With the advent of cloud computing, control of networks and storage has shifted to providers. Businesses (or consumers) have retained some control on features like operating systems and deployed applications, as well as certain other items, but the characteristics of a company that offers IAAS are usually standard.
Traditional Characteristics of IaaS Providers
The concept of infrastructures as a service are new to many business owners, and it’s essential to understand the scope and characteristics of an IaaS provider. Here’s what the National Institute of Standards & Technology (NIST) has listed as the standard features of an IAAS provider.
Services are measured. The cloud system offered by the IAAS should have measuring capability designed to help optimize the network, as well as control various systems. Services that may fall under these automated controls may include bandwidth, storage, and the number of active users. These measuring systems can provide constant monitoring, as well as reports at various intervals.
Services are scalable. The services offered are easily scalable either through automatic means or simple physical modification. Scaling of services can be done at any time and for any amount, so the process is simple and straightforward for the consumer.
Resources are pooled. One of the benefits of cloud computing is that services can be scaled up through pooled resources. Various physical resources, as well as virtual resources, may be reassigned at will to accommodate the needs of the consumer. Although it’s often not possible for the consumer to exact complete control over the location of his or her services, there is usually some control over the general region or country used.
Broad network access. The network is accessible through industry-recognized or standard means whether the consumer is using a thick or thin client platform.
Changes made on-demand. The user of IAAS should have the ability to conduct on-demand changes that don’t necessarily require human interaction. For example, the user can choose features like storage capability and network connectivity.
The Three Service Models
There are three different models for these services which include Cloud Infrastructures as a Service (IaaS), Cloud Platform as a Service (PaaS), and Cloud Software as a Service (SaaS). Here are the basics of each.
Cloud Infrastructure as a Service (IaaS)
The consumer can manipulate storage, networks, and processing, as well as other basic resources for computing and install various types of software like operating systems and applications. The consumer doesn’t have access to the actual physical infrastructure of the cloud, but he or she may have some control over certain components.
Cloud Platform as a Service (PaaS)
The consumer may deploy applications to the cloud that are based on a variety of programming languages and may be offered tools by the provider for this purpose. There is no management of the cloud infrastructure by the consumer, but he or she may control items like the operating system and may also have some control over certain networking components.
Cloud Software as a Service (SaaS)
Consumers access the cloud through applications offered by the provider and usually access those applications through a web browser (also known as a “thin client interface). The consumer is not responsible for managing any part of the cloud infrastructure or the various applications used to access the cloud.
Service Deployment Models
There are four deployment models associated with cloud infrastructure which include the following:
- Community Cloud
- Hosted Private Cloud
- Private Cloud
- Public Cloud
The community cloud and public cloud fall under the heading of “shared” services while the private cloud and hosted private cloud are dedicated services. The community cloud and private cloud are run on the customer’s premises while the public cloud and hosted private cloud are part of a service provider’s data center.
