Navigating Nerve Clusters of Multi-Cloud and Edge Applications: The Importance of Secure Colocation in the New WAN Architecture

Spring 2023

Applications and data are being modularized into microservices and moved to multiple public clouds. In some cases, they are also being distributed to the network edge. They are increasingly being consumed from multiple software-as-a-service (SaaS) providers too. With applications and microservices popping up across all domains, the network should be seen as a growing set of interconnected “nerve clusters” situated where the data is, which could be anywhere along the edge-cloud continuum. The new network needs to be able to securely connect within and between these interconnected “nerve clusters” as well as fundamentally understand how their new application models work and to dynamically extend application policies across the network to wherever the applications are hosted. Carrier-neutral colocation facilities take on a much-expanded role in the age of multi-cloud and are a critical component of the new cloud-optimized WAN architecture. In essence, colocation facilities become an extension of the enterprise WAN, providing visibility, high-performance access and centralized security to multiple SaaS/IaaS/PaaS providers.

This session will explore the latest trends and developments in cloud-optimized WAN, including new technologies, architectures, and best practices. We will also discuss how these solutions can help organizations improve performance, security, and cost-efficiency in their wide area networks.

Session Outline:
-Introduction: The challenges of traditional WAN solutions in the cloud era
-Overview of cloud-optimized WAN solutions and technologies
-Cloud-optimized WAN architecture and design best practices
-Case studies of organizations that have successfully implemented cloud-optimized WAN solutions
-Security considerations for cloud-optimized WAN
-Future trends and developments in cloud-optimized WAN
-Conclusion and Q&A

Target Audience:
IT professionals, network architects, cloud architects, and anyone interested in learning about the latest developments in wide area networking and how it relates to cloud computing.
