CMIT 495 Current Trends and Projects in Computer Networks and Security Week 1 – Virtualization 1 Log in to your newly created AWS account and take a screen capture of the AWS Console (Dashboard) and embed it below. Figure 1: AWS console dashboard Figure 2: AWS services 2 Provide a detailed overview of the steps required to provision (create) and launch an AWS Ubuntu-based server virtual instance. The steps may be listed in bullet points or complete sentences. Use as much space as required. From the services page Click on E2 to be redirected to the EC2 dashboard Figure 3: EC2 dashboard. Scroll down to the launch instance button. Figure 4: Launching instance Assign the instance a name Figure 5: Instance name Select the type of operating system Figure 6: Selecting an instance OS . Create a key pair that would be used for logging in. Figure 7a: Creating a key pair Figure 7b : creating a key pair. Name the key pair then select Select the key type to RSA Then select the key file format to. pem Then create key pair Figure 8: generating a ssh key pair. You can the launch the instance Figure 9 : Launching the instance. If the launch is successful, it will show a green box. Figure 10 : Successful instance launch. 3 What are the benefits of virtualization in a cloud environment? Discuss a minimum of three benefits in detail. Scalability - a virtualized cloud environment is easy to scale. As an organization keeps growing, cloud services are recommended Cost Saving - a virtualized cloud environment would be able to reduce the cost of buying hardware devices. An organization can then channel the funds of buying this equipment to other areas. Disaster recovery - in the case of disasters that affect the company's hardware devices e.g. fire, the company won be affected from such. Also, virtualization provides a better backup solution that would ensure that data is well secure and can be restored at any moment. 4 Based on your experience, what was the most challenging aspect of provisioning and launching the AWS Ubuntu-based server instance in the AWS virtual environment? Creating a key pair for logging in. 5 Configure your local host computer to use an SSH client application to interact with the newly created and running AWS Ubuntu virtual instance. If using a Windows-based local computer, read over the AWS document, "Connect to your Linux instance from Windows using PuTTY”, download and install PuTTY or use Windows 10 built-in OpenSSH client.[Link: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html] Figure 11: Connecting to instance Figure 12: ssh connection instructions. Figure 13: instance connection via ssh 6 From the local computer establish an SSH connection to the AWS Ubuntu Server virtual instance, login, and update the Ubuntu Server using sudo apt-get update and sudo apt-get upgrade. Perform a screen capture after having each command successfully run. Figure 14: performing ...
