The cloud is the elastic leasing of pooled computer resources over the Internet. To fully comprehend the cloud, we must know the meaning of the terms elastic and pooled. Elastic means that the computing resources leased can be increased or decreased dynamically, programmatically, in a short span of time and that organizations pay for just the resources that
they use. Cloud resources are pooled because many different firms use the same physical hardware; they share that hardware through, as we learned, virtualization. With the cloud, the resources are accessed over the internet (for example, a Google Chromebook). The cloud is the future for most organizations for three reasons. Q2 – What Network Technology Supports the Cloud? Q3 – How
Does the Cloud Work? The cloud resides in the internet. So, in order for you to understand how the cloud works, you must know how the internet works. Individualized IP addresses are numbers that identifies a particular device. In contrast, public IPs’ identify a particular device on the public internet. Private IPs’ identify a particular device on a private network, most commonly on a LAN. A URL (Uniform Resource Locator) is an address on the Internet. (i.e. http://www.sjsu.edu) TCP and IP Protocols
Q4 – How Do Organizations Use the Cloud? There are three fundamental cloud types.
Content Delivery Network (CDN) – a system of hardware and software that stores users data in many different geographical locations and makes those data available on demand. It is used often to store and deliver content and minimize latency. Q5 – How Can AllRoad Parts Use the Cloud? AllRoad Parts can use many different SaaS products including:
AllRoad Parts could also use PaaS services, for example, leasing EC2 and Amazon.com will preinstall either Linux or Windows Server on the cloud hardware. IaaS Services at AllRoad could also provide basic hardware in the cloud, and use data storage services elastically. Q6 – How Can Organizations Use Cloud Services Securely? Virtual Private Network (VPN) – uses the Internet to create the appearance of private, secure connections. A private cloud is a cloud that is owned and operated by an organization for its own benefit. Virtual Private Cloud (VPC) – a subset of a public cloud that has highly restricted, secure access. Can be defined as the elastic leasing of pooled computer resources over the Internet?The elastic leasing of pooled computer resources over the Internet is called the cloud. A cloud is a peer-to-peer network used to share data between users. The elastic leasing of pooled computer resources over the Internet is called the cloud.
Why is the cloud described as elastic and pooled?The cloud is defined as the elastic leasing of pooled computer resources over the Internet. Cloud resources are pooled because many different organizations use the same physical hardware; they share that hardware through virtualization.
What exactly is cloud computing quizlet?What is Cloud Computing? 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.
What is the cloud and three key terms?Cloud computing is a general term for anything that involves delivering hosted services over the internet. These services are divided into three main categories or types of cloud computing: infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS).
