Reading Notes for Class 13, Self-Paced Ops 201

Objective

Today's reading is relevant to what we are studying in lecture as it introduces the concept of cloud virtualization, specifically using AWS.

Reading Comprehension (1)

Title = Important of Virtualization in the Amazon EC2 Cloud

  1. How has virtualization evolved beyond desktops and servers? The same model that VMWare used which allowed anyone to virtualize a traditional computer with all its resources has extended to now cover the network, storage, data devices, as well as applications.
  2. In the context of the Amazon IaaS Cloud Service Model, what does EC2 stand for? Amazon Elastic Compute Cloud - an IaaS service that provides virtual servers based on the Xen hypervisor. The hypervisor in this case acts as a virtual machine manager that sits on top of the host system where all of the customer virtual machines run.
  3. What types of storage does EC2 use, and how is EC2 web traffic managed? EC2 instances use the storage through either Ephemeral (temporary) or Elastic Block Storage snapshots stored in Amazon S3. Further, CloudWatch monitors AWS cloud resources and how EC2 web traffic is load balanced.
  4. What are the benefits of service-oriented architecture for customers of EC2 virtualized services? The biggest advantage is the ability to control virtualization through a web interface, as well as the ability to manage the entire system through API.
  5. Analyze how cloud virtualization can promote equitable access to technology resources across diverse populations. How can this technology bridge cultural gaps and empower underserved communities? Cloud virtualization can promote equitable access to technology resources as it provides users with the capabilities of having an advanced system/network setup, without having to own/having access to the hardware that this used to require. This is especially useful for communities that do not have the same software/hardware infrastructure setup as we have in Western cultures, and in this way, it ultimately helps to bridge the technology gap for individuals and communities that have a desire to learn more/access information that they were not previously able to.

Title = AWS Cloud Practitioner Essentials: Amazon EC2 Overview (Video)

  • Amazon Machine Image (AMI) = template that contains the software configuration (OS, application server, and applications) required to launch your instance
  • Security group = set of firewall rules
