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

Last night, I received a pleasant and surprising email, you can see the details in the screenshot below:

This was a surprise because it was something I was tinkering around with back in March (8months ago!) to see if I could some how generate notifications when changes were being made to a specific component/device on the VMware HCL also known as the VCG (VMware Compatibility Guide). I suspect many of you have used the VMware HCL at least once if not many more times and as you can imagine, it would be nice to be able to get notifications or alerts when something has changed for a particular component or device that you might care about.

I was thinking about this problem because at the time I was interested in receiving updates on a particular VSAN disk controller. While browsing through the HCL, I had noticed there was an RSS feed icon located on the upper right hand corner for each component/device as shown in the screenshot below.

I thought maybe I could do something interesting with that? I decided to use one of my favorite SaaS services IFTTT (If This, Then That) which I have blogged about in the past on how to send SMS notifications using vCenter Server Alarms. I found an RSS to Email IFTTT recipe and created a notification based off of one of the Intel RAID Controllers by specifying the RSS feed URL.

I knew this was going to be a bit difficult to test given the HCL does not get updated that frequently and even if it does, I have to be monitoring the right device that received the update. I completely forgot about this recipe until yesterday when I had received the email stating an update had been made to this device. I guess it worked after all 😀 If there specific things you care about on the VMware HCL and you want to be able to receive notifications for any updates, you can create several IFTTT recipes that can either send you an email or notify you through some other method. I think this is a pretty nifty trick instead of continuously checking the VMware HCL every so often for changes, unless you are looking for brand new component/device that has not been added to the HCL.
