       Create an EBS volume for the existing EC2 Machine in the same region. Requirement: EC2 Machine on a particular region.           Previously on the lab exercise, I already created an AWS account and launched an EC2 machine. Now I am going to create an EBS volume and connect it to my EC2 machine.  This is done to get extra storage for our instances.          To make those EBS volumes usable in the instances, we need to mount it to a specific folder. Now let's see how to do that. Create an EBS Volume: Step - 1: Open AWS web console and go to the EC2 dashboard. Then select Volume option under Elastic Block Store option. Step - 2: By selecting 'Create Volume', create a new EBS volume. Step - 3: Input the details like Volume type, Size, Availability Zone as per your needs. Ensure that the availability zone is same as our EC2 instance's region. Then Create Volume. Step - 4: Once our Volume is created(it...

     In storage virtualization, multiple physical disks are combined into a group and from that group of physical disks, virtual storage or logical storage blocks are assigned to a server for use.       This virtual storage will look like physical storage to a server or host, which means server cannot differentiate between physical storage and virtual storage.      Examples: LUN’s (Logical unit number), Logical volume (LV), RAID groups, etc. STORAGE VIRTUALIZATION IN VIRTUALBOX: Step-1: Open VirtualBox. Step-2: Open the settings of any Virtual Machine that you already created with which you are going to demonstrate Storage Virtualization. Step -3: Then select Shared Folders. Step - 4: Click the icon with plus on the right to add a shared folder. Step - 5: Give the folder path and folder name then mount point detail. Then Select Ok. That will create a shared folder between the host machine and the virtual machine to achieve Storage Virtua...

Requirements: EC2-parameters, IP address Puutygen, putty(windows), SSH client-Ubuntu PEM/PPK file EC2 Username&Key Aim:     To create a EC2 instance accessible via remote client in AWS. Procedure:     First to connect to an Instance, you need PuTTY which is a free SSH client that allows you to do that from our local computer running Windows.

Then set the Port to 22 and connection type to SSH. Then Select SSH on the left-side and choose the 'Auth' option under it. Click Browse to locate the .ppk file which we downloaded when we created our key pair and then select it. Click Open to connect to your Instance. If this is the first time to connect to your instance, PuTTY Security Alert will ask whether to proceed or ...

  Requirements: AWS Account ISO image Putty(Linux) / Remote desktop sever connection(windows) Putty Gen Aim:     To create an EC2 instance using AWS.
