Reproductionis Strictly Prohibited Understand Cloud Computing Fundamentals Cloud computing delivers various types of services and applications over the Internet. These services enable users to utilize software and hardware managed by third parties at remote locations. Major cloud service providers include Google, Amazon, and Microsoft. This section introduces cloud computing, the types of cloud computing services, the separation of responsibilities, the cloud deployment models, the NIST reference architecture and its benefits, the cloud storage architecture, the cloud service providers, fog computing, and edge computing.

Introduction to Cloud Computing Cloud computing is an on-demand delivery of IT capabilities in which an IT infrastructure and applications are provided to subscribers as metered services over a network. Examples of cloud solutions include Gmail, Facebook, Dropbox, and Salesforce. Characteristics of Cloud Computing The characteristics of cloud computing that attract many businesses to adopt the cloud technology are discussed below. * On-demand self-service: A type of service rendered by cloud service providers that provides on-demand cloud resources such as computing power, storage, and network, without the need for human interaction with service providers. = Distributed storage: Distributed storage in cloud offers better scalability, availability, and reliability of data. concerns. = However, it can potentially involve security and compliance Rapid elasticity: The cloud offers instant provisioning of capabilities to rapidly scale up or down according to demand. The resources available for provisioning to the consumers seem to be unlimited that can be purchased invariably in the desired quantity. = Automated management: By minimizing user involvement, cloud automation speeds up the processes, reduces labor costs, and reduces the possibility of human error. = Broad network access: Cloud resources are available over the network and can be accessed through standard procedures via a wide variety of platforms, including laptops, mobile phones, and PDAs.

Certified Cybersecurity Technician Virtualization and Cloud Computing = Exam 212-82 Resource pooling: The cloud service provider pools all the resources together to serve multiple customers in a multi-tenant environment, wherein the physical and virtual resources are dynamically assigned and reassigned on demand by the consumers. = Measured service: Cloud systems employ the “pay-per-use” metering method. Subscribers pay for the cloud services via monthly subscriptions or according to the usage of resources such as the storage levels, processing power, and bandwidth. Cloud service providers monitor, control, report, and charge the customers according to the resources consumed with complete transparency. = Virtualization technology: It enables the rapid scaling of resources in such a way that could not be achieved by non-virtualized environments. Limitations of Cloud Computing = QOrganizations have limited control and flexibility = Prone to outage and other technical issues = Security, privacy, and compliance issues = Contracts and lock-ins = Dependence on network connections Module 10 Page 1304 Certified Cybersecurity Technician Copyright © by EC-Gouncil All Rights Reserved.
