Introduction Regardless of the complexity and variety existing in biological beings, living organisms are built from basic building blocks or fundamental units of life: cells. These small units execute functions, such as transportation and conversion, using a set of standardized structures (for example, the nucleus, cytoplasm, and organelles) that work together towards the proper functioning of the biological being to which they belong. Similarly, an enterprise IT architecture uses building blocks or operating environments to create, process, and transform information that supports the operations of the business organization. In this context, standardized operating environments (SOEs) represent a key concept in the simplification and normalization stages of data center optimization. Standardized operating environments act like the cells of a biological being by forming the building blocks of the IT architecture, by providing processing power, storage, software, and services. These operating environments are defined according to their place in the architecture's logical tiers, and they are shaped according to the systemic qualities (availability, performance, reliability, security, and so on) defined by the organization. The purpose of this article is to provide a better understanding of the following topics: ● A definition of standardized operating environments (SOEs) ● The place of SOEs within the enterprise IT architecture ● Templates for SOEs ● A practical guide for developing and transitioning to SOEs ● Provisioning alternatives ● Governance linkages What Are Standardized Operating Environments? Operating environments are computing and operational units that belong to the overall architecture of a data center. A standardized operating environment is a unit that is plugged into a tier of the IT architecture and has the responsibility of of moving transactions, executing instructions, and providing a service. A Route to Standardized Operating Environments 6 A unit is self-contained and has processing power and memory, an operating system, middleware, and business applications or services configured through the following four categories (the “Ss”): ● Systems, which consist of hardware resources (the servers, I/O, memory, computing power, and so on) ● Software, which is divided into three areas: ● Operating systems (what actually runs and controls the hardware resources) ● Infrastructure software (management and monitoring, messaging,

  • Standard Operating Environment Guideline
    STANDARD This guideline outlines the scope OPERATING and approach to the Computer Desktop Standard Operating ENVIRONMENT Environment (SOE) implemented by GUIDELINE Massey University. This guideline is intended to apply to computers and devices owned by Massey University and supported by Information Technology Services. Standard Operating Environment Guideline Purpose Massey University Information Technology Services (ITS) support a Standard Operating Environment (SOE) for desktop and notebook computers. The SOE is designed to ensure that the large number of desktop and notebook computers provide the necessary functionality to staff and students; can be loaded with a standard software image, maintained, updated, audited and repaired by ITS staff in a manner that improves availability and reliability, with a minimum disruption to staff and students; and at a cost that is appropriate to the University. The delivery of the Standard Operating Environment (SOE) to client computers is achieved through automated deployment and management tools. The expanded use of automation tools across all levels of ITS infrastructure, systems and services is designed to minimise support costs. The maintenance of desktop computers is most efficiently managed and delivered through the deployment of operating systems, software applications, patches and updates via online desktop management applications and tools. As part of its objective to provide cost effective and efficient management of ICT resources, Information Technology Services (ITS) maintains a Standard

  • Common Operating Environment – the Journey of Smart It Interoperability for Enterprise
    COMMON OPERATING ENVIRONMENT – THE JOURNEY OF SMART IT INTEROPERABILITY FOR ENTERPRISE LIM Tze Kwang Terence, HO Hao Xiang, TAN Kim Hong ABSTRACT The computing environment is constantly changing, triggered by Operating System and software patches, hardware driver updates, introduction of new device models and new IT systems. The Common Operating Environment (COE) comprises the client configuration, hardware, enterprise IT systems and back-end infrastructure. COE testing and certification is essential to maintain the interoperability, stability and security posture of the environment, leading to increased user productivity, reduced IT support cost and improved IT systems usability. This article describes DSTA’s journey in managing and transforming the COE. It expounds on the current landscape, processes and challenges involved, including increasing system vulnerabilities and patches, speed of testing and deployment, as well as improving the realism of test environments. The article also elucidates DSTA’s continuous efforts in introducing automation tools and technologies, undertaking smart optimisation of processes and transforming the operations model from a task-centric to a service-centric one. Keywords: COE, testing, certification, usability, automation INTRODUCTION With the increase in cyber threats and patches, regular feature upgrades and specific user demands, the COE is enhanced and refreshed constantly.
