The Illustrating OpenText Cloud Models

1. The Illustrating OpenText Cloud The Illustrating OpenText Cloud Models Models, Here , Here It Is! 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 Cloud service M Model odel The three service models of the cloud are as follows: • Infrastructure as a Service (IaaS) 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) • 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) • 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 Deployment Model NIST defines four deployment models: NIST defines four deployment models: • Private Cloud • 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 • 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 • 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 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).

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).
