…Network Security Policy Management for Hybrid Clouds

As organizations embraced the public cloud over the past few years, security teams were on the hook to modify network security policies and implement security controls to protect cloud-based workloads. The goal was simple: Protect cloud-based workloads with network security polices and controls that were equal to or better than existing safeguards for physical and virtual servers in corporate data centers. This turned out to be far more difficult than expected.  Many organizations tried to force fit their existing security controls (firewalls, ACLs, network segments, VPNs, etc.) to accommodate cloud-based workloads. This turned out to be a technology mismatch as security controls built for physical and virtual servers were too inflexible to service the public cloud. As an alternative, a lot of firms decided the best bet was to create a customized network security infrastructure for the cloud with its own controls and associated policies. According to ESG research, 70% of organizations use separate controls for public cloud-based resources and on-premises VMs and servers today. To read the complete article, CLICK...

Networking News and Insights from Dell…

The canals, gondolas, and St Mark’s Square in the Venetian Hotel served as the back drop for the first ever Dell Technologies World event in Las Vegas last week. Dell is continuing to execute against its strategy to help organizations execute against their digital and IT transformations. Over the last 20 or so months, it has worked diligently to eliminate conflict in its portfolio and discuss the value of its solutions across the entire family of companies. On the networking front, one of Dell’s key pillars for a modern data center, Dell continues to evolve its disaggregation story (Network OS and Network Hardware) for scale-out data center and campus environments. Dell will continue to partner with Aerohive and Ruckus to provide end-to-end solutions for wireless environments. One of the new proof points for its disaggregated, scalable approach came from a Dell family member, VMware, that announced it will now leverage Dell networking hardware solutions for its NSX SD-WAN appliances.

Enterprise Networks and Telco Clouds on a Collision Course

The Internet of Things will move more processing to telecom suppliers’ facilities. Network engineers have traditionally treated networks managed by their telecom suppliers as outside their immediate domain of concern. The telco network was brought into the data center, appropriate routes or peering set up, and that was it. Enterprise workloads typically don’t run directly on telco networks for many reasons, including governance or compliance requirements. Now, emerging technologies such as the Internet of Things are starting to require workloads to be located within telecom service providers’ facilities. To read the complete article, CLICK...

The Network’s New Role in the Data Center

At RSA Conference 2016, it was apparent to me that networking is performing a significant role in modern infrastructure security with visibility, context and enforcement for modern application workloads. If the network is the nervous system for a data center, we can gain better insights into its health and operation by better network visibility, much like what electroencephalography (EEG) does with brain signals in medicine.

Cisco Acquires Lancope: Great Fit, Great Deal.

I’m not a financial analyst but in my humble opinion, Cisco’s acquisition of Lancope was a true bargain. For less than a half billion, Cisco got an installed base, revenue stream, a mature enterprise-class product, and a very experienced team. To read the complete article, CLICK...
