Summary

Foundations of Information SystemsSummary

7.1 Fundamentals of Cloud Computing

  • On-premise IS resources provide organizations with systems that are managed and maintained by the IS staff of the organization.
  • Cloud computing has introduced a means by which organizations can provide services to their customers through the internet.
  • Cloud computing provides constant access through the internet to any device from any location.
  • Cloud computing maximizes resource use through the implementation of virtualization software, which adds scalability and elasticity for the cloud consumer.
  • There are numerous IS positions available in cloud computing, such as network engineers, system administrators, and cybersecurity specialists.

7.2 Cloud Computing Services, Pricing, and Deployment Models

  • Cloud computing incorporates a delivery model to allow consumers to build the cloud computing environment that will best handle their computing needs. Those delivery models are IaaS, PaaS, and SaaS.
  • Cloud computing has a deployment model that enables the cloud consumer to build an environment structure that meets business strategies. The deployment models are community, private, public, and hybrid.
  • Cloud computing offers consumers flexibility, scalability, and pricing variations based on usage.
  • The cost factor of cloud computing versus on-premise environments should be evaluated before organizations enter any contracts.
  • Each cloud provider is different, and the services they offer differ based on their customer profiles.

7.3 Cloud Computing Technologies

  • Technology used in cloud-based computing, such as SDNs, virtualization, and storage-area networks, provides some of the functionalities offered to cloud consumers.
  • To properly migrate to cloud-based computing, organizations must determine what migration tools are needed to complete the move to the cloud infrastructure.
  • Security of the data is essential when it comes to migrating to a cloud-based platform. Security frameworks such as NIST and the CIA triad will help with the process before, during, and after.
  • Organizations need to identify a cybersecurity framework that maximizes the protection of their data.

7.4 Cloud-Based Industry Applications

  • Organizations need a variety of cloud computing applications and must choose the category and type to be developed, purchased, or leased.
  • Organizations will encounter software or applications that the vendor stops supporting and will need to determine whether to replace the software or migrate to the cloud.
  • Organizations can research the possibility of migrating to a cloud-based application versus on-premise deployments.
  • In a migration strategy, organizations can determine if the application migration can be automated to reduce costs.

7.5 Scientific, Industrial, and Social Implications of Cloud Computing

  • The evolution of technologies and software has moved cloud-based computing into the mainstream of business.
  • Ethics must drive an organization’s use of data because of social implications and data privacy laws and regulations.
  • Cloud-based computing will need to continue to look at new forms of revenue to accomplish sustainability.
