VMware NSX: An introduction

After server and desktop virtualization, VMware is now focusing on network virtualization. Essentially the company has been focusing so far on the 'compute' market for Virtualization and now it has started working on a similar product for Network.

Lets admit it, Networks take more time to provision. With virtualization coming in, the creation of Servers, desktops etc now takes minutes when compared to hours/days/weeks situation in the pre-virtualization era. But if we have a new network requirement for the VMs, it can be sorted to an extend using vSwitch. What if the requirement goes beyond that? Say a router /firewall/VPN that should be used by the VM. Of course, we should get in touch with the networking guys and it could take some time for the stuff to get sorted out

With NSX, Vmware aims to address this bottle neck. The idea is to provision,backup and manage networks similar to how you manage your VMs now. There will be logical switches,routers, firewalls and VPNs.You can create virtual networks using these logical devices, connect your VMs to them , backup your network topology,create templates and deploy on demand. Your underlying physical network will act as the "packet forwarding backplane" as per VMware.

Interesting concept actually!! Would love to see how this gets implemented in real world . Vmware is yet to come up with details of this, and it has already tied up with various partners like Dell,HP,Juniper networks etc to make this a reality. So the key is to wait and watch :)

Windows server 2012: where is my start button??

If you have been using Windows Server OS for a while, the one thing that will strike you most when you login to a Windows server 2012 is that there is no start button!!.. What??..How am I going to manage it?? Microsoft feels that you really dont need a start button, since you can do almost everything from your server  manager or even remotely from your desktop. After all the initial configurations are done, you could also do away with the GUI and go back to server core option.(In server 2012, there is an option to add and remove GUI). So does that mean, you need to learn to live without a start button. Actually no, the start button is very much there .Lets start looking for it. Option 1: There is "charms" bar on the side of your deskop, where you will find a "start" option. You can use the "Windows +C" shortcut to pop out the charms bar Option 2: There is a hidden "start area"in  the bottom left corner of your desktop

Use Diskpart to make drives online

Issue: In disk management, disk is shown as missing or Offline in Windows Resolution: The disks can be made online by using diskpart utility - Open a command prompt->type diskpart -Inorder to list the disks in the system type: list disk -Note down the number of the disk that you want to make online -Select that disk to operate upon, For eg:, if the disk number is 1, type: Select disk 1 -Now that particular disk will be selected as teh active disk. If you type "list disk" command once more, you can see a * symbol on the left side of the selected disk -Inorder to make the selected disk online type : online disk - If the disk is made online, you will get a message that the operation is completed successfully

Kubernetes best practices in Azure: AKS name space isolation and AAD integration

Once you have decided to run your workloads in AKS service in Azure, there are certain best practices to be followed during design and implementation. In this blog we will discuss two of these recommended practices and the practical aspects of their implementation- Azure AD integration and name space isolation While AAD helps to authenticate users to your AKS cluster using the existing users and groups in your Azure AD, name space isolation provides logical isolation of resources used by them. It is useful in multi tenant scenarios where the same cluster is being used by different teams/departments to run their workloads. It is also useful in running say a dev, test and QA environment for organization in the same cluster. Combining AAD integration with name spaces allow users to login to their namespace using their Azure AD credentials AAD integration with AKS : The following Microsoft document will get you started  with AAD integration of AKS cluster.: https://docs.microsof
