No longer do organizations have the responsibility of ensuring uptime, maintaining hardware and networking equipment, or replacing old equipment. Platform as a service (PaaS) or application platform as a service (aPaaS) or platform-based service is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. The infrastructure may be owned, managed and operated by the organization, a third party or some combination, and it may exist on or off premises. IaaS also saves enterprises from having to buy more capacity to deal with sudden business spikes. For an organization's information technology, infrastructure management (IM) is the management of essential operation components, such as policies, processes, equipment, data, human resources, and external contacts, for overall effectiveness. Information security means protecting information (data) and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction.. Information Security management is a process of defining the security controls in order to protect the information assets.. Security Program []. Cloud computing has been credited with increasing competitiveness through cost reduction, greater flexibility, elasticity and optimal resource utilization. What is cloud computing? Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) PaaS, or Platform-as-a-Service, is a cloud computing model that provides customers a complete platform—hardware, software, and infrastructure—for developing, running, and managing applications without the cost, complexity, and inflexibility of building and maintaining that platform on-premises.. The classic definition of a Data Warehouse is architecture used to maintain critical historical data that has been extracted from operational data storage and transformed into formats accessible to the organization’s analytical community. Cloud computing is a trending topic, and although it is much debated, few speak about how it will affect information technology (IT) organizations. This means that _____. Key features A well-designed information system rests on a coherent foundation that supports responsive change—and, thus, the organization’s agility—as new business or administrative initiatives arise. asked Jun 12, 2016 in Business by NoBeef. As our IT infrastructure has evolved from traditional datacenters to hybrid cloud infrastructure, so have our tools for managing IT infrastructure. These components include hardware, software, networking components, an operating system (OS), and data storage, all of which are used to deliver IT services and solutions. In practice, it leverages the methods and tools of engineering in conceiving, developing, operating and maintaining cloud computing systems and solutions. Public Cloud: The development platform is built on infrastructure provisioned for use by multiple organizations (also known as a multi-tenant model). Because the cloud is a broad collection of services, organizations can choose where, when, and how they use cloud computing. The focus of I&O leaders is evolving far beyond technology elements like data centers, colocation and the cloud to instead encompass more about how an organization’s I&O can support and enable business strategy. IT infrastructure can be deployed within a cloud computing system, or within an organization's own facilities. Your group is going to have some structure whether it chooses to or not. Years ago I drew a diagram of a generic IT organization’s structure, but upon revisiting it today I realized how many changes in IT departments I had left out. The Organization resource is the root node of the Google Cloud resource hierarchy and all resources that belong to an organization are grouped under the organization node. However, I consider server operating systems and directory services (like MS Active Directory) to be part of the infrastructure. Cloud computing is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user. Infrastructure refers broadly to the basic physical systems of a business, region, or nation. Introduction []. 11.2 Multiple-Choice Questions 1) Developing, operating, and maintaining an organization's computing infrastructure is a major function of the _____ department. This led me to speculate about what changes cloud will cause to happen in the near future. Network infrastructure is a part of IT infrastructure of an organization. ‘It recognises the infrastructure in place and the level of service we can provide here.’ ‘This is not intended to be a political debate about ownership of the infrastructure.’ ‘We are exploring new avenues where we can use our vast infrastructure to earn profits.’ CH 11 MIS QUIZ Developing, operating, and maintaining an organization's computing infrastructure is a major function of the _____ department information systems Every IS user has a right to a secure computing environment. Infrastructure software is perhaps the most “gray” of all infrastructure components. Here are a few situations where cloud computing is used to enhance the ability to achieve business goals. Infrastructure as a service (IaaS) The most basic category of cloud computing services. Organizations should take a business viewpoint and look at how to optimize costs and how to use the right tools to build their case for a given infrastructure deployment. management-information-systems Also, because organizations are relying on a particular service provider's infrastructure and software, there is a potential problem of vendor lock-in with PaaS environments. Developing, operating, and maintaining an organization's computing infrastructure is a major function of the _____ department. Structure in any organization is inevitable-- an organization, by definition, implies a structure. With Azure as the primary platform for infrastructure, we are adopting Azure management tools for monitoring, updating, backup, and security. Infrastructure-as-a-Service (IaaS) is a cloud-computing offering in which a vendor provides users access to computing resources such as servers, storage and networking.Organizations use their own platforms and applications within a service provider’s infrastructure. It might as well be the structure which best matches up with what kind of organization you have, what … A) human resources B) information systems C) marketing D) manufacturing. Network infrastructure is the hardware and software resources of an entire network that enable network connectivity, communication, operations and management of an enterprise network. Large clouds, predominant today, often have functions distributed over multiple locations from central servers. It provides the communication path and services between users, processes, applications, services and external networks/the internet. The Organization is the top of the hierarchy and does not have a parent. Creating and maintaining consistent procedures ... thoughtful steps in the right direction will get your organization up to its optimal operational ... reliable network infrastructure. Definitions: Infrastructure engineering ensures that the IT infrastructure is sufficiently robust, scalable, and efficient to deliver the integrated services underlying the physical environment that supports the processes, physical resources, and operators required for developing, integrating, operating, and sustaining IT applications and support services. Infrastructure is the foundation or framework that supports a system or organization. Governance of cloud computing is challenging even with a single cloud provider involved and becomes even more challenging as organizations move toward multicloud. As with other significant developments in technology, many vendors have seized the term cloud and are using it for products that are outside of the common definition. Cloud computing is on-demand access, via the internet, to computing resources—applications, servers (physical servers and virtual servers), data storage, development tools, networking capabilities, and more—hosted at a remote data center managed by a cloud services provider (or CSP). Maintaining clarity within an organization means that employees have a completely clear picture of all aspects of their jobs. In other words, workers and supervisors alike should know what the employee’s goals are as well as the individual tasks required to reach those goals. Enterprise IT infrastructure typically refers to components required for the existence, operation and management of an enterprise IT environment. Infrastructure and operations (I&O) is becoming increasingly involved in unprecedented areas of the modern-day enterprise. In computing, information technology infrastructure is composed of physical and virtual resources that support the flow, storage, processing and analysis of data. The network infrastructure is responsible for maintaining both internal and external connectivity of the internal and external systems. What is PaaS (Platform-as-a-Service)? A) human resources B) information systems C) marketing D) manufacturing Answer: B 2) Which of the following statements is true of an IS department? The term is generally used to describe data centers available to many users over the Internet. All resources except for organizations have exactly one parent. Cloud providers offer on-demand, self-service resources with endless capacity, making it difficult for organizations to gain visibility into, and manage, what is being consumed. Organizations with a smaller IT infrastructure generally require a smaller IT staff as well. Infrastructure software. With IaaS, you rent IT infrastructure—servers and virtual machines (VMs), storage, networks, operating systems—from a cloud provider on a pay-as-you-go basis. Examples include roads, sewer systems, power lines, and ports. Cloud computing is a broad term that describes a wide range of services. It can be internal to an organization and deployed within owned facilities, or deployed within a cloud computing system, or a combination thereof. It brings a systematic approach to concerns of commercialization, standardization, and governance of cloud computing applications. Information system infrastructure and architecture. 1.
