VMworld 2020 Demo – Voice activated workload migration to VMware Cloud SDDCs

10/19/2020 by William Lam 2 Comments

One of my favorite but also most stressful part of preparing for a VMworld session is creating the demos. Even with a "virtual" VMworld this year, I personally felt it was even more stressful than a physical VMworld.

I have been presenting with Emad Younis for a number of years now and every year, we always end up with crazy ideas without thinking through all the feasibility aspects. This year was certainly no different and while working on our demo this year, I was seriously questioning my sanity and even the actual return on investment (ROI), if such a thing exists!? 😂

In case you have not watched our session, check out HCP132: Planes, Trains and Workload Mobility, you can watch it for free and see the full demo.


I was really floored by all the positive feedback that we had received from attendees which includes the VMworld survey but also on Twitter and Slack. This was one of my favorite tweet and response 😀

Best session I have seen so far👏😁

We really appreciate all the feedback and it definitely made up for some of the late nights where I was about to give up. I know a few of you were asking for more details about the demo and so this blog post will be focusing on some of the information I was not able to get to during the VMworld session.

Forwarding vCenter Events into AWS EventBridge using vCenter Event Broker Appliance

01/14/2020 by William Lam Leave a Comment

After attending Mike Deck's AWS reInvent session last year on Building event-driven architectures faster than ever with Amazon EventBridge, I could not help but draw a number of parallel concepts between AWS EventBridge and our recently released vCenter Event Broker Appliance (VEBA) Fling. I thought it was a very interesting solution and certainly wanted to give it a try as I think it could really benefit some of our customers, especially for those already using our VMware Cloud on AWS solution and being able to take advantage of the various AWS Services in an event-driven fashion.


In fact, one of the use cases that I had in mind was one that we had from a VMware Cloud on AWS customer who wanted to take a vCenter Event and forward that off to AWS CloudWatch. The solution that I had shared last year was utilizing our vRealize Log Insight Cloud solution which is integrated into VMware Cloud on AWS and leveraging its webhook functionality to call into a AWS Lambda function which would then process the payload directly into CloudWatch. Although this solution works and I know several customers who have implemented something similiar, I think EventBridge could certainly provide a more flexible way to integrate not only with CloudWatch but almost any AWS Service or 3rd party service.

Running sk8s (Simple Kubernetes) on VMC with an AWS Elastic Load Balancer

02/27/2019 by William Lam Leave a Comment

Last week I wrote about a really nifty Virtual Appliance called sk8s which can be used to quickly setup a Kubernetes (k8s) cluster for development and testing purposes. If you have not checked out that article, be sure to give that a read first to get the full context. As mentioned in the previous article, sk8s runs great on any vSphere deployment but it can also run on VMware Cloud on AWS (VMC) which adds an additional capability where an AWS Elastic Load Balancer (ELB) can automatically be provisioned and configured to front-end the k8s control plane as part of the deployment for external access.

The nice benefit of this is that you only need to configure access to the ELB and not directly to the underlying VMs running within the SDDC, both simplifying the setup but also reducing the need to expose the VMs directly to the internet. The write-up below is similar to that of the previous article, but it does expand into greater detail when deploying to VMC and all the required configuration changes within the VPC using the AWS Console and the Network and Security changes using the VMC Console.

Note: If you decide to use the integrated AWS ELB integration, please be aware that you will be charged for the consumption. For pricing, please see the AWS documentation here.

Prerequisites:

  • Access to the VMC Console and VMC SDDC
  • NSX-T Logical Network with DHCP enabled
  • AWS Access & Secret Key for automatically creating ELB (Optional)
  • govc

Step 1 - Install govc on your local desktop which has access to your VMC vSphere environment. If you have not installed govc, the quickest way is to simply download the latest binary, below is an example of installing the latest MacOS version:

curl -L https://github.com/vmware/govmomi/releases/download/v0.20.0/govc_darwin_amd64.gz | gunzip > /usr/local/bin/govc
chmod +x /usr/local/bin/govc

Step 2 - We need to verify a few settings in the AWS Console to ensure that the VPC that is connected to your SDDC is properly configured so that the provisioning of the ELB will be successful.

Community stories of VMware & Apple OS X in Production: Part 10

12/19/2014 by William Lam 2 Comments

Company: Fitstar
Software: VMware vSphere
Hardware: Apple Mac Mini

[William] - Hi Clay, thanks for taking some time out of your schedule this afternoon to talk with us regarding one of the projects are you are currently working on. Before we get started, can you quickly introduce yourself and your current role within VMware?

[Clay] - Good morning and thanks for having me! My name is Clay Alvord, and I am a Senior Prototype Engineer, here at VMware. I work with hardware vendors as they develop new equipment, and get it in the hands of the developers here. It allows our engineers to get early access to pre-release gear, in the hope that as the equipment comes to market, it's on our HCL at the same time. It also allows us to help debug the hardware as its developed, so we don't hit any critical surprises after release.

[William] - Thanks Clay, very cool role! So, I hear you have been working closely with a new startup who has built a really interesting design involving VMware & Mac Mini’s? Could you provide us some more details around the design and the type of application/workload the customer has planned for this infrastructure?

[Clay] - Thats exactly right. FitStar deals with a lot of high resolution video, so their storage requirements are above average for a company their size. Most of their servers live in Amazon's EC2 cloud, and so they are already heavy users of Amazon's services. Amazon has a product called Amazon Storage Gateway (ASG). ASG allows for local storage to be mirrored to EC2, or have the your most commonly access EC2 files cached locally.

What I have designed is a local storage array, with a an Apple Mac Mini running ESXi 5.5 and Amazon's Gateway (local) storage. This gives the users the speed of local storage, with the safety-net of having their data in EC2 at the same time.

[William] - How many Mac Mini’s are they currently running on-premises and what hardware configuration did the customer choose for their specific application requirements? Were there any constraints that you had faced due to the limited resources the Mac Mini’s provided?

[Clay] - They have 1 Mac Mini, and 1 Dell Poweredge. The Mac was a hard requirement, because the original design required us to run OSX server.

We opted for the Mac Mini as it fit the budget better, when compared to a Mac Pro. The Mac Mini is a Late 2012 and has a 3Ghz cpu, with 16GB of ram. Our biggest constraint is the memory in the system. We run 2 storage gateway VM's on the dell. Each one requiring 8GB of memory. We could not have it all on the Mac Mini as the Mini only supports 16GB in total and does not have room for future growth.

The Mac Mini has 3 Mac OS X VMs. 2 of them are OS X 10.10, each running OS X Server. One for dedicated Xcode buildbot, and app caching. The other for Time Machine services. The 3rd VM is running Mac OS X 10.9 Server and is purely for file sharing.

Here is a picture of Fitstar's setup:

Here are some additional physical and logical diagrams of the setup:

fitstart-diagram2 fitstart-diagram3
[William] - How much storage is currently being managed today and how is that presented to the VMs? Do they have plans on increasing either the storage or compute platforms as they grow?

[Clay] - The storage array has 2 RAID-6 luns, serving a total of 20TB to the Dell host over iSCSI. The host then breaks up the storage into 1TB disks that are then attached the two ASG VMs. The VMs, mirror the data to Amazon and then present new iSCSI targets to the Mac Mini host. From there we use Raw Device Mappings to attach the file server and backup server.

[William] - This looks like a really cool solution that you’ve architected with the customer. For a startup, I was kind of surprised to hear they went with vSphere versus going down an open source route and potentially using some type of Cloud Services? Do you know what the motivation was that lead the customer to choose vSphere and running an on-premise solution?

[Clay] - The motivation of going ESXi over an alternative solution had several factors. The first was Fitstar's familiarity with VMware, as well as my own. The second was this solution is the backbone of their company and they needed a world class solution that has not only a strong support system, but a HUGE community behind it. Lastly, it was the hard requirement to use ASG. Using ASG allows for the volumes to be directly mounted in a EC2 instance in case of an emergency. Amazon also states that the ASG vm's are optimized for ESX and Hyper V.

[William] - That is great to hear that even for startups, having an enterprise and highly available platform such as vSphere is critical to their business. Were there any challenges while designing and deploying this infrastructure, either from a deployment or operational point of view?

[Clay] - Definitely. This project was originally designed with just file services in mind. The original POC was a local storage array, and the Mac Mini. The Mini would run a ASG and 1 OS X VM.

When it was decided that we needed Xcode, Caching and Time Machine services, we opted for a dedicated VM for each of theses. The reason is that if there were issues or heavy load with any of them, it would not affect the others.

Some of the other challenges we had was getting iSCSI to play well with Mac OS X. We were planning on having the iSCSI connections go directly to the VMs, and bypass ESXi, but 3rd party drivers don't work with Amazon's version of iSCSI. As a result, we now connect to the hypervisor, and use raw mappings to the VMs. We opted for raw mappings so that if we mount a volume in EC2, it sees a HFS+ disk, not a VMFS one with HFS inside.

We also had trouble getting the OS X server services to work on virtualized hardware. ultimately we adjusted the vm parameters to expose the hardware ID's to the vm, and so OS X thinks it running on physical hardware.

We are still working on plenty of tweaks to the system. I have seen a  OS X panic, and kernel logs point at VMware Tools as the culprit. We have filed a bug for this. We also have an issue that the nics in the Mac Mini are e1000, not e1000e. This occasionally leads to a PSOD. The work around we plan on introducing is Thunderbolt to ethernet adapters.

The last ESXi related hurdle is that in order for the VMs on the Mac Mini to auto start, the Dell and AGS VMs must be online, and the Mini has to have already scanned its storage adapters. So in the event of a power outage, when everything powers up, you must rescan storage on the mini, after the Dell is online, then power up the Mini's VM's. We have installed a battery backup unit, and are in the middle of automating the scan and power up of the Mini's VMs.

[William] - Clay, thank you very much for taking the time and sharing with us some of the innovative things our customers are doing with Apple and our vSphere platform. I really enjoy hearing about how our customers push our software to its limits and find new use cases that we had never thought about. Thanks again for sharing. Finally, before I let you go, do you have any words of advice or tips for other customers having similar requirements, especially those coming from a Startup? Any particular resources you recommend them checking out before getting started?

[Clay] - It was my pleasure. virtuallyGhetto has been a great resource for me in standing up the project. I have some tips and tricks related to this and some other things on my site www.geeksnthings.com as well.​
