Learning Objectives

  • Summarize the alignment between governance, service, and organization needed to achieve an effective cloud security strategy
  • Describe important components of cloud security
  • Contrast the three cloud service models: software as a service, platforms as a service, and infrastructure as a service
  • Summarize essential functions listed in the cloud computing reference model
  • Contrast the three cloud deployment models: public, private, and hybrid
  • Discuss the advantages and disadvantages of cloud computing
  • Define cloud computing
  • List the steps required to deploy services to the cloud
  • Summarize how organizations move from virtualized to cloud environments
  • Describe the roles of hosts, hypervisors, and virtual machines in a virtualized environment
  • Contrast virtualized and traditional environments

VIRTUALIZATION BASICS AND CLOUD COMPUTING

1. Where does the hypervisor sit in a virtual architecture?

  • Between the hardware and the operating system(s). (CORRECT)
  • Between the operating system and the applications.
  • Between the applications and the user.
  • Remotely to coordinate tasks between different physical computers.

Correct! Between the hardware and the various operating systems.

2. Which are the first two steps to perform in a cloud deployment?

  • Integrate and Optimize
  • Automate and Manage
  • Consolidate and Virtualize (CORRECT)

Correct! First take control of your existing environment.

3. Which are the three (3) most common forms of Cloud computing?

  • Hybrid Cloud (CORRECT)
  • Private Cloud (CORRECT)
  • Universal Cloud
  • Public Cloud (CORRECT)

Partially correct. This is one of the 3.

4. Which type of cloud is the best choice for a start-up company with no existing IT infrastructure and limited funds?

  • Public Cloud (CORRECT)
  • Private Cloud
  • Hybrid Cloud
  • All of the above.

Correct! No major investments to make up front and easy to expand as the business grows.

6. Which is a primary security consideration in a cloud environment?

  • Disaster Recovery and Business Continuity Plan
  • Governance Plan
  • Compliance
  • All of the above. (CORRECT)

Correct! All of these are critical to your success in the cloud.

VIRTUALIZATION BASICS

1. Virtualization allows you to create multiple simulated environments or dedicated resources from how many physical hardware systems?

  • unlimited
  • 3
  • 1 (CORRECT)
  • 2

2. Which two steps of a cloud deployment are performed after you move your applications to the cloud?

  • Integrate and Optimize (CORRECT)
  • Consolidate and Virtualize
  • Automate and Manage

3. Which type of cloud is the best choice for a company with a robust existing IT infrastructure and very serious data privacy concerns?

  • Public Cloud
  • Private Cloud (CORRECT)
  • Hybrid Cloud
  • All of the above.

4. Which is a primary security consideration in a cloud environment?

  • Availability
  • Data Security
  • Identity and Access Management
  • All of the above. (CORRECT)

CONCLUSION – Overview of Virtualization

In conclusion, this module has provided a foundational understanding of virtualization and cloud computing, along with insights into governance, security considerations, and the benefits associated with cloud technology.

Armed with this knowledge, learners are better equipped to navigate and leverage the capabilities of virtualized and cloud-based environments effectively.
