Brian graf virtualization, business, and more… electricity 4th grade worksheet


You’ve been there. Running a long PowerShell script that you know will take more than a few seconds (maybe minutes or even hours). electricity video ks1 Either you are running the script and leaving it up on a second monitor, or you are periodically alt-tab’ing back to it to see it’s progress. Either way, I’ve started using the Windows notifications to inform me of progress with my scripts and I have to say, I really like it. I decided as I was using it this weekend that I would finally throw it into a function and post it on Github. I do not recall where I originally found this ability, but I have since taken it and modified it for my needs.

Set-TaskbarNotification allows users to create popup notifications in the bottom-right of their screen from PowerShell. In the images below, I have the command I ran and the notification popup that corresponded to each command. As you can see, this is very simple and straightforward and can allow users to continue on with their day-to-day tasks, while still receiving updates from scripts they are running.

With the announcement of the VMware Cloud on AWS Single-Host, customers are seeing the value of this offering and wanting to move to a 4-node Production SDDC. We are happy to announce that we have now released the ability to expand a Single-Host SDDC to a 4-Host SDDC without having to delete your environment and start over. This is very advantageous for customers who don’t want to sping up a new SDDC if they decide to increase the size of their environment.

The idea of our Single-Host offering is that our customers can quickly and easily spin up an SDDC and give VMware Cloud on AWS a run with their environments to see if it meets the requirements for their use cases: Once customers experience the benefits of VMware Cloud on AWS, VMware then provides a seamless method to transition from a Single-Host offering to 4-Node that will allow them to expand quickly and enable all features of VMware Cloud on AWS as well as begin to receive greater support from VMware.

Today (June 20, 2018), At the AWS Public Sector Summit in Washington DC, VMware announced VMware Cloud on AWS GovCloud. This offering will bring the ease, simplicity, and agility of moving to the cloud to those running workloads in GovCloud. VMware Cloud on AWS Govcloud operates similar to our regular VMware Cloud on AWS offering, however, GovCloud being designed to allow U.S. government agencies and customers to run their sensitive workloads requires stricter regulatory and compliance requirements.

For those who have not kept up as much on the VMware Cloud on AWS offering, it is a joint offering between both VMware and AWS to provide customers with a true hybrid cloud. VMware offers this as a service, providing customers with the hardware, software (VMware vSphere, ESXi, vCenter Server, NSX, Hybrid Cloud Extension (HCX), and vSAN in the base offering, Site Recovery (DR) as an add-on), and support. VMware provides all maintenance, patching, and support of this offering, allowing customers to focus on running their workloads, rather than managing and maintaining the infrastructure.

It’s official! I’m excited to announce that VMware Cloud on AWS now has an easier way for you to quickly deploy and use our service. We are now offering 1-node/1-host Software-Defined Data Centers (SDDC’s) for customers to be able to quickly and easily try out this offering. By deploying a 1-node SDDC, you will be able to test out the features and functionality of VMware Cloud on AWS at a fraction of the cost. These 1-node SDDC’s are fully self-service, paid for by credit card (or HPP/SPP credits), and deployed in just under two hours.

This offering gives you a 30-day single-host SDDC. There is a banner in the console that will keep you informed of how much time your SDDC has left. The SDDC is deployed just like a 4-node SDDC, just with less hosts (same number of management VMs), giving you the ability to test VMware Cloud on AWS and its features, with your specific use-cases. VMware Cloud on AWS includes:

You may deploy additional SDDC’s at the end of the 30-day countdown for the initial SDDC. However, all one-node offerings are currently set to expire at the end of the 30 days for lifecycle and security purposes. These are meant to allow you to quickly trial the offering, test integrations, and take advantage of the cloud integrations we have with AWS Services.

VMware Cloud on AWS comes with 16TB NVMe (raw) per host, which equates to 64TB raw when you create a 4-node cluster. Granted, vSAN configurations will consume part of that so the usable space is roughly 10TB/host. la gastritis That being said, there may be specific criteria of application data that you want running on your NVMe drives, and other data that is classified as ‘lower tier’. If that is the case, one of the options you have with VMware Cloud on AWS is to leverage Amazon Elastic File System (EFS) for additional data. electricity and magnetism purcell pdf You can think of EFS as a very simple and easy to use Network File Share. A single EFS can be added to multiple VMs if you choose to do so, or to single VMs.

As we’ve discussed in previous blog posts, we need to allow traffic between our AWS services and our VMware Cloud on AWS SDDC. To do that we need to enable two rules in the Compute Gateway firewall. For the purposes of this post and my others, I’ve kept this simple with allowing all traffic types to flow in and out of my SDDC. If you are doing the same, you will need to mimic my first two firewall rules, adding the ‘All Connected Amazon VPC’ as this covers the ENI traffic.

Now that we have the prerequisites out of the way, we can go ahead and create our EFS that we will attach to our VMs. Once we’ve created an EFS, we will take the IP address of the mount in the same Availability Zone as our SDDC and use that. The reason we don’t use the DNS name is because our VMs are not pointing to the same DNS servers as our EC2 instances are, hence, trying to mount from the DNS name would fail. Using this internal IP address will also ensure that the traffic goes across the ENI rather than potentially across the Internet Gateway.

It’s no secret that one of the many benefits of using vSphere is vMotion, the ability to migrate running workloads (with no downtime) from one physical host to another. In vSphere 6.0 we announced the ability to perform long-distance vMotion and cross vCenter vMotion. This paved the path for customers to now do full-on live vMotions from their on-premises data centers to VMware Cloud on AWS. This is truly application mobility at its finest! Customers can now vMotion workloads bi-directionally both from the vSphere Client as well as from tools such as PowerCLI (script below).

To allow vMotion traffic to enter and exit the Management Network in VMware Cloud on AWS, we need to establish two firewall rules, Ingress and Egress. In the ‘Network’ tab of the VMC console, go to the Management Network and expand ‘Firewall Rules’. You’ll need to allow vMotion (TCP 8000) in from your on-prem network CIDR and change the destination to ‘ESXi’. For the Egress rule, the source will be ‘ESXi’ and the Destination will be the on-prem network CIDR. Here I let any traffic back through.

As mentioned previously in this post, the L2VPN consists of NSX in VMware Cloud on AWS (This part is pretty much configured for you) and either a bespoke NSX Edge appliance (or full NSX). I will not cover the step to configure L2VPN in NSX here, but a quick Google will give you loads of information on it. You can also check out this doc HERE. electricity cost per month Once you’ve enabled L2 VPN and get the ‘Connected’ status

VMC has two separate networks. Management (used by vCenter, ESXi, NSX, etc) and Compute (All the customer workloads are placed here). The L2VPN allows us to stretch the compute network between on-prem and VMC. However, for Management communication to occur, we still need VPN connectivity to the Management network. This is where the Layer 3 VPN comes in to play. Once your VPN has come online, we can move on and configure Hybrid Linked Mode.

Hybrid Linked Mode allows users to manage their on-prem environment AS WELL AS their cloud environment, from a single pane of glass. As you can see in the image below, I have my VMware Cloud on AWS SDDC at the top, followed by my on-prem environment below it. This is because I went through the setup steps to add the on-prem identity store to my Cloud SDDC. Now I can login to my VMC vCenter with my on-prem credentials, see both environments, and even perform vMotions from this console (keep reading!)

Alright! Now that we’ve gone through our prereqs we can start to use our wonderful vMotion. Within the vSphere Client, right-click on the workload you want to vMotion up to VMware Cloud on AWS, and click on ‘Migrate’. Select Change both compute resource and storage, select the desired resource pool in VMC, select the workloadDatastore, select the desired folder, choose the correct stretched network, and finish. You’ll see the vMotion task begin in the vSphere Client, followed by the VM appearing in the VMC vCenter. Note that once the vMotion is complete, the vSphere Client icon for that VM will look like it is powered off. gas hydrates are used It is still powered-on and a quick click of the refresh icon at the top of the client will show it correctly.

So, that was cool to be able to live-migrate workloads across datacenters and up to the cloud with just a few clicks of the mouse. I’ve done these migrations back and forth because I find it so exciting *nerd alert*. But what if you want to migrate VMs in bulk? Nobody wants to sit there and migrate workloads one VM at a time. We’ve got a great PowerCLI script for you. On-Prem to VMC

In this scenario, I have four (4) front-end apache servers running in my VMware SDDC. These do not have any public IP addresses associated with them and no NAT’ing configured. What we’re going to do is create an AWS Application Load Balancer (ALB) that will route to the internal IP addresses of the VMware VM’s even though they do not reside within the VPC of the Load Balancer. Kinda cool, right?

If we take a look at each of these virtual machines you’ll notice that they all have private IP addresses ( This is important to understand as we move forward. Keeping track of their private IP addresses, we move on to create the target group that will be used by the AWS Application Load Balancer. (*Note: We already set up our firewall and security group rules in the previous blog posts.)

In the AWS Console, under EC2 > Load Balancing > Target Groups, we have a target group we created for these Apache VMs. When registering the targets, instead of pointing them to a VPC, we point them to ‘Other Private IP’. We then enter the IP addresses of the four VMs. As you can see in the image below, we’ve added all four targets and they all appear to be healthy.

Now that we’ve got our target group that our Application Load Balancer will consume, we can go ahead and create the Load Balancer. Creating an Application Load Balancer (ALB) is very straightforward so I won’t cover all the steps to create it. What you do need to ensure though, is that the VPC that is chosen at creation is the VPC that is connected to your VMC SDDC. Also add port 80 and your target group as a ‘Listener’, and you will be good to go.

Once created, our ALB gave us an address of: (feel free to try out the link!) Each of my Apache VMs is running a simple static website with a title, the name of the VM, and an image of the VMware Cloud on AWS overview slide. Once you are on this page, try refreshing multiple times and you will see that it is hitting each of the different VMs from the Target Group.

What’s really neat about this is that I no longer need to deploy my own software load balancer in the VMware stack. gas blower will not start There is no additional updating or maintenance I need to perform with my load balancer as I am now using one provided by AWS. Remember, all of these Apache VMs were using their private IP addresses and I did not have to configure additional NAT’ing rules or add Public IPs to my VMware Cloud on AWS SDDC just to resolve these VMs. They are all leveraging the Elastic Network Interface (ENI) connectivity between the VMware stack and their AWS services. Something you won’t find anywhere else. This opens up endless possibilities for customers to design and implement their datacenter application architecture.
