Determine which apps are most suitable to run on the cloud.
Deduplication has become a standard feature in storage arrays. Here are some issues to weigh with the technology.
One of my long-time regular readers sent me this question:
I was wondering if you have had any interest in putting together an SD-WAN overview/update similar to what you do with data center fabrics where you cover the different product offerings, differentiators, solution scorecard…
That would be a good idea. Unfortunately the SD-WAN vendors aren’t exactly helping.

As previewed in part six of the Micro-segmentation Defined – NSX Securing Anywhere blog series , independent cyber risk management advisor and assessor Coalfire was sponsored by VMware to create an industry first Micro-segmentation Cybersecurity Benchmark report. Coalfire conducted an audit of the VMware NSX micro-segmentation capabilities to develop this benchmark report detailing the efficacy of NSX as a security platform through a detailed “micro-audit” process, testing NSX against simulated zero-day threats.
Testing included five different network design patterns, and demonstrated how NSX micro-segmentation can provide stateful, distributed, policy-based protection in environments regardless of network topology. Topologies included –
Coalfire’s examination and testing of VMware NSX technology utilized simulated exploits that depict likely malware and Continue reading
Playing in the lab and want to impair a link with delay or loss? I use WAN Bridge – its simple and free.
So say I’m testing an SD-WAN brownout/impairment avoidance solution in my lab. For example, Cisco’s IWAN. I’m going to need something to impair links with delay or loss. I like WAN Bridge. Why? Because its simple, easy, and free.
There has been one thing I’ve struggled with in the past year about. Every time I needed an impairment point this burned up 2 NICs on my UCS equipment. Why? Cause I couldn’t seem to figure out how to load one NIC on a UCS as a trunk port with multiple VLANs on it and have multiple WAN bridges with just 1 trunk on a switch.
So that meant, for a recent CPOC that I was doing, if I really wanted 6 impairment points (red circles in diagram below) I was going to need to eat up 12 NICs on my UCS.
There had to be a better way…..
My friend, David Prall, was convinced it “should” work. I was equally convinced that I had tried it before and Continue reading
