Introduction to Cloud
Fichas del conjunto (7)
- 1The US National Institute of Standards and Technology (NIST) defines cloud computing as?A model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. Examples of computing resources include networks, servers, storage, applications, and services.
- 2Resource pooling –uses a multitenant model –resources are dynamically assigned and reassigned according to demand without customer concern regarding the resource’s physical location is an example of ?Five Essential Characteristics of the Cloud
(1.On-demand self service –processing power, storage, and network via simple interface without any human interaction.
2.Broad network access –via the network through standard mechanisms and platforms such as mobile-phones, tablets, laptops, and workstations.
3.Resource pooling –uses a multitenant model –resources are dynamically assigned and reassigned according to demand without customer concern regarding the resource’s physical location.
4.Rapid elasticity –access more resources when you need them or scale back when you do not.
5.Measured service –only pay for what you use or reserve.) - 3What are the Three Types of Cloud Deployment Models?1- Public –cloud services are leveraged over the open internet on hardware owned by the cloud provider, but its usage is shared by other companies.
2.Private –the cloud infrastructure is provisioned for exclusive use by a single organization. It could run on premise or be owned, managed, and operated by a single operator.
3.Hybrid –a computing environment that connects an organization’s on-premises private cloud and a third-party public cloud into a single flexible infrastructure for running applications and workloads. - 4Which Service Model provides access to physical computing resources, such as servers, storage, networking, and data center space without need to manage or operate?Infrastructure-as-a-Service (IaaS) – provides access to physical computing resources, such as servers, storage, networking, and data center space without need to manage or operate.
- 5The use of two or more clouds from different cloud providers defines?Multicloud
(the use of two or more clouds from different cloud providers. This can be any mix of IaaS, PaaS, or SaaS. For example, you may consume email as service from one vendor, customer relationship management (CRM) from another, andIaaS from yet another) - 6What is Hypervisor?A small software layer that enables multiple operating systems to run alongside each other, sharing the same physical computing resources.
A hypervisor also separates the VMs logically, assigning each its own slice of underlying computing power, memory, and storage, thus preventing the virtual machines from interfering with each other. - 7—
