The future of the ESXi Embedded Host Client

by // 14 Comments

As many of you know, the ESXi Embedded Host Client project is something that is very near and dear to my heart. I have always felt that we needed a simple web interface that customers can just point their web browser to an ESXi host after a new installation and be able to quickly get started. One of the biggest benefit in addition to simplicity is that it is also very intuitive from a user experience standpoint which I believe is very important in a world where things can quickly get complex. In addition, it can also provide an interface for basic troubleshooting and support greenfield deployments where vCenter Server has not been deployed yet.

It has truly been amazing to follow the Embedded Host Client development from the initial idea to the first prototype built by VMware Engineers Kevin Christopher and Jehad Affoneh to its current implementation lead by Etienne Le Sueur and the ESXi team. I have really been fortunate to have had the opportunity to be so involved in this project. It is hard to imagine that in just little over 6 months, we have had had 5 releases of the Embedded Host Client Fling, all of which, produced with high quality development and rich feature sets.

You can click on the links below to get more details about each release.

I think its an understatement to say that customers are genuinely excited about this project as well, just look at some of the comments left on the Flings page here. Interestingly, this excitement has also been felt internally at VMware as well and I think this goes to show that the team has built something really special that affects anyone who works with VMware's ESXi Hypervisor.

So where to do we go from here? Are we done? Far from it ...

For those of you who follow me on Twitter know that I had recently refreshed my personal vSphere home lab from a Apple Mac Mini to latest Intel NUC running the yet to be release VSAN 6.2 (vSphere 6.0 Update 2). I was pleasantly surprised to see that ESXi Embedded Host Client (EHC) is now included out of the box with ESXi! Although this has been said by a few folks including myself, it is another thing to actually see it in person 🙂

Although the VMware Flings program is a great way to share and engage with our customers to get early feedback, it may not always be a viable option. As some of you may know, Flings are not officially supported and this sometimes prevents some of our customers from engaging with us and really putting the Flings through its paces. By making EHC out of the box, not only are we officially supporting it but it will also make it easier for customers to try out this new interface.

UPDATE (03/04/16) - It looks like I made a mistake and that the ESXi Embedded Host Client will NOT be released as a "Tech Preview" as previously mentioned but rather it will be officially GA'ed with vSphere 6.0 Update 2. EHC is a fully supported feature of ESXi.

Although EHC is very close to parity with the vSphere C# Client, it is still not 100% there. We will continue to improve its capabilities and if you have any feedback when trying out the EHC, do not hesitate and leave feedback or file a Feature Request through GSS. For those looking to live on the "edge" a bit more, we will still continue to release updates to the EHC Fling but if you want something that is stable, you can stick with the stock EHC included in ESXi 6.0 Update 2. We will still ship the legacy Windows vSphere C# Client, so you will not be forced to use this interface. However, it is no secret that VMware wants to get rid of the vSphere C# Client and that EHC is the future interface to standalone ESXi hosts.

One feature that I know that many of you have been asking about is Free ESXi. Well, I am please to say that support for Free ESXi has been added in the latest version of EHC included with the upcoming ESXi 6.0 Update 2 release and below is a screenshot demonstrating that it is fully functional.

Lastly, I just want to say that EHC has really morphed beyond just a "simple UI" for managing standalone ESXi hosts and has also enabled other teams at VMware to do some really amazing things and create new experiences with this interface. As I said earlier, this is just the beginning 😀 Happy Friday!

Here are some additional cool capabilities provided by EHC

vSphere SDK for JavaScript Fling released

by // 2 Comments

The VMware Fling team has just released another cool new Fling, the vSphere SDK for JavaScript. This Fling is especially interesting as it provides the underlying SDK framework used by the popular ESXi Embedded Host Client Fling which was released back in August of last year. I came to learn about this project during last years internal R&D Innovation Offsite (RADIO) conference which is held annually and can be thought of as the VMworld conference for VMware employees.

One of the biggest highlight of the conference for me personally is checking out the expo floor where you get to see what other VMware Engineering teams have been working on whether it is the next big feature, product or new ideas that they might be thinking about. It was during my walk through that I met Rostislav Hristov, one of the Engineers who worked on the vSphere SDK for JavaScript. I was really impressed at what Rostislav built and luckily he was already in touch with the Embedded Host Client Engineers to see how they could leverage his JavaScript SDK as the initial prototype had made calls directly using the vSphere MOB which was not very friendly to develop against.

There has been a number of improvements to the vSphere SDK for JavaScript since I last saw it and although the name contains "vSphere", it definitely supports more than just the vSphere API endpoint. In fact, with this single SDK you can interact with vCenter Server Single Sign-On (SSO) API, vCloud Suite API which covers capabilities like Tagging and Content Library as well as the Site Recovery Manager (SRM) APIs! For customers and partners that are looking to develop their own web portals or interfaces that can integrate with these APIs, this will be a handy tool to have.

To get started, the vSphere SDK for JavaScript contains a README file that contains additional instructions on setting up the SDK as well as a couple of samples that demonstrates each of the supported API endpoints:

  • vimService.js - Sample using the vSphere API
  • stsService.js - Sample using the SSO API
  • cisServices.js - Sample using the vCloud Suite API
  • srmService.js - Sample using the SRM API

Here is the command to run the vimService.js sample which will also require you to set the environmental variable NODE_TLS_REJECT_UNAUTHORIZED=0 if you are using the default VMware self-signed SSL Certificate.

NODE_TLS_REJECT_UNAUTHORIZED=0 babel-node samples/vimService.js

Once the sample has started up, you will be prompted with a URL to open in your browser. In the vimService.js example, you will be able to login to either a vCenter Server or ESXi host as seen in the screenshot below.

vsphere-sdk-for-javascript-1
Once logged in, you should see a simple listing of the different inventory objects in your vSphere enviornment.

vsphere-sdk-for-javascript-2
In the stsService.js sample, once logged in by specifying the address to your PSC/SSO instance, you should see that a SAML token was issued.

vsphere-sdk-for-javascript-3
The cisService.js sample exercises several operations using a mixture of both the vSphere API as well as the new vCloud Suite API. It does require connecting to a vCenter Server 6.0 environment as it will be performing operations using the new vSphere Content Library feature as well as some VM operations. Do not worry, once the operations have been completed, the script will automatically clean itself up. This is a great sample if you want to see how you could make use of the different APIs all through this single SDK.

vsphere-sdk-for-javascript-4-new
I did not have an SRM environment up and running to test the srmService.js sample, but you can see from the code that it will list all of the recovery plans and their current state. For more details on how the individual APIs work, you can refer to the documentation included in the vSphere SDK for JavaScript or the official API documentation for the individual products. If you have any feedback or comments about this Fling, please leave a comment on the Fling site here as I am sure the Engineers would love to hear what you think!

How to bootstrap the VCSA using the ESXi Embedded Host Client?

by // 5 Comments

In the past, I have written about various ways of "bootstrapping" vCenter Server (here and here) which can be useful for setting up greenfield vSphere deployments. This topic has always been of interest to me because it can be the most challenging to solve, especially when you only start out with a single ESXi host. Historically, these "bootstrapping" options have mostly been driven from a CLI standpoint which is not a bad thing when you think about it from an Automation standpoint and needing to replicate this a few dozen times. However, from a user experience point of view, it may not be as ideal, especially if this is an infrequent task. One of the other cool features of the ESXi Embedded Host Client (EHC) which recently had its v4 release is that it can be used to deploy Virtual Appliances stored in the OVF format.
