Cloud Computing Exam (A+ GRADED)

What is Cloud Computing? correct answers It is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility over a network. The resources are dynamically scalable and often virtualized. It is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort. Cloud Resources correct answers They are usually not only shared by multiple users but are also dynamically reallocated per demand. Companies can scale up as computing needs increase and then scale down again as demands decrease. Moving to Cloud correct answers Move away from a traditional CAPEX model (buy the dedicated hardware and depreciate it over a period of time) Adopt the OPEX model (use a shared cloud infrastructure and pay as one uses it.) What does Cloud Computing mean? correct answers It means storing and accessing data and programs over the Internet instead of your computer's hard drive. What does Cloud Computing allow? correct answers It allows users to access and use program through a web browser as if they were installed locally on their own computers. Examples of Cloud Computing correct answers Google Drive, Google Cloud Platform, Apple iCloud, Microsoft Azure & OneDrive, Amazon EC2, Amazon Simple Storage Service S3, IBM SmartCloud, Oracle Cloud What is Resource Planning? correct answers The provider's computing resources are pooled to serve multiple consumer using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. Benefits of Cloud Computing correct answers Empowerment, Agility, Productivity, Capital expenditure-operational expenditure, Device and location independence, Reliability, Scalability and Elasticity, Security, Maintenance.
