Chapter 1. What is Oracle Public Cloud?

Cloud computing is the latest and most successful evolution of distributed computing. It has been very well adopted by the scientific and commercial communities. The main reason behind its success is the elasticity and pay-per-use payment model. By elasticity, we mean the resources are provisioned and released as per user requirement, and in the pay-per-use payment model, users are billed only for their actual resource usage.

This chapter discusses various cloud services offered by Oracle and the architecture of the Oracle Cloud Services. Finally, the chapter discusses how to get trial access to the services.

The following topics will be covered in this chapter:

  • A brief review of cloud computing concepts

  • Oracle Cloud Services

  • Application Services

  • Social Services

  • Platform Services

  • Common Infrastructure Services

  • Oracle Managed Services

  • Architecture of Oracle Cloud solution

  • Trying Oracle Public Cloud Services

 

Brief review of cloud computing concepts


National Institute for Standard and Technology (NIST), USA has defined cloud computing, and this is the best starting point to understand the fundamentals of cloud computing. The definition is as follows:

"Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (for example, networks, servers, storage, applications, and services) that can rapidly be provisioned and released with minimal management effort or service provider interaction."

The cloud model proposed by NIST is composed of five essential characteristics, three service models, and four deployment models.

Essential characteristics

The five essential services defined by NIST are as follows:

  • On-demand self-service: This enables users to provision and manage computing resources, such as server time, amount of storage, and network bandwidth, without a need for human administrators.

  • Broad network access: Cloud services and capabilities must be available and accessed from heterogeneous platforms, such as personal computers and mobile devices.

  • Resource pooling: Provider resources are shared among multiple consumers, and these physical and virtual resources are automatically managed according to consumer demand.

  • Rapid elasticity: Resources can be elastically provisioned and released to rapidly scale out and scale in as per user need.

  • Measured service: Cloud provider resources should be tracked for usage by its consumers for the purpose of billing, generally on a pay-per-use basis.

Service models

Cloud services are available in the following models:

  • Software as a Service (SaaS): When application software is deployed over a cloud, it is called Software as a Service; for example, Oracle planning and budgeting and Salesforce CRM. Consumers can access this application software from heterogeneous devices without having to worry about the management of hardware, network, and operating system. The user only needs to manage some application-specific settings, if required.

  • Platform as a Service (PaaS): Platform as a Service provides an application development platform in the form of a cloud service; for example, Oracle Java Cloud Services, the Google App engine, and so on. Consumers need not bother about the management of hardware, network, and operating system and only supposed to manage application deployment and configuration settings.

  • Infrastructure as a Service (IaaS): Similarly, hardware infrastructure is made available to its consumers using Infrastructure as a Service clouds, for example, Oracle IaaS/Amazon's Elastic Compute Cloud . Consumers need not to manage the hardware infrastructure but have full control over the operating system, development platform, and application.

Deployment models

Cloud services can be deployed using one of the following four Cloud deployment models:

  • Private cloud: In a private cloud, the cloud facilities are operated only for a specific organization. It can be owned or managed by the organization, a third party, or a combined entity and can be deployed within the organization or on some other location.

  • Community cloud: A community cloud is shared by multiple organizations of similar concerns such as goals, mission, and data. It can be owned or managed by several organizations from the community, a third-party, or a combined entity and can be deployed within the organizations or on some other location.

  • Public cloud: A public cloud is open for a large user group or can provide open access for general users. The public cloud is generally managed by business, academic, or government organizations.

  • Hybrid cloud: A hybrid cloud is a blending of private, community, or public clouds.

 

Oracle Cloud Services


Oracle offers a range of services for all the cloud service models. These services are as follows:

  • Oracle SaaS Services include customer relationship management, human capital management, and enterprise resource planning. These applications cover almost all of the requirements of any commercial application.
