Cloud classifications.

Cloud computing is where the resources on the network are not actually physical in nature. They are provided to the user virtually.This can lead to a very fluid and dynamic

environment, as required resources are normally only provisioned as needed and are decommissioned once their use is completed.Most often, these virtual resources are not owned by the company that uses them, but are provided by a service provider.While cloud computing is highly configurable and changeable, it does have some basic structures that are used in the classification of the type of cloud that is in use.

Cloud concepts.


– Public cloud.» Systems can interact with services and devices within

the public cloud and on public networks (e.g., the Internet) and possibly other public clouds.

– Private cloud.» Systems only communicate with services and devices

within the specified private cloud.

– Hybrid cloud.» Combines aspects of both the public and private

clouds.

– Community cloud.» Cloud services used by private individuals,

organizations, or groups that have a common interest.

Types of cloud computing.

Because of the nature of cloud computing, it is very configurable to the needs and desires of the purchaser.

Purchasers have many options beyond the type of cloud services (e.g., public or private) that they want to provision. They must also determine what type of service they are going to require—from the most basic to the highly complex (e.g., SaaS or PaaS).

Cloud concepts.


– Software as a service (SaaS).» The end user purchases the rights to use an application

(software) without the need to configure the virtual servers that will deliver the application.

• It is usually delivered as a Web application (opened and used from within a Web browser).

– Platform as a service (PaaS).» The user is provided with a development platform for

the creation of software packages, without the need to configure the virtual servers and infrastructure that delivers it.

– Infrastructure as a service (IaaS).» The end user is provided with access to virtual servers

(configurable by the customer) and other virtual network resources.

• Creates a highly configurable environment in which customers can create the resources and performance that they require.

• The end user supplies the software that is going to be used on the IaaS network.

Cloud concepts.


It is not uncommon for the type of cloud computing being utilized by an organization to be a mix.

Some departments may use IaaS, while a development team utilizes a PaaS only. Part of the advantage of cloud computing is only initializing resources as they are needed.In a private cloud situation, it is possible for the organization that is using it to actually own the cloud resources. If they do own the cloud resources, they may have it on site, or they may pay to have the resources hosted off site.

Cloud concepts.


Cloud computing can be a great method of conserving company resources, but it also has several security considerations.

When using hosting services, there is always the need to consider confidentiality. When the resources are out of the physical control of the company, it may be difficult control access to those resources. In some situations—such as when a law requires a company to maintain physical control of the resources—cloud computing may be unacceptable.In addition to the physical control, there is also the problem of reliability and availability. The purchaser is having to rely upon the hosting service’s ability to maintain system uptime and availability.

Cloud concepts.

Always perform due diligence research to ensure that the cloud provider is both reputable and reliable. As part of the research, it is also important to evaluate whether or not the resource is appropriate to be hosted (e.g., the owner is not required to maintain physical control of it).

What was covered.Cloud concepts.

The use of cloud computing means that network resources are provided virtually instead of physically. This can lead to a very dynamic and fluid computing environment. The type of cloud deployed can be classified in one of four ways: public, private, hybrid, or community.

Topic


Summary

The highly configurable nature of cloud computing has led to several different types of cloud computing. In SaaS, only a software package is provided (usually run from within a Web browser). PaaS provides a development platform that is usually used in the creation of software packages. With IaaS, the user configures the virtual network resources that will be used—from virtual servers to the software packages. Cloud computing does raise some issues with security, mainly concerning controlling who has access to the resources, reliability, and availability. Always research the options for the appropriateness of the solution.
