One can deploy cloud services in different ways, according to the factors given below: * Host location of cloud computing services = Security requirements = Sharing of cloud services » Ability to manage some or all of the cloud services = Customization capabilities The five standard cloud deployment models are = Public Cloud In this model, the provider makes services such as applications, servers, and data storage available to the public over the Internet. Therefore, he is liable for the creation and constant maintenance of the public cloud and its IT resources. Public cloud services may be free or based on a pay-per-usage model (e.g., Amazon Elastic Compute Cloud (EC2), Google App Engine, Microsoft Azure, IBM Cloud). o Advantages: e Simplicity and efficiency e Low cost * Reduced time (when server crashes, needs to restart or reconfigure cloud) Module 10 Page 1315 Certified Cybersecurity Technician Copyright © by EC-Council All Rights Reserved.
