Top Questions From Our Micro-segmentation with NSX Webinar

johnkruegerLast week we held a webinar on Micro-segmentation with VMware NSX where VMware Certified Instructor John Krueger discussed the major features and capabilities of VMware NSX 6.1 and how in a software defined data center, a zero trust security model becomes achievable when taking advantage of features in VMware NSX. The conversation led to several questions, some of which we wanted to share with you.

Where can find step-by-step instruction for installation & configuration of NSX on ESX host?
Please see the NSX Installation and Upgrade Guide

What about network tools (reporting, monitoring, …) are they provided by NSX?
NSX provides Flow Monitoring for watching traffic through the Distributed Firewall. There is also a packet capture utility built into ESXi that is VXLAN aware, and can capture traffic at any point from the vNIC egress to physical uplink egress, and most points in between. NSX can take advantage of that capture utility and provides a traceflow function to capture and allow you to analyze traffic from one VM all the way to another across the Logical Network. NSX also provides auditing and logging for administrator activity. VMware provides a Management Pack for vRealize Operations Manager for deep insight into NSX, its Logical Network topologies and components, and a Content Pack for vRealize LogInsight for a more visual syslog analysis.

If NSX extends the L2 boundaries of a Data Center, how does redundancy and configuration protection works between two data centers? Will only one NSX Appliance manage both data centers? Or will each DC have its own NSX appliance? 
If I have multiple physical sites managed by a common vCenter Server, the NSX Manager will exist only in one site (likely on your management cluster). Because NSX has a 1-to-1 relationship with vCenter Server, if I have multiple NSX Managers, that implies multiple vCenter Servers. There is currently no synchronization between them.

NSX has to go through physical hardware to get to a different ESX host. Routing and firewall make a lot of sense to do at the hypervisor level but what are some of the benefits on the switch level if you still have physical hardware?
Because the routing and firewalling happen within the hypervisor, the network requirements for the physical infrastructure are lessened, making the physical easier to operate, less of a touch point, and a more stable asset.

Is the micro-segmentation concept based on the VXLAN VNI separation? Or is it more of an NSX logical segmentation on top?
Micro-segmentation is based on the fact that we can now provide security filtering at the virtual NIC, so that each NIC is now segmented and protected within the environment.

What is future of existing network engineers with introduction of VMware NSX?
I think they have a very bright future. Generally, the network engineers will be the ones managing the virtualized networks, not the vSphere administrators.

New Dates Set for VCDX Workshop Online

VCDX merchOur VCDX Workshop is one of the most popular ways we help people get ready for the VMware Certified Design Expert (VCDX) design defense. However, we know that not everyone can make it to one of the live sessions in person, so we’re going to deliver a shortened version of it via WebEx throughout the year too. We’ve just added two dates to the schedule for May:

If you’re not familiar with the Online VCDX Workshop, it’s a semi-interactive session is a complete and engaging deep dive into the VCDX Process providing tips and success strategies for: solution design selection and development; the VCDX application and supporting documentation; creation and delivery of the design overview; the VCDX design scenario; and the VCDX troubleshooting scenario.  For the online webex version all audio will be broadcast, and questions will be asked and answered real time via the WebEx Q&A window.  Like the Online Q1 VCDX Workshop this will also be recorded and posted to VMTN.

If you’re pursuing the VCDX certification, the VCDX Workshop is the perfect start to your journey. Unlike the live events where space is limited, the online sessions are unlimited – but we do ask that you register using the links above so we know who’s interested.

I look forward to you joining us in May!

IDC Whitepaper Confirms Value of IT Training

IDC WP_Screenshot CoverThe verdict is in. IT Training is critical for organizations who want to achieve tangible benefits from a software-defined data center (SDDC). In the new VMware-sponsored IDC whitepaper “Software-Defined Datacenter: Evolving Datacenter Management and IT Skills”, IDC Analyst Cushing Anderson discusses the link between IT training and recognizing the business benefits of an SDDC including:

  • Accelerated time to value
  • Higher system resiliency
  • Optimized IT and staffing spend
  • Increased IT staff focus on innovation

Here’s a sample of what else you’ll find:

“With a properly designed and deployed SDDC managed and optimized by well-skilled staff, organizations can realize a range of performance benefits.” (p. 9)

“These benefits can be realized only by accelerating the evolution of the datacenter, which involves transforming technology, transforming processes to manage the datacenter, and transforming the IT staff with increased and ongoing training.” (p. 10)


Cushing Anderson, IDC Program Vice President Project-based Services, speaks on a variety of topics including business consulting drivers, talent and the impact of certification on organizational performance. He has authored a number of IDC publications on IT Training and Certification including the “Worldwide and U.S. IT Education and Training Services 2014–2018 Forecast.”
