leaders must make is what kind of software development to use. While there are many software architectures to choose from, serverless and microservices architectures are increasingly popular due to their scalability, flexibility and performance. Also, with spending on cloud services expected to double in the next four years, both serverless and microservices instances should grow rapidly since they are widely used in cloud computing environments. While…

Seamless cloud migration and modernization: overcoming common challenges with generative AI assets and innovative commercial models

3 min read - As organizations continue to adopt cloud-based services, it’s more pressing to migrate and modernize infrastructure, applications and data to the cloud to stay competitive. Traditional migration and modernization approach often involve manual processes, leading to increased costs, delayed time-to-value and increased risk. Cloud migration and modernization can be complex and time-consuming processes that come with unique challenges; meanwhile there are many benefits to gen AI assets and assistants and innovative commercial models.
