VMware Cloud (VMC) Console Inventory with various vSphere "Linked Modes"

06.28.2023 by William Lam // 1 Comment

While I have covered a number of popular topics across our vSphere+, vSAN+ and VCF+ Cloud Service in my recent 7-part blog series, which I definitely recommend folks check out first, direct links below:

  • vCenter Cloud Gateway
  • vCenter Lifecycle Management
  • vCenter Desired State Configuration
  • VM Provisioning & Management
  • Cloud Consumption Interface (CCI)
  • Global Inventory for vSphere
  • Subscription & Entitlement

One reoccurring theme that has come up and for good reasons is what users would see in the VMware Cloud (VMC) Console as it pertains to the different types of vSphere-based deployments from vSphere+, VCF+ and VMware Cloud on AWS (VMC-A), especially when incorporating the different "Linked Mode" configurations that are supported today?

New SDDC Linking capability for VMware Cloud on AWS

11.03.2020 by William Lam // 1 Comment

Back in September, the VMware Transit Connect (vTGW) on VMware Cloud on AWS (VMConAWS) feature was released and provides users a simplified way of connecting AWS VPCs, AWS Direct Connect Gateways and customer on-premises datacenter from a networking connectivity standpoint. As part of this feature, a new logical construct called an SDDC Group was created which allows customers to easily apply common networking connectivity policies across a number of SDDCs versus having to manage them separately which can quickly get complex from an operational point of view.

The SDDC Group not only simplified the initial setup, but it also simplifies Day 2 Operations when new SDDCs are provisioned and added to the SDDC group. The networking policies that have been configured at the SDDC Group will automatically apply to all new SDDCs which makes this a really slick solution. As SDDCs are removed from the SDDC Group, the related configurations are automatically un-provisioning and detached from the respective networking resources.


Simplified network connectivity using an SDDC Group was just the beginning! Today, the VMware Cloud team has released a new feature built on top of the SDDC Groups construct called vCenter Linking for SDDC Groups. Just as the name implies, customers can now easily "Link" multiple vCenter Servers within an SDDC Group enabling a single view of all vCenter Servers using any one of the vSphere UIs within the SDDC. For those familiar with Enhanced Linked Mode (ELM), this is basically that but for SDDCs running in the Cloud!

The workflow could not have been simpler and last week I got try it out and was quite impressed! Under the hood, this leverages the vCenter Convergence capability and when enabling vCenter Linking, the service automatically handles all those details including the necessary NSX-T firewall rules that need to be configured across ALL SDDC to allow for secured connectivity. Just imagined having to do this each time a new SDDC is added or remove, you need to manually go to all SDDC and update or create new firewall rules!? This is all hidden away from the user and by simply associating SDDCs in the SDDC Group, the configurations are applied automatically for you.

Just setup an upcoming feature which builds on top of VMware Transit Connect Gateway (vTGW) allowing #VMWonAWS customers to now “Link” multiple SDDCs together. Just 1-Click, you now can access all Cloud vCenter Servers using any one vSphere UI. ELM for Cloud!#VMwareCloud pic.twitter.com/dImg6Yloe3

One question that I did have while trying out this new feature was how does this work with existing features such as Hybrid Linked Mode (HLM) and ELM?

Enhancements to Hybrid Linked Mode (HLM) in VMC using the new vCenter Cloud Gateway

10.04.2018 by William Lam // Leave a Comment

It has been almost a year since VMware introduced the Hybrid Linked Mode (HLM) capability, which provides customers with a consistent operating experience for managing and consuming resources from both their on-premises and VMware Cloud on AWS (VMC) environments. Feedback from customers on HLM has been fantastic, especially when new or prospective VMC customers learn about HLM for the very first time. Customers were pleasantly surprised at how seamless the experience was when consuming VMC resources, using a familiar interface, the vSphere UI.

Here is a quick recap of what HLM provides today:

  • HLM allows customers to link a single VMC instance to a single on-prem SSO Domain which can contain one or more vCenter Servers (Enhanced Linked Mode) while maintaining separate administrative domains (e.g. on-prem user is Administrator while VMC user is CloudAdmin only)
  • SSO Domains will be different between on-prem and VMC, however it is a 1:1 relationship
  • A trust is established where the on-prem vCenter Server trusts the incoming connections from VMC as they share the same Active Directory identity source. Data is sync'ed uni-directionally from on-prem to VMC
  • Can be configured at any point in the on-prem vCenter Server lifecycle, no restrictions to initial install and can easily be un-linked unlike ELM
  • Both Embedded & External vCenter Server deployments are supported
  • HLM supports different versions of vCenter Server between on-prem (6.5d+) and VMC, especially as VMC will almost always run a newer version of vSphere
  • Users MUST login to VMC vCenter Server for single-pane of glass management (H5 Client supported only), logging into on-prem vCenter Server will NOT show VMC vCenter Server
  • Roles are NOT replicated due to the restrictive access model in VMC
