Which of the following is a type of cloud computing service?

Which of the following is the application of cloud computing?

Which of the following is the correct statement about cloud types?

Choose among the following which is related to services provided by the cloud.

Cloud computing is believed to have been invented by Joseph Carl Robnett Licklider in the 1960s with his work on ARPANET to connect people and data from anywhere at any time.

Select the correct question for the above explanation (may be more then one)

In which year Salesforce.com pioneered the notion of bringing remotely provisioned services into the enterprise

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model is composed of five essential characteristics, three service models, and four deployment models.

•A layer of software allows physical IT resources to provide multiple images of a single physical machine so that their underlying processing capabilities can be shared by multiple users.

What is significant of this Image

scaling refers to adding more or faster CPUs, memory, or I/O resources to an existing server, or replacing one server with a more powerful server.

Auditor–A third-party (often accredited) that conducts independent assessments of cloud environments assumes the role of the cloud_____________

A system is capable of recovering from certain types of failure without any human intervention. It has a “convergence” or “control” loop that actively looks at the system's actual state and compares it to the state that the operators initially desired.

•The delivery model represents a pre-defined “ready-to-use” environment comprised of already deployed and configured IT resources.

•Set of pre-packaged products and tools used to support the entire delivery lifecycle of custom applications.

A cloud enables an organization to use cloud computing technology as a means of centralizing access to IT resources by different parts, locations, or departments of the organization and owned by a single organization•

The actual administration of this cloud environment may be carried out by internal or outsourced staff.

•Private systems that enterprises build in-house and operate themselves.

•These data centers can be utilized to run private cloud networks, in which resources are virtualized in similar ways to public clouds and can be used from anywhere. However, private clouds can be operated and maintained by third-party services.

A Cloud-based Data Center can be easily accessed through smart phones and other connecting devices with security credentials to allow remote working. The stored data can be retrieved, processed, or recovered with just a few clicks on the laptop. This will enable employees to carry out their work from any corner of the world in any time zone.

•Data centers are designed to operate with increasingly higher levels of redundancy to sustain availability.

•Data centers usually have redundant, uninterruptable power supplies, cabling, and environmental control subsystems in anticipation of system failure, along with communication links and clustered hardware for load balancing.

•Three fundamental elements of Web technology architecture are:

•An IT resource that actively filters network traffic to and from the isolated network while controlling its interactions with the Internet.

•The process of isolation of a network environment from the rest of a communications network.

•Cloud storage device mechanisms provide common logical units of data storage, such as:

In Network Storage Interfaces, Industry standard protocols are used, such as

1. 1. The protocol does not provide the session

2. 2. Not a reliable protocol

3. 3. The speed of communication is fast

4. 4. It is highly scalable

6. From the above properties identify the correct network storage Interface

1. 1. Scaling a relational cloud storage device vertically can be more complex and cost-ineffective than horizontal scaling.

2. 2. Scaling a relational cloud storage device horizontally can be more complex and cost-ineffective than vertically scaling.

3. 3 Databases with complex relationships and containing large volumes of data can be afflicted with higher processing overhead and latency.

4. 4. Databases with complex relationships and containing large volumes of data can be afflicted with lower processing overhead and lower latency.

5. Identify which two are true with respect to Cloud Storage Device

1. 1. Replication is typically performed when an IT resource’s availability and performance need to be enhanced.

2. 2. •Virtualization technology is used to implement the resource replication mechanism to replicate cloud-based IT resources.

1. In Resource Pooling Architecture:

2. 1. A resource pooling architecture is a grouping of identical IT resources maintained by a system that automatically ensures that they remain synchronized.

3. 2. Physical server pools are composed of networked servers that have been installed with operating systems and other necessary programs and/or applications and are ready for immediate use.

4. 3. Virtual server pools are configured with several available templates chosen by the cloud provider during provisioning.

1). This mechanism is commonly used to interface with backend systems and programs in order to provide resource pool administration features via a front-end portal

2). The resource management system mechanism supplies cloud consumers with the tools and permission management options for administering resource pools.
