The capability provided to the consumer is the provision of processing, storage, networking, and other basic computing resources on which the consumer can provision and run any software, including operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure, but can control the provided operating system, storage, and applications, and may have limited control over selected networking components such as host firewalls.

1. The Illustrating OpenText Cloud Models, Here It Is!
With so many cloud models, such as infrastructure-as-a-service, platform-as-a-
service, multi-tenant SaaS, and dedicated cloud hosting services, it's easy to get
overwhelmed and confused about what's right for your business needs.
In this Bentech Article, we provide an overview of the available cloud services
and deployment models defined by NIST and define a cloud model for
OpenText. Cloud computing is a model of on-demand access to shared
computing resources that can be rapidly deployed and shared by administrators
or service providers with minimal effort or interaction.
Cloud service Model
The three service models of the cloud are as follows:
• Infrastructure as a Service (IaaS)
The capability provided to the consumer is the provision of processing, storage,
networking, and other basic computing resources on which the consumer can
provision and run any software, including operating systems and applications.
The consumer does not manage or control the underlying cloud infrastructure,
but can control the provided operating system, storage, and applications, and
may have limited control over selected networking components such as host
firewalls.
2. • Platform as a Service (PaaS)
Consumers can deploy in the cloud consumer-built or purchased applications
created using the provider's supported programming languages, libraries,
services, and tools. The consumer does not manage or control the underlying
cloud infrastructure, including networking, servers, and operating systems or
storage, but has control over deployed applications and possibly configuration
settings of the application hosting environment.
• Software as a Service (SaaS)
The consumer uses the provider's application running on the cloud
infrastructure. Applications can be accessed from various client devices through
a thin client interface such as a web browser or a program interface. Consumers
do not manage or control the underlying cloud infrastructure, including
networking, servers, operating systems, storage, or even individual application
functionality, except for limited user-specific application configuration settings.
3. Deployment Model
NIST defines four deployment models:
• Private Cloud
Cloud infrastructure is intended for exclusive use by a single organization
spanning multiple consumers (for example, business units). It may be owned,
managed, and operated locally or externally by the organization, a third party,
or a combination thereof.
• Community cloud
Cloud infrastructure is intended for use by a specific community of consumers
from organizations that share common concerns such as mission, security
requirements, policy, and compliance considerations. It may belong to, be
managed, and operated by one or more organizations in the community, third
parties, or a combination thereof, and may exist on-site or off-site.
• Public cloud
The public openly uses cloud infrastructure. It may be the property,
management, and operation of a company, academic or governmental
organization, or a combination thereof. It is located on the cloud provider's
premises.
• Hybrid cloud
A cloud infrastructure consists of two or more distinct cloud infrastructures
(private, public, or public) that remain distinct units but are connected by
standardized or proprietary technologies that support data and application
portability (e.g., with Cloud bursting for load balancing between clouds).
Define an OpenText Cloud Model
4. Based on the above definitions, OpenText Cloud is suitable for a combination of
PaaS and SaaS service models and private and hybrid delivery models. Elements
defined by Public Cloud and Community Cloud apply to OpenText Cloud.
However, they are not available to the public, only to OpenText commercial
customers. Because of this distinction, we refer to OpenText's cloud offering as
a private/hybrid cloud, rather than a "public cloud" in this document, although
OpenText Cloud offers a shared cloud infrastructure (virtualized and logically
separated between customers).
