Enterprises stick with private cloud systems

This week, bloggers examine why private cloud systems will remain more popular than the public cloud, discuss Google's BeyondCorp project and look into Intel's virtualization push.

Ethereal Mind blogger Greg Ferro says he is skeptical about all the talk surrounding the soaring adoption of the public cloud. Instead, he sees private cloud systems still holding considerable sway among enterprises. For most companies, building private cloud systems makes the most sense -- there is simply too much data in their data centers to migrate easily, and an OpenStack platform is preferred over VMware SDDC.

Ferro labels shortsighted those IT managers who believe it's a good idea to shift data from private cloud systems to the public cloud. Most IT infrastructure professionals do not work on the public cloud, but public cloud providers continue to make high-profile announcements in an attempt to compete for attention. Ferro notes that compute follows data and that open source software will continue to gain traction in IT infrastructure.

Building the software defined perimeter

Jon Oltsik, an analyst with Enterprise Strategy Group in Milford, Mass., examines Google's BeyondCorp project, an example of a "black cloud," or software defined perimeter (SDP). SDP systems originated with the Defense Information Systems Agency and are now propelled by the Cloud Security Alliance, generating networks that run a secure architecture with public key infrastructure or multifactor authentication to authenticate trust relationships between source and destination.

According to Oltsik, Google is joining companies like Cisco that already offer SDP tools. Network access control (NAC) is a close cousin; offerings from Bradford Networks, ForeScout and Pulse Secure bear watching. Startup Vidder offers a commercially available SDP product. SDP's benefits are appealing; Oltsik adds that 49% of enterprises responding to an ESG survey want to require user and device authentication for network access control.

Intel explores networking anew

Packet Pushers blogger Drew Conry-Murray recently wrote about Intel's network ambitions. According to Conry-Murray, Intel is in the midst of "aggressively" positioning itself to become the dominant platform in virtualized networking. Intel sees server CPUs playing an expanded role in network functions, ranging from running virtual switches within an OpenStack cloud to hosting firewalls.

To drive this transformation, Intel has showcased a number of tools including the Data Plane Development Kit (DPDK), an open source offering intended to optimize Intel processors for packet processing. Conry-Murray adds that Intel is also looking into NFV, software-defined infrastructure, and it is beginning to promote HyperScan software that speeds up deep packet inspection.
