NSX Advanced Load Balancer (ALB) – Part 1 – Basic Virtual Service – Initial Setup, Prerequisites and Creating an NSX-T Cloud

Reading Time: 6 minutes

VMware NSX has offered load-balancing capabilities since its inception as VMware NSX for vSphere v6.0 way back in October 2013. Since then, the technology was superseded by VMware NSX-T 1.0 in May 2016 (later rebranded to VMware NSX-T Data Center (v2.2) and again to VMware NSX (v4.x)), thanks to VMware’s $1.26B acquisition of Nicira in 2012. VMware NSX-T brought us (and still does) truly hypervisor-agnostic networking, security, and native load-balancing capabilities.

In 2019, VMware acquired Avi Networks, leaders in software-defined application delivery services for the multi-cloud era. Furthermore, the VMware NSX Advanced Load Balancer (v18.2) was announced in November 2019 following this acquisition.

So, what about the NSX native load balancer? VMware will deprecate this feature in an upcoming release of VMware NSX (likely 5.x), but see below update for more information), however, no date has yet been released. However, VMware advises that customers take appropriate steps to migrate to the NSX Advanced Load Balancer (for which there is a free tier with appropriate VMware NSX licensing) as soon as possible.

London VMUG – 13th July 2023

Reading Time: 4 minutes

Ask anyone. They’ll tell you the same, ‘That Gareth chap loves a VMUG event!’ They’d be correct too.

I’ve been a member of the VMware User Group for some time now, a group of technologists eager to share their thoughts and passion for VMware products. However, the vCommunity (as we put it) can also help as a sounding board for your technical issues, etc., so what better way to meet up with like-minded individuals than at these fantastic VMUG events? A fantastic day catching up with fellow VMUG members as well as a few fellow vExperts and vExpertPROs!

VMware NSX for vSphere to NSX-T Migration – End-to-End User Defined Topology – Config Translation Failed – Reason: Topology Plugin

Reading Time: 3 minutes

In a previous post focusing on the VMware NSX Migration Coordinator (VMware NSX for vSphere to NSX-T Migration – End-to-End User Defined Topology), I detailed the end-to-end process required to migrate VMware NSX Data Center for vSphere (NSX-V) to VMware NSX-T Data Center (now simply VMware NSX as of 4.x) and, more specifically, the ‘User Defined’ option, which allows customers to map NSX-V Edge Services Gateways (ESGs) and Distributed Logical Routers (DLRs) to NSX-T components (e.g., Tier-0 or Tier-1 Gateways). To perform this mapping, customers can either a) upload a pre-defined JSON file or b) use the NSX UI to select the appropriate Tier-0/Tier-1 Gateway via drop-down menus.

The previous post utilised VMware NSX Data Center for vSphere 6.4.13 and VMware NSX-T Data Center 3.2.1, however, labbing this in readiness for an upcoming customer engagement required VMware NSX Data Center for vSphere 6.4.14 and VMware NSX (formerly NSX-T) 4.0.1.1; herein lies the identification of a possible bug when using the UI to map ESGs/DLRs to Tier-0/Tier-1 Gateways.

VMware NSX for vSphere to NSX-T Migration – End-to-End User Defined Topology

Reading Time: 12 minutes

Article Updated: 20th July 2023

In my previous post, I covered the end-to-end migration of VMware NSX for vSphere to NSX-T Data Center (VMware NSX from v4.0.0.1) via the Fixed Topology Option, however, in real life I don’t see this option utilised very often due to the limited number of supported topologies.

How then can we achieve the same in-place, end-to-end migration of unsupported topologies? This is where the User Defined Topology option comes into play, and it offers much greater flexibility by enabling customers to define/map their own logical routing topologies. This, of course, will require a design and, like the message I tried to impart in my previous post, this must be planned ahead of your proposed change/maintenance/migration window.

VMware NSX for vSphere to NSX-T Migration – End-to-End Fixed Topology

Reading Time: 9 minutes

In a previous post, we discussed the value of pre-migration validation checks, identifying whether a customer environment is aligned to the supported fixed topologies and the process of creating and viewing the JSON output following the successful import of NSX for vSphere configuration.

In this post, we continue on the same theme and will use the NSX-T (VMware NSX from v4.0.0.1) Migration Coordinator to migrate an NSX for vSphere environment, end-to-end, to NSX-T via the Fixed Topology option.

VMware NSX-T Migration Coordinator Report Export for Fixed Topology Migration

Reading Time: 4 minutes

With VMware NSX for vSphere (NSX-V) having gone end of general support on January 16th 2022, there are numerous customers now busily working on migrating to VMware NSX-T Data Center (VMware NSX as of v4.0.0.1).

In future posts, I will detail the end-to-end migration process for both Fixed and User Defined Topologies utilising the NSX-T Migration Coordinator, however, before we jump in, let us look at a rather handy report which is often helpful in validating customer readiness and environmental health for those looking to migrate via the Fixed Topology option.

London VMUG – 15th July 2021

Reading Time: < 1 minute

Earlier this month, I was honoured to have been able to present at the London VMware User Group. My session focussed on a discussion and demonstration around how we can leverage VMware vRealize Network Insight (vRNI) to visualise applications, their dependencies, and their application traffic flows to effectively micro-segment an application using the VMware NSX-T Distributed Firewall (DFW).

North East England VMUG – 26th September 2019

Reading Time: 4 minutes

That didn’t disappoint! I’ve wanted to visit the North East England VMUG for sometime, so being asked to present at the user group made it all the more special. As I sit here in Newcastle International Airport waiting for my flight home, I thought I’d summarise the event for those who’ve never been to a VMUG event, are thinking of doing so in the future, or are thinking of speaking at a local VMUG.

North East England VMUG – 26th September 2019

Reading Time: 2 minutes

The next North East England VMUG will be taking place on Thursday 26th September at the Royal Station Hotel, Newcastle, and I’m excited to be presenting alongside so many fantastic individuals from throughout the vCommunity.

My session will be covering VMware NSX Data Centre for vSphere (NSX-V) and, more specifically, a real world look at micro-segmentation and the implementation of a zero-trust environment. NSX makes this fairly easy thanks to a number of built-in tools, and we’ll explore how we can use the NSX Application Rule Manager to visualise application dependencies in order to start fleshing-out our Distributed Firewall rules.
