Amazon AWS & Microsoft Azure Part 1. - Virtual Machines

I was very keen to learn about these two CLOUD giants namely Amazon's AWS & Microsoft's Azure.  So I started to explore about them that how are they similar and different from their offering perspective.

Both of them are Public Cloud offerings as most of the people are aware of it. So let's just start.
Azure has near to 68 offerings that one can choose from their big list whereas AWS has near to 100 offerings. Further, you can check their offerings on other blog posts. Like TOM's IT ProT has a very good comparison of it.

Starting with their Virtual Machine Related Services:-

AWS - EC2 ( Elastic Compute) & Azure Virtual Machines (Compute)

Here you can choose from a wide variety of Virtual machine instances that you can deploy and start using. So will start how to create a VM in EC2 and end with AWS Virtual machine.


Step1. Need to setup an account for AWS & Azure .

AWS has various type of Instances available, in layman's terms size of virtual machines. I"ll be using a Free Tier instance which will be T2.Micro

Similar way how to create a EC2 instance, you can check on  Amazon tutorials as well.

Azure has different size of Virtual Machine available.

Installing PowerShell & PowerCLI in MAC OS

Mac Install 

Install These are the detailed instructions. 

Step 1 - Download PowerShell for MAC and need to check whether it allows you to install if gives you an error related to the unidentified application. To resolve this, click the Apple symbol in the menu bar and open System Preferences > Security & Privacy and then click Open Anyway.
Installed will be there and install.

Step 2 - Make sure you did not miss this step from the PowerShell installation instruction:

brew install openssl brew install curl --with-openssl 

Step 3 - Create the following directory if it does not exists by running the following command: 

mkdir -p ~/.local/share/powershell/Modules 

Step 4 - Extract the PowerCLI modules into the directory you created above by running the following command: 

unzip PowerCLI.ViCore.zip -d ~/.local/share/powershell/Modules 

unzip PowerCLI.Cis.zip -d ~/.local/share/powershell/Modules 

unzip PowerCLI.Vds.zip -d ~/.local/share/powershell/Modules

Renew the IP of VMkernel port if assigned from DHCP.

While working with one of vSAN HomeLab, i have assigned VMkernel port to get IP from DHCP and I should have assigned it on different subnet but did on the same subnet as of vMotion.
So, without removing and re-creating the vmkernel port i have came across this esxcli command:



esxcli network ip interface set -e false -i vmkN ; esxcli network ip interface set -e true -i vmkN

esxcli network ip interface ipv4 get

no element found line 1 column 0 in vSphere Replication

While working with SRM, I came across the problem with vSphere Replication that

no element found line 1 column 0 

in its VAMI console i.e https:\\vSphereReplicationIP:5480.

Its there because one vSphere Replication Appliance can only be registered with one vCenter Server and once it is done , if somehow there is error in the communication between vCenter & vSphere Replication Server you"ll end up getting this error.

How I resolved this.

1. Removed the solution user present in users and group for the designated vSphere Replication Appliance.
Solution User will be like : com.vmware.vr-UUID of vcenter Server.

2. Try and reinstall the certificates of vSphere Replication from VAMI console.

3. Now it should work.
