Pay per use monitor in cloud computing

What is a mechanism?

a system of parts working together in a machine; a piece of machinery.

Learning Outcomes

Understand basic concepts and terminology relating to cloud computing

Understand virtualization technology

Cloud Characteristics mentioned in Chapter 4

The following six specific characteristics are common to the majority of cloud environments:

• on-demand usage

• ubiquitous access

• multitenancy (and resource pooling)

• elasticity

• measured usage

• resiliency

7.6 Ready-Made Environment

7.1 Logical Network Perimeter

Logical Network Perimeter

Defined as the isolation of a network environment from the rest of a communications network, the logical network perimeter establishes a virtual network boundary that can encompass and isolate a group of related cloud-based IT resources that may be physically distributed

This mechanism can be implemented to:

isolate IT resources in a cloud from non-authorized users

isolate IT resources in a cloud from non-users

isolate IT resources in a cloud from cloud consumers

control the bandwidth that is available to isolated IT resources

Logical Network Perimeter

Logical network perimeters are typically established via network devices that supply and control the connectivity of a data center and are commonly deployed as virtualized IT environments that include:

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

• Virtual Network – Usually acquired through VLANs, this IT resource isolates the network environment within the data center infrastructure.

7.2 Virtual Server

Virtual Server

A virtual server is a form of virtualization software that emulates a physical server. Virtual servers are used by cloud providers to share the same physical server with multiple cloud consumers by providing cloud consumers with individual virtual server instances.

7.3 Cloud Storage Device

Cloud Storage Device

The cloud storage device mechanism represents storage devices that are designed specifically for cloud-based provisioning. Instances of these devices can be virtualized, similar to how physical servers can spawn virtual server images

Cloud Storage Levels

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

• Files – Collections of data are grouped into files that are located in folders.

• Blocks – The lowest level of storage and the closest to the hardware, a block is the smallest unit of data that is still individually accessible.

• Datasets – Sets of data are organized into a table-based, delimited, or record format.

• Objects – Data and its associated metadata are organized as Web-based resources.
