VMware’s Virtual Cloud Network And The Emphasis Towards Networking

Dell EMC world is underway and new announcements and products are expected. Well, seems like we weren’t disappointed with VMware’s announcement introducing the Virtual Cloud Network.

VMware’s Virtual Cloud Network is built on technologies such as NSX and is an agile network and security fabric that connect apps, data and users regardless of their placement. This means apps running on AWS, GCP and private cloud can be brought under one network and security fabric simplifying scope of security and management. VMware is pushing towards the idea of having a singleton network fabric that can extend to multiple clouds and environments. The aim here is to have network evolve into a secure, programmable and a flexible fabric.

VMware’s virtual cloud network suite of products consists of,

  1. NSX SD-WAN – Powered by the recently acquired VeloCloud,  NSX SD-WAN provides the solution for connectivity and security across WAN. With NSX driven SD-WAN, you can now extend segmentation beyond your datacenter and seamlessly into multiple clouds/endpoints.
  2. NSX Cloud – Provides network and security solutions for public and private clouds.
  3. NSX Datacenter – Provides networking solutions for within the datacenter including containers and bare metal environments.
  4. NSX Hybrid Connect – Enables connectivity and seamless mobility between private and public clouds.

The Emphasis Towards Networking – VMware is finally coming in with a complete suite of networking products as it sets its sights on raising its profit margin by dominating the SDN market. For many years VMware was seen as a company that did not get networking right and VMware with the launch of Virtual cloud network is changing that perception. VMware, recently has been noted to have earned significant business with NSX and these investments into networking are a clear sign that network and security are part of the inner circle that is crucial for VMware’s success.

Analysts estimate that the network and security market will grow at a compound annual growth rate of 4.74% from 2017 to 2022 and the market today is estimated to be around $5 billion and growing. With VMware taking the prime spot of being the leader that ties in network and security across multiple clouds, it shouldn’t be a surprise if it takes a bigger chunk of the network and security market.

CAN VSAN NETWORK RUN ON VXLANS?

An interesting question, if VSAN networking can be done/configured on VXLANS backed by NSX?

The answer is No and this is to avoid a circular dependency.

“However, very often, the question of compatibility is asked in the context of being able to place the vSAN network traffic on an NSX managed VxLAN/Geneve overlay. In this case, the answer is no, NSX does not support the configuration of the vSAN data network traffic over an NSX managed VxLAN/Geneve overlay. This is not unique to vSAN. The same restriction applies to any statically defined VMkernel interface traffic such as vMotion, iSCSI, NFS, FCoE, Management, etc.

Part of the reason for not supporting VMkernel traffic over the NSX managed VxLAN overlay is primarily to avoid any circular dependency of having the VMkernel infrastructure networks dependent on the VxLAN overlay that they support. The logical networks that are delivered in conjunction with the NSX managed VxLAN overlay are designed to be used by virtual machines which require network mobility and flexibility.”

VMware Security Advisory

VMware blog announced a security advisory today.

The advisory documents a hard to exploit denial of service vulnerability in the implementation of the OSPF protocol in NSX-V Edge (CVE-2017-4920). This issue is present due to incorrect handling of link-state advertisements (LSA). NSX-V Edge 6.2.8 and NSX-V Edge 6.3.3 address the issue.

SDDC Era …

A post that went online on Monday.

Been preoccupied lately with loads of work and SDDC stuff but time to get back to sharing and caring!

The Software-Defined Data Center Era is Here

So Sensitive… vRA

vRA is very sensitive. All the users, all the permissions and all the DEM workers have to be all set and happy or else you will start missing tabs in vRA which causes you to break your head.

I started missing the Reservations tab and it was frustrating! Yes it was.

There was this decent KB that made me realize how important it is to add users and connect to their appropriate permissions in vRA.

Here is the KB article.

New NSX Versions

Learning VMware NSX – The Book!

Learning VMware NSX, Ranjit Singh Thakurratan, eBook - Amazon.com 2016-01-31 23-27-52My first book about deploying and using VMware’s NSX network virtualization platform is out for pre-order. It was indeed a challenge to write a book.

I spent most of last year writing the book and its finally all set to release soon. It has been an interesting but tough journey and writing the book wasn’t easy at all!  Adding to the challenge was the fact that the publisher wanted to keep the book to less than 200 pages. That however was a blessing in disguise, more readers will be willing to read a quick 200 page book about NSX rather than a 600 page gorilla.

The book is available on Amazon and is published through Packt Publishing. The kindle version is available now with the paperback shipping in early March.

Below are some highlights about the book,

vSphere HTML Host Client (Updated!)

**Did the original post a while back but there are new updates as picked up from virtual-alan**

Updates

  • Add a new CD/DVD drive to a new or existing VM

  • Add a new network adapter to a new or existing VM

  • Add a new hard disk to a new or existing VM

  • Create a VM from a cluster

  • Migrate compute resource of a VM to a cluster and set vMotion priority

  • Change Agent VM settings for a Host

  • View Lockdown Mode in Security Profile settings of a host

  • View Certificate information for a host

  • Add a new cluster workflow (basic)

  • Remove a cluster

If you love the improvements in the web client, or may be you are a linux shop wanting to test or play with VMware ESXi and wished you could manage your ESXi host with a web client and not with the windows c# client then we may just have a solution for you!

This is my host now (no vCenter)

VMware ESXi - localhost.localdomain 2016-01-17 13-54-51

Meet ESXi Embedded host client! This tech preview VIB will do wonders for you! Once you install this VIB (Vmware install bundle) you will get your web client up and going. Now you can’t use this to manage your vCenter so watch out there.  This is still a tech preview so don’t deploy this in production is my advise although I won’t tell if you don’t! And if you are wondering – this vib was written in HTML and Javascript.

Some of the things you can do with this fling,

  • VM operations (Power on, off, reset, suspend, etc).
  • Creating a new VM, from scratch or from OVF/OVA (limited OVA support)
  • Configuring NTP on a host
  • Displaying summaries, events, tasks and notifications/alerts
  • Providing a console to VMs
  • Configuring host networking
  • Configuring host advanced settings
  • Configuring host services

So basically everything you can do with a c# windows client. This is awesome especially for *nix users!

Below is the process to install it in your host. Do this at your own risk 🙂

  1. Download the offline bundle from here.
  2. SCP this into your standalone ESXi into a /tmp directory
  3. SSH into your host and install the VIB with the below command.

    >esxcli software vib install -v /tmp/esxui_signed.vib –force

  4. Log out and go to httpps://hostip/ui

Below is how it looks to me.

VMware ESXi - localhost.localdomain 2016-01-17 13-59-20

My opinion is this is a good progress and this feature would be great. At the end there shouldn’t really be need for a vCenter to provide a rich web interface.

Teaser – Learning VMware NSX – Virtxpert Repost

I have been working on my book for a while now and have picked two of the best reviewers to keep me honest. The book is about VMware NSX and is the only NSX book as far as I am aware(that isn’t focussed on certification only). 

The book is now available for pre order and below is what Jonathan from www.virtxpert.com has posted. Enjoy the read.

I have been fortuneate enough in my day job to get hands on experience with VMware NSX, even before the bits were available to download I was supporting NSX via the Federation Enterprise Hybrid Cloud, as it is one of the core components. For people still looking to get a jump start on learning NSX, I wanted to give you a bit of a teaser for an upcoming book by Ranjit Singh – Learning VMware NSX.

  

Since I am a technical reviewer for this book, which is being published by Packt Publishing, I can’t give away to much but can tell you it is packed with step by step examples on how to get up and running quickly with NSX and understand the various components and how they interact. Keep an eye out on the Packt site, and I expect you’ll here more from me and @rjapproves when it is released!
