Security in Cloud Networking

Enterprises are grappling with security in their infrastructure and many point products try to solve this in different use cases. As enterprises migrate from north-south to east-west traffic patterns, the need for consistent security across cloud-network and firewall infrastructure is paramount. Furthermore, additional security concerns emerge as organizations contemplate leveraging access to the public cloud…

Mainstream Cloud Networking with Flexible Ethernet

Networking vendors have long touted distinct routers and switches with different LAN and WAN interfaces. Remember IBM Token Ring versus Ethernet? Or ATM or Sonet versus Ethernet or more recently Fibre Channel SANs versus Ethernet? Ethernet truly addresses the present state and next generation of networking, usually obsoleting the alternatives. Ethernet has proven its evolution…

Why Java APIs and Industry-Standard CLIs are Different

In the past few years, the tech industry has watched with increasing concern as various entrenched participants have brandished copyright law as a weapon to stifle competition and innovation. Recently, we have been treated to yet another novel claim: that after over a decade of broad adoption, the industry-standard set of commands that a user…

The Game Changer in Cloud Networking

The networking market is at an exciting pivot point, evolving away from legacy enterprise networking to the cloud. While the public cloud providers (“titans”) may take a “do it yourself” approach to engineering cloud network designs, mainstream enterprises demand a “cloudified” turnkey solution and want to emulate cloud operators. The increasingly massive scale of address…

Converged Cloud-Class Networking – The Next Frontier

Scale-out cloud-applications continue to be the most disruptive force to traditional network architectures in the data center. They demand an open and uncompromised cloud network, unshackled by monolithic and the prehistoric proprietary networks. Our customers and partners are reshaping this traditional networking industry. Previously burdened by monolithic software and underperforming hardware, the new evolving bifurcation…

Software Stack Choices in Cloud Networking

The networking industry is changing rapidly with demand for more dynamic control of big data, and scale-out cloud applications. The inevitable shift to software-defined workloads and workflows is crystal clear. This calls for more “disaggregation” of software models for the network stack. Should networking move to a more open standards-based approach or continue with legacy…

Relevance of SDN in Cloud Networking

SDN (Software Defined Networking) is finally becoming clearer. It is not “Still Don’t Know” nor is it a specific overlay controller. Simply put, it is an open and programmable way to build networks for customers looking at utilizing hybrid combinations of public and private cloud access. We are witnessing a shift from multi-tier oversubscribed legacy…
